Mold quality control points

Mold quality control points

A, the rationality of the mould design

Structure design is reasonable is the key to the quality of a complete set of mold, mold production cycle, so for the mold structure design and manufacturing process must attach great importance to, be sure to do reasonable as far as possible, to get twice the result with half the effort. Thus design it necessary to pay attention to the following:

plastic injection molding and china mold maker

1. When the mould structure design should pay attention to how to make the production process, easy to do. Plastic pieces of the size of some key parts (such as dimension, high precision size or contract) in areas such as the uneven tolerance reserve the direction of the steel material selection, so that need change after test module and have a chance of correction, and avoid possible welding such as remedies.

2. Mold design for putting small and more or mold eccentric structure, mould should be under the guide pillar structure. The launch of the hole for multiple rib ventilation window can decorate a few first, but pay attention to the position of the reserved (avoid water), so that can increase when necessary to launch holes or increase the rib Angle so that the mold. Strict in plastic parts shape and can't feed, try to adopt the way of diving or putting diving feed.

3. The mould design is completed, need comprehensive review all drawing size especially mutual need to fit the size and type bit size accurate, can only be a formal processing drawings, all employees participating in the mold production to each process control according to the requirements of size. Second, the quality control of mold material

We manufacture I mold are small batch or single production, processing process is complex, manufacturing cycle is long, the mould parts of raw materials for processing using even affected the quality of the mould of a complete set of, according to the present production condition, from the mold production necessary

The aspects of mould materials for quality control.

1. Should choose fixed, with stable quality assurance materials suppliers. For key mold parts material, required to provide product certification; When necessary for material composition test, inspection quality inspection, etc.

2. The material into the factory inspection work earnestly. Requirements:

1) material chemical composition is correct. (use spark discriminant);

2) good quality of materials and forging surface smooth, no obvious crack folding, scarring, slag inclusion, open side after texture

Even, no cracks, porosity, slag inclusion and other surface; 3) delivery hardness appropriate size (HRC26-32) right;

4) die set to check the datum, the parting surface precision, A and B plate material quality, and provide mould frame factory inspection requirements

The report.

3. The production process at any time to monitor quality of materials, die set, found that the problem is detailed record and feedback management personnel handling.

Life in plastic products

Life in plastic products

      

In everyday life we often see plastic are the following: polyester, polyethylene, polypropylene, high density polyethylene, low density polyethylene, polyvinyl chloride, polystyrene. In fact, these are our common "1-7" plastic.

PET: polyethylene terephthalate used to make water bottles, Coke bottles, juice bottles, screen protective film and other transparent protective film, usually colorless and transparent. Because it can heat to 70 ℃, so this only suitable for cold drink bottles and warm drink, put hot liquids (such as: hot water) or heating the deformation, there are harmful substances leaching; and the plastic products after using 10 months, may release carcinogenic, toxic to humans.

Advantages: high transparency, can see the contents of the bottle; acid, can be loaded carbonated drinks; waterproof high and difficult to bleed. Note: non-toxic, but the synthesis process may remain single, low molecular weight oligomers and side reaction products such as diethylene glycol, these are some toxic, PET raw material for beverage bottles countries have strict standards. Material PET plastic bottles can not be placed on the car sun; not install wine, oil substances, harmful substances that can dissolve it. Do not install more than 70 ℃ liquid, high temperature can cause the material decompose to release harmful chemicals.

HDPE: High density polyethylene suitable for loading food and medicines, equipment cleaning supplies and bath products, shopping bags, garbage cans, etc. At present, the use of plastic bags in supermarkets and shopping malls are mostly made ​​of such material, can withstand 110 ℃ high temperature, indicating food bags can be used to dress the food. HDPE is widely used in a variety of translucent, opaque plastic containers, thick feel.

Advantages: relatively resistant to various corrosive solutions, and more are used in cleaning products, bath products. Note: The dress cleaning supplies, bath products bottles can be reused after cleaning, but these containers are usually not wash clean, the residual material will become a breeding ground for bacteria, it is best not recycling, especially in full bloom cycle is not recommended as the Food and Drug the container uses.

PVC: Polyvinyl chloride PVC is now used for the manufacture of some cheap leather, floor mats, water pipes, etc.; due to its good electrical performance has a certain self-retardant properties, is widely used in the manufacture of wire and cable sheath. In addition, PVC is widely used in industrial fields, especially for acid corrosion in high demand areas. Commonly used in: raincoats, PVC plastic pipe lines, water pipes, plastic switches, sockets

Advantages: high strength, resistance to climate change and better corrosion resistance. Note: this material can only heat 81 ℃, and therefore can not be used at higher temperatures. Is likely to precipitate toxic when used in the production of a large number of PVC plasticizers (plasticizing agents, such as DOP) and heat stabilizers containing heavy metals, and the synthesis is difficult to eliminate the presence of free monomers, and the high temperatures encountered in oil, carcinogenic so PVC in contact with the human body, especially in medicine and food applications, replaced by the PP, PE basically.

     4, low-density polyethylene (LDPE)

Plastic film and plastic wrap, made ​​of paper milk cartons, drink boxes and other packaging are using it as an inner foil. Utensils used for the plastic film, not as a beverage container. Commonly used in: cling film, plastic film, toothpaste or cleanser hose packaging. Pros: good ductility, use in life is extremely broad. Note: LDPE products at higher temperatures due to softening or melting, should avoid the use of higher water temperatures under 100 ℃. Cling film at temperatures above 110 ℃, there will melt and, therefore, the food placed before the microwave, first remove the cling film wrapped. 5, polypropylene (PP) microwave meal made ​​using this material, resistant to 130 ℃ high temperature, transparency is poor, this is the only place in microwave plastic boxes can be reused after careful cleaning. PP high hardness and surface gloss. PP is also very broad range of use, everyday items such as packaging, toys, basins, buckets, hangers, cups, bottles, etc.; engineering applications such as car bumpers. PP spun yarn is known as polypropylene, textiles, non-woven fabrics, ropes, nets and other products are common.

Commonly used in: disposable juice, beverage cups, plastic plate, Lock & Lock crisper and so on. Pros: good air permeability, heat temperature up to 167 ℃, is the lightest plastic containers. NOTE: If the temperature is too high, the body will not have gas diffusion out. In addition, some microwave meal box body is made of PP, but the lid is made ​​of the 6th PS, carefully checked before use, if such a situation should first remove the lid after heating. Products compared to PE, PP products slightly better heat resistance, typical Lock & Lock glass using temperature can reach 110 ℃, but then there is a high temperature melting softening and dangerous, and should be avoided.

6, polystyrene (PS) used in: ice cream containers, snack, cheap transparent products, foam, CD boxes, cups, snack, insulation material layer. Advantages: transparency, heat resistance is superb, used to install high-temperature foods, such as bowl of instant noodles (now multi-use paper containers), cold resistance, a variety of ice also love to use this container.

Product quality is the lifeline of business

Product quality is the lifeline of business

In market economy increasingly developed of today, commodity quality cash we shopping centre enterprise of importance increasingly strong, commodity quality of high and low is enterprise have core competitiveness of reflected one of, improve commodity quality is guarantee enterprise occupies market, thus can hook continued operating of important means, a Enterprise wanted to big do strong, in enhanced innovation ability of Foundation Shang, efforts improve commodity of quality level for enterprise of importance, goes without saying that, does not focusing on products of quality, eventually will even, lip.

According to statistics, the average lifespan of an enterprise is only 7 years, who ruthlessly eliminated by market enterprises may have a variety of issues of internal management and external market conditions deteriorated, but there is no doubt that enterprise are planted in many shopping centres do not pay attention to the quality of goods this link. Quality is more important than ever today, is because the market environment compared with the era of commodity shortages, fundamental changes have taken place, as long as they can produce will sell off the era is gone. Successful Mall enterprises without any exception attach importance to the quality management of goods. Important issues of quality management is the Mall survive today, highlights the importance of the quality of goods. A small, kuiyuyixue, imagine if to ensure the quality of not strictly, then they would damage the interests of consumers, caused by beginning enterprise image will plummet, the products unsalable will be inevitable. Doing quality work, is everyone's responsibility. Therefore, pay attention to product quality problems, are also important issues of today's enterprise development must be taken into account. Quality is the foundation of Mall business, no quality, talk about development, competition is hot air. For Mall business for us, quality is the cornerstone of our survival and development. In my opinion, if an enterprise wants to build its own brand, quality is one of the indispensable conditions. Just like a machine, is comprised of thousands of different parts tie into a function, effects depend on each part of a machine up and running properly, feature is played out, with the accuracy. And quality, is this one of the parts. Only by giving full play to the role of each component, in order to ensure the normal operation of the machine. Quality is the cornerstone of business survival, quality is the development of "golden key", in other words the quality is enterprise's life. "People-oriented and focus on quality, standardize management, continuous improvement, customer satisfaction" is our eternal principle of service and corporate philosophy. In short, quality is the foundation of the enterprise, the quality is enterprise's life. Only put the emphasis on quality in the work of the first, to catch it as life, meticulous, excellence, always maintaining high quality and efficiency, only in this way in order to remain invincible in the fierce competition.

Plastic applications

Plastic applications

We specialize in precision injection mould design, manufacture and precision injection molding.

Tidy on plastic materials based on many years of work experience in the practical application of experience:

One feature 1, definitions of commonly used plastics materials: plastic plastic is a synthetic or natural polymers as the main constituent of substances usually contain additives such as secondary ingredients, broadly speaking, he is a certain temperature and pressure could create a certain shape of plastic polymer organic material. Published in 1996, the new national standard (GB/t 2035-1996) plastics redefined as: polymers as the main ingredient, and at some stages of processing into finished products can flow molding materials.

2, the composition of the plastics: Plastics is the main ingredient of synthetic resin, coupled with some additives and fill material.

A,----of synthetic resins and synthetic organic macromolecular compound, its structural unit mainly consists of carbon, hydrogen, oxygen atoms and others such as sulfur atoms and silicon atoms by chemical bonds, and other connections. -----B, fill materials with glass fiber, carbon fiber, calcium carbonate (CaCO3), silicon dioxide (SiO2), cotton cloth, metal, wood flour, asbestos, mica and stone powder.

C, additive---------common plasticizers, stabilizers, lubricants, colorants, antistatic agent, flame retardant, UV-resistant agent and so on.

3, in General, plastic materials can be divided into two categories: "thermoplastic plastics" (Thermoplastic) and "thermosetting plastic" (Thermosetting). Thermoplastic plastic at room temperature, typically a granular, heated to molten state after a certain temperature, cooling it after curing, if heated it becomes molten state again, and again in plastic molding. Therefore, the thermoplastic plastic melt repeatedly by heating curing, Thermo-plastic plastic waste can often be recycled so, that is, a so-called "secondary". In contrast, thermoset plastic is heated to a certain temperature curing, even continuing heated cannot change its status. Therefore, the thermosetting plastics cannot repeatedly by reheating, thermosetting plastic waste is often not recycled.

II, plastic by application of range also may is divided into general plastic, and engineering plastic, and special plastic; General plastic common of has: PP, and PVC, and PE, and PS, and,; engineering plastic common of has: ABS, and PC, and PMMA, and POM, and PA6, and PA66, and PET, and PBT, and SAN,; special plastic common of has: PPS, and PEI,; engineering plastic often by some general plastic modified sexual are; as changed some molecular structure, and added other components as glass fiber,Project is to be used as industrial parts or shell material of plastic for industrial use, its strength, impact resistance, heat resistance, hardness and resistance to aging of plastic.

Its features include: a, thermal properties of glass transition temperature (Tg) and melting point (Tm) and high heat distortion temperature (HDT) high, the long-term use of high temperature (UL-746B), using small temperature range, thermal expansion coefficient.

B, mechanical properties: high strength, modulus, low latent degeneration, high mechanical resistance to wear and fatigue.

C other:, excellent chemical resistance, fire resistance, electric resistance, dimensional stability and excellent weather resistance.

Practical application of the common plastic materials 1, ABS material: most commonly used plastic material, many household electrical appliances shell are made of it. With high mechanical strength, heat resistance, chemical resistance and high gloss. Common are Taiwan Chi Mei, and country Joe of ABS. Chimei: ABS PA757 general purpose grade, good gloss; ABS PA727 plating grade ABS PA777D heat resistance level.ABS usually heat denaturation temperature of not more than 88 degrees centigrade.

3, nylon PA6, PA66. Polyamide (Nylon) maximum advantage of toughness, excellent fatigue resistance, low coefficient of friction. Often used to make fibers, toothbrush, shredded fish, bushings, packaging film, gears, electric tools, shell, electrical parts, and so on. But the biggest drawback is absorbent, absorbent falling sharply increase its tensile strength. Such as adding a glass fibre can greatly improve its heat-resistance, that is, PA66+GF15%, PA66+GF30% temperature resistance up to 180~210℃. Therefore, there is no plus glass fiber nylon shall not be used for parts with high temperature requirements.

Plastic beer come out as soon as possible after use to avoid placing takes too long to make adverse changes have taken place after water absorption nylon.

biColor mold

biColor mold

A. bicolor forming principle

Two-color injection molding generally refers to two colors or different kinds of plastic molding, since the twotwo - color injection machine and the nozzle unit is separate and distinct, and therefore the color of the finished product is mostly clear two - color is not mixed together. Mold can be two different two - color characteristics of the resin and color, into a single color products, can reduce the molded product group legislature and post-treatment works. Save the cost of printing dissolved, increase the aesthetic visual effect of the product, enhance the added value of products. Not only have non-slip, increasing the friction function, flexible resin material to make it more ergonomic.

two - color injection molding machine and the general standard injection molding machine What is the difference?

two - color machine with the biggest difference lies in the general injection molding machine injection unit machine activity template design. In general, two-color machine has two independent separate injection unit, generally only one set of injection molding machine injection unit. Two configurations of the two injection units with the manufacturers of the design in many forms, as the activity template design is rotating mechanism must be provided, the general common design such as increasing the dial or shaft mechanism, so as to provide 180 ° reciprocating rotation, so that the mold to produce cyclic alternating movement. Another mold you do not need some special two - color wheel or shaft mechanism, but by mold or horizontal sliding alternately rotate.

B. Introduction bicolor mold

In the form of two - color mode

1. The two-color mode: two on the same plastic material injection molding machine, a two-molding, but the product is only the first mold. Usually this

Kinds of double injection molding process is also called, is usually done by a set of molds, and the need for specialized color injection molding machine. Which is divided into two 1-1. Carousel (rotary die holder) This mold has two male two female mold mold design time and points a shot and the secondary injection, usually once a feeding tube exit is on the left, two second injection on the right tube.

1-2 rotating plate like this mold structure focused above two male mold and two master mold, the difference is only in the rotation with the top two male mold base, and the rotation axis of rotation of the board is to use the board (male template) male die holder does not rotate, so the board shall be designed rotating shaft structure designed in the heart

2. overmold: two plastic materials are not necessarily on the same injection molding machine, a two-molding; product from a mold in the mold removed

, Then put another set of molds for the second injection molding. So, in general this molding process is usually done by two sets of molds, without the need for a dedicated two - color injection molding machine. Injection mold with its monochromatic mold structure is the same, mainly by adjusting the injection parameters to control the flow rate of material species binding sites.

overmolding mould china

overmolding

" Povermolding " is actually a kind of secondary injection molding, products generally includes main body (hard plastic) parts and outsourcing (soft glue), in the mold manufacturing, manufacturing hard plastic main body first, hard plastic mould design program is designed according to the normal subject, outsourcing (soft glue) mold design to hard plastic products as a reference, need not put shrink again, after mold parts, with hard plastic on the main body, front mould have plastic bags shape is different, in Mr Production output hard plastic main body, and then put the hard plastic main body in the outsourcing mould, into the soft plastic injection molding production outsourcing

2. " overmolding " characteristics

1) calculate shrink when main hard plastic parts die design

2) "overmolding " usually has two independent sets of mould

3) soft package mold after the mold parts with hard plastic one to main body, to avoid a small amount of space, hard rubber for rubber and plastic parts to use subject to become a phantom

Note TPU material, the characteristics of itself is relatively easy to stick mold, product if you can do the sand sand as far as possible, so easy to release! Liquidity of TPU is slow, cooling cycle will be longer, as long as pay attention to some in the production process, also won't have much of a problem!

Composite auto parts china

Composite auto parts

Automotive plastic to improve car performance and lightweight appearance plays an increasingly important role requirements. Emphasis in the automotive lightweight when it comes in a plastic found in this area. Whether it is the body, interior and exterior parts and other places, you can find different kinds of plastics applications. As one of the world's largest carmaker, BMW (BMW) is also due to be a trend, use a lot of plastic. Currently, automotive plastics by ordinary decorative purposes, development to manufacture structural and functional components also rising, such as heat resistance, high strength and impact resistance is the most common requirements, methods are generally dealing using composite materials or plastic alloy

Parts on the car using composite materials primarily dashboard, door guard, inner fender cover, carpet, seats and parcel shelf boards, this form of parts used in addition to meet certain functions, but also make people feel comfortable beautiful, but because of the kind of material production process is simple, low cost, applicability and developed more rapidly, it will be the main direction of development in the future of automotive interior materials.

Automobile industry drives the mold production

Automobile industry drives the mold production

Auto mould is still the most widely DaiDongMian, the field of industry development is rapid, every car HuanXing need thousands of pair of mould, auto makers has formed with the closely matching mould enterprise development, research and debugging technology, production of strategic alliance. Cars are increasingly high strength plate in order to reduce weight, also for some ultra high strength plate hot forming and the corresponding hot forming mould has naturally become the development trend.

Mold to use plastic lighter will increase and the development of new materials, including all kinds of new plastic, modified plastic, metal, plastic, magnesium alloy, composite material, and so on, this requires a new forming technology, which also requires that have adapted to the new mold. According to network mold, China mold in the future in the market, the proportion of total plastic mold in the mold will gradually increase, its development speed will be higher than other mold.

"Mould to elegant, requires good appearance generous, internal defects, this would require careful, precision mould with high quality. At present, the refinement has a big gap, refinement is often ignored by some companies, the results fell short." Company, I think that the mold fast and efficient production, this mould enterprises try to shorten the mold production cycle, to mold the user mould as soon as possible, on the other hand is more important, the user can you provide a mold to production products more quickly and efficiently. Such as more than a multi-cavity mould production, laminated mold, forming time and make good use of hot runner technology to shorten the use of multilayer composite technology, mould decoration technology, highlights non-mark injection molding technology, testing technology and process of composite technology and transfer technology and so on, at the same time stamping forming process intelligent also requires intelligent mold to adapt.
