The main properties of plastic products

Plastics is made from plastic as main raw materials processing of living supplies, industrial supplies.

Compared with other materials, plastic has the performance characteristics of the following aspects:

1. Light weight plastic is lighter material, relative density distribution is between 0.90 2.2. Obviously, the plastic can float to the surface of the water? Foamed plastics, in particular, because there a microporous, quality of a material is lighter, relative density 0.01. This makes the plastic can be used to reduce the weight of the product production.

2. Excellent chemical stability The vast majority of plastic of acid, alkali and other chemicals have good corrosion resistance. Especially commonly known as king plastic for ptfe (F4), its chemical stability is better than gold, even in the "aqua regia" boiled over ten hours also can't bad. Because the F4 has excellent chemical stability, is the ideal of corrosion resistant material. Such as F4 transport corrosive and viscous liquid can be used as the material.

3. The excellent electrical insulation properties Common plastic is a poor conductor of electricity, its surface resistance and volume resistance is very big, with Numbers of up to 109 a 1018 ohms. The breakdown voltage, dielectric loss Angle tangent value is very small. As a result, the plastic in the electronic industry and mechanical industry has been widely used. Such as plastic insulated control cables.

4. A poor conductor of heat, with noise elimination and damping effect Generally speaking, the thermal conductivity of the plastic is relatively low, quite steel 1/75-1/225, the microporous foam contains gas, its better heat insulation, sound insulation, shockproof sex. Such as polyvinyl chloride (PVC) thermal conductivity was only about 1/357 of the steel, aluminum 1/1250. On insulating ability, single glass window plastic is 40% higher than the single glass window aluminum, 50% higher than double glass. Will be combined with hollow glass, plastic form used in residential, office, room, hotel, save central heating in the winter and summer air conditioning saving costs, benefits obviously.

5. Wide distribution and high mechanical strength than strength Some plastic as hard as a stone, steel, and some soft such as paper, leather; From the plastic hardness, tensile strength, elongation and impact strength mechanical properties, such as wide distribution, there is a lot of use of choice. Because of the proportion of plastic small, strength, and thus has high specific strength. Compared with other materials, plastic also exists obvious shortcoming, such as easy burning, high stiffness than metal, aging resistance is poor, no heat, etc.

   Characteristics of plastics

  The plastic is a synthetic resin (polymeric resin or a condensation resin) as a main component, and the mixture is added according to the different needs of the different additives consisting of, has unique properties:

   • density: 100Kg per plastic can substitute other materials 200 ~ 300Kg, can reduce vehicle weight and increase payload.

   • good physical properties: good flexibility, wear-resistant, shock absorbers, plastic unit mass impact resistance not inferior metals, some plastics, carbon fiber reinforced plastics, etc. are also much higher than the metal.

   • Chemical resistance: Plastic acid, alkali, salt and other chemicals are resistant to corrosion, which is the most stable chemical properties of PTFE material; most commonly used corrosion-resistant materials, hard PVC, it concentration of 90% can be resistant to concentrated sulfuric acid, hydrochloric acid and various concentrations of lye.

• design flexibility: can be made transparent, translucent or opaque products, the appearance of a variety of surfaces can produce a distinctive pattern.

Plastic products can not only reduce the number of parts, reducing noise has also played a good role in automotive design and many conditions, in order to reduce weight and cost, greater use of plastic has important significance. Future trends in automotive materials transition from metal to plastic.

cnmoulding - IML technology introduction

The IML Chinese name: mould insert molding Its process is very significant features are: surface is a layer of hardening of the transparent thin film, the middle is printed pattern layer, the back is plastic layer, because the ink caught in the middle, can make the product to prevent surface is scratched and friction resistance, and can keep the color bright not easy fade for a long time.

The  IML technology introduction

Keywords: on IML IMD molding process

1. The concept of on IML

IMD (In Mold Decoration) is a kind is placed In the injection mould to decorate the plastic Film Film appearance on the surface of the new technology. IMD currently there are two kinds of methods, one kind is the printed Film roll Film made into circulation drum belt, installed in the injection molding machine and injection molds, like the tag Label on front mould surface automatic cycle produced with mobile; People call it the IMD (in mold transfer molding).

The other is a good Film Film printing machine after Forming Forming, again after shearing is placed in the injection mould. Is called on IML film (in the mould injection molding). The Film in general can be divided into three layers: base material (PET) normally, printing INK layer (INK), agglutination materials (as a special kind of glue).

When the injection is completed, through the role glue Film and plastic together together, because itself is surface of wear resistant protective Film PET in the outermost layer, have the effect of the wear resistance and scratch resistance, its surface hardness can be up to 3 h, and will feel more and more bright. The molding material, PBT, PC, PMMA, etc. The diagram below:

2, IML craft process

Cutting material - print - ink dry fixed - stick protective Film - flush positioning hole - thermoforming - cutting peripheral shape - material injection molding process is as follows: details are as follows: 1) cutting material: cut rolls of Film Film has good design size square piece, for printing, molding process.

2) print: according to the requirements of the ICONS and text made into a Film, on the square piece cut out good Film Film printing icon and text.

3) ink drying is fixed: square the printed Film Film placed in high temperature oven drying, purpose is fixed on IML ink.

4) stick protective Film: avoid rush in positioning hole process with flowers has printed Film Film surface, sometimes need to put a single or double protective Film.

5) blunt positioning hole: thermoforming positioning hole must be crossroads. The shear process sometimes prior to positioning hole punching.

6) thermoforming (high pressure or copper) : the printed film, after heating with high pressure machine or copper molding in preheating condition.

Shape: 7) shear periphery to forming good stereoscopic film scrap shear off.

8) material injection: after the molding and mold three-dimensional shape exactly the same as the film on the front mold, injection molding on IML products.

3，The advantages and disadvantages of IML process

Advantages:

1) the film production cycle is short, can perform multiple colour;

2) can change design and color in production;

3) is the outermost layers on IML FILM, screen printing ink, in the middle tier, and bright and clean appearance, more to touch the light, it has excellent resistance to scratch;

4) on IML production batch number is flexible, suitable for many kinds of small production

Disadvantages:

1) the early stage of the cycle is long;

2) easy to produce the film falls off, distortion, and so on and so forth;

3) the product defective rate is high.

Injection Molding Adapts to a More Interconnected World

Plastic, rubber, and metal injectionmolding and, more recently, rapid molding techniques have been major contributors in global manufacturing. A variety of processes and equipment can be used, depending on volumes, materials and turnaround time, and whether parts are prototypes or finished ones. The rise of rapid molding for fast delivery of high-mix, low-volume products and prototypes, and new ways to make molds such as 3D printing, are changing the way design engineers use injection molding in product development and production planning.

Droduct manager for the cnmould service of fast-turn molding company cnmoulding molding services can be classified into three different types: traditional high-volume molders; a broad group of lower-cost, high-volume molding services typically located offshore; and rapid molders, a more recent phenomenon.

Traditional molders are usually full-service suppliers. "They are all about injection molding tools that last forever, and about speeding up injection," he said. "They do a lot of value-add services like assembly or painting." Tooling used by these services tends to be made of hardened steel; hundreds of thousands to tens of millions of parts are made from multi-cavity production molds.

Rapid molding is newer, and something Proto Labs helped pioneer. It serves the need for making multiple variations of a single product in somewhat lower volumes -- 25 to 1,000 units instead of 100,000 or more, said Barsness. These products and all their components must be prototyped exactly, in all those variations, using exactly the materials they will be produced with.

The resulting increase in SKU proliferation is caused by several colliding trends. First, globalization has produced effects, as described by Barsness. "Say you make a household product or a communications device, and you want to sell it around the world," he said. "Your market used to be the US, but now there's the Chinese market and other countries, like Brazil. Customers in those countries have different values and tastes, whether it's a car or a thermostat." Those countries also have different regulations, such as those for safety, and different specifications, such as for electrical voltage, which effect part variations.

Trends related to energy and environmental friendliness are also driving changes in product designs. "Lightweighting is major, especially in anything that moves," said Barsness." Also, LEDs are being used everywhere for their ability to reduce the power, size, and cost of lighting, and they can be packaged almost any way imaginable. On many of these LED-enabled products, the entire assembly can include five to 10 different injection molded parts.

A third set of changes is due to increases in product connectivity and automation. The Internet of Things has engineers putting sensors on just about anything, from household appliances to industrial products. "Now the design engineer has to get 10 different prototypes of 10 different products for 10 different countries, all of them have LEDs, and they've all got to talk to the Internet," Barsness remarked. This is where rapid molding services come in.

Rapid molding tooling is typically "soft," represented by aluminum instead of steel, for a much lower cost. Rapid molding, of course, has a much faster turnaround. A traditional molder, using a high-volume production mold, could typically take a few months to deliver entire part runs, but the average rapid injection molder delivers parts in 25 to 45 days. Proto Labs' service promises one to 15 days.

Before rapid molding begins, prototypes are also made with production-grade materials. Typically, a customer sends three to five iterations of a design, and Proto Labs cuts a different mold each time. The industries Proto Labs serves tend to be those with some regulation or a high amount of product churn.
