about plastic injection mold

 It is mainly the production of thermoplastic products the most common kind of mold, plastic injection mold processing equipment for the plastics injection molding machine, plastic melt first heat in the heated barrel of the end of the injection machine, and then injection molding machine into the mold cavity under the impetus of a screw or a plunger, the injection machine nozzle and mold casting system, plastic cooling hardening molding, mold release to get the products. Its structure is usually molded parts, casting systems, parts-oriented components, the introduction of institutions, thermostat systems, exhaust systems, and support components. Manufacturing materials commonly used plastic mold steel modules, commonly used material is mainly carbon structural steel, carbon tool steel, alloy tool steel, high-speed steel. Injection molding process usually applies only to the varieties of products, production of thermoplastic injection molding process to produce plastic products is very extensive, from the daily necessities of life to all kinds of complex mechanical, electrical, transport parts are injection molding, it is the most widely used in the production of plastics processing methods.

Interior and exterior the car accessories use plastic type

Interior and exterior the car accessories use plastic type:

plastic injection mold  auto accessories

General plastic on one car weight approximately 10% per cent of total vehicle weight. Which amount is the largest automotive polymer materials PP, representing about plastics for automobile by about 20% of the total. Plastics in the automotive industry occupies a pivotal position. The following are typical cases of application of plastics in the automotive industry:

 

Main varieties are for automotive plastics: PP, PU, styrene class (ABS,PS,SAN,SMA), PVC, PE etc. Polypropylene PP Max, very wide range of applications, representing about plastics for automobile by about 20% of the total. Its mainly because of lower production costs, while providing good processing properties.

For door assemblies, column cover, cockpit module threshold bumper moulding strip side guard, PP in a large number of applications in the automotive interior and exterior decoration, such as cockpit module, gate guard, bumper, and so on. Styrene-butadiene-acrylonitrile or ABS: application is more extensive, frequently used is ABS and its alloys, such as PC/ABS, and PVC/ABS.

Inside and outside the ABS in cars decorated with a wide range of applications, such as dashboards, barrier, lighting systems, wheel covers, door handles and other PC/ABS is often used as its alloy plating. Pu PU: polyurethane foams in car soft decoration has a irreplaceable status in plastic products, such as soft decoration dashboard, seats, door systems.

Application of polyurethane in automobile decorations interior and exterior: soft foam: semi-rigid foam cushion, backrest: dashboards, handrails, head of hard foam: roof lining elastic RIM: bumper. Polyamide (nylon) PA: polyamide types there are many, often used in automobiles are PA6 and PA66. For example, wheel covers, bumpers, intake manifold, pedal type, rear-view mirror.

And so on. Polycarbonate PC: Polycarbonate with excellent performance, high transparent, so is widely used in vehicle lighting systems.

Polycarbonate alloy, such as PC/ABS, PC/PBT inside and outside the vehicle bumpers made of ornaments is often used in PC/PBT often used in the premium-car.

These plastic types, we are a skilled application experience. But also all kinds of special plastics, PPT,PEI,PEEK,POM, and so on.

At the same time in medical devices, plastic products for life, and defense industry are involved.

hot runner

热流道模具：

热流道（hot runner）是在注塑模具中使用的，将融化的塑料注入到模具的空腔中的加热组件集合。而热流道模具是利用加热装置使流道内熔体始终不凝固的模具。因为它比传统模具成形周期短，而且更节约原料，所以热流道模具在当今世界各工业发达国家和地区均得到极为广泛的应用。

一般来说，热流道系统分为单头热流道系统，多头热流道系统以及阀浇口热流道系统。由热喷嘴，分流板，温控箱和附件等几部分组成。

因为热流道模具没有浇道系统冷却时间的限制，制作成型固化后便可即时订出。许多用热流道模具生产的薄壁零件成型周期可以在5秒以下。并且具有节省塑料预料，减少废品率，提高产品质量，消除后续工序，有利于生产自动化等优点。在世界上工业较为发达的国家和地区热流道模具生产极为活跃，热流道模具的生产比例不断提高。中国的热流到尚处于起步阶段，但是正在快速增长，模具质量显著提高。

我们是专业注塑模具生产商，由丰富的热流道模具制作经验，公司主要使用的热流道品牌有柳道（韩国），先锐（韩国），DME(美国）、INCOE（美国）、MOLD-MASTER(加拿大---热流道的老大）、HUSKY(加拿大)、SM（塑美-中国）等。更多信息请参阅plastic injection mold 或者plastic products希望能为您提供一些帮助！

Hot runner mold

Hot runner is used in the injection mold, melted plastics injected into the mold cavity heated component in the collection. Hot runner mold is the use of heating devices so that the manifold is always the solidification of the melt mold. Because it is shorter than the traditional mould forming period, but also saves raw materials, therefore hot runner mold in today's industrialized countries and regions of the world have been extremely wide range of applications.

In General, hot runner system of hot runner system into a single, long hot runner system and valve gate hot runner system. From the hot nozzle, manifold, temperature-controlled boxes and accessories consists of.

Because the hot runner mold not runner system cooling time restrictions, makes curing immediately after setting out. Many hot runner mold production of thin-walled parts the cycle time can be 5 seconds. And economical plastic is expected to reduce reject rate, improve product quality, eliminate the follow-up process, in favour of production automation and so on. Industry in the world more developed countries and regions of hot runner mold production is extremely active, hot runner mold production ratio continues to increase. Heat flow to China is still in its infancy, but is growing rapidly, significantly improve the quality of the die.

We are professional manufacturer of plastic injection mould, by the rich experience in the hot runner mold make, the company uses hot runner brand Liu Dao (Korea), sharp (Korea), DME (United States), INCOE (United States), MOLD-MASTER (Canada---runner boss), HUSKY (Canada), SM (plastic-US-China).

目前我国模具产业发展现状，塑料和橡胶制品不仅被广泛用在汽车，机械电子，石油化工，轻工等国家支柱产业，而且在国防，航空，航天等国家战略领域占有重要地位。2008年我国塑胶制品行业规模以上企业完成产量3302万吨，居世界第二位。规模以上企业完成总产值8018亿。不过其中存在中低档产品偏多，高档精密产品少；通用技术产品多，高科技，高附加值产品少等问题。

模具行业发展遭遇了前所未有的困难

塑料制品主要依靠模具加工成型。模具设计与制造水平直接关系到塑料制品的质量，质感，应用范围以及更新换代速度，是制约我国塑料制品升级改革，代替进口和打入国际市场的“瓶颈”，也是我国制造业现代化发展的关键。我国模具行业近年来发展迅速，模具总产量位居世界第三。但是高档塑料模具以及高附加值的橡塑制品还主要依赖进口！

我们从事注塑模具十余年，专业从事精密注塑模具制造和精密注塑成型，模具精度≤0.03MM。是伴随中国模具行业发展的代表企业，是中国精密模具的的领跑者！更多资讯请参阅injection mold china  plastic injection molding factory

The current developing situation of Chinese mold industry, plastic and rubber products are widely used not only in the automobile, machinery and electronics, petrochemicals, light industry, national pillar industry, but also in national defense, aviation, aerospace and other national strategy has an important place in the field. In 2008 China's output of plastic products industry enterprises above the designated size 33.02 million tons, ranking second in the world. Gross output value of enterprises above designated size 801.8 billion. But there is low to medium range products on the high side, high-grade precision products and little general technical products, high tech, higher value-added products less, and so on.

Mold industry has suffered unprecedented difficulties of plastic products rely primarily on mould processing takes shape.

 Die design and manufacture level directly related to the quality of plastic products, texture, range of application and the renewal rate, is restricting the upgrading reform of plastic products in China, instead of importing and to enter the international market, "bottleneck", is also key to modern development of Chinese manufacturing industry. China's mould industry developed rapidly in recent years, mold production ranked third. But high-grade plastic mold and rubber and plastic products also rely mainly on the import of high added value! We injection mould more than 10 years specializes in precision injection mould manufacturing and precision injection molding mould accuracy ≤ 0.03MM. Accompanying China mould industry representatives in the development of enterprises, is the leader in precision mold! For more information, see injection mold  www.injectionmodchina.com
