 Description of products: these are clear products for news medicine and machine, transparent cover  and
supporter , these clear  parts are used on American, Europe, Canada,Australia industrial, we make the mould
in our mould manufacturer factory then test it in our china plastic injection molding factory


Plastic Injection molding China is considered one of the most common plastic part manufacturing
processes.It can be used for producing parts from both thermoplastic and thermoset polymers. The process
usually begins  with taking the polymers in the form of pellets or granules and heating them to the molten state.
The melt is then injected/forced into a chamber formed by a split-die mold. The melt remains in the mold and is
either chilled down to solidify (thermoplastics) or heated up to cure (thermosets). The mold is then opened and
the part is ejected.


A Typical Plastic Injection Molding Process
In spite of the relatively expensive tooling cost, injection molding remains the most popular manufacturing process
for plastic materials in mass production, thanks to its low operational cost, high throughput, and the flexibility to make parts with complex shapes.
Polymers commonly used for injection molding include

  • Polystyrene (PS)
  • Acrylonitrile Butadiene Styrene (ABS)
  • Polyamide (PA)
  • Polypropylene (PP)
  • Polyethylene (PE)
  • Polyvinylchloride (PVC)
Other short fiber reinforced plastics

General injection molding china  plastics making process

Plastic Injection molding china  is used to produce thin-walled plastic parts for a wide variety of applications,
one of the most 
common being plastic housings. Plastic housing is a thin-walled enclosure, often requiring
many ribs and bosses on 
the interior. These housings are used in a variety of products including household
appliances,consumer 
electronics, power tools, and as automotive dashboards.Other common thin-walled
products include different types of 
open containers, such as buckets. Plastic Injection molding china is
also used to produce several everyday items such as toothbrushes 
or small plastic toys. Many medical devices,
including valves and syringes, are manufactured using
plastic injection molding china as well.

The characteristics of precision injection molding


The characteristics of precision injection molding is: the size of the injection molded parts with high precision, small tolerance. To achieve the requirements of precision injection conditions must be met:

(1) the mold material is better, rigid, cavity dimension precision and template between positioning accuracy is higher, lower surface roughness.

(2) to adopt precision injection molding machine.

(3) to adopt precision molding process.

(4) to choose suitable for precision injection molding process of the material. Commonly used precision injection molding materials have several: POM, POM = CF (carbon fiber), PNM = GF (glass fiber), PA \ FRPA66 (enhanced PA), PC, etc.
 
Precision injection process can ensure the size precision injection molding is the important way to control the shrinkage of injection molded parts, including: thermal contraction, disguised contraction of molded parts, orientation and compressed contraction and elastic recovery.
