China Plastic Injection Molding Manufacturing


Injection molding is defined as the common manufacturing process adopted for fabricating plastic parts for a wide range of products. This method is used to manufacture parts which differ in size, application and complexity and the process involves the use of a machine called an injection molding machine along with a mold and raw plastic. The process involves the melting of plastic in the molding machine along with injecting it into the mold from where it is cooled and solidified into the final product.


The advantages of using a China manufacturer is that there are more financial savings in comparison with the western plastic injection or production. The cost savings involved in mold construction is around 30% to 50% when compared with U.S. mold makers. Another advantage of them is the fast design production along with extremely quick delivery of first samples of plastic products.

There are other advantages like creating larger capacities and the possibility of cheap finishing of products like silk screen, sublimation techniques, tampo printing, stamp printing etc. It is also economical and has fast options of manual assembly. It offers various packaging options such as cardboard boxes, blistering or products which are sourced from different companies.

Other major advantages include the availability of complex parts and their structures, high efficiency along with easy and simple mass production of plastic parts, flexibility in terms of materials as well as colors and easy engineering of the molding process. This is also the most cost effective way for obtaining plastic products as the cost of resin and the process of manufacturing is much less when compared to metal machining and other molding processes.

SERVICES OFFERRED PET injection molding machine 

China manufacturers also offer services like advising on rapid prototyping or making of prototypes. They also have experience in fields like rubber and TPR/ TPE or TPO products. They are knowledgeable in the field of plastic products engineering and other materials along with high experience in two component injection moldings of plastic.

Most manufacturers also involve 3D CAD Design along with engineering and product development of the idea from its originality. They also incorporate rapid prototyping with the help of CNC milling from POM, PA, ABS or other varieties of plastics available. Molds are usually finished within 20 to 25 days and the prices of plastic molds range from $1500 to $3500.


There are six major steps involved in the mold making which are mold installation, material baking, mold clamping, material injection, cooling and solidifying of parts and ejection out.

Most manufacturers also ensure quality control of the products produced by plastic injection molding by inspection and analysis procedures along with complete dimension inspection of all the plastic mold components and the report is sent to the client for reviewing. The plastic injection molding machines ensure that each plastic mold is of top notch quality and is thoroughly inspected for defects in terms of visual, dimensional and functional aspects before shipping the plastic products to the clients around the world.
