Plastic manufacturing Services


China Earnest Company provided high quality plastic manufacturing services.

We have a fully integrated manufacturing facility for the manufacture of plastic parts for the electronic housings,outdoor soprts equipemnt,furniture,Auto parts and Medical device industries.  The manufacturing services include CNC machining,Injection mold, Extrusion die,packaging and assembly.

Getting the idea designed, prototyped, engineered as well as the manufacturers tooling costs and other items all add up. Whilst we focus on keeping these costs low,and provide design suggestion to reduce the production cost in maximal degree.


The plastic material we use include:




Here are the production flow for your custom products:



China Earnest provides high quality prototype manufacturing services that are perfect to turn your design to real product.

Prototyping is an necessary part to verify if the concept design is correct before proceeding to manufacture and a working prototype of your design is a better chance to show your potential investors.But how to choose a process method to get a prototype?there are some type of prototypes from different technology, including CNC milling, 3D printing and vacuum casting. Which one is right for your prototype will depend on your end goal for the product idea .


How to choose a best process method for your plastic prototype


CNC machining/Turning

--Functional verification requirements


There are many advantages to use CNC Machining.

If you want to verify the function of the product as well as the surface effect, CNC machining and turning for rapid prototype is better optional.

Because it ensure the requirements of the product sizes,function and the material will be consistent with the batch production.



--Structural verification requirements

This prototype from 3D printing can’t be exactly same as the final mass production of the product, but it can make sure the product size and structure,Also will provide a shorter lead time and more favorable cost.



Vacuum Casting

--Silicone rubber prototype.

If you choose the material is silicone rubber, Vacuum castingcan fulfill the requirement.


2.Mass production for plastic products


Plastic injection molding

What is injection moulding and how does injection moulding work?

Injection molding and extrusion production is one of the main processes in the production of plastic products. This is a fast process for producing a large number of identical items from high-precision engineering parts to one-time consumer goods.

Most thermoplastics can be processed by injection moulding; the most common materials used include:

· Acrylonitrile-Butadiene-Styrene ABS

· Nylon PA

· Polycarbonate PC

· Polypropylene PP

Plastic injection molding can meet the needs of large volume and minimize unit cost,China Earnesst offer mold design service and product design suggestions in mass production,so that it can reduce a lot of production cost and get high quality plastic parts.



Plastic Extrusion Die


The objective of an extrusion die is to distribute the polymer melt in the flow channel such that the material exits from the die with a uniform velocity.

We Specializing in the production of various types of plastic extrusion products, including PVC, PP, PE, PS ,ABS,TPU,TPE,TPR,PMMA,PC and other engineering plastics, According to customer requirements to develop a variety of mold,specializing in the production of plastic extrusion profiles,lampshade,bracket,and other products. Products are widely used in furniture, kitchen cabinets, interior decoration, lighting, photo frames, cars, electronics and so on.
