INJECTION MOLDING

We have been mass producing injection molded parts in an economical way by most advanced plastic injection molding machines for 27 years.

injection molding Service

We provide turnkey serviceS from mold design, mold making, plastic injection molding to 24/7 customer service.

Mold Design

Mold designers use CAD software to design the injection mold for the plastic products. They check the shrinkage rate, sizes and geometry of the injection molded parts.Rich experience in complex parting surface design.

Mold Making

Since 1998, our mold making machines have been producing components designed by mold designers, and workers assembly them together. The components are high precision steel parts made by most advanced CNC machines.Rich experience in big size mold tooling.

Injection Molding

Injection molding is processed on injection molding machines. The injection mold is mounted on the machines and molten plastic flow is injected into the mold cavity to form the plastic parts.Size tolerance is up to +/-0.01mm. Low appearance defect rate.

Injection Molding Finish

  Materials Color Description
Smooth ABS PC PE PP PMMA PS  ALL colors Polish the mold cavity to #1200 sand paper to make parts surface smooth.
Painting ABS PC PE PMMA PS  All colors Spray a layer of paints on the surface of the products to protect them and make them look better.
Silk Screen Most common plastic All colors Print the logo, words or patterns on the surface of the products by silk screen.
Plating ABS, PC All colors Electronical plating makes the product look shining. The shining layer is chrome.

Injection Molding VS Rapid Prototyping

Injection molding is used for large quantity production while rapid prototyping for low volume production.

  • Injection molding offers low unit price but high cost injection mold, rapid prototyping makes parts without mold.
  • Injection molding produces thousands of products in several days, more efficient than rapid prototyping.
  • We start injection molding after confirmation of final products and rapid prototyping at the stage of product design and development.
  • The strength of injection molded parts are higher than prototypes.
  • There will be gate residue, pin mark, parting line on the injection molded parts, and prototypes don’t have these.

Injection Molding FAQ

Injection molding is a process making large quantity of plastic products. The molten raw plastic material was injected into the injection mold cavity to form plastic parts. This process was executed on injection molding machines.

Our biggest injection molding machine tonnage is 1320 ton which is often used to make product with more than 1 meter long size.

There are two sections of injection molding cost. 

  • Injection mold cost, generally more than $1500, depend on the size and annual demand of the products.
  • Injection molding cost, about $0.1 per unit, depend on the size, material and quality requirement of the products.

The common materials are ABS, PC, PS, PE, PVC, PMMA, NYLON, POM. 

Depend on the ISO tolerance standard, and we could reach ±0.05mm tolerance.
