What Is Injection Molding?


Injection molding(also called plastic injection molding) is a manufacturing process start from 1940s. The advantages of injection molding are fast production speed, high efficiency, automatic operation, various designs, shapes from simple to complex, sizes from large to small, and accurate product dimensions. Widely used in daily necessities, consumer electronics, automotive industry, and aerospace, etc.

At ZH, we provide injection molding service from tools making to mass production including finishing service. We can produce 20 to 10,000,00+ parts in all kinds of plastic material.

  • Outstanding Surface Quality

Usually, injection molded parts come out with very smooth surface.

The Injection Molding Process

After receiving the customer’s design and product drawing, we will make a DFM analysis report to discuss with the customer;

With confirming, we start to order the mold material-order the mold embryo-order the hot runner-print out the injection mold drawing;

The customer prepays 50% of the mold payment, and receives After the payment is received, the mold is first processed by programming a machining program, removing copper, and producing CNC and EMD processing drawings) and then processing.
