What is Plastic Injection Molding?

Plastic injection molding involves melting granular plastic pellets into a liquid form and then compressing this liquid into the empty cavity of a mold tool. The plastic will retain the shape of the mold as well as the surface texture of the walls of the cavity. After an optimized injection and cooling phase, the now solidified plastic part is ejected and the molding cycle is repeated. This molding cycle can take from as little as a few seconds to several minutes depending upon part size, molding resin and part design.

Wahi provides one-stop injection molding solution for Automotive, Home appliances, Portable video game devices, Smart phones and Medical equipments etc. Equipped with 21 sets injection machines such as JSW and FCS, we can meet customers mold testing and mass production requirements.

Our injection engineers apply Scientific Molding Process to testing each mold production with using below steps to qualification master injection parameters: 

1. Mechanical Test – verify mold functions properly

2. Viscosity Test – determine the most stable flow pattern, injection speed and fill time

3. Short shot balance Test – verify fill balance properly

4. Gate Seal Test – determine holding time parameters

5. Pressure Loss Test – verify runner & gate size properly
