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
