Causes:
- Designing the entrance of the path plastic flow ly.Cac meet.
The atmosphere is no place to escape.
- The impact of color, the position weldline usually affects the mechanical properties. Fix: Check the exhaust system of mold or adding gas drainage. -Can be designed to take the road to the location weldline invisible and non-structural (improving the flow, flow restriction), testing design review, if necessary, expand stem injection, avoid changing thickness of the sudden and complete heterogeneous mold. - Use materials with lower viscosity.
