Troubleshooting Common Issues With Machine Injection Moulding
Troubleshooting common issues with machine injection moulding involves identifying and resolving problems such as sink marks, warping, air traps, and short shots. By thoroughly checking the material for contamination, adjusting mold temperature, setting appropriate vacuum, and inspecting for mold deflection, these issues can be effectively addressed. Common Issues With Plastic Machine Injection Moulding Common issues with plastic injection molding machines can include weld lines, sink marks, warping, air traps, and short shots. To troubleshoot these problems, it is important to thoroughly check the material used, adjust mold temperature, set appropriate vacuum, and check for mold deflection. Increasing pack and hold times and reducing injection speed can also help to address these issues. Weld Lines: Weld lines occur in plastic parts when two or more melt fronts come together and meet in the middle. These lines can weaken the structural integrity of the fin...
