Converting Injection Speed…

This is a good starting point, but the most important factor is to know the 1st Stage Fill Time and 1st Stage Short Shot Weight. If these are matched, then the outputs match which is critical. Question: Say i have a process with .94sec fill time and 36mm screw. When i change to a 50mm screw, […]

Correcting Tiger Striping…

When these are in the mold surface, small changes such as reduced melt temperature, slower injection speed, and reduced packing pressure tend to help. These reduce the polymer’s ability to duplicate the cavity detail will improve the overall appearance, but do not fix the underlying problems.  Question: Are Tiger Stripes Solvable? All the processing changes […]
