Many of us in the manufacturing world know all too well – those pesky burrs and flash on plastic parts. They are like little manufacturing gremlins, popping up and causing all sorts of headaches. But don’t worry, we are here to solve the problem and find quick and effective solutions.

Today I would like to tell you why flash/burrs appear on plastic samples and how to improve mold problems.

Flash and burr mainly appear on the contact surface. When the melt passes through the space between the movable and fixed molds, the sliding part of the slider, and the gap of the insert and ejector, etc., excessive flash or burr is formed on the molded product. Such flash or burr acts as a lever during the injection molding process to nepal number data further increase the flash or burr, resulting in a local depression on the mold, causing the flash or burr to enter into a vicious circle. Therefore, if the flash or burr is detected at the very beginning, the mold should be modified as early as possible.



1. What causes flash defects in die casting and how to fix them?
1.1 Old form
An old mold can cause flashing on the surface of the plastic part. It does not fit tightly, and the plastic leaks out due to this looseness. Problems with an old or worn mold can be solved by repairing or redesigning the mold.

1.2 Incorrect balance of flow and pressure in the mold
Pressure, temperature and flow are some common causes of flash. The pack will not be uniform if the cavity filling is uneven.
