The annealing treatment of plastic molds is mainly to eliminate the internal stress caused by various reasons, so that the quality of the parts meets the use standards, there are no obvious defects in the appearance, and the performance of the mold steel is improved to facilitate the subsequent processing procedures. Annealing can make the metal structure inside the mold more stable and balanced, ensuring the quality of subsequent processing and final heat treatment. Annealing is the pearlite in the mold metal.
Cracking in drawn parts can lead to high scrap rates. Discover the expert strategies to solve injection mold cracking through material handling, mold design adjustments, and process recalibration.
After the plastic mold is manufactured, it needs to be debugged and inspected. Only when it is confirmed that there are no problems can it be applied to mass production. Whether it is mold debugging or formal production, the mold must be controlled to ensure the normal production and mold quality. So what are the key points of mold control? The quality of plastic parts needs to be controlled, mainly divided into size and environment
