How hard should the plastic mold be? Since the first attempt to exchange plastic mold design ideas, the storm in the teacup has been raging. For a molder, 48 Rockwell "C" is enough; for another 54 years old, and another one does not accept anything under 60 years old. In use, the mold hardness for economic operation is as low as... read more
An injection mold is a mold into which the plastic material is introduced from an external heating or plasticizing cylinder. This mold runs at a constant temperature; cool, or slightly warm. Injection molds are mainly used for thermoplastic materials, which are shaped as they cool. The main components are the cavity, the cavity fixing plate... read more
A logical and systematic method of handling failures is the most desirable, and many actual mold manufacturers have their own operating plans. When preparing such a plan, it is important to ensure that all terms used are clear and understood by all relevant personnel. The failure should be clearly described and all possible causes should be check... read more
Undoubtedly, mold maintenance actually originated from the design department, when the core features of the mold mechanism were worked out. Moreover, they in turn are reflected in the way of operation, wear and stress, and the complete ability of the tool to withstand the responsibilities it assumes. The mold designer can put in some con... read more
Mold opening direction and parting line At the beginning of the design of each injection product, the mold opening direction and parting line should be determined to minimize the core-pulling slider mechanism and eliminate the influence of the parting line on the appearance. 1. After the mold opening direction is determined, th... read more
