Precision mechanical parts processing, not any material can be precision processing, some materials hardness is too large, across the hardness of the machine parts, may break the machine parts, so these materials are not suitable for precision machining, unless it is made of special materials, or laser cutting. So what are the material requirements for…
1, plastic mold working conditions Due to the development of plastics and plastic molding industry, the quality requirements of plastic molds are getting higher and higher, so the failure of plastic molds and their factors have become an important research topic. The main working parts of plastic molds are molded parts, such as convex molds,…
The injection molding process can be roughly divided into the following six stages: Close mold, shot glue, pressure protection, cooling, open mold, product removal. The above-mentioned process repeatedly, can be batch periodic products. The molding of thermosoplastics and rubber also includes the same process, but the barrel temperature is lower than thermoplastic plastic, injection pressure…
