What is Plastic Injection Molding?
Plastic injection molding is used to manufacture solid components. This process involves injecting molten plastic into a metal mold to produce plastic parts. This process can be traced to 1872 when John Wesley Hyatt, an American inventor, patented the first plastic injection molding machine.
The Status and Development Trend of Injection Molds
The plastics industry is one of the most dynamic industries today. Plastics are one of the main modern industrial structural materials, widely used in automobiles, aerospace, electronic communications, instrumentation, stationery and sports supplies, chemicals, textiles, medical and health, construction hardware, household appliances and other fields. By 2004, the annual output of plastic parts in China has exceeded 25 million tons. Looking forward to the 21st century, polymer synthetic materials will enter a period of qualitative leap development.
