1, such as: household appliances, instruments, construction equipment, automotive industry, daily-use hardware and many other fields, the proportion of plastic products is rapidly increasing. A reasonably designed plastic parts can often replace multiple traditional metal parts. The trend of plasticization of industrial products and daily-use products is rising.
2, the general definition of mold: in industrial production, with a variety of presses and special tools mounted on the press, through the pressure of metal or non-metallic materials to make parts or products of the required shape, this special tool is collectively known as the mold.
3、Injection molding process description: mold is a tool for producing plastic products.
4, the general classification of the mold: can be divided into plastic molds and non-plastic molds:
(1) non-plastic molds are: casting mold, forging mold, stamping mold, die-casting mold, etc.
A. Casting mold - faucet, pig iron platform
B. Forging mold - car body
C. Stamping mold - computer panel
D. Die-casting mold - super alloy, cylinder body
(2) Plastic mold according to the production process and production products are divided into:
A. injection molding mold - TV shell, keyboard buttons (the most common application)
B. Air blowing mold - beverage bottles
C. compression molding mold - bakelite switches, scientific porcelain dishes
D. Transfer molding die - integrated circuit products
E. Extrusion molding mold - glue tube, plastic bags
F. Thermoforming mold--transparent molding packaging shell
G. Rotational molding mold--soft rubber doll toys
Injection molding is the most common method used in plastic processing. The method is applicable to all thermoplastics and some thermosetting plastics, and the quantity of plastic products made is unparalleled by other molding methods. As one of the main tools of injection molding process, the injection mold, in terms of quality accuracy, manufacturing cycle and production efficiency in the injection molding process, directly affects the quality, output, cost and product renewal of products, and also determines the responsiveness and speed of enterprises in the market competition. It also determines the responsiveness and speed of the enterprise in the market competition.
