The various tools and products used in our daily production and life, ranging from the base of the machine tool, the body shell, to a cup-head screw, button and the shell of various household appliances, are all closely related to the mold. The shape of the mold determines the appearance of these products, and the processing quality and precision of the mold also determines the quality of these products.
So what is the definition of a mold? In industrial production, various presses and special tools mounted on the press are used to make metal or non-metallic materials into parts or products of the required shape through pressure. This special tool is collectively called Mold. General classification of molds: can be divided into plastic molds and non-plastic molds.
Non-plastic molds include:
1. Casting mold-faucet, pig iron platform, 2. Forging mold one-car body, 3. Stamping mold-computer panel, 4. Die casting mold super alloy, etc.
Plastic molds are divided into different production processes and products:
1. Injection molding mold-TV shell, keyboard buttons (the most common application). 2. Blowing Mould one-beverage bottle. 3. Compression molding mold-bakelite switch, scientific porcelain dishes. 4. Transfer molding mold one-integrated circuit products. 5. Extrusion mould-glue pipe, plastic bag. 6. Thermoforming mold one—transparent molded packaging shell. 7. Rotary forming mold one-soft rubber doll toy.
In recent years, with the rapid development of the plastics industry and the continuous improvement of the strength and precision of general and engineering plastics, the application range of plastic products is also expanding, such as: household appliances, instrumentation, construction equipment, automobile industry, Japan In many fields such as hardware, the proportion of plastic products is increasing rapidly. A reasonably designed plastic part can often replace multiple traditional metal parts. The trend of plasticization of industrial products and daily-use products is on the rise. Among them, injection molding is the most commonly used method in plastic processing. This method is suitable for all thermoplastics and some thermosetting plastics, and the number of plastic products produced is beyond the reach of other molding methods.
