Technical application of plastic molds

1. For example, in many fields such as household appliances, instruments and meters, construction equipment, automotive industry, and daily hardware, the proportion of plastic products is rapidly increasing. A well-designed plastic component can often replace multiple traditional metal components. The trend of plasticization of industrial and daily products is constantly increasing.
2. The general definition of mold: In industrial production, various press machines and specialized tools mounted on the press machines are used to produce parts or products of the desired shape from metal or non-metal materials through pressure. These specialized tools are collectively referred to as molds.
3. Injection molding process description: Mold is a tool for producing plastic products.
4. General classification of molds: can be divided into plastic molds and non plastic molds:
Non plastic molds include casting molds, forging molds, stamping molds, die-casting molds, etc.
A. Casting mold - faucet, pig iron platform
B. Forging die - car body
C. Stamping die - computer panel
D. Die casting mold - superalloys, cylinder block
⑵ Plastic molds are divided into:
A. Injection molding mold - TV casing, keyboard buttons (most commonly used)
B. Blow mold - beverage bottle
C. Compression molding mold - electric wood switch, scientific porcelain bowl and plate
D. Transfer molding mold - integrated circuit products
E. Extrusion molding mold - glue tube, plastic bag
F. Hot forming mold - transparent forming packaging shell
G. Rotating molding mold - Soft rubber doll toy
Injection molding is the most commonly used method in plastic processing. This method is applicable to all thermoplastic plastics and some thermosetting plastics, and the quantity of plastic products produced is unmatched by other molding methods. As one of the main tools for injection molding processing, injection molds have a high level of quality accuracy, manufacturing cycle, and production efficiency in the injection molding process, which directly affects the quality, output, cost, and product updates of the products, and also determines the reaction ability and speed of the enterprise in market competition.
