비즈니스에 사출 성형을 선택하면 얻을 수 있는 많은 이점

What is injection molding?
Plastic injection molding is the process of melting plastic pellets (thermoset/thermoplastic polymers), once sufficiently malleable, injecting them under pressure into a mold cavity, filling and curing to produce the final product.

How does 플라스틱 사출 성형 work?
열가소성 사출 성형 공정은 알루미늄 몰드와 관련된 표준 공정입니다.알루미늄은 강철보다 열을 더 효율적으로 전달하므로 냉각 채널이 필요하지 않습니다. 즉, 절약한 냉각 시간을 사용하여 충전 압력, 외관 문제를 모니터링하고 고품질 부품을 생산할 수 있습니다.

Injection molds generally work at 150-200 degrees Celsius. In mass production, injection molds are subjected to high temperatures and pressures. In order to meet the processing needs of different injection molds, appropriate materials should be selected according to the product. The basic properties of mold steel are as follows:

1. Surface hardness and wear resistance.
The hardness of the plastic mold is around 50-60HRC, and the heat-treated mold material can provide sufficient hardness. During the molding process, the injection mold needs to be continuously compressed, which requires the mold to maintain good precision and stability during mass production.

2. Cutting performance
EDM and cutting operations are essential in the manufacture of injection molds. In order to improve the cutting performance and the finish of the mold material, the hardness of the raw material should be moderate.

3. Polishing performance
For plastic products with high surface requirements, the roughness of the cavity surface should be small. Therefore, for high-quality products, the choice of die steel should be a material with better polishing performance.

4. Thermal stability
The shape of plastic products is complex, and the mold cavity is difficult to process after quenching, so mold steel with good thermal stability should be selected. The heat-treated material is less affected by temperature and has good dimensional stability, which can ensure the dimensional accuracy and surface roughness requirements of the mold.
