1. What materials are used for injection molds?
1. Therefore, injection mold manufacturers recommend choosing tool steels with moderate quenching. Otherwise, the microstructure of the material and the size of the plastic mold will change. Most of the mold parts that are easy to process are made of metal materials, and some of them have complex structures and shapes.
2. Acrylic resin has high tensile strength, can withstand loads, will not absorb odors, and can maintain tight tolerances during injection molding. The material is also resistant to sunlight and weather, making it suitable for outdoor use.
3. The following are some of the plastic materials used in injection molding: Acrylic (PMMA) Acrylic, also known as plexiglass, is a hard transparent plastic material that is commonly used in electronics and automotive parts.
4. Traditional injection mold material steel: The injection mold is more widely used in high-quality cold work die steel, hot work die steel and alloy tool steel, which has the characteristics of high hardness, good processability, wear resistance and impact resistance, and is suitable for making molds for large quantities of products.
5. Generally speaking, the materials of injection molds can be divided into three categories: ordinary steel, alloy steel and special steel.
Ordinary steel refers to the steel with low carbon content in carbon steel and alloy steel, which is mainly characterized by low price and easy processing, but low hardness and strength, and insufficient wear resistance and corrosion resistance.
6. Chuangzhi plastic mold injection molding manufacturers five general plastics: PE (polyethylene): more common are used in bags, plastic basins, plastic buckets, etc. PVC (polyvinyl chloride): It is wires and cables, downpipes, conduits, electronic products, packaging materials, etc.
Second, what are the properties of commonly used plastic mold steel?
1. What are the commonly used plastic mold steels, and what are the properties, and what are the common steel productsPlastic mold C45W medium carbon steel American standard number: AISI1050~1055; Japanese standard number: S50C~S55C German standard serial number: 1730.
2. Plastic mold steel can generally be divided into six categories: age-hardening plastic mold steel (including mirror mold steel), corrosion-resistant plastic mold steel, carburizing plastic mold steel, pre-hardened embedded mold steel (including free-cutting steel), quenched and tempered plastic mold steel and hardened plastic mold steel. The performance requirements of plastic mold steel are strict, and heat treatment is difficult.
3. Corrosion-resistant steels include S136H and PAK90. Swedish imported company steel 718S and 718H pre-hardened plastic mold steel: good polishability, good wear resistance, high tensile strength. It is often used for internal mold inserts with high polish and high requirements. Suitable for plastic molds such as PA, POM, PS, PE, PP and ABS.
