In manufacturing, Die-casting machine And injection molding machines are common plastic molding equipment, but there are obvious differences in their working principles and applications. This article will introduce the difference between die-casting machine and injection molding machine to help readers better understand their characteristics and uses.

1. Operating principle:

 ● Injection molding machine: The injection molding machine injects molten plastic materials into the mold, and then cools and solidifies to form plastic products. It uses the method of heating the plastic material to the molten state, and then injecting it into the mold under high pressure.

 ● Die casting machine: The die casting machine cools and solidifies the molten metal material by injecting it into the mold and then applying high pressure. It uses the method of heating the metal material to the molten state, and then injecting it into the mold at high pressure.

2. Applied materials:

● Injection molding machine: injection molding machine is mainly used to process plastic materials, such as polypropylene, polyethylene, polystyrene, etc. Plastic materials can be dyed and added with specific additives as required.

● Die casting machine: Die casting machine is mainly used for processing metal materials, such as aluminum alloy, zinc alloy, magnesium alloy, etc. The selection of metal materials can be adjusted according to product requirements and application fields.

3. Equipment structure:

● Injection molding machine: injection molding machine is usually composed of injection section, curing section, cooling system, control system, etc. They have different working units to realize various stages of plastic molding.

● Die-casting machine: die-casting machine is usually composed of metal furnace, injection system, mold system, cooling system, die-casting mechanism, control system, etc. They work together to realize the process of metal melting, injection and molding.

4. Product features:

● Injection molding machine: injection molding machine can produce complex plastic products with good surface quality and dimensional stability. It is suitable for the production of large quantities of plastic products.

● Die-casting machine: die-casting machine can produce metal products with high precision and strength, which is suitable for industrial and automotive applications with strict requirements. It has unique advantages in manufacturing metal parts

To sum up, die-casting machine and injection molding machine There are obvious differences in working principle, applied materials, equipment structure and product characteristics. Understanding their differences will help to select appropriate molding equipment and better respond to different production needs. Both of these devices play an important role in the production of plastic products and metal products, and play an indispensable role in the manufacturing industry.
