Injection molding is a molding technology widely used in industrial production, which can quickly produce various complex plastic products. In the injection molding process, the injection bottom is an important part, generally divided into metal injection bottom and plastic injection bottom. So, what is the material of injection molding? This article will give you a detailed answer.

1. metal injection bottom

metal injection bottom is an injection mold bottom made of metal materials. Commonly used materials include aluminum alloys, copper alloys, magnesium alloys, and steel. The metal injection bottom has the following characteristics:

1. Stable structure: The metal injection bottom is sturdy and durable, stable in structure, and can withstand a lot of pressure and wear.

2. Good thermal conductivity: The metal injection bottom can quickly dissipate heat, which can speed up the speed and efficiency of injection molding.

3. Long life: The metal injection bottom has a long life and can usually be used for many years without serious damage.

4. higher cost: metal injection bottom relative to the plastic injection bottom cost is higher, need to consider the production cost.

2. plastic injection bottom

plastic injection bottom is an injection mold bottom made of plastic materials. Commonly used materials include PE, PP, ABS, PC, etc. Plastic injection bottom has the following characteristics:

1. Lightweight: plastic injection bottom light weight, easy to install and replace.

2. Low cost: Compared with the metal injection bottom, the plastic injection bottom has lower cost and has more advantages in production.

3. Poor thermal conductivity: plastic injection bottom thermal conductivity is poor, heat dissipation is slow, resulting in a longer molding time.

4. Not resistant to wear: The plastic injection bottom is easy to wear and has a relatively short life.

summary: injection molding is an important part of the injection molding process, the use of different materials will affect the production efficiency and product quality. The metal injection bottom has a stable structure and good durability, but the cost is high; the plastic injection bottom is lightweight and low in cost, but it is not wear-resistant and has poor heat dissipation. In actual production, the appropriate injection bottom material should be selected according to product characteristics and production costs to achieve the best results.
