What will affect the production quality of liquid silicone injection molding machine?

1. Quality of raw materials

The production quality of LSR injection molding machine is first affected by the quality of raw materials. LSR is a special rubber material that needs to have certain elasticity, softness and heat resistance. If the quality of raw materials is not up to standard, such as inaccurate additive content, excessive impurities, etc., it will lead to the quality of the produced LSR products is unstable, and even cannot be used. Therefore, it is very important to choose high-quality silica gel raw materials.

2. injection molding temperature

LSR injection molding is by injecting molten silica gel into the molding mold, and then solidifying at a certain temperature. The temperature of injection molding has an important effect on the physical properties and surface quality of the product. If the temperature is too high, the LSR will overheat leading to bubbles, while the temperature is too low, it is difficult to completely fill the mold pores. Therefore, controlling the injection molding temperature is an important factor to ensure the production quality.

3. Injection speed and pressure

Injection speed and pressure are also important factors in determining the quality of LSR injection molding products. Too fast injection speed will lead to LSR can not be fully filled in the injection process, and the injection speed is too slow, it is easy to cause product surface defects, such as sintering lines. Too high injection pressure will cause excessive stress in the LSR mold filling process, resulting in product deformation. Therefore, reasonable control of injection speed and pressure is an important measure to ensure the quality of LSR injection molding.

4.mold design and processing accuracy

Mold is the key equipment of LSR injection molding, mold design and processing accuracy directly affect the dimensional accuracy and surface quality of the product. The mold design should be reasonable to ensure that the LSR mold is evenly filled to avoid bubbles and defects. The mold processing accuracy should meet certain requirements to ensure the stability of product size and the perfection of product appearance. Therefore, in the process of LSR injection molding, the mold should be monitored and maintained to ensure its good condition.

5. Operation technology and experience

Operation technology and experience are one of the important factors affecting the production quality of LSR injection molding machine. Operators need to master the operating procedures and technical essentials of the LSR injection molding machine, and adjust and control the parameters of the machine. At the same time, the operator should have a certain amount of experience in the production of LSR injection molding machine, and have certain insights and solutions for the treatment of various problems. Only after systematic training and practice, can we ensure the production quality of LSR injection molding machine.
