How to choose the appropriate injection molding machine model?

The selection of injection molding machines is like choosing clothes that fit well, it depends on your product needs. Core parameters and adaptability are the key points:

1、 First, look at the product requirements

Locking force: calculated based on the projected area and material of the product (e.g. PE material Kp=0.32410cm ² requires approximately 131.2 tons).

Injection volume: the actual weight of the first mock examination product is recommended not to exceed 70% of the theoretical value.

Mold adaptation: The column spacing and mold opening stroke need to match the mold size.

2、 Parameter comparison and adaptation

Theoretical capacity: reflects the plastic processing capacity under ideal conditions.

Injection volume: The amount of plastic injected in one shot.

Pushing stroke and force: affect the demolding effect.

Screw diameter to aspect ratio: affects mixing uniformity and injection pressure.

3、 Practical model reference

BP-8180-A small injection molding machine for Baopin laboratory: suitable for sampling, with a clamping force of 250 tons and a temperature range of room temperature to 300 ℃.

Lijin 560 ton servo injection molding machine PT560: suitable for large-scale production, with a clamping force of 360 tons and a injection pressure of 250 Mpa.
