What Are The Common Problems in The Test of Crate Mould?

If you want to solve the common problems in the mould test of the Crate Mould(FURNITUREMOULD), you have to know where the problem is in order to solve the problem. Let's talk about some common problems in the test of crate mould.

1. The main runner die bonding

The solution to the problem is to polish the main runner, with the nozzle coinciding with the mould centre, reduce the temperature of the crate mould, shorten the injection time, increase the cooling time, check the nozzle heating ring, polish the surface of the crate mould, and check whether the material is contaminated.

2. Difficult demoulding of plastic parts

The solution to the problem is to reduce the injection pressure, shorten the injection time, increase the cooling time, reduce the temperature of the crate mould, polish the surface of the crate mould, increase the demoulding slope and reduce the gap at the insert.

3. Poor dimensional stability

The solution to the problem is to change the temperature of the charging barrel, increase the injection time, increase the injection pressure, change the screw back pressure, increase the temperature of the crate mould, reduce the temperature of the crate mould, adjust the feed amount, and reduce the return ratio.

4. Surface corrugation

The solution to the problem is to adjust the feeding amount, raise the mould temperature of the crate, increase the injection time, increase the injection pressure, raise the material temperature, increase the injection speed, and increase the size of the sprue and gate.

5. Plastic warpage and deformation

The solution to the problem is to reduce the crate mould, reduce the material temperature, increase the cooling time, reduce the injection speed, reduce the injection pressure, increase the screw back pressure and shorten the injection time.
