Maintenance and self inspection of plastic injection mold

Issuing time:2020-07-20 08:47

Plastic injection mold sometimes has some problems, which may lead to unqualified parts, such as: material residues in the mold, rust, cracks or other damage to the mold, and air or gas trapped in the mold. Product rejection means a longer production cycle, so it is important to ensure that the quality remains at a high level. So the self inspection and maintenance of plastic injection mold is particularly important.

Basic plastic injection mold maintenance procedures

Basic maintenance inspection of plastic injection mold before and after each injection cycle. This will help keep the part to specification and ensure that no debris or other foreign material damages the mold.

1. Clean the cavity of plastic injection mold with mild solvent. The residual material in the cavity will affect the shape and structural integrity of the parts. Simple cleaning helps a lot.

2. Use compressed air to blow out dust, debris and water. Especially in the complex plastic injection mold, they will affect the parts and cause greater damage in the production cycle.

3. Before storing the mould, please make sure that the whole mould is completely dry. In order to avoid plastic injection mold rust, rusty mold is more likely to fail or damage, and will produce a higher proportion of waste products.

4. Check all other areas of runner, gate and mold. It is worth noting that the mold cavity is not the only area to be inspected during maintenance. Debris and water can also cause serious problems in other parts of the mold. Also make sure to check and clean these areas.

5. Check the plastic injection mold hardware and connector. Such as bolts, plates and other parts. Check them for wear, fit, tightness and other standard maintenance issues.
