Several aspects of mold protection need to pay attention to

As the most important production tool of an injection molding factory, it determines the shape, specification, size, and appearance finish of the product. The material of the hardware mold is steel, which is generally composed of a front mold/rear mold.

Protection of mold

Due to the specificity, precision, vulnerability and other characteristics of the mold, the safety protection of the mold is very important. The overall summary is as follows:

1. Rust prevention: Prevent rusting caused by water leakage/condensation/rain/handprints in the injection molding machine mold.

2. Anti-collision: Prevent the mold from being damaged due to the breakage of the thimble and the failure to retract the mold.

3. Deburring: Prevent mold burrs caused by cloth wiping/material flushing/hand wiping/nozzle pliers/knife touching.

4. Missing parts: prevent the mold from being damaged during use due to the lack of tie rods/washers and other parts.

5. Anti-pressure: prevent the mold from being crushed due to the mold being locked due to the remaining product.

6. Under-pressure: prevent mold damage caused by excessive low-pressure protection pressure.

Among them, the proportion of mold damage caused by broken thimble, thimble not returning in place, residual product in the mold, and lack of accessories is relatively high, and because it occurs more frequently, more than 85% of mold damages are caused by this reason. Yes, and mold maintenance costs are generally high, so how to avoid such situations is directly related to the interests of the injection molding industry.
