Plastic injection molds have many benefits, but corrosion is still a potential problem. Although there are many ways to minimize corrosion, once a problem occurs, you will have to replace the Stool Mould or find out whether corrosion will transfer from the mold to the part. Replacing plastic injection molds can be a time-consuming and expensive process. If nothing else, it may leave you behind plan.

If there is little or no risk of transferring corrosion from the mold to the final product, then this will give you time to make a new mold without having to exit the existing mold.

First, you must consider the material of the mold. If it is metal, corrosion can be transferred to the final product, especially if the parts are made of the same material. Contaminants are likely to appear on the surface of the product because that is the part directly exposed to the problem. At least this will make it easy to identify if there is a problem.

The risk that some corrosion will continue is small (largely because it is theoretically possible), and for plastic injection molds, this possibility is small. If the molded product is not made of the same material as the injection mold, the risk is lower.

In order to make your mold have the same performance as the metal mold and reduce the risk of plastic corrosion, you can cover some high-temperature plastics (such as nylon) on the metal mold. The plastic layer acts as a protective barrier between the metal and the product, including protecting the final product from any corrosion that occurs on the metal itself. Using high-temperature plastics allows you to continue to meet other specifications during processing, such as minimum temperature or resin requirements.

Plastic also helps protect metal molds. Constant exposure to heat and degraded resin will promote corrosion. With an additional plastic barrier, the metal is exposed to fewer elements that can cause corrosion.

For some types of molds, such as Package Mould, the risk of corrosion from the mold to the final product is greater than other types. By carefully planning, you can greatly reduce the chance of problems being passed on to the final product.
