We have very good corrosion resistance
Plastic food container moulds(https://www.rdmould.com/produc....t/household-mould/fo as a key link in the food packaging industry chain, are mainly responsible for producing various disposable or reusable food containers through injection molding processes, such as crisper boxes, snack boxes, beverage bottles, etc. In view of its direct contact with food, the corrosion resistance of the mold is crucial. Once the mold is corroded, it will not only lead to reduced mold accuracy and defects in the produced products, but may also cause harmful substances to migrate into the food, seriously threatening the health and safety of consumers.
To ensure that plastic food container moulds have excellent corrosion resistance, we must start with the selection of raw materials. Under normal circumstances, the selection of mold steel is very important to ensure that the mold will not be easily corroded even in a humid production environment. In addition, pre-hardened mold steel, through specific alloy composition design and heat treatment process, can also show excellent corrosion resistance and is suitable for making high-quality food container moulds.
