The injection molding material ring of the screw of the injection molding machine contains a lot of titanium dioxide! Many materials have been tried and corroded within one month! Is there any way to prevent corrosion of the screw! The raw material currently used is 9cr18mov! I heard that the corrosion resistance of the material can be improved by plating, titanium, and zinc plating! Can it work?

No best answer

The first step: first use stainless steel cleaning agent to remove oil, rust, and various substances on the surface. After three minutes of treatment, the workpiece is as bright as new, and the original luster of the workpiece can be restored without damaging the substrate of the workpiece. Anti-rust performance, safe to use and environmentally friendly, and non-volatile, leaving no residue.
Step 2: Stainless steel passivation solution can be used to prevent rust of stainless steel screws. It is simple to operate and only needs to be used at room temperature in a plastic tank. The passivation time is 1 hour. After passivation, the size and appearance of the workpiece will not change, and a passivation film is formed on the surface. , Can prevent the workpiece from rusting again, the workpiece will have a bright and clean surface after passivation, and at the same time can extend the service life of the stainless steel screw.
