How to make your chair mold durable?
In order to prevent your chair mold cavity and core from being rusted by plastic materials, you need to ensure that the steel is high chromium and has a hardness greater than HRC33. If you will use some recycled materials for injection
molding, your chair mold needs to be hard chrome plated. Otherwise, you need to polish from time to time. For some chair backs, the design is very complicated, there are a lot of material bonding lines, and some air cannot be discharged
when the material is filled and flows. For this, you may need to analyze through mold flow, and there are many areas in the chair mold that need to be ventilated.
