For goggle PVC frame mould steel, there are some options: P20, 718, 2316, ETC. Normal PVC material is corrosive. So if goggle frame made with normal PVC material, the mould steel have to be stainless. Stainless steel 2316 is wonderful choose. But actually as protection products, goggle touch human skin tightly, so this product have to use environment-friendly PVC material. This kind of PVC material, doesn’t have corrosion. Then we can use P20 or 718 steel to make this mould. As mould supplier, we follow client’s requst.
