1. Combined structure blow mold
The half-side mold of the combined structure blow mold is processed by combining several pieces of metal separately. When the mold is processed by this method, it is necessary to separately process on each mold, and generally, there will be a certain processing error after the combination, and manual grinding and trimming are required. In recent years, this type of structure has been mainly applied to medium and large blow molds, as well as mold processing where product requirements are not high.
2. Mosaic structure blow mold
The half-side mold of the inlaid structure blow mold is inlaid by a piece of integral metal material and several pieces of hard metal material. The inlay method generally has the methods of casting inlay, press-in setting and bolting inlay. Casting inlays are mainly placed in the position where they need to be inlaid, cast in aluminum alloy, and then machined. Press-in inlay is a process in which the metal parts to be inlaid are machined, and then joined by press-in, and then machined until the molding is completed. Bolted inlays can be used to machine all the mold parts that need to be machined before bolting. At present, most of the molds used in the 200L series plastic drums are processed by aluminum alloy casting and inlaying.
