Vertical parting boxless injection molding machine and horizontal parting boxless injection molding machine

The injection molding machine uses compressed air to evenly inject the molding sand into the sand box for pre-tightening, and then applies pressure for compaction. Commonly used are vertical parting boxless injection molding machines and horizontal parting boxless injection molding machines. The vertical splitting boxless injection molding machine does not use a sand box for modeling. The molding sand is directly injected into the molding chamber with a template. The size of the sand mold produced is high. There are cavities on both sides of the sand box. The productivity is high, but the core setting is difficult and the molding sand is Strict quality requirements. The horizontal parting and unboxing injection molding machine uses a sand box for molding. After the sand mold is built, it is closed and unboxed. It is convenient to set the core and has high productivity.
