At present, metal casting is still the main method for the production of parts blanks, which has been widely used in industrial production and plays an important role in the machinery manufacturing industry. It works by using compressed air to uniformly inject the molding sand into the flask for pre-compaction, and then applying external pressure for compaction. The horizontal splitting and out-of-box injection molding machine uses the sand box for modeling, and the sand type is formed after the mold is unpacked. The advantage of this machine is that the sand making type has high dimensional precision, and the lower core is convenient, and the double-station lower core can be realized, the productivity is high, and the molding sand has less leakage. Our company combines the needs of the market and based on the strong professional and technical strength of our company, develops a fully automatic molding machine with independent intellectual property rights.
