At present, the company's products involve a wide range of industries, and are exported to the United States, Japan, Europe and other countries, and have a good supporting and cooperative relationship with several large multinational companies and group companies. quality management system.
Casting size and shape, good repeatability, with the characteristics of precision casting;
The surface finish of the casting is high;
The elimination of molds eliminates the sand mold and the manufacturing department, and eliminates casting defects and scraps caused by core making and core lowering;
Inconsistency and no mold taking, because taking the mold greatly improves the molding process, so that the mold and the box will cause casting defects and waste;
Disappears flaws and waste products without any different types of modeling agents, anhydrous, water, water, matter and roots;
The large sand mold of the disappearing model is all processed, the system is used, and the processing department and the waste sand treatment are cancelled.
Easy to drop sand, reduce the workload and intensity of labor intensity;
Reduce the edgeless burrs of castings and increase the lap joint workload by 50%;
Reasonable risers can be set in the ideal, which are not negated by traditional factors such as parting and mold casting, and reduce internal defects;
Eliminate the negative pressure casting of the mold, the filling and replenishment of the polymetallic structure, and the density of the casting is reduced;
Improve the process yield and production efficiency of combined casting, multiple pieces in one box, and large castings;
The machining allowance is reduced and the machining cost is reduced.
The metals used for aid mainly include zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys, although die-cast iron is rare but feasible. The more special die-casting metals include ZAMAK aluminum-zinc alloy and the standards of the American Aluminum Association: AA380, AA384, AA386, AA390, AZ91D magnesium. The characteristics of die-casting of various metals are as follows:
1.Aluminum: Light weight, high dimensional stability when making complex and thin-walled castings, strong corrosion resistance, good mechanical properties, high thermal and electrical conductivity, and high strength at high temperatures.
2.Lead and tin: high density and extremely high dimensional accuracy not available as special anti-corrosion components. For public health reasons, this alloy cannot be used in food processing and storage equipment. Alloys of lead, tin and antimony (which also contain a little copper) can be used to make hand lettering and bronzing in letterpress printing.
3.Magnesium: Easy to machine, high strength-to-weight ratio, and the lightest of commonly used die-cast metals.
Die casting is one of the advanced metal forming methods. It is an effective way to achieve less chips and no chips.It is widely used and developed rapidly. At present, die-casting alloys are no longer limited to non-ferrous metals such as zinc, aluminum, magnesium and copper, but are also gradually expanding for die-casting cast iron and steel castings.
The size and weight of the die-casting parts depend on the power of the die-casting machine. Due to the increasing power of the die-casting machine, the size of the casting can be from a few millimeters to 1-2m; the weight can be from a few grams to tens of kilograms. Abroad can die-cast aluminum castings with a diameter of 2m and a weight of 50kg. Die casting parts are no longer limited to the automobile industry and instrument industry, and gradually expanded to other industrial sectors, such as agricultural machinery, machine tool industry, electronics industry, defense industry, computers, medical equipment, clocks, cameras and daily hardware. industry. In terms of die-casting technology, new processes such as vacuum die-casting, oxygen-added die-casting, precision and fast-density die-casting and the application of soluble cores have emerged.
