SpecialDongguan Precision CastingThere are many commonly used methods, such as: investment casting, plaster precision casting, ceramic precision casting, lost foam casting, metal casting, pressure casting, low pressure casting, differential pressure casting, vacuum suction casting, squeeze casting, Centrifugal casting, continuous casting, semi-continuous casting, shell casting, graphite casting, electroslag casting, etc.

1. Investment casting: Investment casting refers to a pattern made of fusible materials. Several layers of refractory coating are wrapped on the surface of the pattern to form a shell, and then the pattern is melted to remove the shell, so as to obtain a mold with no parting surface. , Casting method that can be filled with sand and poured after high-temperature roasting. The process is divided into three stages: wax mold manufacturing, shell manufacturing, and roasting and pouring;

2. Metal casting: metal castingDongguan Precision CastingIt is a method in which liquid metal is poured into a metal mold and solidified under the action of gravity. It can be used repeatedly for many occasions, so it is called long-lasting casting;

3. Pressure casting: Pressure casting is to press liquid or semi-liquid alloy into a metal mold quickly (filling speed can reach 5-50m/s) under high pressure (specific pressure is about 5~150MPa), and under pressure Method of solidification to obtain castings;

4. Centrifugal casting: pouring liquid alloy into the high-speed rotating mold, so that it can fill the mold and crystallize under the centrifugal force. This casting method is called centrifugal casting;

5. Lost foam casting: Lost foam castingPrecision cast steelAlso known as gasification mold casting or solid casting. It is a method of making a mold with a pattern made of foamed plastic, after which the pattern is not taken out, and the pattern vaporizes and disappears during pouring to obtain a casting.
