Company Case

Investment casting (lost wax casting) :

Principle: The selection of appropriate investment materials (such as paraffin) to manufacture investment molds; Repeat the process of dipping refractory paint and spreading refractory sand on the investment mold, hardening the shell and drying; Then the internal investment mold is dissolved to obtain the cavity; Calcined shell to obtain sufficient strength, while burning off the remaining investment material; Finally, the required metal material is poured, solidified and cooled, and the sand is cleaned after hulling, so as to obtain the finished product with high precision.

Features: It can produce castings with high dimensional accuracy, good surface quality and complex shape, close to the final shape of the part, and can be used directly without processing or little processing, which is an advanced process of near-net shape formation. Widely used in aviation, weapons, electronics, petroleum, chemical, energy, transportation, light industry, textile, pharmaceutical, medical equipment, pumps and valves and other sectors.

Ceramic mold casting:

Principle: Use ceramic paste to make a cast to produce castings. Ceramic slurry is composed of ethyl silicate hydrolysate and fine refractory sand with relatively pure texture and high thermal stability (such as fused quartz, zircon, corundum, etc.). In order to make the ceramic slurry gel in a short time, calcium hydroxide or magnesium oxide is often added as a catalyst.

Features: The surface roughness of ceramic castings can reach Ra10~1.25 microns, and the dimensional accuracy is as high as 3~5, which can achieve the purpose of less and no cutting. Short production cycle, high metal utilization rate, mainly used for casting large thick wall precision castings and various molds

Metal mold casting

Principle: The liquid metal is poured into the metal mold, the mold is filled under the action of gravity or other external forces, and the casting is obtained after cooling and solidification. Metal molds can be used repeatedly.

Features: The cooling speed of the casting is fast, the structure is dense, and the mechanical properties are good. High production efficiency, suitable for mass production of castings with simple shape and high dimensional accuracy requirements, such as aluminum piston, copper sleeve, etc.

Pressure casting

Principle: The liquid or semi-liquid metal is quickly pressed into the metal mold cavity under high pressure and solidified. Pressure casting is usually performed using a die casting machine.

Features: High production efficiency, high dimensional accuracy of castings, good surface finish, can cast thin-wall parts with complex shapes. However, the equipment cost is high, and the manufacturing of die-casting molds is difficult and costly, which is suitable for the production of small, thin-walled, high-precision parts such as auto parts and electronic product shells.
