Dewaxing Casting

Dewaxing casting, a precision casting method.

Suitable for carbon steel, chromium-molybdenum steel, tool steel, wear-resistant heat-resistant steel, stainless steel, super alloy Monel, Hastelloy, nickel-cobalt alloy steel, high chromium cast iron, aluminum alloy, copper alloy, titanium alloy, etc.

Dewaxing Casting

Dewaxing casting products have the following characteristics:

1. Complex shape
2. Fine and beautiful surface
3. Single-mode, one-piece
4. Minimal processing program
5. Precision Dimension Casting
6. Reduce production costs
7. Precision and high strength

Used in industrial valves, flow meters, pumps, disks, pipe fittings; various machines, internal combustion engines, engines, heat exchangers, impellers; construction, sanitary, door locks, marine hardware parts; pneumatic, electric, hydraulic tools, hand tools, stamping tool parts; auto, motorcycle, vehicle, bicycle, aerospace, needle car, textile machinery parts; medical, sports equipment, computer business machine parts and other industries.

The dewaxing process requires an aluminum mold. The wax is pressurized into an aluminum mold to make a wax embryo, which is a replica of the true shape of the product produced. For each casting process, this wax embryo must be manufactured first. Several wax embryos are composed into three strings, which are repeatedly immersed in mud (or stone mortar) repeatedly, embedded in the outer layer and dehumidified and dried, and the ceramic shell is made into 9mm. (5-7 layers) thick, then put this tree string into a high-temperature 140-160 ° C oven or high-pressure steam pot to dissolve wax embryos until it becomes a hollow pottery shell.


This hollow ceramic shell is sintered at 1000 ℃ -1150 ℃ according to different alloy materials. The molten metal is immediately cast into the ceramic shell. After cooling, the outer ceramic shell is broken, sandblasted and cleaned, and cut. Grinding and heat treatment. Finishing, machining, polishing, etc.

Essai can produce precision castings and finished parts of various metal materials such as small stainless steel, carbon steel, alloy steel, etc. with dimensions less than 200 × 200 × 300mm and weight less than 10KG according to the world's major standards.

1. We recommend participation at the beginning of product design, provide feasibility assessment on the manufacturing side, improve product manufacturability for customers, save manufacturing costs, and provide optimal manufacturing solutions.

2. Provide customers with comprehensive solutions covering a variety of metal forming processes to achieve a "custodial" one-stop service.

Essai has very perfect investment casting production equipment, machining equipment, and advanced physical and chemical analysis and testing equipment, which can meet the customer's product requirements at different levels and the comprehensive requirements of physical and chemical properties and non-destructive testing. Existing spectrum analyzers, tensile testing machines, X-ray flaw detectors, magnetic particle flaw detectors, portable magnetic particle flaw detectors, metallurgical microscopes, and other testing equipment, at the same time, companies are constantly introducing world-leading technology and professional technical personnel To expand advanced production and testing equipment, the company's technical strength is becoming stronger and stronger, and its economic strength is constantly developing and growing.

The materials for dewaxing precision casting are hardly restricted by materials, such as cast iron, stainless steel, aluminum alloy, superalloy, nickel-based heat resistant alloy, etc. They can be manufactured by dewaxing precision casting, high precision, high efficiency, etc.
