Shaanxi Allstate Technology & Manufacture Co., Ltd. is a manufacturer of machinery components. We are accredited with ISO 9001:2000
certification. Additional machining operation and surface treatment will be made if needed. Our products are widely used in agriculture, automobile, and chemical industry.
We manufacture and export various castings including investment castings, sand castings, die-castings and centrifugal castings. The yearly output of various castings is above 12000tons, which are widely used in metallurgy, automobile, chemical, ship and hardware engineering industry.
The materials used for castings include ferrous metal such as stainless steel, alloy steel, ductile iron and non-ferrous metal such as brass, aluminium, aluminum alloy, & zinc alloy.
Sand casting is the simplest and most versatile of all casting processes used to produce castings. This process uses wooden or metal patterns that are then placed in the split molding frame. The frame is then filled with sand and packed around the pattern. The mold is then separated and the pattern removed. Once the mold halves are reassembled, the resulting cavity is filled with the selected molten alloy. There are a variety of types of sand casting, including chemically bonded, clay bonded and oil bonded. The type of sand casting process used is dependent upon production speed requirements, the size of the casting, environmental concerns and cost considerations.
Our Investment casting is also known as the "lost wax" process. This process uses wax patterns assembled in tree forms on a runner. The completed assembly is coated with ceramic slurry, allowed to dry and then heated to melt out the wax leaving a ceramic mold into which the molten alloy is poured. Tolerances of 0.5 % of length are routinely possible, and as low as 0.15 % is possible for small dimensions.
Centrifugal casting is ideal for high quality cylindrical components. Centrifugal force is employed to exert pressure on the molten metal as it is poured into a spinning mold resulting in a dense part with a fine uniform grain structure. The integrity and wear resistance of these structures make them exceptional where there is frictional wear. Centrifugal castings are supplied in a semi or finished machine condition.
Die casting is a manufacturing process for producing accurately dimensioned, sharply defined, smooth or textured-surface metal parts. It is accomplished by forcing molten metal under high pressure into reusable metal dies. The process is often described as the shortest distance between raw material and finished product. We can supply are plating, shot blasting, heat treatment, anodizing, electrostatic painting, conventional machining, assembly, powder coating, polishing, buffing, sanding and washing.
Our Forgings are produced with the highest metallurgical reliability. Those parts are made of a variety of structural steel, tool steel, stainless steel, heat-resistant steel, super alloys, titanium, aluminum, magnesium and copper alloys to meet our customers' requirements on aerospace, automotive engineering, railway industry and many other advanced engineering industries.
