Metal casting process for speed reducer output flange:

Baoding Guokun casting factory can offer you green sand casting process, resin sand casting process or shell mold casting process.

The process of Baoding Guokun sand casting involves several steps after producing a professional tool or mold, including:

1. Sand preparation: Mixing the silica sand with a resin binder and a catalyst that is conducive to hardening process.
2. Molding: Filling the sand and resin mixture to the sandbox, after assembling the mold which usually made of wood or aluminum. Please pay attention to the uniformity of resin sand filling. Uneven filling can lead to differences in sand mold strength.
3. Hardening: Hardening is very important in the furan resin sand casting process, which refers to the solidification and molding of resin sand in the mold. During the curing process, the resin binder undergoes a chemical reaction, making the resin sand hard and possessing a certain strength. The hardening time of resin sand is usually determined by the properties of resin binder and the required castings, and generally needs to be carried out under certain temperature and time conditions.
4. Mold Removel: Once hardening finished, the mold or pattern should be removed to form the required cavity of desired metal components.
5. Metal Pouring: Molten metal is poured into the above cavity.
6. Cooling: After the metal has cooled and solidified, the sandbox is broken apart to reveal the cast metal parts. Then we could trim, sand blasting and machine them according to drawings.

Why use sand casting process to produce these gearbox input flange or speed reducer output flanges?

Versatility: Sand casting process can be used to produce a wide range of shapes and sizes, from small & intricate parts to large & sample parts, weight up to 10,000 kgs.

Short lead time: Compared with die casting or Investment precision casting process, sand casting has short lead times because of short mold production time.

Widely material choice: Almost any metal can be sand mold casted, for example, cast steel, ferrous and non-ferrous cast iron, aluminum and bronze.

Low Cost: The sand casting of Baoding Guokun is cost-effective for small-quantity runs, and the molds are inexpensive to make, especially the wooden mold.

Baoding Guokun Machining Equipment

Metal for gear reducer output flange:

• Gray cast iron: ASTM A48 Standard Specification for Gray Iron Castings. This specification covers gray iron castings intended for general engineering use where tensile strength is a major consideration. Castings are classified on the basis of the tensile strength of the iron in separately cast test bars. The casting surface shall be free of adhering sand, scale, cracks and hot tears, as determined by visual examination. Baoding Guokun can manufacture various size worm gear reducer output flange in ASTM A48 Class 35 or HT250 cast grey iron. The grey iron is the most common cast iron due to its good castability, machinability, and vibration damping properties, although in situations requiring higher strength and impact resistance, ductile iron might be used instead.
• Die cast aluminum alloys
