Precision Investment Castings that we offer are produced using lost wax process. It allows the production of parts in high or small volume with extraordinary precision in most cast able metals. We are counted among the top companies, which are engaged in manufacturing, supplying and exporting Precision Investment Castings. The manufacturing and testing of our Precision Investment Castings are done under the supervision of experts Inhouse.

Characteristics

• High production rates, particularly for small components.
• High dimensional accuracy and consistency.
• High integrity castings.
• Extremely good surface finish obtained.
• Complex shapes can be cast.
• Long or short runs can be accommodated.
• Machining can be eliminated in most cases.
• Minimum shot blast and grinding needed.
•  Almost any alloy can be cast.

Lost Wax Process

• Special Wax is injected into metal die to make wax patterns.
• Wax patterns (replica of part) assembled into a cluster around a wax runner system.
• The “Tree” of patterns then coated with layers of a refractory material.
• Each layer being dried or chemically cured before the next layer is applied.
• Assembly is heated to remove the wax & fired at high temperature to bond the mold.
• The mould is heated and molten metal poured.
• When cool, the mould material is removed.
• Castings are removed from the runner system for secondary process and final finishing.

Our capability

• Production Capacity : 1600 Metric Tons / Annum
• Job Handling Capacity : From few grams to 195 Kg. Single Piece

Shell Mould Castings that we offer are manufactured using conventional molding and metal casting process. The mold is formed around a pattern by ramming sand, mixed with the proper bonding agent, onto the metal or wood pattern. Molten metal is poured into the mold, and after it has solidified the mold is broken and castings are removed for secondary process and final finishing. The name of our company is listed among the prominent Manufacturers, Exporters and Suppliers of Shell Mould Castings. Buyers prefer to buy Shell Mould Castings from us as we make them available at the most reasonable prices.

Advantages

• Better surface finish
• Better dimensional tolerances.
• Reduced Machining.
• Less foundry space required.
• Semi skilled operators can handle the process.
• The process can be mechanized.

 
Disadvantages

• The raw materials are relatively expensive.
• The process generates noxious fumes which must be removed.
• The size and weight range of castings is limited.

 
Applications

• Crankshaft fabrication
• Steel casting parts, fittings
• Moulded tubing fabrication
