Investment Castings

Our steel castings are available in a wide weight range, from 100 gm to 20 kg, with the flexibility to provide customisable options to meet specific customer needs. Utilising advanced investment casting techniques, we deliver components that are reliable, resilient, and capable of withstanding demanding environments. Our products undergo a heat-treatment process to enhance mechanical properties, ensuring superior wear resistance, toughness, and corrosion resistance.

With a robust manufacturing capability, we efficiently manage high-volume orders, ensuring timely delivery and consistent quality for all casting requirements. These steel castings are ideal for load-bearing components such as switchgear gears, operating mechanisms, connectors, linkages, and more, providing the necessary strength and longevity required in electrical switchgear applications.

Material Standard Description
Steel ASTM A148 SAE / AISI 1040, 1030 Steel castings are used for high-stress, high-strength components such as electrical switchgear operating mechanisms and connectors.
DIN 17182 GS20Mn5(V) Used in critical parts where strength, toughness, and resistance to wear are required, such as switchgear linkages and gearboxes.
SCW480 A high-strength steel alloy used for load-bearing components like electrical switchgear gears, ensuring durability under mechanical stress.
Ductile Iron GGG 40, GGG 50 Ductile iron is known for its excellent strength, wear resistance, and shock absorption, making it ideal for switchgear housings, bushings, and terminal blocks.
IS 1865 Grade 400/18L, 450/12, 500/7, 400/15, 700/2 Provides enhanced strength and durability, often used in parts like circuit breaker housings and connectors in high-voltage applications.
ASTM A 536 Grade 65-45-12, 80-55-6, 60-40-18 Ductile iron grades are ideal for producing precision components with superior mechanical properties, such as bus bars and cable lugs in switchgear systems.
