Our Foundry Infrastructure

Moulding Facility

Moulding Facility

Our moulding section is equipped with an ARPHA 450 with a box size of 24” x 28”, ensuring strong, uniform and dimensionally accurate moulds.

The ARPHA process provides excellent compaction and consistent mould hardness, resulting in superior surface finish, reduced casting defects, and repeatable quality in every batch.


Sand Plant

Sand Plant

Our sand preparation system includes a Shree Shakti Mixer and Akshay Foundry Equipments Sand Cooler, ensuring uniform sand mixing and controlled temperature management.

This controlled process maintains optimal mould strength, permeability, and moisture balance, resulting in improved surface finish, dimensional stability, and consistent casting quality.

Advanced Sand Plant

  • Mold hardness tester

Melting Facility

Melting Facility

Our melting section is equipped with a 550 KW Inductotherm Furnace (2 Crucible) with a 500 Kg capacity, enabling precise temperature control and uniform metal melting.

This advanced induction system ensures consistent chemical composition, improved metallurgical properties, and reliable casting quality across all production batches.

Advanced Melting Technology Enables

  • Precise Temperature Control
  • Uniform Metallurgical Properties
  • Consistent Chemical Composition

Shot Blasting

Shot Blasting & Fettling

Our finishing section includes a Hanger Type Shot Blasting Machine and 3 Bench Grinders to ensure superior surface preparation.

The shot blasting process effectively removes sand, scale, and surface impurities, while fettling operations ensure proper edge finishing and dimensional accuracy.

These processes deliver clean, smooth, and defect-free castings ready for dispatch or precision machining.

Quality Control & Testing Facilities

Quality is the foundation of our foundry operations. Our well-equipped in-house laboratory and inspection systems ensure strict monitoring at every stage — from raw material testing to final casting approval.
