Gravity Die Casting
Our Gravity Die Casting (GDC) division in Kolhapur specializes in producing high-quality, dimensionally stable, and durable aluminum components. GDC is ideal for larger, thicker-walled parts where strength, superior surface finish, and consistent quality are critical.
Gravity Die Casting Capabilities
Aluminum Melting Holding Furnace (Skelner Type, 1500Kg/Batch)
Enables large-scale, consistent melting operations.
Vertical Tilting GDC Machines
1000 mm x 800 mm platen size, C-frame construction
800 mm x 600 mm platen size, C-frame construction
Supporting Equipment
Band saw, belt sander, and bench grinder for trimming and finishing
Shot blasting machine for uniform surface finish
Electrical holding furnace (300 kg) for process flexibility
Aluminum heat treatment furnace (1000 kg per batch)
Crucible type oil-fired furnace (500 kg)
Quality Assurance in GDC
To achieve near-zero rejection rates, every GDC product undergoes thorough inspection supported by our state-of-the-art laboratory:
- Optical Spectrophotometer for alloy composition analysis
- Density Index Analyzer to control porosity
- Universal Testing Machine (UTM) for stress, elongation, and break tests
- Rockwell Hardness Testing for durability verification
- Degassing machines to ensure metal purity
Our Total Quality Management System (TQMS) ensures defect-free castings that meet both domestic and international standards.
Efficiency & Sustainability
By co-locating GDC operations with our aluminum alloy ingot manufacturing facility (Atharv Udyog), we leverage direct molten metal usage. This innovative process avoids the re-melting of ingots, providing an additional 5% saving in energy and cost, making our GDC process sustainable and eco-friendly.
