★ Process Overview

When castings won't cut it,
you forge.

Forging deforms heated or cold metal under high compressive force to produce parts with continuous grain flow aligned to the part's geometry. The result: parts with 20-30% higher fatigue strength than equivalent castings, no internal porosity, and superior ductility.

Magnus partners with 50+ Indian forging plants ranging from 50-ton drop hammers to 8,000-ton press lines. We've shipped over 6 million forged components — automotive crankshafts and connecting rods, agricultural shafts, oil & gas flanges, railway couplings, and aerospace blanks — to OEMs across 28+ countries.

India is one of the world's largest forging producers, with global-leading plants in Pune, Coimbatore, and Belgaum specifically certified for safety-critical automotive and aerospace work. Magnus has audited 200+ Indian forging plants and curated the 50 best for our supplier network.

★ The Forging Process

Six steps from
billet to finished part.

1
Billet Cut

Raw bar stock sheared to weight per shot, weighed and verified.

2
Heat

Billet heated to 1,100-1,250°C in induction or gas furnace.

3
Forge

Drop hammer or press deforms hot billet into die cavity in 2-5 blows.

4
Trim

Flash trimmed off with trim die. Hot or cold trimming based on size.

5
Heat Treat

Normalising or Q&T to achieve mechanical properties per spec.

6
Finish & QC

Shot blast, machining, NDT, dimensional, packaging, shipment.

Australian rail operator's IRS-spec coupler sourcing.

An Australian freight rail operator needed 4,000 IRS-spec couplings per year, replacing a Chinese supplier with quality issues. Magnus qualified two Pune-based forging suppliers, managed AS 9100 audit equivalent, and ran 6 months of dual-source production validation.

★ Frequently Asked

Forging
questions, answered.

Forging vs casting — when do you choose forging?
Choose forging when (1) the part sees cyclic or impact loading (crankshafts, gears, suspension), (2) failure is safety-critical (aerospace, rail, oil & gas), or (3) you need maximum strength-to-weight (aerospace, motorsport). Choose casting when geometry is too complex for forging dies or when volumes are low and cost per part is critical. Forging gives 20-30% higher fatigue strength but is 30-60% more expensive per part.
What's the difference between closed-die and open-die forging?
Closed-die (impression-die) forging shapes the metal between two engraved dies — produces near-net-shape parts with tight tolerances, typical for crankshafts and connecting rods. Open-die forging hammers a heated billet between flat or simple-shaped dies — used for very large parts (shafts >500mm), low volumes, and where machining-from-blank is acceptable. Magnus suppliers cover both.
How does cold forging differ from hot forging?
Cold forging deforms metal at room temperature — produces tighter tolerances (±0.05mm), better surface finish, and improved strength via work hardening. Used for fasteners, small precision parts, and components needing minimal machining. Hot forging (above recrystallisation temp) is preferred for larger parts and complex shapes where ductility matters. Most Magnus forging work is hot; cold forging available for fasteners and small precision parts.
What heat treatments do you offer?
All standard heat treatments are available in-house at most Magnus forging suppliers: normalising, full annealing, isothermal annealing, quench & temper (Q&T), induction hardening, case carburising, gas nitriding, salt-bath nitrocarburising. Solution treatment and ageing for PH stainless and aluminum alloys also supported. Heat treatment is documented with continuous chart recording.
Can I get NDT inspection on every part?
Yes. For safety-critical applications, we offer 100% NDT inspection on every forged part: magnetic particle (MPI) for ferrous, dye penetrant (DPI) for non-ferrous and stainless, ultrasonic (UT) for internal defect detection on critical parts, eddy current for surface flaws. NDT operators are ASNT Level II/III certified. Inspection costs are typically 2-5% of part price.
How does India compare to China for forging?
India is the world's second-largest forging producer after China, with particular leadership in automotive forging (Bharat Forge, Mahindra Forgings) and railway forging. For most carbon/alloy steel forgings, India is now 5-12% cheaper than China on landed cost, with comparable or better quality for IATF 16949 work. Lead times from India are typically 1-2 weeks shorter to US/EU destinations than from China.
