Overview

Mechpart produces hot-forged and cold-forged components that deliver the grain-flow integrity and fatigue resistance demanded by heavy-industry applications. Our forging capabilities cover part weights from 0.1 kg to 50 kg in carbon steel (1045, 4140), alloy steel (4340, 8620), stainless steel (304, 316, 17-4PH), and aluminum alloys, with secondary heat-treatment options including quench-and-temper, normalizing, annealing, and induction hardening. Closed-die, open-die, and upset forging processes are available, supported by in-house die design and CNC finish machining for net-shape delivery.

End-use segments include automotive driveline (connecting rods, steering knuckles, axle shafts), heavy machinery (track links, bucket pins, ripper shanks), oil-and-gas (flanges, valve bodies, pup joints rated to API 6A), and power generation (turbine blade preforms, generator shaft couplings). Components are routinely tested to ASTM, ASME, and customer-specific standards with full mill-cert traceability included as standard—not as a line-item surcharge.

Why forge with Mechpart? Three words: reliability at scale. Our forging supply chain is vertically integrated from billet procurement through finish machining, eliminating the finger-pointing that plagues multi-vendor projects. Every shipment includes a dimensional inspection report, material certification, and surface-quality documentation. Lead times of 3–5 weeks from die approval, with MOQs as low as 100 pieces for development programs. Forge ahead with a partner that understands the difference between a casting and a forging—and when your application demands the latter.

Frequently asked

Why choose forging over casting?

Forging delivers continuous grain flow — higher fatigue strength and impact resistance for load-bearing parts.

Do you heat-treat in-house?

Yes — normalize, quench & temper and anneal to your hardness and property targets.

Can you forge then machine to tolerance?

Yes — we forge near-net blanks and CNC-finish critical features to ±0.01 mm.

What testing do you provide?

Ultrasonic, magnetic-particle, hardness and tensile testing with full reports.
