Heavy Equipment Parts Manufacturing
Meco manufactures custom load-bearing parts for excavators, loaders, tractors and off-highway machinery—delivering finish-machined castings, forgings, CNC-machined components and AWS D1.1 weldments under one roof.
Why Off-Highway OEMs & Tier 1 Suppliers Choose Meco
Splitting raw castings or forgings, CNC machining and heat treatment across separate vendors leads to porosity disputes and launch delays. Meco delivers ready-to-assemble heavy components under one purchase order.

Heavy Equipment Parts Manufacturing FAQ
Do you supply finish-machined castings and forgings under one P.O.?
Yes. Meco pours or forges the raw blank (up to 100 kg), performs heat treatment, and completes all CNC milling, turning and cylindrical grinding in-house. You receive a ready-to-install part with single-source quality accountability.
How large a part can you cast, forge and machine?
We cast components up to 100 kg across sand, gravity, investment and die casting, machine prismatic housings up to 1016 × 508 × 635 mm, turn shafts up to Ø360 × 1000 mm, and hold precision-ground bearing journals and hydraulic bores to ±0.005 mm.
How do you verify load-bearing castings, forgings and weldments?
We perform Non-Destructive Testing (NDT)—including ultrasonic, magnetic particle, dye penetrant and X-ray inspection—alongside AWS D1.1 weld inspection, hardness/tensile testing, CMM verification to ±0.002 mm and full heat-lot traceability.
What order volumes do you support and who owns the tooling?
We support 10-piece prototype and service-part batches up to 100,000+ annual OEM production runs with no minimum order. When your program requires casting patterns, forging dies or fixtures, we build the tooling and you retain 100% ownership.
How do your Thailand and China factories reduce tariff and supply risk?
Meco operates IATF 16949:2016-certified plants in Thailand (20,000 m²) and China (16,000 m²), supported by U.S. engineering and headquarters in Richmond Hill, Ontario, Canada. Dual-country production lets off-highway OEMs reduce landed tariff costs and secure backup capacity.
How fast can we get a quote and DFM review?
We return a detailed quote within 24 hours of receiving your STEP/IGES files and 2D drawings, complete with DFM feedback on casting draft, machining stock and heat treatment that often reduces unit cost by 15–30%. See our metal part pricing guide.
