to 20+ countries
One integrated facility, shipping worldwide with DDP pricing, correct HS codes and full compliance documentation. We handle customs, tariffs and logistics so your landed cost is clear from day one.
Multi-process manufacturing under one roof — CNC, casting, forging, sheet metal & molding, with in-house inspection
Why buy direct from the factory
Online marketplaces and local job shops add cost, time and a layer between you and the people making your parts.
| MechPartfactory-direct | Online marketplaces | Local job shops | |
|---|---|---|---|
| Pricing | Factory-direct, no middleman markup | Platform fee + supplier margin | Higher overhead, regional rates |
| Lead time | Quote in 24h · ship in days | Quote in 24h, but routed to 3rd parties | Days to quote, queue-dependent |
| Minimum order | No minimum — 1 piece to 1M+ | Often minimums apply | Setup fees discourage small runs |
| DFM feedback | Free, from our own engineers | Automated / limited | Varies by shop |
| Full process range | CNC, casting, forging, sheet, molding | Network-dependent | Usually one process |
| Traceability | Heat-lot certs + inspection reports | Depends on supplier | Often limited |
| IP / NDA | Signed NDA, encrypted, never shared | Shared across a network | Generally yes |
| You talk to | The factory making your parts | A platform account manager | The shop directly |

Explore Industrial Equipment →“Our gearbox shaft had no drawings and a 16-week OEM lead time. They measured a worn sample, hardened and ground a replacement to AGMA spec, and shipped in nine days.”
“Started at 50 prototypes, now running 50,000+ units a year of the same part with consistent quality. The dealer portal makes reordering effortless.”
“Used their metal 3D printing for functional titanium brackets, then CNC-finished the critical faces. Near-wrought strength, and we iterated three designs in under two weeks.”
“Investment-cast housings with tight internal passages that two other shops called impossible. Mechpart nailed the geometry and the surface finish on the first article.”
“We moved our forged components here after two suppliers let us down. Three programs in, 100% on-time, full material certs every shipment. Communication is fast despite the time zone.”
“Their design-check flagged two thin-wall issues before we ordered — saved us a full revision cycle and roughly $18k of rework on the first batch. Parts arrived in spec, on time, with CMM reports.”
“Stamped stainless brackets were burr-free and dimensionally consistent across 10k units.”
“We have ordered three batches of 5-axis machined housings. CMM reports came back within +/-0.005mm as promised. Fast communication and the DFM feedback saved us a redesign.”
“Had PA12 and Inconel parts in under two weeks. Dimensional accuracy was spot-on.”
“Closed-die forged steel flanges with great grain flow. Material certs and hardness all checked out.”
“No sink marks or flash. Tooling was done quickly and the parts fit our assembly perfectly.”
“Needed odd-size shoulder screws in small quantity. Delivered fast and exactly to print.”
