Manufacturing Capabilities

Our OEM replacement service starts with your sample or drawing. We reverse-engineer the part, select appropriate materials, and manufacture to specifications. For critical components (pins, shafts), we apply heat treatment to match OEM hardness. For wear components, we offer upgraded materials (Hardox) for extended life. Every replacement part is dimensionally inspected against the original before shipping.

Quality Assurance

Reverse-engineering verification: every replacement part dimensionally inspected against the original sample

Hardness matching to OEM spec with durometer/tester records

Material selection review documented for each replacement part

Material test certificates (MTC) provided with every shipment

ISO 9001:2015 certified quality management system

Frequently Asked Questions

Q: Can you manufacture from a broken sample part?

A: Yes, send us the broken part and we'll reverse-engineer it. We can reconstruct missing dimensions and manufacture a complete replacement.

Q: Can you improve on OEM material specifications?

A: Yes, we can upgrade materials - for example, using Hardox 400 instead of standard steel for wear components, or upgrading to Grade 10.9 hardware.

Q: What is the typical lead time for replacement parts?

A: Simple parts: 2-3 weeks. Complex welded assemblies: 4-6 weeks. We provide a confirmed lead time with our quote.
