Capabilities

The machine list, with the numbers we sign off on.

Every machine group across both plants, the envelope it handles, the tolerance we will commit to on your drawing, and the materials we run on it every week. Filter it the way your engineers would.

Materials

What we cut every week.

Bar, plate, forgings and castings, bought from approved mills with EN 10204 3.1 certificates, or free-issued by you. Every heat number is traced to the part.

Larger than this? Ask. We machine oversize castings on partner floor-borers in Coimbatore under our own inspection.

Batch sizes & lead times

50 pieces or 50,000. Same process.

Samples go through the same PPAP or FAI route as series parts, so the first article you approve is the part you get at volume.

5–10 pcsSamples with full FAI report. 3 weeks from PO.
50–500Low volume and pilot lots. 4–5 weeks.
500–50,000Series production. 6–8 weeks to first lot, then weekly call-offs.
AnnualBlanket orders with 4 weeks of safety stock held in Coimbatore.

Beyond machining

Delivered ready to fit.

Most buyers want one supplier and one PO per part number. We manage finishing and assembly under our quality system and ship the part ready for your line.

Assembly & test

Bearing and seal pressing, helicoil and insert fitting, torque-audited sub-assemblies. Pressure-decay leak testing to 10 bar, 100% on EV and hydraulic parts.

Finishing

Anodising, hard anodising, passivation, zinc-nickel, phosphating, induction hardening and heat treatment through five audited partners within 25 km.

Marking & packing

Laser marking with part number, heat number and date code, or DataMatrix. VCI wrap and ISPM-15 crates for sea freight, returnable totes for domestic lines.
