Four stages, one accountable team: melt, cast, heat-treat and inspect, all on the same floor.

A continuous melt of AC2A, LM16 or Al-Si7 is held to spec and verified by optical-emission spectrometer before any metal enters a die. Holding-bath temperature is PLC-controlled and logged against the part-specific recipe.

Cycle time, pour profile and die-temperature traces are logged for every shot, giving us the process-capability data Tier-1 customers need at PPAP and through volume production. Part-weight range 100 g to 1.5 kg.

T6 and customer-defined heat-treat cycles run under logged time-and-temperature traces against the control plan. Mechanical-property validation is performed in-house every heat-treat batch via tensile testing.

Our in-house MetChem laboratory provides spectrometer chemistry analysis, tensile testing and dimensional / metallurgical inspection on the same floor as the casting line. Reports are issued against a robust control plan and made available to customers on request.
Each alloy is matched to a component's role in the brake system: structural caliper bodies, bore-tolerant cylinders, or weight-optimised brackets. All three are cast in the same plant under the same QMS.

We work with customer engineering from the first sketch, feeding back manufacturability, value-engineering opportunities and tooling realities before a die is cut.
We review every new geometry against gravity-die-casting realities (wall sections, draft, gating, hotspots) and feed changes back during RFQ, before a die is ordered.
On running programmes we propose weight, cycle-time and material-cost reductions. The VAVE tandem master cylinder is our anchor case: a multi-feature casting, fully re-engineered.
Tools are designed, built and reworked at our sister facility, Renuka Engineers, keeping die ownership and turnaround inside one accountable group.
From first-off samples through dimensional layout, capability studies and PPAP submission: the documentation set Tier-1 buyers require before SOP.
Every programme begins and ends with the customer. You bring the part; we bring its manufacture. Through this loop we take your drawing to validated, sampled castings — while design authority for the product stays with you at every step.
Review casting design against our gravity die-cast process constraints.
Thermal and flow simulation to optimize gate, riser, and cooling.
Die design and CNC machining in-house via Renuka Engineers.
Value Engineering, Process approval documentation per IATF 16949.
First-article production runs and metallurgical validation.
Control plan finalization, SPC setup, full-rate production.
Manufacturing process and tooling design sit with MAP Alloys; product-design authority remains with the customer — consistent with the scope of our IATF 16949:2016 certification.
