9-Stage Manufacturing Process
From Certified Steel Inward to Finished Dispatch
At M/s A R Auto Parts Engineering, we follow a disciplined, sequential 9-step production flow strictly adhered to across our 100 Ton monthly manufacturing operations.
Raw Material Received
Certified carbon & alloy steel billets inspected with mill test reports and heat code marking.
Cutting Process
Automated circular bandsaw and shearing machines cutting billets to precision weight and length.
Forging Process
150 kW Induction heating followed by closed-die forging on 200T friction & power presses.
HT Process
Controlled Heat Treatment (Normalizing, Quenching & Tempering) for optimal grain structure.
Shot Blasting Process
High-velocity shot blasting descaling surfaces to achieve a clean metallic finish.
Machining
Multi-axis CNC turning and VMC milling delivering micron-level tolerances down to ±0.01 mm.
Final Inspection
100% QA verification utilizing Mitutoyo micrometers, bore gauges, height gauges, and visual inspection.
Packing
Protective anti-rust oil coating, individual moisture barrier wrap, and heavy-duty corrugated/wooden crates.
Dispatched
Logistics coordination and on-time dispatch with full traceability documentation to OEM clients.
In-Depth Manufacturing Operations
Raw Material Receipt & Cutting
Incoming carbon and alloy steel billets (EN8, EN9, EN19, EN24, SAE4140) are verified against manufacturer mill test reports with heat code traceability. Billets are precision-cut across our 3 dedicated cutting machines to exact predetermined weight.
- 3 Cutting machines for high-capacity billet preparation
- 100% heat number tagging on every raw material lot
Forging, HT & Shot Blasting
Rapid 150 kW induction heating brings steel billets to uniform plasticity without surface oxidation. Closed-die forging under our 200T pneumatic friction press aligns the grain flow for superior tensile strength, followed by normalizing heat treatment and shot blasting for descaling.
- 200T friction press + 100T/150T power trimming presses
- Shot blasting descaling providing smooth Ra bonding surfaces
Multi-Axis CNC & VMC Machining
Forged blanks undergo high-accuracy turning, boring, facing, threading, and milling across our 6 CNC Turning Centers and 1 Vertical Machining Center, maintaining tight micron tolerances down to ±0.01 mm for critical automotive and hydraulic components.
- 6 CNC machines + 1 VMC + Drilling machine
- Strict concentricity and GD&T compliance to client CAD
Inspection, Packing & Dispatch
100% final quality clearance using our Mitutoyo micrometers, bore gauges, and height gauges. Verified parts are treated with high-grade anti-rust corrosion inhibitors, packaged in heavy corrugated or wooden boxes, and dispatched on-time.
- Calibrated Mitutoyo metrology sign-off
- Moisture-proof packaging with full lot traceability
