The auto component supply chain in Tamil Nadu — particularly around Ambattur, Thirumulaivoyal, and Sriperumbudur — runs on tight material schedules. Press shops need specific slit widths of CR coil, often in multiple widths for different die sets. The traditional sourcing model is to buy slit coils from a steel distributor or service centre, which means accepting their standard slit widths, their lead times, and their pricing — all of which are set for their convenience, not yours.
What is Coil Slitting Job Work?
Job work coil slitting is an arrangement where you — the buyer — source your own master coils from a steel mill or trader, and then send those coils to a slitting facility for processing to your specific widths. You pay a processing fee per tonne, and receive your slit coils back, ready for your press line.
This is different from buying slit coils where the processor sources the steel, slits it, and sells you finished slit coils at a mark-up. With job work, you control the material — grade, thickness, source mill — and pay only for the slitting service.
The Cost Advantage: You Control the Raw Material
When you buy slit coils from a distributor, you're paying for the steel, the slitting, the distributor's margin, and any financing cost embedded in their pricing. When you source master coils directly from a mill or authorised dealer and send them for job work slitting, you eliminate the distributor's margin on the steel — which can be significant on CR coil volumes.
For auto Tier-2 suppliers managing thin margins, this material cost control can be the difference between a profitable and unprofitable quarter. The processing fee for job work slitting is transparent and negotiable based on volume.
The Time Advantage: Local Processing vs. Distributor Lead Times
A standard slit coil order from a distributor based in Mumbai or Pune typically carries a lead time of 7–14 days once you factor in slitting scheduling, transport time, and documentation. For a press shop running weekly production schedules, that lead time creates inventory pressure — you need to order ahead and carry safety stock.
With local job work slitting in Chennai — at a facility like MVEE Industries in Thirumulaivoyal — typical turnaround is 2–4 working days. You can replenish slit coil stock faster, carry less inventory, and respond more quickly when your OEM customer changes specifications or increases order volumes.
Why Tamil Nadu Location Matters
MVEE Industries is located in Women's Industries Estate, Thirumulaivoyal — within 15–20km of the major auto component clusters in Ambattur and on the route to Sriperumbudur. This means you can physically deliver master coils and collect slit coils without the logistics cost and transit time of moving material to and from other states. Local processing for local manufacturing — it's a simple efficiency that reduces both cost and risk.
Precision Requirements for Auto Stamping
Auto component press shops run progressive dies that are engineered to a specific strip width. The die pilot pins, feed steps, and blanking layouts are all designed around the slit width. Width variation outside the die designer's tolerance — even ±0.3mm on a tight die — causes parts to be stamped off-centre or pilot pins to fail to register.
At MVEE Industries, we process CR coil for auto applications with width tolerances appropriate to press shop requirements. We also verify camber — the lateral curvature of the slit strip — since camber causes strip tracking problems on coil feeders and ultimately misregistration on the die.
