Volume Production & Scalability — Reliable Batch Manufacturing of Sheet Metal Enclosures, Racks & Cabinets in India

Eterna Global Solutions LLP is built for recurring batch production, not one-off projects. Our factory layout, equipment, tooling systems, and production planning are designed so that once a product clears NPI and first-article approval, every subsequent batch runs faster, smoother, and more cost-efficiently than the last. Saved CNC programs are recalled in seconds. Dedicated stamping dies, welding jigs, and assembly fixtures are pulled from storage and mounted in minutes. Material is procured against a locked BOM from approved suppliers. The production team already knows the product — there is no learning curve on repeat orders.

This matters because most OEMs need consistent monthly or quarterly supply, not a single heroic delivery. A telecom operator rolling out 200 street cabinets over six months needs 30–40 units shipping every month, on schedule, at consistent quality. A data centre builder commissioning racks in phases needs batches of 50–100 units delivered to a specific dock on specific dates. An industrial OEM needs a steady stream of control enclosures feeding their own assembly line. In all these cases, the value of a manufacturing partner is not just the ability to make the product — it is the ability to make it again and again, on time, at the same quality and cost.

We handle production volumes from 25 to 500+ units per month per product, depending on product complexity and the mix of other programs running simultaneously. For OEM programs with predictable annual demand, we offer scheduled production with reserved capacity, material call-off agreements, and phased delivery to your style="color:var(--egs3-gold) !important; text-decoration:underline !important;">warehouse or installation sites across India.

What makes Eterna a volume production partner

Repeatable process • stored tooling • known product.

The difference between “can make” and “can keep making”

Many sheet metal shops can produce a good first batch. The test of a production partner is what happens on the fifth batch, the tenth, the twentieth. Does quality stay consistent, or does it drift because someone used different settings? Does lead time stay the same, or does it stretch because the shop is juggling too many ad-hoc jobs? Does the price hold, or does it creep up because material wasn’t booked in advance? Eterna is set up so that repeat production is easier and cheaper than first production — not the other way around.

Vertically integrated = no external bottlenecks

Because every manufacturing stage is under one roof, scaling production doesn’t require coordinating with external suppliers for sub-processes. We don’t wait for a third-party powder coater to schedule our job. We don’t depend on an outside welder’s availability. Our production schedule is controlled entirely by our own capacity, our own material inventory, and our own workforce — which means we can prioritise, flex, and respond to your volume needs without being at the mercy of someone else’s backlog.

Honest about capacity: We are a mid-scale contract manufacturer, not a mega-factory. Our strength is in the 25 to 500+ units per month range per product, with the flexibility to surge higher for simpler products or short-duration ramps. If your requirement is 5,000 identical enclosures per month indefinitely, we will tell you that upfront and help you find the right capacity. For the vast majority of OEM enclosure programs in India, our capacity is well-matched to real-world demand.

How repeat batch production works

From your PO to shipped product.
01

Purchase order received

Quantity • delivery date • delivery location confirmed

+

You issue a PO (or call-off against a blanket order) specifying the quantity, required delivery date, and ship-to location. Because the product is already in production status with an approved BOM and quality plan, there is no engineering review needed — the order goes straight to production planning.

  • Drawing revision confirmed — if you have issued an ECN since the last batch, the updated revision is verified before production starts
  • Any order-specific requirements noted (e.g., different RAL colour for this batch, specific serial number range, customer-branded labels for a new end-customer)
Repeat batch lead time: For an approved product with material available, typical repeat batch lead time is 3–5 weeks from PO, depending on batch size and product complexity. With advance material procurement against a forecast, this can reduce to 2–3 weeks production time. Simple products at smaller volumes can be faster; complex fully-integrated cabinets at large volumes may be slightly longer.

Production planning and scheduling

Capacity reservation • call-off • forecast-based procurement.

Scheduled production for recurring programs

For OEM programs with predictable monthly or quarterly demand, we establish a production schedule aligned to your delivery calendar. This means your order is planned into our production capacity before you issue the PO — not competing with other jobs for open slots when the PO arrives.

How it works: You share an annual or quarterly forecast (non-binding rolling forecast is fine). We plan production capacity and material procurement around that forecast. You issue call-off POs against the forecast as delivery dates approach. Production starts immediately because capacity and material are already in place. This reduces lead time, avoids supply gaps, and gives both parties planning visibility.

Blanket purchase orders: Some OEMs prefer issuing a blanket PO for the annual quantity with monthly call-off instructions. We accommodate either approach — individual POs or blanket with call-offs.

Managing multiple concurrent products

Our facility runs multiple product lines concurrently. A typical month might include batches of outdoor telecom cabinets for one OEM, server racks for another, and battery enclosures for a third — each at different production stages simultaneously.

Why this works: Different products are at different stages of the production flow at any given time. While one product’s panels are being laser-cut, another product’s frames are on the welding line, and a third product is in coating and assembly. The bottleneck in sheet metal production is rarely a single machine — it’s the coordination of the entire flow. Our production planning schedules each product through each stage so that machines and people are utilised efficiently without creating queues at any one process.

Dedicated tooling per product: Because each OEM program has its own stamping dies, welding jigs, and assembly fixtures, switching between products does not require re-engineering — only a tool changeover.

Communication: For active production programs, we provide order status updates at key milestones (material received, cutting complete, welding complete, coating complete, assembly and testing complete, ready for dispatch). You always know where your batch is in the production flow without having to chase us.

How volume reduces your per-unit cost

Material • setup • tooling • efficiency.

Material economics

Bulk material procurement: Larger production volumes allow us to order sheet metal in bulk quantities — full coils or full bundles rather than cut-to-size pieces from a stockholder. Bulk pricing is typically 5–10% lower per kg than small-lot purchases, and this saving passes directly to your piece price.

Nesting efficiency: Larger batch quantities produce better nesting yields because the software has more parts to pack onto each sheet. A 10-unit batch might yield 78% material utilisation; a 100-unit batch of the same part might yield 88% because remnants are minimised. Higher yield = lower material cost per part.

Scrap reduction: First-off checks and setup pieces are a fixed overhead per batch. In a 10-unit batch, 1–2 setup pieces represent 10–20% scrap. In a 200-unit batch, the same setup pieces represent under 1%.

Process and labour economics

Setup amortisation: Every production stage has a fixed setup time — loading the CNC program, mounting the die, setting up the jig, preparing the coating line. This time is fixed whether you’re making 10 units or 100. Larger batches spread setup cost across more units, directly reducing per-piece cost.

Stamping transition: At prototype and low-volume stages, parts are laser-cut (flexible but slower per piece). As volumes increase, transitioning high-run components to stamping slashes per-piece cost — a stamped bracket costs a fraction of the same bracket laser-cut, and cycle times drop from minutes to seconds. Our DFM team advises on the crossover point where tooling investment is justified by per-piece savings.

Learning curve: Production teams become faster and more efficient with each batch. Assembly time per unit typically decreases by 10–15% between the first and fifth batch as operators develop muscle memory and refine their workflow.

Transparent pricing: We break down our quotation into material cost, process cost, tooling cost (amortised or one-time), finishing cost, assembly cost, and delivery cost. This transparency lets you see exactly where cost sits and where volume leverage applies. If you can commit to higher annual volumes or longer-term agreements, we can sharpen pricing on the components where volume has the most impact.

Typical volume production scenarios

How OEMs use our production capacity.

Telecom network rollout

A telecom infrastructure OEM is deploying outdoor street cabinets across a region. Total requirement: 300–500 cabinets over 6–12 months. Delivery: 30–50 units per month to multiple installation sites across India. We manufacture ahead of the deployment schedule, hold finished inventory in our warehouse, and dispatch site-specific quantities per the rollout plan. Each cabinet is IP65 tested, electrically integrated, and branded with the OEM’s nameplates.

Data centre build-out
A data centre operator is commissioning server rooms in phases. Each phase requires 50–100 racks delivered to the data centre dock within a tight installation window. We manufacture complete batches per phase, palletise for forklift handling, and deliver on the specified dock date. 19″ rack rail alignment verified to EIA-310-E on every unit.

Industrial OEM production line

An industrial equipment manufacturer needs a steady supply of control enclosures (junction boxes, MCC panels, marshalling cabinets) feeding their own assembly line. Monthly requirement: 50–150 enclosures across 3–5 variants. We produce against a monthly call-off schedule, with finished units ready for collection or delivery by a fixed date each month. Each variant has its own tooling, BOM, and quality plan — running them concurrently is routine.

Energy storage / BESS deployment
A BESS integrator requires heavy-gauge battery enclosures in batches of 25–50 units, with strict quality documentation (full material traceability, serial-level inspection records, coating test certificates). Production is scheduled around the integrator’s project timelines, with lead times coordinated to match battery module availability so enclosures and batteries arrive at the assembly site together.

Flexibility across scenarios: These are representative patterns, not rigid categories. Some OEMs start with a small pilot order (10–25 units), validate the product in the field, and then ramp to recurring monthly production. Others place a large one-time order for a project deployment and return with a new product six months later. We accommodate both patterns — and the transition from pilot to volume is seamless because the same NPI process that qualified the first batch also set up the production infrastructure for all subsequent batches.
