OEM Contract Manufacturing — White-Label Sheet Metal Enclosure Production for Original Equipment Manufacturers in India

Eterna Global Solutions LLP is a contract manufacturer of precision sheet metal enclosures, server racks, telecom cabinets, battery housings, and custom fabricated assemblies for Original Equipment Manufacturers (OEMs) across data center infrastructure, telecommunications, energy storage, power distribution, industrial automation, and defence electronics sectors. We manufacture your product, to your design, under your brand — delivering fully finished, tested, and installation-ready units from our vertically integrated facility in Noida, India.

What makes Eterna a contract manufacturing partner rather than a component supplier is vertical integration. Every manufacturing stage — design & DFM engineering, CNC laser blanking, stamping, press-brake forming, welding & fabrication, powder coating, electrical integration & assembly, IP testing, and warehousing & logistics — happens under one roof. You issue a single purchase order and receive a finished product. No multi-vendor coordination, no finger-pointing between suppliers, no quality gaps at handoff points.

We serve OEMs who need a reliable, scalable manufacturing partner that can handle the full production cycle: from engineering review of your drawings through first-article approval, batch production, quality inspection, IP testing, branded packaging, and PAN-India or export delivery. Whether you are a global equipment company looking for a production partner in India, or an Indian OEM building your own product line, Eterna provides the manufacturing backbone so you can focus on design, sales, and deployment.

Why OEMs choose Eterna as their contract manufacturer

Vertical integration • single vendor • zero handoff gaps.

The problem with fragmented supply chains

Most OEMs building sheet metal enclosures in India deal with 3–5 separate vendors: one for laser cutting, another for bending, a third for welding, a fourth for powder coating, and a fifth for assembly. Each handoff introduces transit damage risk, scheduling delays, and quality gaps. When a door doesn’t fit the frame, the powder coater blames the welder, the welder blames the bender, and you’re left chasing three vendors to find the root cause. Meanwhile, your customer’s deployment schedule slips.

Eterna’s single-vendor model

At Eterna, every process is under one roof. Raw sheet metal enters our facility, and a finished, coated, assembled, IP-tested, packaged enclosure leaves it. There is exactly one vendor to manage, one quality system to audit, and one team accountable for delivery. If something goes wrong — a tolerance issue, a colour mismatch, a late shipment — there is no vendor to blame except us, and we fix it immediately because every person involved in the fix is in the same building. This is the core value proposition of contract manufacturing with Eterna.

Designed for OEM relationships

We understand how OEM partnerships work. Your product specifications, drawings, and BOM are treated as confidential intellectual property. We manufacture exclusively to your design — we don’t sell your product under our name or share your designs with other customers. Production tooling (stamping dies, welding jigs, assembly fixtures) built for your program is dedicated to your exclusive use and stored securely at our facility. Your product is your product — we provide the manufacturing capability.

Scale without capital investment

Building an in-house sheet metal manufacturing line requires significant capital investment: fiber lasers, CNC press brakes, welding stations, powder coating lines, assembly infrastructure. By partnering with Eterna, you gain access to all of this without any capital expenditure. You convert fixed manufacturing overhead into variable per-unit cost, freeing your capital for product development, sales, and market expansion. And you can scale production up or down without the burden of factory capacity sitting idle during low periods.

For procurement and engineering leaders: Eterna is not a broker or trading company. We are a direct manufacturer with our own factory, our own machines, and our own workforce. When you visit our facility, you will see your product being cut, bent, welded, coated, and assembled on our floor by our people. That’s what separates a contract manufacturer from a middleman.

OEM engagement models (click to expand)

Build-to-print • build-to-spec • turnkey • kitting.
Flexible engagement: These models are not rigid categories. Most OEM relationships evolve over time — starting with build-to-print for an existing product, then moving to build-to-spec for the next generation, then expanding to turnkey for a new product line. We adapt to your needs as the partnership grows.

Industries and OEM sectors served

Telecom • data centre • energy • industrial • defence.

Telecommunications

Outdoor street cabinets, BTS enclosures, fibre distribution hubs, small-cell pole-mount enclosures, and equipment shelters for telecom operators and network infrastructure OEMs. IP55–IP66 rated, powder coated (RAL 7032 standard), with thermal management and power distribution integration. We understand telecom deployment realities: remote sites, harsh weather, monsoon exposure, and the need for field-swappable modules.

Data Centre Infrastructure
19″ server racks (9U–47U), hot/cold aisle containment frames, in-row cooling enclosures, power distribution cabinets, and cable management systems for data centre builders and IT infrastructure OEMs. Manufactured to EIA-310-E rack standards with precision rail alignment, high cable capacity, and powder coat finish in RAL 7035 (light grey) or RAL 9005 (jet black).

Energy storage & power distribution

Battery Energy Storage System (BESS) enclosures, EV charging station cabinets, solar inverter housings, UPS enclosures, and power distribution panels. Designed for thermal management, fire safety compartmentalisation, and outdoor IP-rated deployment. RAL 7016 (anthracite grey) standard for battery enclosures.

Industrial automation & control
Motor control centres (MCCs), PLC enclosures, operator interface panels, junction boxes, and marshalling cabinets for factory automation, process control, and industrial equipment OEMs.

Defence & aerospace electronics
Ruggedised equipment enclosures, transit cases, and electronic housings for defence system integrators. Manufactured to tight tolerances with full material traceability and documentation per defence procurement requirements.

Sector-agnostic manufacturing: Sheet metal fabrication processes are the same regardless of which industry the product serves. What changes is the specification (IP rating, material grade, tolerance class, finish, testing, documentation). We manufacture to the specification you provide — whether it’s a telecom cabinet destined for a cell tower or a defence enclosure going on a military platform.

How an OEM contract manufacturing engagement works

From first enquiry to recurring production.
01

RFQ and technical review

Drawings reviewed • DFM feedback • commercial proposal

+

You share your product drawings (or specifications), target volumes, delivery locations, and quality requirements. Our engineering team reviews the design for manufacturability and prepares a detailed proposal.

  • DFM review identifies potential manufacturing issues, cost-saving opportunities, and any specification clarifications needed before quoting
  • Commercial proposal includes: material cost, process cost, tooling cost (if applicable), finishing cost, assembly/integration cost, packaging cost, and delivery cost — broken down transparently
  • Lead time estimate for first-article and batch production provided with the quote
  • NDA signed before drawing exchange if required by your procurement policy
Time to first delivery: For a new product with moderate complexity (e.g., 42U outdoor telecom cabinet), typical timeline from drawing receipt to first production delivery is 6–10 weeks, including DFM review, sample build, first-article approval, tooling, and first batch. Repeat batches typically ship 3–5 weeks from PO.

White-label and OEM branding

Your brand • our manufacturing • fully branded output.

What white-label manufacturing means

White-label (or private-label) manufacturing means Eterna produces the product, but the product carries your brand identity — not ours. The end-customer sees your brand name, your model number, your logo, and your documentation. They never know (or need to know) that the product was manufactured by Eterna. This is standard practice in OEM contract manufacturing and is how many leading equipment companies operate globally — designing and marketing the product while outsourcing production to specialised manufacturing partners.

Branding elements we apply

Nameplates and labels: Screen-printed or laser-etched aluminium nameplates with your company logo, model number, serial number, electrical ratings, and certification marks — affixed per your placement drawing.

Adhesive labels and stickers: Barcode labels, QR codes, asset tags, safety labels, and product identification stickers applied per your specification.

Silk-screen printing: Direct screen print of logos and text on powder-coated surfaces for a permanent, professional brand presence.

Packaging: Branded outer cartons, branded packing slips, and customer-specific packaging tape — so even the unboxing experience reflects your brand.

Documentation: Your branded installation manuals, warranty cards, and quality certificates included inside the packaged product.

Confidentiality: We sign NDAs as standard practice. Your product designs, customer list, pricing, and production volumes are strictly confidential. We do not display or reference your products in our marketing without your written permission. Your competitive advantage in the market stays protected.

Quality assurance and compliance for OEM programs

Process control • traceability • documentation.

Quality system

Product-specific quality plans: Every OEM program has a dedicated quality plan defining inspection points, acceptance criteria, sampling rates, and documentation requirements. This plan is developed during the first-article phase and maintained under revision control.

In-process inspection: Quality checkpoints at each manufacturing stage (post-blanking, post-forming, post-welding, post-coating, post-assembly) catch issues at the source rather than at final inspection when rework is more costly.

Final inspection: 100% visual and functional inspection on every unit. Dimensional sampling per AQL as agreed with the customer, or 100% for critical dimensions.

IP testing: 100% of IP-rated cabinets water-tested in-house per IEC 60529 before dispatch. Not sample-based — every unit tested.

Traceability and documentation

Serial-number traceability: Every assembled unit carries a unique serial number traceable to production order, material batch, assembler ID, inspector sign-off, and test results.

Material test certificates: Incoming raw material verified against specification. Mill test certificates (MTCs) retained and available for customer audit or shipment documentation.

Shipment documentation: Packing list, inspection report, coating test results, IP test certificate, and material traceability — provided per customer requirements as part of the standard delivery package.

Customer audits: Our facility is open for customer audits, factory visits, and process reviews. We welcome due diligence — it builds confidence and strengthens the partnership.

Continuous improvement: Production data (reject rates, rework incidence, on-time delivery) tracked and reviewed to drive quality improvements across recurring programs.

Compliance note: We manufacture to customer-specified standards. Common standards applied across OEM programs include: IS/IEC standards for enclosures, EIA-310-E for 19″ rack rail spacing, IEC 60529 for IP ratings, AWS D1.3 for sheet metal welding, ISO 2409 and ISO 1519 for powder coating adhesion and flexibility. If your product requires compliance with specific certifications, inform us during the RFQ stage so we can incorporate the requirements into the quality plan.
