Custom aluminum extrusion in 6063, 6061, 6005A, and 6082, held to ASTM B221 tolerances. Anodizing, powder coat, precision cut to length, and CNC machining on the same program. One accountable team from drawing to your US dock. India first, more regions as your volume grows.
VIA INDIGOS is a US contract manufacturing company that runs aluminum extrusion programs in India, as one accountable team from drawing to US dock. Die build, extrusion, aging, anodizing, machining, and packing sit under one program, with PPAP Level 3 on every part.
If you have ever sourced aluminum extrusions or profiles from anywhere in the world, you know the routine. Email at 9 in the morning. No reply. Email again at 4. Maybe an answer Tuesday. We built VIA INDIGOS so the fifth email never lands. Because one missed handoff on an extrusion program can cost you three weeks of production line downtime.
If you have ever sourced aluminum extrusions or profiles from anywhere in the world, you know the routine. Most buyers spend their week chasing updates instead of doing their real work. We built VIA INDIGOS to be the aluminum extrusion company that gives that time back. Most extrusion programs need CNC machining, anodizing, and die work to get to your dock, and we run the whole chain as one accountable team. 25+ extrusion partner facilities across 8 Indian cities, part of a 470+ facility audited partner network spanning 22+ cities. Press capacity from 600 to 3,500 tonnes across the network. One accountable team on your program from drawing intake through US dock delivery. Whether your monthly volume is 2,000 kilograms or 200,000, we set up the program the same way.
I walk the extrusion floor before a single PO is placed. We check press tonnage and billet size against the section, the die shop and its nitriding practice, the aging ovens, the anodize line, and the lab that will run your dimensional and film thickness checks. We pick partners who run extrusion, aging, machining, and finishing under their own roof, on their own QA team, on their own clock. One roof, one floor, one accountable team for the full aluminum chain. DFM happens before a die is cut. Die trial, first article, and PPAP validation come with photographic evidence, dimensional data, and a written verdict from our quality lead. Boots on the ground, every step of the way.
My team runs weekly checks on die wear, exit speed, temper results, and anodize film thickness. We track SPC on wall thickness and key dimensions, Webster hardness on every aged lot, and lot to lot consistency on color and finish. We send you a status report every Friday that covers WIP, inspection results, die health, and shipping milestones. Crate and container loading photos reach your inbox before the seal goes on. Every lot carries a traceability ID from billet cast number to your receiving dock. Nothing ships until the dimensional report and the finish report both show green. We do not wait for you to ask. We report because that is how an extrusion program should run.
Most contract manufacturers worldwide drop the ball at the handoff between two teams. We hold every one. Ten real stages, drawing to your dock. No sub-step skipped, no handoff left to chance.
8 extrusion cities. 25+ audited extrusion partners across direct extrusion, anodizing, powder coating, machining, and fabrication. Hover any marker to see partner count and what runs there.
8 extrusion cities · 25+ extrusion partners · 600T to 3500T press range
Most India sourcing is run from a laptop in Cincinnati. Ours is not. Our team is physically present at partner facilities for die trials, first articles, anodize and finish sign offs, and production launches. When something slips, we see it before you do. When quality holds, we have the photo evidence to prove it.
25+ qualified aluminum extrusion partner facilities across 8 Indian cities, inside a network that spans 22+. Real people on the floor making sure your drawing becomes an extruded aluminum profile that passes PPAP the first time.
If a metric does not have a name against it, a target, and a data source, it is not a metric. Below is the scoreboard we run on every extrusion program, refreshed weekly, surfaced in your Friday status email.
Follow one length of aluminum through the 5 stations that turn a heated billet into a finished component. All of it runs through one VIA INDIGOS playbook. One accountable team from drawing to dock. One status update every Friday. One India network of 25 plus audited partner facilities behind every program.
The press work. A billet heated to about 480 C is pushed through a steel die at 600 to 3,500 tonnes, then quenched, stretch straightened, and cut to mill length. Solid, semi hollow, and hollow sections up to a 250 mm circumscribing circle, walls down to 1 mm on 6063.
Gauged saw stops, deburring, and end machining hold cut length to +0/-1.5 mm standard and tighter on request. Lengths nest into your carton plan so the crate that arrives feeds the line without a resort, and the saw stop is re gauged after every blade change.
Drilling, tapping, punching, and milling on the profile so it ships as a component, not a raw bar. Fixtures hold the section without crush marks, and machined features run to plus minus 0.05 mm where the print calls it.
Anodized aluminum extrusions in clear, black, and color to MIL-A-8625 Type II, hardcoat Type III where the duty needs it. Film thickness measured per ASTM B244 on every lot, and color held to a signed range board so lot 40 matches lot 1.
Architectural powder to AAMA 2603 and 2604 with salt spray per ASTM B117 on file. Welding to AWS D1.2, hardware insertion, and sub assembly at the same partner, so brackets, frames, and enclosures arrive ready for your line.
Custom die vs standard catalog die vs CNC from solid vs roll formed vs formed sheet. Five honest comparisons, not marketing claims. Use this to short list before you send the drawing.
Your own section, recurring volume, low die cost.
Catalog shapes, fast start, no die wait.
Prototypes, 3D geometry a die cannot make.
Thin wall open sections at very high volume.
Flat and bent parts, holes and tabs, enclosures.
Three sign offs, photo evidence at every step. We do not move a die forward unless the sign off before it is closed. An extrusion die that runs past its nitride life is a die that puts lines down your show face, and we would rather catch it on the bench than on your line.
The die comes off the press after first trial. Fill, tongue deflection, and wall thickness checked against the print. Corrections cut, bearing polished, nitriding cycles and press hours logged on the die record, and the die pulled for polish before die lines ever reach your show face. The section is signed off on the bench before a production billet is heated.
The first production lengths off the corrected die. Full dimensional report on every callout. Twist, straightness, and flatness checked against ASTM B221 on a surface table. Webster hardness after aging, tensile to ASTM B557. Report to you before the next run.
PPAP Level 3 package complete. PSW signed by the buyer. Capability studies on critical features above Cpk 1.67. Lot traceability live to the billet cast number. Production releases only after the buyer has the full PPAP package in hand.
The right alloy and temper are half the part. We run 6063 aluminum extrusion alongside the other common 6000 series architectural and structural alloys, plus 6101 for busbar, in T4, T5, and T6 tempers set in controlled aging ovens. Below is the working range. A billet certificate travels with every lot so the cast number traces back to the part.
| Alloy | Common tempers | Typical strength | Key properties | Typical parts |
|---|---|---|---|---|
| 6063 | T5, T6 | 186 to 241 MPa | Extrudes clean, anodizes bright, best surface | Window and door profiles, trim, heatsinks |
| 6061 | T4, T6 | 241 to 310 MPa | Structural strength, machines and welds well | Frames, machine bases, structural sections |
| 6005A | T5, T6 | 260 to 296 MPa | Near 6061 strength with better extrudability | Rails, ramps, ladders, structural tube |
| 6082 | T5, T6 | 270 to 310 MPa | Highest strength of the common 6000 series | Load bearing sections, transport, marine |
| 6060 | T5, T6 | 160 to 215 MPa | Thin walls and complex sections run clean | Complex thin wall profiles, LED housings |
| 6101 | T61, T6 | 57% IACS min | High electrical conductivity for power | Busbars, conductors, electrical hardware |
Other alloys and tempers extruded on request. Section range depends on press size and circumscribing circle. We confirm alloy, temper, and finish during DFM review before quote, and the billet certificate goes in the PPAP file.
Upload your drawings. We review, run DFM, and return a full landed cost breakdown with tooling timeline and PPAP scope. You get one contact from intake to ship.
Every industry has its own certs, its own regulatory pressure, its own drawing conventions. The handoff discipline stays the same. What changes is the technical documentation that moves with the part.
Plain English answers, written for procurement and engineering teams who want a real number, not a brochure. Last reviewed by Mandeep Singh in August 2026.
A die for a solid section runs 2 to 4 weeks from PO to first trial. Hollow and semi hollow dies run 4 to 6 weeks. First article off the corrected die lands in 4 to 7 weeks from PO. That is the quiet advantage of extrusion over stamping or molding: the die costs hundreds to a few thousand dollars, not tens of thousands, so a custom section pays for itself early.
If a supplier quotes 1 week on a hollow die, ask whether that includes nitriding, the corrected second trial, and the dimensional report. It usually does not.
PPAP Level 3 means we send the buyer the full Production Part Approval Process package: signed PSW, design records, dimensional report on every callout, material test reports on the billet, capability studies with Cpk on critical features, MSA on the inspection method, control plan, PFMEA, and the appearance approval report when finish is a callout.
Production does not release until the buyer has the package in hand and the PSW is signed. That is the discipline. No PPAP, no shipping.
The 6000 series workhorses: 6063 and 6060 for surface finish and complex thin wall sections, 6061 and 6082 for structural strength, 6005A between them, and 6101 for busbar conductivity. Tempers T4, T5, and T6, set in controlled aging ovens and verified by Webster hardness and tensile testing to ASTM B557.
Sections run up to a 250 mm circumscribing circle with walls down to 1 mm on 6063. Tell us the alloy and section and we confirm extrudability during DFM review.
For custom die programs, our partners typically run 250 to 500 kg per section per release, since the press is scheduled by billet. Below that, a standard catalog die usually makes more sense, and we run those from 100 kg per release.
Tell us the section weight per meter and the annual volume, and we tell you the run size that makes the price work.
Standard profiles run to ASTM B221 tolerances, roughly plus minus 0.15 to 0.25 mm on small cross section dimensions and wider as the section grows, with precision class available on request. Cut length holds +0/-1.5 mm standard and tighter on request. Machined features run to plus minus 0.05 mm where the print calls it.
If a print calls machining grade tolerances on an as extruded face, we flag it at DFM and quote the CNC step honestly instead of promising the die can do it.
Default is FOB Nhava Sheva or CIF US West Coast. We offer DDP on request with a logistics markup that we disclose up front. Inbound preferences are Los Angeles, Long Beach, New York, Newark, and Chicago, with alternates only when they improve lead time or cost.
For programs with US warehouse pull, we hold inventory and ship JIT to your dock. Storage and handling fees on a published rate card.
You do. Die ownership transfers to the buyer on full payment, in writing, with a die record that documents die ID, press hours, nitriding cycles, correction history, and storage location. We hold the die at our partner facility on a bailment basis, available for inspection or transfer at any time.
If you want to move programs in 18 months, the die is yours. We do not lock dies to facilities or hold them hostage.
Send us your drawings and judge us as your aluminum extrusion supplier on the reply. You get a full landed cost breakdown, a die timeline, the recommended extrusion route, and a PPAP scope. One contact from intake to ship. No commitment required.
