From hot upset to ±0.025 mm post machining. One accountable owner from drawing to your US dock. Zero Section 301 tariffs on our China Plus One programs.
If you have ever sourced forgings 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 a forging program can cost you three weeks of production line downtime.
If you have ever sourced forgings 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 give that time back. Most forging programs need CNC machining, heat treatment, and surface finishing to get to your dock, and we run the whole chain under one owner. 33+ forging partner facilities across 22+ Indian cities, part of a 470+ facility audited partner network. Combined forging network capacity of 2,000 tonnes per month. One owner on your program from drawing intake through US dock delivery. Whether your monthly volume is 200 pieces or 20,000, we set up the program the same way.
I walk the press floor before a single PO is placed. We check press tonnage rating against the part footprint, billet preparation, induction heating uniformity, and the lab that will run your spectro analysis and mechanical tests. We pick partners who run heat treatment and CNC secondary operations under their own roof, on their own QA team, on their own clock. One roof, one floor, one accountable team for the full forging chain. DFM happens before a die is cut. T0, T1, and T2 validation gates come with photographic evidence, dimensional data, grain flow inspection, 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, shot count, and heat treatment cycle compliance. We track SPC on critical dimensions, hardness traverse data on every heat treated lot, and lot to lot consistency on critical fatigue zones. We send you a status report every Friday that covers WIP, NDT results, tooling health, and shipping milestones. Container loading photos reach your inbox before the seal goes on. Every lot carries a traceability ID from billet to your receiving dock. Nothing ships until the dimensional report and the NDT report both show green. We do not wait for you to ask. We report because that is how a forging 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.
A forging is not a casting with extra steps. The metal grain is aligned, not poured. The microstructure is verified, not assumed. Three controls separate a forging program that survives the field from one that ships the field a warranty claim.
Heat plus pressure aligns the metal grain along the load path. Cast metal has random grain. We verify alignment on first article using macro-etch per ASTM E381 because a forged knuckle that takes three times the fatigue cycles of a cast one is not a marketing claim, it is what keeps the part in the field for 250,000 miles.
Quench and temper. Normalize. Anneal. Case harden. Each cycle changes the steel inside, not just outside. We sign the cycle with the lab thermocouple log and a hardness traverse on the critical zone. Because a forging that left the press correct can leave the heat treat oven wrong, and the part will not tell you which one happened until it fails.
T0 first samples. T1 dimensional. T2 sign off. Each gate carries a checklist, photos of the cavity, and the shot sample side by side with the print. Because a die that runs without a gate review is a die that fails at shot 4,000, and we would rather catch it on the bench than on your line. NDT, MPI, and dimensional reports run on every production lot before it ships.
Closed die, open die, drop hammer, hot upset, and cold forging all run through the same VIA INDIGOS playbook. One owner from drawing to dock. One status update every Friday. One India network of 33 plus audited partner facilities behind every program.
The workhorse for steering knuckles, crankshafts, con rods, axle beams. Net shape with consistent grain flow along the load path. Tolerances from plus minus 0.4 mm as forged down to plus minus 0.025 mm post machining.
For shafts, blocks, rolls, and rings where the part is too big or the volume too low for closed die. Long lengths and heavy sections. Verified grain orientation through controlled draw and upset cycles.
Steam, air, or counterblow drop hammers for parts where impact energy and rapid deformation deliver better die fill on intricate geometries. Strong fit for hand tools, cutlery blanks, and aerospace fittings.
Headers, flange ends, valve stems, and bolt blanks. Localised heat and a horizontal forge upset the bar end into the die cavity. Material savings versus turning from bar stock are typically 30 to 50 percent.
Below recrystallisation temperature for tight tolerance and fine surface finish straight off the press. Common for fasteners, pinions, bearing rings, and hardware. Strain hardening adds strength without heat treatment for many alloys.
Three gates, three sign offs, photo evidence at every step. We do not move a die forward unless the gate before it is closed. A die that runs without a gate review is a die that fails at shot 4000, and we would rather catch it on the bench than on your line.
