Custom Sheet Metal Parts & Precision Stamping | VOLCRIX Manufacturing
Direct answer: VOLCRIX manufactures custom sheet metal parts through progressive die stamping, deep drawing, and four-slide forming for OEM buyers in automotive, electronics, EV charging, and industrial applications. We produce metal stamping components from stainless steel, cold-rolled steel, aluminum, copper, and brass in thicknesses from 0.1 mm to 6.0 mm, with tolerances held to ±0.05 mm and full FAI inspection on a Zeiss CMM. Our factory runs 40 stamping presses from 25 tons to 630 tons, and we ship to 500+ customers across 40+ countries.
If a buyer sends a sheet metal drawing with a tonnage spec, a bend sequence, and an annual volume, the answer is usually not “what machine do we use” — it is whether the part should be stamped, deep-drawn, laser-cut-and-bent, or four-slide formed. Each process has a sweet spot in thickness, geometry, and volume. This guide walks through how VOLCRIX routes a sheet metal drawing to the right process and the design decisions that drive the quote.
On a real production quote, four things determine the final per-piece cost more than any other factor. Material utilization on the strip layout, total tonnage required across forming stations, the number of secondary operations needed after stamping, and plating or finishing throughput. A drawing that looks simple can be expensive to produce if any of those four are out of balance. The DFM review we run before quoting catches the worst of these — usually within 24 hours of receiving the drawing.
Common Applications of Sheet Metal Stamping
- Automotive chassis stamping parts. Structural brackets, reinforcement plates, seat belt anchors, EV battery tray components, and suspension-related stampings. These parts typically run in carbon steel (DC04, SPCE) or HSLA at 1.0–3.0 mm thickness and ship in lots of 50,000 to 1,000,000 pieces per year.
- Electrical contacts and stamped electrical connectors. Precision stampings for plug-in terminals, battery contacts, EMI shields, and grounding clips. Brass C2600, C2680, and copper C11000 are common; thickness is typically 0.2–0.8 mm; tolerances to ±0.03 mm on critical features.
- EV battery busbars and stamped lead frames. High-current copper or aluminum stampings for battery pack interconnects, fuse terminals, and power module lead frames. Material is typically C11000 copper or 1060 aluminum; plating is tin or nickel for solderability.
- Industrial enclosures and EMI/RFI shields. Two-piece stamped shields for sensitive electronics, plus custom enclosures for industrial controllers. Material is typically SECC, SGCC, or stainless 304; thickness 0.3–1.5 mm.
- Replacement and aftermarket parts. Replacement metal stamping parts for legacy automotive, appliance, and industrial equipment lines. We reverse-engineer from samples, produce sample runs, and hold tooling for 5+ years for service parts.
Manufacturing Support from VOLCRIX
- Progressive die stamping from 25 to 630 tons. VOLCRIX runs 40 stamping presses — from small high-speed presses for connector pins to 630-ton large-tonnage presses for automotive chassis stampings. Tooling is built in-house on our wire EDM and CNC milling centers.
- Deep drawing for cylindrical and box-shaped parts. Multi-stage deep draw dies for motor housings, sensor cans, and battery cell housings. Maximum draw depth of 200 mm on cups up to Ø300 mm.
- Four-slide forming for wire and strip components. Four-slide machines produce spring clips, contacts, and flat-formed parts from wire or strip up to 6.0 mm wide. Complex bends and compound angles are achievable in one machine cycle.
- In-house tool & die design with 3D simulation. AutoForm and DFM reviews on every new stamping to predict splits, wrinkles, and springback before tool steel is cut. Average lead time for new tooling is 4–6 weeks.
- Plating, passivation, and coating coordination. Tin, zinc, nickel, tin-nickel, and powder coating are managed through qualified sub-processors with full incoming inspection on plating thickness and adhesion.
Sheet Metal Stamping Buyer Checklist
- Mark all critical dimensions in the drawing — bend angles, hole-to-edge distances, hole-to-bend distances, and cosmetic zones. Bend angles are ±1° achievable on standard tooling; tighter tolerance requires a bend-and-check fixture. Hole-to-edge should be ≥1.5× material thickness; hole-to-bend should be ≥2× material thickness plus the bend radius.
- Specify material grade and temper, not just “steel” or “stainless.” “Stainless steel” can mean 304, 316, 430, or 17-4PH — each has different formability, springback, and pricing. VOLCRIX quotes against ASTM or EN material designations.
- Confirm whether the part will be plated, painted, or left as mill finish. Plating thickness (typically 5–20 µm for tin or zinc) changes hole and slot tolerances by 10–40 µm per surface. If the drawing says “after plating,” tolerances are typically ±0.05 mm; if “before plating,” they can be tighter.
- Specify annual volume and target unit price. A drawing with 50,000 pieces per year routes to a different press and die set than 5,000,000 pieces per year. Volume drives whether the tooling is justified for hard tooling or whether a soft-tool prototype run is appropriate.
- For high-volume progressive stamping for automotive components, review the strip layout before tool build. Progressive die layout determines material utilization, tonnage requirements, and gate / pilot location. A 5% material utilization improvement on 1000 tons of steel per year saves real money.
Across our automotive stamping programs, three failure modes have shown up on customer lines that we now flag at the RFQ stage. First, burr height exceeding 5% of material thickness on a cut edge — usually a clearance or wear issue on the die that we catch during in-process inspection. Second, springback on HSLA340 and similar high-strength steels — predicted by AutoForm and corrected in the die tryout. Third, plating thickness drift on long production runs — controlled by XRF sampling every 500 pieces and a tool-tight plating chemistry spec. Each of these is preventable with the right upfront conversation.
For Tier 1 automotive buyers, our DFM review includes material utilization, tonnage per station, secondary operations, and plating flow — typically within 24 hours of receiving the drawing. We also share strip layout sketches and risk callouts before tooling is cut, so engineering decisions are visible to both sides before any steel is burned.

Frequently Asked Questions About Sheet Metal Stamping
What is the difference between progressive die stamping and deep drawing?
Progressive die stamping feeds flat strip through a sequence of stations that cut, bend, and form the part progressively. Deep drawing uses a punch and die to draw flat sheet metal into a cup or box shape. Progressive die is ideal for flat or shallow formed parts in high volume; deep drawing is ideal for cylindrical or box-shaped parts with depth.
What materials can VOLCRIX stamp?
Cold-rolled steel (SPCC, DC04), stainless steel (304, 316, 430), hot-dip galvanized (SGCC, SECC), aluminum (5052, 6061-T6, 1060), copper (C11000, C18150), brass (C2600, C2680, C3604), and pre-plated materials. Material thickness from 0.1 mm to 6.0 mm standard; up to 8.0 mm on heavy-stamping presses.
What is the typical lead time for new sheet metal tooling?
Standard lead time is 4–6 weeks for new progressive die tooling, including design review, tool steel cutting, CNC machining, wire EDM, assembly, and tryout. Lead time depends on die complexity — a single-station die can be 2–3 weeks; a 10-station progressive die is 6–8 weeks.
What tolerances can VOLCRIX hold on sheet metal stampings?
Standard tolerance is ±0.10 mm on linear dimensions and ±0.05 mm on critical features. Tight tolerance of ±0.03 mm is achievable with precision dies and in-process inspection. Bend angles are ±1° standard, ±0.5° on bend-and-check tooling.
Can VOLCRIX handle prototype runs before committing to hard tooling?
Yes. We offer soft-tool prototype runs using laser cutting, CNC bending, and four-slide forming for quantities under 1,000 pieces. For 1,000–10,000 piece runs, we often use a hardened short-run die on a manual or servo press before committing to full progressive tooling.
What surface finishes are available on stamped sheet metal parts?
Mill finish, deburred, vibratory finished, tumble-finished, electroplated (tin, zinc, nickel, tin-nickel, gold), powder-coated, e-coated, wet-painted, anodized (aluminum only), and passivated (stainless only). Plating thickness is verified on XRF gauges; cosmetic surfaces are inspected under controlled lighting per AQL sampling.
Does VOLCRIX supply metal stamping components for the automotive industry?
Yes. VOLCRIX is IATF 16949 certified and ships automotive chassis stamping parts, EV battery tray stampings, seat belt anchors, reinforcement plates, and structural brackets to Tier 1 and Tier 2 automotive suppliers. We support PPAP documentation, IMDS material declarations, and customer-specific quality clauses.
What is the difference between a metal stamping components supplier and a fabricator?
A metal stamping components supplier produces parts via high-tonnage progressive or transfer dies for high-volume OEM programs — typically IATF 16949 or ISO 9001 with PPAP documentation. A fabricator typically does laser cutting, CNC bending, and welding for low-volume or prototype runs. VOLCRIX does both under one roof, with progressive die stamping as the core capability.
