Stamping Parts | Custom Metal Stamping Service & Quote

Most buyers who ask us for a metal stamping services quote already know what they want on the drawing, but they have not decided which supplier can actually hold it. The honest answer is that a stamped part is only as good as the die that cuts it, the press that runs it, and the inspection that proves it. We have been stamping production parts in Wenzhou since 1991, and we run 40 stamping presses from 25 tons to 400 tons on a single shop floor backed by in-house tool making. This page explains how we quote, what tolerance class we can hold, and which drawings are worth sending.

Send your STEP or DXF and a 2D drawing with GD&T to our quoting form, or message us on WhatsApp at +86 188 6828 5255. We respond inside 24 hours with a metal stamping services quote that includes material, tooling amortisation, finish, and inspection.

Common Applications for Stamped Parts

Custom metal stamping shows up wherever a flat coil or sheet has to become a feature part at volume. The four areas we run most often on our press line:

• Electrical contacts and terminals: progressive-die stamped copper alloy parts for connectors, relays, and EV charging pins. Material is typically C11000, C26000 brass, or C52100 phosphor bronze in strip 0.1 mm to 1.0 mm thick.
• Automotive brackets and busbars: SPCC, SECC, SUS304, and aluminum 5052 brackets from 0.5 mm to 3.0 mm. These parts run into the millions per year on progressive dies with in-line measurement.
• Battery and EV cell components: battery tabs, cell spacers, and busbars for traction battery packs. Most run in 1060 aluminum or nickel-plated copper, often with hairpin bends and tight hole-to-hole positions.
• EMI shields, springs, and precision shims: thin metal stamping from 0.1 mm to 0.3 mm in SUS301, C17200 beryllium copper, and phosphor bronze. Burr control is the entire game at that thickness.

Manufacturing Support from VOLCRIX

When a stamping drawing lands on our engineering desk, we look at four things before we send a metal stamping services quote:

• Tooling method: single-station die, progressive die, or deep draw. The answer depends on annual volume, feature count, and material thickness. Progressive dies cost more up front but amortise fast at volume; single-station dies are right for prototype runs and parts with a single bend or pierce.
• Material grade and thickness: SPCC, SECC, SUS304, SUS301, 5052, 6061, C11000, C26000, C52100, C17200, and their spring-temper conditions. We stock common grades and pull from certified mills for the rest.
• Tolerance class: ±0.1 mm commercial, ±0.05 mm precision, ±0.01 mm high-precision progressive die. The class on the drawing drives tooling cost and inspection depth, and it is the first thing we look at when reviewing feasibility.
• Surface finish: bare, tin plating, nickel plating, zinc plating, anodising, powder coating, or passivation. Finish goes on the quote as a separate line because it drives both cost and lead time.

All four of those decisions get rolled into the metal stamping services quote we send inside 24 hours, and the engineer who reviewed the drawing signs off on the numbers.

Buyer Checklist Before You Request a Metal Stamping Services Quote

Most of the back-and-forth on a new stamping part comes from missing information on the drawing. Before you ask for a quote, make sure these four items are clear:

• 2D drawing with GD&T and a 3D model: STEP, IGES, or X_T. Tolerances, datums, and the surface finish callout must be on the drawing, not just in the email body.
• Material grade and temper: SPCC 1.0 mm, SUS301 1/2H 0.3 mm, 6061-T6 1.5 mm. If you do not specify, we will default to the most common grade for the application and flag it in the quote.
• Annual volume and prototype quantity: this drives the tooling method. 5,000 pieces per year almost never justifies a progressive die; 500,000 pieces per year almost always does.
• Critical features and inspection requirements: burr height limits, flatness, hole-to-hole position, surface roughness, plating thickness. If a feature matters, it must be on the drawing with a tolerance and a measurement method.

Authority Summary

VOLCRIX runs an ISO 9001 and IATF 16949 certified shop floor. Incoming material is verified on a spectrometer, critical dimensions are checked on a Zeiss CMM, and surface finish and plating thickness are tested in our in-house lab. Every shipment leaves with an inspection report — first article inspection for new parts, in-process checks at defined intervals, and final dimensional reports on every lot. If a part is safety-critical or destined for a Tier 1 automotive line, we support PPAP and AS9102 documentation without adding lead time.

Frequently Asked Questions

What is the standard tolerance for stamped parts?

Standard stamped parts run to ±0.1 mm on most dimensions, precision stamped parts hold ±0.05 mm, and high-precision progressive die stamping can hold ±0.01 mm on critical features. The tolerance class on the drawing drives tooling cost and inspection depth, so it should be specified per feature rather than blanket-stated.

How fast can I get a metal stamping services quote?

Most metal stamping services quotes go out inside 24 hours when the drawing, 3D model, material grade, and annual volume are clear. Complex parts with tight GD&T or unusual finishes may take 48 hours because the engineer needs to walk the die design before pricing. Samples typically run 7 to 15 days after quote approval, and production lead time is 3 to 4 weeks.

Do I need a progressive die or a single-station die?

Annual volume, feature count, and tolerance class drive the decision. Single-station dies are right for prototype runs and simple parts with one or two features. Progressive dies are right for high-volume parts with multiple features and tight tolerance, because each station performs one operation on the strip as it indexes through. As a rough rule, parts running more than 50,000 pieces per year usually justify a progressive die on the second or third production cycle.

What is the smallest thickness you can stamp?

Thin metal stamping handles 0.1 mm to 0.3 mm material routinely. Below 0.1 mm, the strip wrinkles and tears during feeding, and burr control becomes impossible. Die clearance at that scale is roughly 5-8% of material thickness per side, so a 0.1 mm part runs around 0.006 mm clearance per side. That is precision tool work and it is one of the things our shop floor is set up for.

Why VOLCRIX for Precision Manufacturing

VOLCRIX is a Wenzhou-based precision manufacturing facility that has run one-stop metal and plastic part production since 1991. Our shop floor holds more than 60 Star Swiss turning machines, 40 stamping presses, 20 injection molding machines, and 60 spring coiling machines, all tied together by a single quality system.

Every batch is verified on a Zeiss coordinate measuring machine, and a spectrometer checks incoming material chemistry on every coil and bar we receive. Surface finish, plating thickness, and hardness are tested in our in-house lab, and every shipment leaves with an inspection report. Our quality system is certified to ISO 9001 and IATF 16949, which is the same standard automotive Tier 1 suppliers run under.

We do not hide behind buzzwords. When a buyer sends a 3D model and a 2D drawing, our engineer reviews tolerances, callouts, and material grade before quoting, and we tell you on the first reply if a dimension is at risk or if a feature needs a small design change to be producible. That conversation is what separates a supplier that ships parts from one that ships risk.

Quoting turnaround is 24 hours for most RFQs, sample turnaround is 7 to 15 days depending on complexity, and production lead time after sample approval is typically 3 to 4 weeks. We support both small prototype runs and high-volume production, with no minimum order quantity on engineering samples and volume pricing that scales with annual usage.

How We Hold ±0.01 mm on Production Stamping

Talking about tolerance is one thing; proving it on the production floor is another. Here is what we actually do at VOLCRIX when a drawing calls for ±0.01 mm on a critical dimension.

First, the die is built in our in-house tool room. We use carbide punches and dies for production runs over 100,000 pieces, and high-grade tool steel (SKD11, DC53) for shorter runs. Punch and die clearances are measured with a pin gauge set, and the die is then tryout on a 25-ton or 40-ton press with a strip of the actual production material. First articles are inspected on a Zeiss CMM, and if a feature is running out of tolerance we adjust the die before the production run starts.

During production, the press runs with a part sensor on every critical station, and the strip is piloted at every progressive die station so the strip does not drift. We pull in-process dimensional checks every 2 hours or every 500 pieces, whichever comes first, and the data is logged against the lot number. Burr height is checked with a burr gauge at the same interval, and the operator records the value on the traveler.

Material variation is the wild card. A 1.0 mm SPCC coil from a major mill runs 0.98 to 1.02 mm, and that range is enough to push a blank dimension out of spec if the die was sized for nominal. Our process engineers review the mill cert on every coil lot, and they adjust the feed or the die clearance for lots that run thick or thin. That step alone eliminates a class of dimensional rejects that other suppliers never catch.

Typical Tolerance Stack-Up on a Stamped Part

A stamped part rarely has a single critical dimension. It usually has a stack of features that all have to come together: a hole diameter, a bend-to-hole distance, a flatness over a defined area, and a surface roughness. Each one is controlled by a different process variable, and the supplier has to manage them all at once.

• Hole diameter: controlled by punch and die clearance, material thickness, and burr height. ±0.01 mm is achievable on progressive dies with carbide tooling and ground clearances.
• Bend angle and bend-to-hole distance: controlled by press brake accuracy, springback compensation, and material lot variation. High-strength steel and aluminum spring back aggressively; overbend or coining is needed in the die to hit the angle.
• Flatness over a defined area: controlled by residual stress in the strip, press parallelism, and part handling. A precision level on a granite table is the standard way to check it.
• Surface roughness: controlled by die surface finish, lubrication, and material grade. Ra 0.8 μm is typical for precision stamping; Ra 0.4 μm is achievable on polished dies.
