CHALLENGES WE SOLVE
Medical Stamping Challenges & Our Solutions
Four recurring medical failure modes seen in incoming RFQs — and how each is prevented on our line.
01
Medical device components
The Challenge
Tolerance stack-up across progressive stages drifts critical features out of spec lot by lot.
Our Solution
Held with 0.005 mm positioning precision and 100% dimensional inspection before packing.
02
Sensor parts
The Challenge
Micro-shift under vibration and thermal cycling puts sensor alignment out of tolerance.
Our Solution
Vibration-critical positions verified on optical measurement with lot-level records.
03
Surgical and orthopedic instrument components
The Challenge
High-speed press wear shifts positioning precision before the first inspection catches it.
Our Solution
Scheduled die maintenance and in-process checks catch drift between lots, not after.
04
Implantable device parts
The Challenge
Spring-back on high-strength alloys pulls formed features away from the drawing.
Our Solution
Form spring-back characterized at FAI and compensated in the die before production.

Medical Device Progressive Stamping at High Volume
For the device parts we run — instrument hinges and jaw tips, contact springs, sensor diaphragms and lead-frame style terminals — the die, not the press count, sets the pace: progressive tooling with in-die sensing holds one station's misfeed from scrapping a coil. First-article reports, in-process dimensional checks and per-lot material certificates travel with each reel, so your incoming inspection and design-history-file paperwork pull from the same records we generated on the floor.
- High-speed progressive dies for medical device volumes
- In-house tooling designed for consistent, repeatable output
- Documented quality on every lot - the control medical demands
- Prototype to high-volume production support
Medical stamping
Stainless, Beryllium Copper and Burrs: The Medical Material Call
Medical device stamping is a materials decision before it is a die decision. SUS301 work-hardens into the spring temper that instrument hinges and contact fingers need; SUS304 covers general instrument bodies; SUS316L answers the chloride and sterilization exposure that 304 will not. For current-carrying contacts, C17200 beryllium copper holds spring force at low insertion force, and C5191 phosphor bronze is the cost-down when conductivity requirements allow. Thickness runs 0.05-3.0 mm on 21 presses, and the dimension that actually decides medical acceptance is edge quality: burr height on a 0.1 mm stainless part is a cleanliness risk inside the device, so every lot is checked on optical measurement against a defined burr spec, not just the dimensional print. Full batch traceability back to the coil, with material certificates on every shipment.
- SUS301 spring, SUS304 structural, SUS316L corrosion-critical grades
- C17200 beryllium copper and C5191 phosphor bronze for contacts
- Burr-height control verified on optical measurement per lot
- 0.05-3.0 mm coil stamping with lot traceability to the mill certificate

DFM & ENGINEERING SUPPORT
Design for Manufacturability for Medical
We review material, tolerance, bend and volume economics before tooling starts.
What We Review
Medical device components geometry
Feature walk-through — material formability, bend radii, tolerance stack-up and plating compatibility for this part.
Sensor parts geometry
Forming checks — springback take-up built into the die, minimum bend radius on the chosen temper, hole-to-edge distances held above tear-out limits.
Surgical and orthopedic instrument components geometry
Production checks — strip pitch and coil-set discipline on the feeder, in-die sensing on critical features, burr height under 0.05 mm at press speed.
Implantable device parts geometry
Assembly checks — mating-side datum features picked with the customer, flatness and coplanarity targets set for downstream automated assembly.
What Our DFM Review Checks
Bend radii
Inside radius held at R≥1.0t on spring tempers; tighter bends flagged for anneal or grade change before die design starts.
Holes & cutouts
Hole diameter ≥0.8t, pushed to 0.6t only with hardened punch steel; thin-gauge cutouts checked for tear-out.
Burr & edge quality
Burr height held under 0.05 mm so parts mate flat in assembly and plating adheres at the edges.
Tolerance & plating impact
Critical features piloted to ±0.005 mm; plating thickness (gold 2-8 µm, tin/zinc 5-12 µm) compensated in die design.
