Why “Simple” Small Stamping Parts Always Cause Assembly Nightmares
Small parts create the biggest headaches. When you order millions of small electrical contacts, retaining clips, or micro-brackets, you assume consistency. But if your supplier’s stamping die wears out after 10,000 hits, the remaining 990,000 parts will have dimensional drift, severe burrs, and weak structural integrity.
The High-Volume Trap:
Job shops bid low because they use cheap D2 steel for their stamping dies instead of premium Tungsten Carbide. They do not maintain their presses, resulting in uneven pressure. The outcome? A 15% scrap rate on your assembly line because the parts literally do not fit.
Our QC operators inspect small stamping parts under magnification to ensure absolute edge cleaniness and micro-dimensional accuracy.
The 4 Fatal Flaws in Small Stamping Procurement
Whether you are sourcing micro-shields for PCBs, battery contacts, or structural micro-clips, here are the defects we help OEMs eliminate:
❌ 1. Severe Edge Burrs
The Problem: Dull stamping dies tear the metal instead of shearing it, leaving sharp micro-burrs that slice wires and ruin gaskets.
Our Solution: Tungsten Carbide progressive dies combined with specialized vibratory tumbling to achieve perfectly smooth, safe edges.
❌ 2. Dimensional Drift
The Problem: Part #1 is perfect, but Part #50,000 is 0.2mm too long because the supplier did not perform die maintenance.
Our Solution: Automated in-line optical inspection and strict die maintenance schedules every 500,000 strokes.
❌ 3. Metal Thinning on Bends
The Problem: The die design forces the metal to stretch too much during forming, creating weak points that snap under tension.
Our Solution: Advanced DFM simulation software to predict material flow and optimize the bend radius before tooling begins.
❌ 4. Oxidation & Poor Plating
The Problem: Small parts arrive stuck together, rusted, or with uneven zinc/nickel plating due to cheap bulk-barrel processing.
Our Solution: Centrifugal drying, rust-preventative oils, and premium rack/barrel plating for uniform coverage.
Our progressive stamping presses can produce millions of small, complex parts per month with zero dimensional variation.
| Production Spec | Generic Job Shops | MSTFab OEM Standard |
|---|---|---|
| Tooling Material | Cheap D2 Steel (Wears out quickly) | Premium Tungsten Carbide for millions of flawless cycles. |
| Tolerance Control | +/- 0.2mm | +/- 0.02mm for micro-electronic and automotive components. |
| Edge Quality | Heavy burrs, requires manual filing. | Vibratory tumbled for perfectly smooth, safe handling. |
From beryllium copper contacts to stainless steel micro-clips, we stamp a massive variety of specialty materials.

The True Cost of Cheap Tooling
Paying $500 less for a stamping die seems like a good deal until your assembly line stops because the parts have massive burrs. Tooling is an investment in quality.
At MSTFAB, we guarantee our progressive dies for the lifetime of your project. If the die wears out, we rebuild it at zero cost to you. You only pay for perfect parts.
Stop accepting defective parts. We deliver 100% inspected, ready-to-assemble components.
