Metal Stamping
High-volume precision parts, made fast and consistent.
Precision stamping turns sheet metal into repeatable, dimensionally accurate components at production speeds that machining cannot match economically.
Overview
Metal stamping is a cold-forming process in which a press and dies are used to form sheet metal or coil stock into precision parts at high efficiency. It covers blanking, piercing, bending, deep drawing and progressive-die production. Once the tooling is invested in, unit cost is low, production speed is high and batch consistency is excellent - making it the preferred process for high-volume production of hardware brackets, clips, panels, enclosures and similar products.
How the Process Works
Part development (flat-pattern calculation), stamping process layout and die development
Align and mount the upper and lower dies; run a first-article trial and confirm acceptance before volume production
Uncoil, level and feed coil stock, or load and position sheet blanks
High-speed stamping with continuous blanking / forming stations
Separate finished parts, clear scrap and maintain continuous production;
Sampling inspection of dimensions and appearance; accepted parts proceed to bending, welding or surface finishing.
Key Advantages
- High-speed continuous production - one part per press stroke, and multi-station progressive dies run without stopping, giving extremely high efficiency at volume
- Highly automated - coil feeding plus progressive dies can be linked into an automatic line with minimal manual labour
- Low unit cost at high volume - once tooling cost is amortized, unit cost is far lower than laser cutting or machining
- High material utilization - optimized nesting layouts keep scrap manageable and recyclable
- Precise dimensions, consistent batches - guaranteed by the die, so parts from the same tool are highly uniform
- Stable batch quality - minimal variation even at high production speed, ideal for volume deliveries
- Work hardening increases strength - cold stamping raises material strength after forming (for certain forming operations)
- Good surface quality - the polished die forming surface means most parts need no secondary machining

Frequently Asked Questions
Q: How is tooling cost calculated?
A: Tooling is quoted separately and is normally borne by the customer (or amortized over the order quantity in stages); the exact figure is subject to quotation.
Q: Who owns the tooling?
A: If the customer pays for the tooling, the tooling belongs to the customer, and repeat orders only incur production cost.
Q: What materials can you use?
A: Carbon steel, stainless steel, aluminium, copper and other metal sheet - the material is selected according to the drawing.
Q: How thick a sheet can you stamp?
A: It depends on press tonnage - higher tonnage handles thicker material; the specific capability depends on the machine.
Q: How are samples produced?
A: Samples can be laser-cut without opening a die, giving short lead times and low cost.
