Capability at a glance
| Strip thickness | 0.2 – 4 mm steel, stainless steel, aluminium, copper, brass, phosphor bronze |
|---|---|
| Press range | 25 – 200 ton mechanical presses with progressive, compound and transfer dies |
| Stamping tolerance | ±0.05 mm on cut and formed features, ±0.02 mm on superfine blanking where required |
| Burr height | Controlled by die clearance and maintenance; typically below 0.05 mm, tighter on request |
| Maximum blank size | Up to 600 x 600 mm depending on press and die size |
| Tooling | Designed and manufactured in house; progressive, compound, transfer and blanking dies |
| Volume | 10,000 – 1,000,000+ pieces per year is the economic range for dedicated dies |
| Lead time | Die making 15-25 working days after design approval, then samples before serial production |
Materials we work with
| Material | Typical range and notes |
|---|---|
| Cold rolled steel | SPCC, DC01, 1008/1010 – general purpose, easy to form and plate |
| Galvanised and pre-coated | SECC, SGCC – corrosion resistant, used for enclosures and mounting parts |
| Stainless steel | 301 spring temper, 304, 430 – for spring contacts, clips and corrosive environments |
| Aluminium | 1050, 1060, 5052, 6061 – light weight stamped parts, good for housings and shields |
| Copper and copper alloys | C11000, C2680, C5210 phosphor bronze, beryllium copper – for conductive and spring parts |
| Electrical steel | Silicon steel M19 / 50W470 – for laminations and magnetic cores |
How the process runs
1. Part and die review
We review your drawing and annual volume to select between progressive, compound and transfer dies, then confirm strip width, die clearance, pilot holes and strip layout.
2. Die design and approval
Die drawings are issued for your approval before steel is cut. Strip layout, material utilisation and station sequence are shown so that the unit price is transparent from the start.
3. Die manufacturing
Die plates, punches and inserts are machined, ground and heat treated in house, then assembled and tested on the press that will run production.
4. Sampling and first article
Short-run samples are produced for your dimensional and functional approval. Adjustments are made to the die at this stage, not during serial production.
5. Serial stamping
Production runs with in-process inspection at fixed intervals. Die maintenance is scheduled from the running count so that burr height and dimensions stay inside tolerance.
6. Secondary operations
Deburring, tapping, heat treatment, plating, welding, insert fitting and assembly are added according to your drawing.
Design for manufacture: what to check before you send the drawing
- Design with a uniform wall thickness. A single strip gauge removes an extra forming station and reduces the die cost.
- Keep the minimum hole diameter and the minimum slot width at least equal to the strip thickness, otherwise punches break early.
- Keep stamped features at least 1.5 x thickness away from the outside edge to avoid distortion of the blank.
- Allow a bend radius of at least 0.5 x thickness for steel, and account for springback on stainless and spring alloys.
- Specify which side the burr may appear on. Burr direction usually cannot be reversed without adding a station.
- Provide a drawing with datum planes and tolerances on the features that matter. A fully toleranced drawing is not needed and only raises the inspection cost.
- Send the estimated annual volume and the expected product life. Tooling amortisation is the main cost driver, so the volume decides the right die type.
Quality control
The factory operates a quality management system certified to ISO 9001 and IATF 16949. Inspection records, material certificates and coating reports travel with the shipment.
| Stage | What is checked |
|---|---|
| Material | Mill certificates for every strip lot, with chemical composition and mechanical properties |
| Die validation | Capability study at sampling stage, including Cp / Cpk on critical dimensions where required |
| In-process | Fixed-interval inspection during production, recorded against the part number |
| Final inspection | Projector, optical and CMM measurement, plus functional inspection of spring or contact force |
| Plating | Plating thickness and solderability tests, salt spray testing for corrosion resistance |
| Traceability | Batch and lot traceability from strip material through stamping, plating and packing |
FAQ
When does stamping become cheaper than other processes?
Dedicated dies make sense from roughly 10,000 pieces per year. Below that, laser cutting, CNC punching or CNC machining usually gives a lower total cost because there is no tooling to amortise. We will tell you honestly which route is cheaper for your volume.
Who owns the tooling?
The tooling is paid for by you and is used only for your parts. Ownership and maintenance responsibility are written into the quotation so that there is no ambiguity later.
Can you run parts from our existing dies?
Yes, if the die is in good condition and fits one of our presses. We will ask for die drawings or a physical inspection before committing to the production window.
How do you control burr height on stamped parts?
Burr height is controlled by die clearance, punch sharpness and maintenance interval. The acceptable burr limit is agreed at sampling stage and monitored during production; deburring and tumbling are available when a very small burr is required.
Which materials can you stamp?
Mild steel, galvanised steel, stainless steel 301/304/430, aluminium, copper, brass, phosphor bronze, beryllium copper and silicon steel.
Do you handle heat treatment and plating?
Yes. Stress relief, hardening and tempering, zinc and nickel plating, silver plating, tin plating and passivation are all arranged according to your drawing.
