Punching moulds
We design and manufacture die sets — flat dies made from tool steel — for die-cutting rubber, plastic, insulation, tape and other soft materials. With over 60 years’ experience and all manufacturing carried out in-house in Bromma, we take responsibility for the entire process: from drawing and CAD design to test runs and measurement reports.

Die vs die set
The terms overlap, but there is a practical difference:
Die (flat die): A die is a moulding tool. It is usually manufactured with a steel line in a plywood sheet (steel line die) or with a welded steel line on a sheet metal plate or welded frame (die cutter), often with multiple cavities, designed for flat pressing. The die presses the material through against a cushion, creating contours, holes and shapes with high precision and repeatability. Flat punches are suitable for higher requirements in terms of tolerance, surface finish and process capability (Cp/Cpk).
Punching tools (collective term): ”Punching tools” is a broader term that encompasses all types of tools used for punching: steel strip tools (the most common and cost-effective type), welded punching dies and rotary punching tools.
Rule of thumb: Do you need a cost-effective tool for series production in soft materials? Start with a steel line tools. Do you have high requirements in terms of tolerance, surface finish or process capability? Choose a die-cut mould or flat die-cut.
Design, manufacturing and testing in Bromma
We develop and manufacture die-cutting tools at our own premises in Bromma. With over 60 years’ experience, we take responsibility for the entire process, from CAD design and material selection to trial runs and measurement reports. The result is reliable production, tight tolerances and short lead times.
Do you need a new die or want to optimise an existing one?
Please send us the drawings, materials and quantities, and we will get back to you with a proposal, lead time and quotation.
Why choose Stans-Service
- Everything in-house in Bromma – faster decision-making and shorter lead times.
- Repeatability in series – trial runs under production-like conditions and documented measurement data, such as Cp/Cpk.
- Optimised tool geometry - Angles of cut, restraints and steel selection are customised according to materials and tolerances.
- Service life and maintenance - trimming, maintenance and monitoring for consistent quality over time.
- Industrial die-cutting moulds, not hobby products – We manufacture moulds from tool steel for the industrial mass production of rubber, plastic and insulation components. We build precision tools for the manufacturing industry.
What we deliver
- Die-cutting moulds and flat punches for soft materials and foils.
- Prototypes and pilot series for quick verification and DFM feedback.
- Test drive and measurement report - we drive, measure and adjust before handover.
- Spare parts and maintenance for high availability in your production.
Materials and formats we process
- Plastic film (PET, PI, PC) and soft plastics (PE, PP, PVC, PTFE, etc.)
- Foam, rubber and cellular rubber
- Paper and cardboard
- Self-adhesive materials, including kiss-cut versions of thermal pads and tape details
- Insulation materials such as Nomex, Kapton and mica
Dimensions and tolerances
- Detail size: from approximately 3 × 3 mm up to approximately 650 × 1600 mm, depending on the material, format and machine.
- Thicknesses: plastic films, typically 0.05–0.5 mm thick, and soft plastics up to approximately 3 mm thick.
- Tolerances: is determined by the requirements and materials. We ensure that cut quality, burr formation and repeatability meet your Cp/Cpk targets.
Please note that spans and tolerances are affected by material, geometry and volume. We always verify in a test run.
Typical applications
Gaskets, spacers, insulation and protective components for the electronics and other industrial sectors, including thermal pads and self-adhesive components.
This is how we work
- Background and requirements - drawing, material, annual volume, tolerances and function.
- CAD design - choice of steel, cutting edge geometry, clearances and restraints.
- In-house manufacturing - short decision-making paths and high traceability.
- Test drive - production-like conditions, adjustments and trims.
- Measurement and documentation – measurement reports and Cp/Cpk as required.
- Handover and follow-up - support, spare parts and service plan.
