Stamping is one of the most efficient manufacturing techniques for producing large numbers of identical parts with consistent dimensional accuracy. At high production volumes, stamping provides a structurally lower unit cost compared to alternative cutting or forming techniques. Tooling costs are spread over large series, allowing the investment in a stamping die to be quickly recouped. Repeatability and cycle time are the two factors that make stamping suitable for mass production.

Stansen is een productieproces waarbij materiaal, meestal metaal of kunststof, uit een grotere plaat of rol wordt gesneden met behulp van een stansmes of -matrijs. Dit proces wordt vaak gebruikt voor het maken van complexe vormen, contouren en gaten in een materiaal. **Wanneer is stansen geschikt voor hoge volumes?** Stansen is uitermate geschikt voor hoge volume producties vanwege de volgende redenen: * **Snelheid en Efficiëntie:** Eenmaal de stansvorm is geproduceerd, kunnen stansmachines grote aantallen onderdelen per minuut verwerken. Dit maakt het proces zeer snel en efficiënt voor massaproductie. * **Kosteneffectiviteit bij grote volumes:** Hoewel de initiële kosten voor het maken van de stansvorm aanzienlijk kunnen zijn, worden deze kosten snel terugverdiend bij het produceren van grote hoeveelheden. Per individueel onderdeel worden de productiekosten laag. * **Consistentie en Precisie:** Stansen levert zeer consistente en precieze resultaten. Elke gesneden onderdeel zal identiek zijn aan de vorige en volgende, wat cruciaal is voor kwaliteitscontrole in massaproductie. * **Automatisering:** Stansprocessen kunnen gemakkelijk worden geautomatiseerd, wat leidt tot nog hogere productiesnelheden en lagere arbeidskosten, ideaal voor hoogvolume scenario's. * **Materiaalspecificaties:** Stansen kan op een breed scala aan materialen worden toegepast, waaronder dunne metalen platen, kunststoffen, papier en karton, wat het geschikt maakt voor diverse industrieën die in grote volumes produceren. Kortom, stansen is een economische en efficiënte methode voor het produceren van grote aantallen identieke onderdelen wanneer de initiële investering in stansgereedschappen gerechtvaardigd is door het volume.

Stamping is a machining technique where a stamping tool cuts out, forms, or perforates material with high precision and speed in one or more strokes.

The technique is applied to sheet material, film, rubber, plastic and composite. The suitability for high production volumes is related to the nature of the process: once a die-cutting machine is set up, each stroke repeats with a virtually identical result. Cycle times, depending on the type of machine and the complexity of the product, range between 20 and 400 strokes per minute.

Stamping is technically suitable for high volumes when:

• The product has a fixed geometry with no frequent changes
• The material to be processed is suitable for flat delivery (web, roll or sheet)
• Tolerances are in the range of ±0.05 mm to ±0.2 mm, depending on material and tooling quality
• The series is large enough to justify the tool investment, typically from 10,000 pieces, but this varies by application

For smaller series or more complex three-dimensional shapes, alternative techniques such as Laser cutting Waterjet cutting is more economically attractive.

Why is stamping more cost-efficient at increasing volumes?

The cost per unit structurally decreases as production volume increases, because fixed tooling costs are spread over more units.

This is the fundamental economic principle behind die-cutting. The die set, consisting of a punch, a die and a guide, represents a one-off investment. This investment typically ranges from a few thousand euros for simple tools to tens of thousands of euros for complex progressive dies. Once produced, the die can produce millions of strokes without a significant increase in unit costs.

By way of comparison:

• Laser cutting has low set-up costs but a longer cycle time per item; for large volumes, this becomes costly
• Waterjet cutting is flexible but has a low production speed, which keeps the unit cost high when producing large volumes
• Stamping has high initial tooling costs but the lowest unit price at volumes above the break-even point.

At Euro-Techniek, we calculate the break-even volume for every project, so the choice for stansen is based on facts and not on assumption.

The six technical advantages of die cutting in mass production

For high production volumes, die-cutting offers a combination of speed, repeatability and material control that other cutting and forming techniques cannot match.

The six advantages that are most significant in a mass production context:

Long cycle time

Progressive die-cutting machines achieve production speeds of 100 to 400 strokes per minute. For simple geometries, this translates to an output of thousands of products per hour.

Consistent dimensional accuracy

Every stroke of the tool produces an identical result. There is no cumulative deviation as with manual or semi-automatic operations. Tolerances are reproducible over the entire production volume.

Minimal material loss

By optimising tool design for nesting efficiency – the arrangement of products on the strip or sheet – material wastage is minimised. With well-designed tools, material yield exceeds 85%.

Integration of multiple operations

With progressive stamping, multiple operations are performed in a single pass: cutting, bending, perforating, and deep drawing. This eliminates intermediate handling and reduces the overall lead time.

Low work intensity

After setup and verification, the production process is largely automated. The operator monitors the process but does not perform an action per product. This significantly lowers the labour costs per unit.

Long tool life

A high-quality die made from tool steel (such as 1.2379 or 1.2842) has a service life of between 500,000 and over 5 million strokes, depending on material thickness and stroke frequency. Over that service life, the tooling costs per unit are negligible.

Welke materialen zijn geschikt voor stansen in grote volumes?

Not every material is equally suitable for die-cutting, and the choice of material directly affects tool life, cycle time, and the quality of the cut edge.

Materials that are routinely processed well in high volumes:

• Cold rolled steel (DC01, DC04): Most commonly used in practice. Good punchability, low tool wear, suitable for deep drawing
• Stainless steel (304, 316): Requires higher cutting forces and causes greater tool wear, but is highly versatile for hygiene and outdoor applications
• Aluminium (1050, 5052, 6061): Low weight, good formability, limited springback when bent
• Copper and copper alloys (brass, bronze): Electrically conductive, often used in connectors and contacts; requires sharp tools
• Plastic film and rubber Cut with die-cutting (rule dies) of cemented carbide tools; applications in sealing, packaging, and insulation

Materials that are less suitable for stamping include hard alloys with limited ductility, such as titanium or hardened steel. These materials experience high cutting forces that rapidly wear or damage tools.

Enkelvoudig stansen, ook bekend als enkelvoudig trekken, is een proces waarbij één enkele persslag wordt gebruikt om een vorm in een metaalplaat te produceren. In tegenstelling hiermee is progressief stansen een techniek waarbij meerdere bewerkingen, zoals ponsen, buigen en snijden, na elkaar worden uitgevoerd in dezelfde reeks matrijzen achter elkaar tijdens een continue beweging van de pers.

Single stamping performs one operation on one position per stroke; progressive stamping performs multiple operations on successive positions along a continuous strip per stroke.

The difference is decisive when choosing for high production volumes.

For single stamping:

• One tool, one operation per stroke
• Suitable for simple geometries or large products that do not fit in a belt.
• Lower tooling costs, but longer cycle time per finished product
• Interim action or transfer required with multiple processing steps

When progressive stamping:

• Multiple stations in one tool; the product is formed step by step
• Significantly higher output per time unit
• Higher tooling costs due to complexity, but lower unit price at volume
• Requires a continuous power supply and precise positioning between stations
• Suitable for products with complex geometries: combinations of cutting, bend, piercing and deep drawing in a single tool pass

At Euro-Techniek, we determine the most technically and economically viable punching method per product and per volume. The choice is substantiated with tool and cost calculations.

Quality assurance for die-cut series

Quality assurance in stamping focuses on monitoring dimensional consistency, cut edge quality, and tool condition across the entire production batch.

With high production volumes, small deviations that occur early on are decisive for the quality of the entire batch. The inspection approach consists of:

• First Article Inspection (FAI): The first products of a new series are fully measured and approved before production release.
• Statistical Process Control (SPC) At critical measurements, intermediate samples are taken and recorded to signal trending deviations.
• Tool inspection: Following a set number of strokes, the tool is inspected for wear on stamp en Die cutting edge
• Cut edge analysis The relationship between Shaving zone en fault zone On the cutting edge, this provides insight into the tool's condition; an increasing fracture zone indicates tool wear.
• Dimensional registration Measurement results are recorded and traceable per production order

At Euro-Techniek, measurement results are documented as standard and are supplied as part of the production documentation.
