Why Punching!

Pur Partner punches in almost all soft materials, such as solid rubber, cellular rubber, cellular plastics, polyurethane foam (PUR), blanket, cork, and more.

Punching in Soft Materials.

We primarily use knife punches to punch in different types of soft materials such as polyurethane, cardboard, rubber, plastic, packing materials and also textiles, etc. We can also help you with tool development as we have extensive experience of it.

Tool costs are also an important factor. Because the tools are simple, the tools can be cost-effective compared to the costs for water cutting, as the cost is very high.

A versatile process – which is cost-effective

For those who do not know what it means to punch, it can be likened to baking gingerbread. The dough can be anything from leather to plastic and the gingerbread shape is determined by you. This means that punching has a wide range of uses, but is mainly applied to produce seals, sound, and heat insulation.

Developing punching tools is a relatively low cost, which is why punching is suitable for both small and large series. Products that today are produced through advanced cutting could be manufactured both easier and faster by punching.

Punching is excellent for making gaskets. Of the inquiries we receive, it is about punching gaskets that is the most common and it is easy to understand. Very many different materials can be punched, below is a selection.

Examples of materials that can be punched

Punching.

Punching is a method used when making holes in relatively thin material. Thin means that the material is about 0.1 millimeters to 8 millimeters thick. Punching is carried out in various materials, such as sheet metal, plastic, paper, cardboard, natural rubber, silicone, and leather.

The method is that the punch, which is a tool, with the desired shape of the hole is pushed through the material under abutment pressure from a pad. This is an effective method in sheet metal processing. By optimizing with several tools, you can get more process steps in the same operation. Both the punch and the pad have sharpened edges with the same contour as the object to be punched. Rectangular punches and pads are used for contour punching.

Gaskets.

Gaskets are used in several different types of products. Today, we find our main customer base in the electronics industry. We can deliver basically anything when it comes to gaskets, for example, we have produced gaskets for forest machines, toilets, water pipes, and compressors for air and oil.

Environment and recycling.

We at PurPartner reuse all our waste from the punching, and all customers can send back used products to us, we mix 50% old material with 50% new and cast new products sold in our sister company Rosén Innovation AB.

We think this is to think environmentally friendly…
