At the design meeting, we go through production conditions and requirements with the customer.


A mould flow analysis shows that a mould functions as expected as regards, amongst other things, flow, pressure and cooling.

Tooling adjustment

Because we have our own workshop, we can rapidly adjust tooling if the need arises.

In the injection moulder

A robot removes an injection moulded hard hat. To give the hat a shiny surface, the mould has a polished cavity.



Meticulous measuring throughout production ensures a high-precision finished product.



Assembly is, in itself, an extra check of the finished product. Certain parts are assembled before injection moulding. Others, e.g. electronics, are mounted on or in the finished component.


Injection moulded goods – from idea to finished product

Our expertise and experience are at your disposal from the very first idea until full production runs emerge from our facilities. To help our customers avoid technical and financial pitfalls in the production stage, we are happy to be involved in projects as early as possible.

Design and engineering

All products are made to serve a purpose. They must perform a certain function, be easy to use and, preferably, attractive. On top of this, it must be possible to make them profitably.

All the above factors must be borne in mind throughout design and engineering. We often finalise both of these in close collaboration with the customer’s own designers and engineers. We can give valuable advice on material selection and the impact on product design of technical considerations in the production phase.

If you yourself are unable to provide construction drawings, we can help with the production of detailed, 2D and 3D drawings.


To provide a better idea of the finished product, an SLA or SLS model can be made in the chosen material. This is done before any tooling is produced. A model can also facilitate the manufacture of parts that are to be connected to, or assembled with, the product. In appearance, the models are so like the finished product that they can even be used in marketing, a phase which might otherwise sometimes have to be delayed to just before production.

Tooling production

When the tooling drawings are ready, the dies/moulds are made in China. Working ten years with the same supplier has resulted in an efficient collaboration that, despite the distance, gives our customers economic advantages.

When the tooling arrives in Kungälv, we use our injection moulding machines to verify that it works as planned. If necessary, we carry out a mould flow analysis to check that: moulds fill correctly; plastic and tooling maintain the right temperature; and, pressure and cooling time are optimal.

Reference samples

The next step is to make reference samples. These are checked using advanced measuring equipment. A measurement report is printed and reviewed. If it proves necessary to adjust the tooling, this is done in our own workshop in Kungälv. Consequently, production can soon be started up.


Currently, our plastics department has 17 injection moulding machines offering clamping forces from 40 to 275 tonnes. Some of our machines can work unattended all day round.

Post-production processing

So that our customers do not have the bother of involving other subcontractors, we can take care of assembling and packaging the finished product. Where necessary, we can even carry out function testing of products before delivery.

Ultrasonic welding, electronics assembly, pad printing of texts/logos and foil laminating are examples of the post-production processes we offer.


The tooling department deals with enquiries and develops prototypes and finished tooling for injection moulding.

The workshop in Kungälv handles adjustment and repair of our tooling. This means we can rapidly modify or mend tooling without unnecessary production stops.
