From the smithy to finished plastics part by injection moulding

15/6 2026

It started with a blacksmith, an idea to create a better hunter's chair, and a prototype made of iron and aluminium. Oskar from huntOS was looking for a plastics manufacturer who could help him bring his vision to life with injection moulding.

A hunter with an idea and a wish for plastic production

Like many other hunters, Oskar had found that hunting chairs can be uncomfortable to sit on for longer periods. So he came up with an idea. He wanted to create a combined hunting and shooting chair suitable for both shotgun and rifle hunting.

The hunting chair had to be light and easy to carry, almost silent to set up and provide a stable platform. As a trained blacksmith, he made a prototype out of iron and aluminium, which he adjusted several times. But he knew from the start that the final chair needed to be made of plastic and injection moulded.

The right partner for plastics production

Oskar was looking for a plastics manufacturer who could help and advise him on plastics and injection moulding. That is how he came into contact with Idé-Pro.

‘'Idé-Pro were very helpful and receptive to my idea. They wanted to help me take the project forward and offered to draw and design the chair so that it would fit their tools.''

That marked the start of a collaboration and a process that helped Oskar realise his idea.

Design optimisation using 3D-printed prototypes

To adjust and optimise the design of the hunting chair as effectively and cost-effectively as possible, we suggested 3D printing a prototype.

''Idé-Pro advised me to have a 3D print of the chair made before production. It was definitely a good decision.''

There was room for improvement in the first 3D-printed prototype. In collaboration, we optimised the design and, to be extra thorough in the prototyping process, we had another prototype 3D-printed with the new design changes.

This time, the result was exactly as Oskar had wanted, and with the optimised design, we began tooling production.

From tool manufacturing to injection moulding in three plastic materials

The hunting chair consists of six injection moulded parts, each of which is moulded in the plastic material best suited to its function. Four of the parts are moulded in PP, whilst one is in PA6 and one in POM. The parts are injection moulded using six different tools, which we have manufactured in our in-house tool factory.

Two of the parts are moulded using a foaming agent, a moulding technique that foams the material during injection moulding, thereby reducing the weight of the part. This technique also allows for a high wall thickness, making the parts more rigid and stable.

The support bracket on the hunting chair is moulded using this technique, where stability plays a particularly important role when a shotgun or rifle is resting on it.

Danish production for trust, fast delivery and transparency

For Oskar, choosing a Danish partner for his project was a no-brainer. As a new entrepreneur, he needed to be close to the production process. It was also important that it was a Danish company he could trust, one that offered fast and effective communication regarding adjustments and the development of the parts.

Fast delivery and transparency regarding production, including consideration for the environment, were also decisive factors in his choice.

‘I am grateful that Idé-Pro believed in me and my idea, and that they were willing to help a new entrepreneur get started with advice and guidance.’
