A material of excellence
TPU are thermoplastics elastomeric which combine elastic properties of elastomeric and mechanical properties of plastics. This material is very resistant to abrasion, it can be combined with other materials, and it is recyclable.
We are known for our experience and our expertise of the product. We are transforming more than 100 tons of this material each year. Auray Plast designs and produces technical plastic parts meeting to very strict specifications regarding the respect of dimensions and geometry.
Process
At Auray Plast, we transform TPU by injection. It means that we melt pellets which are die-cast in steel moulds. It can ensure us to make practically any parts in our factory. We have 25 injection moulding machines from 30 tons to 350 tons. All of them are recent, and a majority are electric for more precision and cleanliness.
We are answering with our engineer office to all your demands requiring specialists of these materials.
