FIELD: machine engineering.
SUBSTANCE: each segment 18, 20 is formed from a first polymeric material and comprises at least one working surface 28 formed from the second polymer material undergoing a two-component injection moulding with the first polymeric material segment. The work surface may be a contact surface with a spatula. In this case, the working surface has a projection and is made of an elastomeric material. The working surface may also be an inner surface 28 adapted for engagement with abradable material. In this case, the silicone material can be used to provide adhesion abradable silicone base material. The working surface may also be a side surface of the front or rear of the chassis, wherein the surface is intended for contact with a corresponding fixed surface. In this case, the material may comprise Teflon in order to make the working surface of the frictional properties in the dry state.
EFFECT: invention allows the body to give additional technical features directly in the injection moulding of the housing segments.
