ABSTRACT:
A milking device includes at least a teat-receiving flexible sleeve, adapted to be positioned on/over a teat. A first portion thereof includes a material, selected from the group consisting of thermo-plastic elastomers (TPE), as defined in ISO 18064, and a second portion thereof includes a material selected from the group consisting of thermoplastics. The method of making a milking device, in particular a teat cup liner, is a molding process carried out in two or more steps. In the first step, a thermoplastic, preferably polypropylene (PP) or polyamide (PA), is injected in a mold defining only those portions of the device that are to exhibit a higher stiffness or rigidity, such as couplings. The stiffer parts, are demolded from the mold, and placed in a second mold, into which, as a second molding step, a suitable TPE is injected. Further steps can be performed if required by the design.
