Abstract
A method for producing a connecting part (28) uses an injection foam molding process. In a first step, a fastening part with adhesive and/or hooking elements (18), forming a component of a contact fastener, is produced and introduced into an injection mold (2) as an insert part (16). A support part (26) is formed in the mold in a second step using a foamed synthetic material (22). The support part is connected to the insert part to form the connecting part (28).
Claims11
A method for producing a connecting part, comprising the steps of:
- providing a fastening part forming a component of a contact fastener and having at least one of adhesive elements or hooking elements;
- introducing the fastening part as an insert part into an injection mold having air channels such that the at least one of adhesive elements or hooking elements face and are exposed to the air channels;
- and
- producing the connecting part by injection foam molding in the interior of the injection mold in which a support part is formed by a foamed synthetic material and is connected to the insert part on a side of the insert part remote from the at least one of adhesive elements or hooking elements to form the connecting part, while at least one of suction air or a pressurized supporting gas is supplied via the air channels.
