Tie Down

Tie Down solutions for automotive seat cover applications have been an area of significant growth for COBA Plastics over recent years. COBA Tie Down delivers a number of proven cost reduction and finished product benefits to our seating customers.

A dual material component, it features an extruded bead bonded onto a flange of fleece. Tie Down locks down the material cover into the foam used in the seating mechanism, creating smart definition lines for stylish seats.

We offer a range of value adding down line processes. COBA Tie Down can be hog ringed or an injection moulded clip can be formed into the foam.

COBAflex solutions can feature any trim retainer bonded onto a non-woven fleece. Used for front seat applications, it is attaches the trim cover to the underside of the seat pan. COBAflex helps to reduce the amount of premium car seat material that is required and removes a sewing operation for our customers. This naturally enables us to bring cost reduction benefits to our customers.

It can be lasered, punched (either pneumatic or hydraulic) or injection moulded.
