Our continued investment in the latest technologies and our infrastructure as a whole, supported by the expertise of our people, gives us exceptional capabilities and scope to precisely meet our customers’ varied demands.

COBA Automotive has the capability to design and manufacture 100% of all tooling required for our manufacturing processes. We have in-house design, engineering and manufacturing capability as well as resources for testing and analysis. We have both injection moulding and over moulding equipment for both standard and complex components and finished assemblies.


Our material options are vast. There is a choice of over 30 different polymer types and grades processed from co-polymer polypropylenes to PE, PVC, SEBS, TPE, TPV and ABS. Over our 50 year history we have developed many top secret material mixes, designed to maximise durability, flexibility and resistance.


Our extrusion processes range from single material polymer extrusion, to multiple material ‘triple’ extrusion with wire inclusion, flock tapes, slip coating and surface preparation. COBA Automotive has some highly technical production lines and through expansion throughout the group, we continue to increase our capacity.

We also offer a wide range of ‘value adding’ downstream processes. These include punching, marking, coding and taping. Material options are vast. In excess of 30 different polymer types and grades are processed from co-polymer polypropylenes, PE, PVC, SEBS, TPE, TPV, ABS.

Downstream technologies

Precision underpins everything we do at COBA Automotive. As such we have the ability to laser profiles and non-wovens as part of the in-line extrusion process, as well as having off-line profile laser systems.

We use high power CO2 lasers with 2 and 3 axis galvo scanning heads, with power ranges from 100W to >600W. This technology gives us exceptional precision and fast cutting processes without the need for physical cutting tools.

Injection moulding

COBA Plastics Moulding have versatile moulding capabilities and this is proving invaluable in the development of technical components for our automotive customers.

Over moulding process combines extruded profiles and moulding to form a finished part. It’s a two-step process. The over moulding process uses a pre-formed extruded plastic part placed into an over moulding tool. The second material is then injected into the tool mechanically bonding to the extrusion to form a single piece component. Over moulding is a good choice for complex part shapes and for reducing the number of components required in assembly. Our machines range up to a maximum 420T and the service is supported by our experienced tool design and project management team. Two colour moulding and ultrasonic welding are also available from our site in Leicester. We offer guaranteed tooling life on all tools placed with us.


COBA is all about supporting the customer journey. That is why we offer a wide range of ‘value-adding’ downstream processes such as punching, marking, coding and taping. Our 2nd Operations team are skilled in complex assembly, providing our customers with a fully finished part ready for the production line.
