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 Plastics 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.
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.
Laser and punching
Precision underpins everything we do at COBA Plastics. 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.
