Whether it’s producing components for breathing aids during the Covid pandemic or helping automotive OEMs reduce vehicle weight through precise engineering, COBA Plastics Group is never standing still. Featured in the London Stock Exchange’s ‘1000 Companies to Inspire Britain’ in 2020, and a staple of Leicestershire’s Top 200 Companies, COBA has come a long way in the last fifty five years.
COBA Plastics Group is a unique and privately funded set of international manufacturing businesses, invested primarily but not exclusively in the manufacture of thermoplastic products. We have strong values, a family-like cohesiveness, and attention to detail that sets us apart.
Following the strategic demerger of COBA International Ltd, COBA Plastics Group has rebranded its plastics manufacturing and engineering divisions. The newly restructured entities include:
COBA Plastics Group (formerly COBA Automotive, COBA Precision Engineering, and COBA Plastics Moulding), which has been extruding plastic for over fifty years and has become a go-to supplier for many brands in the car industry.
From car glazing seals to shower head components, COBA Plastics Group has been converting raw polymers into useful products for more than fifty years. Find out more about the different sectors in which we operate below.
