How We Work

Linear Plastics is focussed on delivering exceptional customer service via the excellence of its workforce and production systems.

Everyone at Linear Plastics — from top to bottom — is equipped with a training and development plan and given clarity around all job functions and expectations. These functions are many and varied, including on-site trained machine operatives, time-served toolmakers, tooling and product designers and other professionals.

Year-on-year productivity increases at Linear Plastis thanks to programmes of continuous improvement, automation and skillful capital investment. No aspect of the company’s tooling and plastics processing activities remains untouched in a drive to optimize manufacturing efficiency. Quality consistency and waste reduction efficiency have been two key outcomes, together with a consequent up-skilling of the human contribution.

Linear Plastics continuously invests in the company’s total quantum of all these skill levels.

The company’s business fields and moulding markets are very diverse, spanning a range of industries such as office furniture, construction, aerospace, medical, and electronics.

During 2019 we placed a considerable portion of our business with LP and the results have proven very successful. We were looking for a local manufacturing partner that offered scalability and professionalism, but still with a personal touch — we found just that.
