The company is located just 5 minutes from the M4 corridor on the Treforest Industrial Estate, South Wales and employs approximately 90 people including a well-trained team of operatives as well as time-served toolmakers, tool designers and professionals.

Current Status

As with most SMEs, every effort is made to make the best use of the skills its employees already have together with the development and up-skilling of existing staff via a variety of training strategies.

Q4 2013 saw the company relocate to new, larger (35,000 sq ft) premises just a few miles from our original site.

2015 saw this building extended to 52,000 sq ft allowing for further growth.

2015 also saw the addition of 9 new Battenfeld moulding machines ranging from 60T to 300T.

2016 saw further investment in large capacity CNC milling with 5 axis machining capability plus 5 axis Wire EDM.

A new storage racking system was added in 2017 together with man-up FLT.

A company-wide training initiative was also launched in 2017, using a recognised training partner to deliver NVQ and BIT programs.

The Future

Additions in 2018 will include two new moulding machines, a 350T and a 1000T from Battenfeld, which will further increase our capacity and capability.
