About Us


G-Pack Manufacturing  Limited established in Glossop, Derbyshire in 1999.  We are centrally located within the U.K. between Manchester and Sheffield.

We are a specialist injection moulding company, independent in ownership and control.  G-Pack are company members of the Glass and Glazing Federation and registered to IOS 9001 2015.

Manufacturing is carried out to ISO 9001 quality standards, moulding  machine capabilities range from 70 tonnes up to 200 tonnes. We have invested heavily in mould tool design and manufacture, almost all tools have full hot runner systems, this reduces cycle time, eliminates waste and recycling when moulding, resulting in a very lean and cost efficient manufacturing process.

We manufacture solely for the U.K. glazing industry, particularly trade uPVC window fabricators, profile extrusion companies, trade counters and larger installation companies.  We pride ourselves on researching and developing bespoke precision parts.

All new components will first be 3D printed to check the fit and tolerances,  prior to prototype or full production tooling.  We have design registration on a number of parts that we have developed in-house,  always  taking on board customer feedback on functionality and cost.
