Technical Resource Centre
Part of SGH Technical Resource Centre – Home
At SGH, we have been designing, manufacturing and assembling injection moulded components in the UK for over 40 years. This resource centre reflects how we operate in practice; from Design for Manufacture through to PPAP, serial moulding, cleanroom assembly and long-term tool lifecycle management.
The SGH Technical Resource Centre has been developed to provide structured insight into how we approach injection moulding, tooling strategy, dimensional control and supply integration.
Rather than presenting isolated service summaries, this Centre explains the technical and operational systems that underpin stable manufacturing performance.
How to Use This Resource Centre
Each section reflects real production capability within our 25-press facility, supported by ISO-governed quality systems and structured lifecycle management.
- Design and feasibility
- Tooling strategy and validation
- Material behaviour and dimensional control
- Production and high-mix coordination
- Logistics, sustainability and digital transparency
The pages within this Centre are structured to follow the lifecycle of a typical injection moulding programme:

A Structured Manufacturing Partnership
The SGH Technical Resource Centre reflects our belief that manufacturing stability is engineered through systems, not promises.
By integrating:
- Design for Manufacture
- Controlled tool validation
- Preventative servicing
- High-mix planning
- Warehousing integration
- Environmental governance
- Digital transparency
we provide a structured and accountable manufacturing environment.
If you are planning a new moulding project or reviewing an existing supply arrangement, our technical team can assess feasibility, material suitability and production strategy from the outset.
