SG Moulding Solutions is the exclusive UK agent for SST Microwelding, delivering specialist high-precision microwelding and mould repair services to the UK plastics, packaging and tooling industries.
SST Microwelding is internationally recognised for repairing, modifying and extending the life of high-value mould tools where dimensional accuracy, cosmetic finish and metallurgical integrity are critical.
By working through SG Moulding Solutions, all UK representation, commercial coordination, logistics and post-Brexit import requirements are handled locally. You deal with a UK company, a named UK contact and UK-based support, while accessing specialist European capability without added complexity or risk.
Microwelding is a highly controlled repair process designed for intricate tooling features where conventional welding or machining is not suitable. Using extremely low heat input, material can be added with exceptional precision while minimising distortion, cracking or damage to surrounding areas.
This makes microwelding particularly effective for high-value injection moulding, blow moulding and packaging tools where downtime, scrap and tool replacement costs must be tightly controlled.
Unlike traditional laser welding systems, SST Microwelding is fully portable. This is a major advantage when working with large tonnage tooling.
In many cases, repairs can be carried out directly in the press, avoiding the need to remove very heavy moulds. This significantly reduces downtime, eliminates unnecessary handling and allows production to resume faster.
For moulders operating high hourly rate machines, this delivers measurable commercial benefits:
For high-output moulding operations, portability and downtime reduction are often more critical than theoretical weld speed alone — making microwelding a highly practical solution.
SST Microwelding services are commonly used for:
This is particularly valuable for high-cavity, cosmetic and tight-tolerance packaging moulds.
SST Microwelding processes are suitable for a wide range of tooling materials, including:
This allows both steel and aluminium tooling to be repaired or modified without compromising structural integrity, accuracy or surface finish.
As exclusive UK agent, SG Moulding Solutions provides more than representation.
Simon Girdlestone, founder of SG Moulding Solutions, is trained as a mould toolmaker, bringing real, hands-on tooling experience to every discussion. This ensures repairs are assessed with a practical understanding of tool function, manufacturability and long-term performance.
Yes. Many repairs can be completed in situ thanks to the portable microwelding process, particularly on large tonnage tooling.
No. SG Moulding Solutions manages all commercial coordination and post-Brexit import requirements.
Yes. Aluminium moulds, inserts and other non-ferrous materials are fully supported.
The extremely low heat input significantly reduces distortion risk compared to conventional welding methods.
Absolutely. It is commonly used where downtime and output loss are commercially critical.
If you have a tooling issue on a high-value or high-output mould, speak to someone who understands tooling and production realities.
