Glossbrook Engineering Ltd (Scotland)


Our 20 plastic injection moulding machines range from 25 tonne to 500 tonne. Six of our machines have digital PLC control and 14 are microprocessor controlled. We have recently purchased closed loop feeder systems for our high volume production run machines. During 2013, we installed a new Krauss Maffei 500 tonne moulding machine, the largest of it's kind in Scotland.

With years of experience in this industry, we are expert plastic moulders and toolmakers.

Injection Mould Tooling

We are highly experienced and knowledgable precision mould tool manufacturers. Modern techniques are used in the design process to create CAD-based injection mould tool designs. Our expert engineers operate within a fully equipped tool-room where modern equipment such as CNC machinery, spark erosion machines, etc are employed in our mould-tool manufacturing processes.

Plastic Moulder and Mould Tool-Maker

We are a plastic mould toolmaker and injection moulder with many years of experience.

We have unrivalled knowledge in mould tool design and manufacture, materials processing and injection moulding. We can produce technical moulded components in a virtually all thermoplastics from commodity materials such as polypropylene and HIPS through to engineering materials such as glass filled polyamide, polycarbonate and polyphenylene sulfide (PPS).

Form In Place Gasketing

We provide post operation, form in place gasketing.

Our form in place gasketing is a precision CNC-controlled process. After programming the relevant pathways, our CNC machines dispense specialist silicones to form gaskets, o-rings, seals, etc to customer specifications. Once programmed, the process is always repeated to the same specification, resulting in precision gasketing to shapes of any complexity.

Vacuum Plating

We have continually developed our vacuum plating process over many years. We can provide a chrome-like finish to many materials and currently service a number of end-user applications.

Spray Painting

We offer spray painting as a post-moulding operation. We adopted this secondary process a number of years ago and now provide many customers with components which are spray-painted for a variety of reasons, ranging from purely aesthetic to function-specific, such as electro-shielding.

Ultrasonic Welding

In some instances, ultrasonic welding is the best solution where sealing plastic components comprised of two halves is necessary. We can create a strong, alignment-error free weld.

Ultrasonic welding is a technique where ultra-high frequency sound waves create a weld by vibrating component halves together. Specialist equipment and knowledge is employed in the process.

Hot Foil Blocking

Using our hot foil blocking process, wording, logos and patterns can be added to injection moulded components. The form can be fairly complex and produced in any colour with gloss or matt finishes.
