Granulator Blade Changes
Our granulator blade change service ensures optimal performance of plastic recycling equipment. Using precision engineering techniques, we replace worn blades in industrial granulators across Bolton and nationwide. Our technicians follow strict safety protocols while maintaining blade alignment and chamber cleanliness to maximise equipment efficiency and extend component lifespan.
Injection Moulding Support
Specialist technical support for injection moulding operations covering machines from 15 to 3000 tonne capacity. Our engineers provide tooling design advice, process optimisation, and facility layout recommendations. We assist with material feed systems, robotics integration, and production efficiency improvements for plastic component manufacturers.
On-Site Hard Face Welding
Professional hard face welding services performed at client locations to repair and reinforce industrial equipment. Our certified welders use advanced techniques to restore worn components, extending machinery lifespan while maintaining structural integrity and operational safety standards in manufacturing environments.
Thermal Image Surveys
Preventative maintenance service using thermal imaging technology to detect equipment faults. Our engineers identify overheating components, electrical issues, and mechanical stress points in industrial machinery. This non-invasive diagnostic method helps prevent unexpected breakdowns and optimises maintenance scheduling for production facilities.
Machine Tool Maintenance
Comprehensive maintenance programs for industrial machinery including cyclones, ducting systems, and material handling equipment. We offer scheduled servicing, emergency repairs, and condition monitoring to ensure continuous operation. Our services cover cleaning, lubrication, calibration, and component replacement across multiple manufacturing sectors.
