Precision Engineering
Our precision engineering division utilises CNC and manual machining capabilities to deliver components to exact specifications. We maintain tolerances using digital technology across milling, turning, and grinding operations. The workshop handles complex projects requiring modification, repair, or fabrication of engineering components.
Rotary Valve Manufacturing
We design and manufacture rotary valves in mild steel with chrome finishes or fully stainless steel configurations. Our valves feature precision-ground surfaces and axial rotor systems for improved throughput. Custom mobile units with hydraulic or electrical drive systems are available to specific requirements.
On-site Repairs
Our engineers provide comprehensive on-site repair services for machinery and valve systems. The mobile service team responds rapidly to breakdown situations, equipped to perform emergency repairs at client locations using portable welding and machining equipment.
Machinery Modification
We implement modifications to enhance machinery performance, safety, and efficiency. Our engineers redesign production equipment with improved components and systems while maintaining operational integrity during the modification process.
Bespoke Machinery
Our team designs and builds custom machinery solutions for unique production requirements. From concept to installation, we create specialised equipment tailored to specific industry needs while maintaining strict quality control throughout the manufacturing process.
