A three-layer blown film die block, from the billet that came in on a pallet to the assembled die. One job, nine photographs, in order. More on extruder components.
Spiral mandrels, die bodies, flange rings and distribution plates machined from 4140HT and stainless for blown film and sheet extrusion lines. More on extruder components.
Feed screw modification, adapters and journal work for single and twin screw extruders, cut on the mill-turn in one setup where the geometry allows. Breaker plates drilled in 15-5 PH stainless. More on extruder components.
Gearboxes stripped, measured, line-bored in house and re-timed. Bearings and seals run one to two weeks; a full rebuild four to eight. More on industrial gearbox repair.
Boring, facing and drilling on parts too big for a lathe — we lift to 10 tons and line-bore to 20in diameter across a 50in span. More on large part machining.
Production runs, small batches and one-offs machined to a customer’s drawings, every piece the same as the last. More on CNC turning.
Shafts turned between centres and carried in the steady rest, with keyways, splines and threads cut on the same setup. More on shaft machining.
Bore honing on the Sunnen, for finish and size on cylinders, sleeves and liners. More on bore honing.
Weldments machined after welding, and finished parts crated and delivered on our own truck. More on large fabrication.
