From Pattern to Balanced, Inspected Part
Six capability groups covering the whole route. The first — the interface review — is where most replacement-part projects are won or lost.
Twin Vertical-Line Sand Casting
Sand moulding on a twin vertical-line system covered by a national patent. One route, run properly — mould after mould at the same density, which is what makes a batch repeat.
- Twin vertical-line moulding — national patent
- Spectrometer check on every heat
- Pattern and core boxes produced in-house
- Envelope and section thickness reviewed before quoting
CNC Machining
Machining of mating faces, seal seats, bores, registers and bolt patterns — the operations that turn a raw casting into a part that drops into a pump.
- Flange and mating faces machined flat
- Bearing bores and registers held to print
- Seal seats and gland faces finished
- First article measured before series release
Tooling & Engineering
Reverse-engineering from a worn sample, pattern design and the interface review that decides whether a replacement part actually fits.
- Interface-first review before quoting
- Assumed dimensions written onto the quotation
- Pattern and core box design and manufacture
- Hydraulic profile reconstructed from eroded samples
Quality & Testing
Every rotating part is balanced and every heat is verified. What ships is a part plus the paperwork that proves what it is.
- Dynamic balancing to the grade agreed on the order
- CMM dimensional reports
- PMI and spectrometer analysis
- DPI / RT non-destructive testing on request
Surface & Post-Processing
Heat treatment and finishing bring the alloy to its specified condition and the surface to the state the service requires.
- Solution annealing, quench and ageing
- Shot blasting and vibratory finishing
- Passivation of stainless components
- Polishing of vane and seat surfaces
Supply & Delivery
Production batches run on the twin vertical-line system, with the documentation package agreed before the first shipment.
- Minimum order quantity 100 pieces
- Casing and cover cast and machined as a pair
- EN 10204 3.1 certification per heat
- Export packing for sea and air freight
