What This Part Is And Why It Is Made This Way
Some stainless parts are bought for shape rather than for strength: they locate other components, and their tolerance decides whether the machine runs true. These are machining led parts where the casting is only the starting blank.
Structures are cast in stainless grades and then machined, with 3D scanning available for complex surfaces and contours.
What You Get From This Route
3D scanning verifies contours that a caliper cannot check.
Machining allowance planned at the casting stage so critical faces always clean up.
Flatness measured as a specified inspection item.
Application Scenarios
- Machine locating and mounting structures
- Precision frames in processing equipment
- Instrument and inspection fixtures
- Hygienic equipment support structures
Who It Is For
- Equipment builders with tight assembly tolerances
- Buyers needing scanned dimensional evidence
- OEMs qualifying a new supplier for locating parts
Technical Features
- Stainless casting plus CNC machining
- 3D scanning for complex surfaces and contours
- Flatness and dimensional inspection
- Weight range 9 kg - 800 kg
What Buyers Run Into Without This Specification
- A complex contour is impossible to verify with hand tools.
- Critical faces do not clean up because the allowance was too small.
- Flatness is assumed rather than measured and assembly shims are needed.
Published Material Weight And Process Data
Figures below are the published capability for high alloy parts. Part specific values — tolerance on individual features, finish, packing — are confirmed at drawing review and marked TBC until then.
| Food Machinery Material | 1.4308 / 1.4309 / 1.4340 |
|---|---|
| Food Machinery Weight | 9 kg - 800 kg |
| Grate Bar Material | 1.4777 / 1.4776 / 1.4823 / 1.4743 / LH26 / EN-GJL-200 + 3%Cr |
| Grate Bar Weight | Typical products 2 kg - 50 kg; some grate bars and liners around 10 kg - 50 kg |
| Biomass Material | 1.4777 / 1.4776 / 1.4823 / 1.4855 |
| Working Temperature | Typical maximum around 1050 °C - 1150 °C depending on material and duty |
| Process | Shell moulding, lost wax and lost foam casting, plus CNC machining |
| Tolerance | Shell moulding normally CT9-10; lost wax normally CT8; surface roughness about Ra 12.5 |
| Part Specific Tolerance | TBC — confirmed against the customer drawing |
| Minimum Order Quantity | TBC — depends on the process route selected |
| Lead Time | TBC — confirmed with the production base at quotation |
How The Part Is Made And Checked
- Inspection — Dimensions, flatness, assembly clearance, 3D scanning, RT, PT, hardness, chemical composition and tensile testing.
- Material Control — Chemical analysis on each melt, sampling from the product body and third party testing for special elements.
- Heat Treatment — Rotors are annealed to 20-35 HRC before machining, then quenched at about 1020 °C to 59-63 HRC.
Quality management is based on ISO 9001 and covers supplier management, raw material inspection, production process control and final inspection. Inspection results are archived and traceable.
Options And Alternatives
Parts are produced to the customer drawing rather than to a fixed catalogue item, so material grade, machining scope, surface treatment and packing are all specified per order. Machining, dimensional control, surface treatment and necessary pre-assembly can be added to the same supply route.
Where another process family would suit the part better — for example a forging in place of a casting for a shock loaded connector — that comparison is raised during drawing review rather than after tooling is committed.
How To Specify This Part
Identify the datum structure and the functional surfaces on the drawing. Where contours are complex, ask for a 3D scan report at first article — it is far quicker to agree a colour map than to argue about a handful of measured points.
- Send the drawing with material, quantity, quality standard and target delivery date.
- State the inspection class and the zones it applies to, rather than a general note.
- Confirm the packing requirement and the lifting equipment available at the destination.
