What This Part Is And Why It Is Made This Way
An assembly is only as good as the fit between its parts, and when those parts come from different suppliers nobody owns the fit. Buying the assembly instead of the pieces moves that responsibility to one place.
Assembled machinery components are cast, machined and pre-assembled within the same supply chain, with assembly clearance checked before delivery.
What You Get From This Route
Parts arrive as a checked assembly rather than as components to be matched on site.
Assembly clearance is inspected as a delivery requirement.
One supplier is responsible for the fit, not three.
Application Scenarios
- Pre-assembled food machinery modules
- Hygienic conveyor sections
- Processing equipment sub assemblies
- Replacement modules for installed lines
Who It Is For
- OEMs reducing the number of part numbers they buy
- Plants that want a drop in replacement module
- Integrators without in house assembly capacity
Technical Features
- Casting, machining and necessary pre-assembly
- Stainless grades to drawing
- Assembly clearance inspection
- Supply chain coordinated under one project
What Buyers Run Into Without This Specification
- Components fit the drawing individually but not each other.
- Assembly work at the destination costs more than the parts.
- Responsibility for a bad fit is disputed between suppliers.
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
Send the assembly drawing as well as the part drawings, and state which clearances are functional. Necessary pre-assembly can be included in the scope, which is usually the cheapest place to catch a fit problem.
- 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.

Do you supply pre-assembled units or only single parts?
Machining, dimensional control, surface treatment and necessary pre-assembly services are part of the product capability, so assemblies can be supplied.
How is the fit between parts verified?
Assembly clearance is one of the standard inspection items for this business, alongside dimensions and flatness.
What do you need to prepare a quotation?
Drawings, material, quantity, quality standard and target delivery date.
Which inspection is included?
The inspection scope is agreed during drawing review. Rotors are annealed to 20-35 HRC before machining, then quenched at about 1020 °C to 59-63 HRC.
