What This Part Is And Why It Is Made This Way
Operating parts are touched by people or by mechanisms, so they are judged on feel and fit rather than on raw strength. A lever that binds is rejected even if it is twice as strong as it needs to be.
Shafts and operating components are precision cast to CT5 - CT9 and finished where the interface demands it.
What You Get From This Route
Close as cast tolerance reduces the machining needed on interface features.
Consistent geometry keeps operating feel the same across a production run.
Wide grade choice from stainless to quenched and tempered steels.
Application Scenarios
- Valve and equipment operating levers
- Actuating spindles and handles
- Adjustment and locking mechanisms
- Machine control components
Who It Is For
- Equipment builders with operator facing parts
- Valve and fitting manufacturers
- Designers reducing part count in a mechanism
Technical Features
- Silica sol lost wax process
- Materials 1.4304 / 1.4308 / ASTM 8620 / 2Cr13 / 20Mn5 / 42CrMo4 / S355
- CT5 - CT9 tolerance
- Weight 0.01 kg - 300 kg
What Buyers Run Into Without This Specification
- Machined levers are expensive for what is essentially a shaped part.
- Operating feel varies between production batches.
- Several small pieces are assembled where one casting would do.
Published Material Weight And Process Data
Figures below are the published capability for precision casting. Part specific values — tolerance on individual features, finish, packing — are confirmed at drawing review and marked TBC until then.
| Material | 1.4304 / 1.4308 / ASTM 8620 / 2Cr13 / 20Mn5 / 42CrMo4 / S355 |

How The Part Is Made And Checked
- Merged Scope — The precision casting scope now includes the former investment casting business, so one route covers both silica sol lost wax and quick-drying investment casting.
- Application Fit — Parts where appearance, assembly and dimensional consistency are demanding.
- Materials Covered — Carbon steel, low alloy steel, stainless steel and quenched and tempered grades.
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 interface features — the bore, the flats, the pivot — and let everything else stay as cast. That division is where precision casting saves the most money, because the process is accurate enough that only the interfaces need touching.
- 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.

Can several parts be combined into one casting?
Often yes. Precision casting is suited to complex structures where appearance, assembly and dimensional consistency matter, which frequently allows an assembly to be replaced by one part.
Which materials are available?
1.4304, 1.4308, ASTM 8620, 2Cr13, 20Mn5, 42CrMo4 and S355 among others, confirmed against the drawing.
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. Carbon steel, low alloy steel, stainless steel and quenched and tempered grades.
