01Drawing preparation guide
Prepare a clear ceramic fiber part drawing with material, temperature, critical dimensions, tolerances, openings, interfaces, quantity and revision data.
02Overview
Mark the material grade, operating temperature, critical geometry, interfaces, tolerances, surface requirements, units and drawing revision. Unknown values can be identified clearly for discussion before quotation.
03Technical information
A useful ceramic fiber drawing identifies the component, operating conditions, critical geometry, mating interfaces, tolerances, openings, surface requirements, revision and quantity. Mark unknown values clearly instead of estimating them.
Use enough orthographic, section and detail views to define the part without hidden geometry. Dimension the hot face, outer envelope, bores, wall thickness, openings, grooves and locating surfaces from stable reference points.
State the product family or required function, normal and peak temperature, atmosphere, cycling and mechanical exposure. If grade or density is unknown, mark it as not yet selected and provide the operating conditions.
Identify features that mate with metal shells, process tubes, elements, sensors, doors, anchors or other insulation. Apply tolerances only where fit or assembly requires them, and distinguish critical values from references.
Show the drawing number, revision, units, quantity and prototype or production stage. State whether the quotation should include machining, elements, shells, inspection records or export packing.
04Selection table
The checklist separates dimensions already defined on the drawing from tolerances, interfaces and inspection items that still require agreement.
| Drawing area | Include | Avoid |
|---|---|---|
| Identity | Part name, drawing number, revision, units and quantity | Files with no revision or unit system |
| Geometry | Overall size, internal size, wall thickness, bores and sections | Relying on photographs for hidden dimensions |
| Interfaces | Mounting, mating, elements, leads, sensors and openings | Treating connected equipment as outside the drawing |
| Tolerances | Critical-to-fit values and reference datums | Applying tight tolerances to every dimension |
| Operating conditions | Temperature, atmosphere, cycle and mechanical exposure | Selecting material from temperature alone |
| Included components | Forming, machining, surface, heating, shell and records | Leaving supplied parts and buyer-installed parts unspecified |
05Product selection steps
A revision-controlled drawing gives engineering, manufacturing, inspection and purchasing the same dimensions and interfaces.
Identify the equipment, insulation role, operating conditions and the parts required from SYNTHE.
Add views, sections, dimensions, interfaces, openings and critical tolerances.
Call out material, density, surface or electrical decisions that still need to be confirmed.
Check the drawing number, units, prototype or batch quantity and required documents.
08Technical FAQ
You can send a 2D PDF or CAD drawing, STEP model, marked sketch, measured sample or clear photographs. Critical dimensions are recorded before custom production.
No. Mark the dimensions that control fit, assembly or function. Unnecessary tight tolerances can add cost without improving the application.
Describe the operating temperature, atmosphere, cycle, component dimensions and mechanical exposure, and mark grade or density as not yet selected.
Yes. The drawing can include the ceramic body, elements, leads, terminals, sensors, shell, brackets and other required interfaces.
10Specification support
Include datums, critical tolerances, holes, grooves, surface treatment, material grade, density and the intended mating or installation condition.
