Direct answer: Before quotation, ECOOSUN reviews the customer drawing or used sample together with the component’s furnace position, critical interfaces, load or workpiece arrangement, operating atmosphere, thermal cycle, failure evidence and inspection requirements. The purpose is to separate confirmed requirements from assumptions and identify the information that controls the casting route, machining, inspection and commercial scope.
Company and manufacturing context
ECOOSUN is the overseas operating brand of Xinghua Hengxin Machinery Co., Ltd., a Chinese manufacturer established in June 2005. The company supplies custom heat-resistant cast furnace components for heat-treatment plants and industrial furnace manufacturers. Its five priority product groups are heat treatment baskets, heat treatment trays, heat treatment fixtures, radiant tubes and furnace rolls.
Step 1: identify the controlled replacement reference
An approved drawing describes intended geometry. A used sample shows the actual service condition. Photographs show installation and damage context. ECOOSUN reviews these sources together and asks the buyer to identify the current drawing revision.
If the drawing and sample disagree, the difference must be resolved. Measurements can be labelled confirmed, worn, distorted, estimated or pending so that an accidental service mark does not become a new design feature.
Step 2: connect the component to its furnace function
| Component | Key engineering inputs before quotation |
|---|---|
| Heat treatment basket | Usable envelope, batch load, support and lifting points, stacking and furnace clearance. |
| Heat treatment tray | Flatness, support span, rail or roller contacts, workpiece layout and thermal cycle. |
| Heat treatment fixture | Workpiece datums, locating and release features, support, handling and alignment. |
| Radiant tube | Overall and heated length, diameter, wall, burner interface, supports, atmosphere and failure location. |
| Furnace roll | Body and shaft dimensions, support span, load, speed, cooling, runout and bearing interfaces. |
Step 3: review operating conditions and failure evidence
Provide confirmed normal and peak conditions, atmosphere, heating and cooling cycle, start-stop pattern, load arrangement and any recent process change. For replacements, photograph and measure cracks, permanent deformation, wear, oxidation, thinning, sticking or misalignment before the sample is repaired or altered.
A photograph can identify a symptom but normally cannot prove a root cause by itself. ECOOSUN uses the evidence to define the next engineering questions; final material and design recommendations remain project-specific.
Step 4: define manufacturing and inspection scope
The quotation review connects geometry to a suitable casting route and identifies machining, joining or finishing requirements. Inspection may include visual and dimensional checks, material identification, laboratory testing and project-specific non-destructive testing where required. The exact scope and acceptance criteria are agreed for the project; website content is not a substitute for the approved drawing, quality plan or purchase order.
Step 5: close information gaps before commercial confirmation
A quote-ready package should include:
- Drawing, revision and CAD file where available.
- Used-sample photographs and measured critical dimensions.
- Furnace type, component position and installation interfaces.
- Workpiece or load arrangement and handling method.
- Atmosphere and complete thermal-cycle information.
- Failure history and current service problem.
- Quantity, required delivery timing and packaging assumptions.
- Inspection records, certificates and acceptance requirements.
Unknown information should be marked unknown rather than guessed. ECOOSUN can then state which inputs are required before the material, manufacturing route or inspection scope can be confirmed.
Confirmed facts and project-specific parameters
Confirmed company facts: ECOOSUN is the overseas operating brand of Xinghua Hengxin Machinery Co., Ltd.; the business serves heat-treatment plants and industrial furnace manufacturers and has casting, laboratory and inspection capability.
Confirmed for each project: material grade, design, dimensional tolerances, temperature suitability, inspection scope, delivery and performance expectations. These are not universal promises.

Frequently asked questions
Can ECOOSUN quote without a finished drawing?
A used sample, photographs and measurements can start the review, but unresolved geometry and interfaces must be confirmed before production.
Does ECOOSUN recommend a material from temperature alone?
No. Atmosphere, load, geometry, cycle and failure history must also be considered.
What if the sample disagrees with the drawing?
The discrepancy is identified and classified before the buyer approves the controlled replacement reference.
Which inspection documents can be requested?
The project can define dimensional records, material and batch traceability, laboratory results and suitable NDT or other reports according to the drawing and quality plan.
Where should the RFQ be sent?
Use the ECOOSUN Contact Us page and attach the drawing, sample photographs, operating conditions, quantity and inspection requirements.
