Service Overview
YuanHang's high temperature heat treatment service helps customers test a material, compare process conditions and verify feasibility without immediately purchasing and maintaining a dedicated furnace. Customer-supplied samples are processed according to an agreed temperature, atmosphere or vacuum, holding time and cooling plan.
The service is intended for research institutes, universities, material developers and manufacturers carrying out sample testing, small-batch processing or pre-production validation. After testing, our engineering team can also discuss process scale-up and suitable furnace configuration when the customer is ready to move toward regular production.
Available Heat Treatment Services
Carbonization
Controlled carbonization trials for suitable carbon precursors and carbon-based materials under an agreed protective atmosphere or vacuum process.
High-Temperature Purification
Thermal purification evaluation for suitable graphite and carbon materials where elevated temperature may help reduce volatile or removable impurities.
Vacuum Heat Treatment
Sample processing under an agreed vacuum level using equipment selected according to material compatibility, temperature and process purpose.
Inert-Atmosphere Heat Treatment
Trial processing under argon, nitrogen or another technically confirmed atmosphere to reduce unwanted oxidation or support the required thermal process.
Process Verification
Comparative trials for carbon and advanced materials to support process selection, parameter refinement and future furnace specification.
Materials We Can Evaluate
Potential materials include the following. Acceptance depends on composition, safety information, sample form and the required process.
Graphite powder Graphite products Carbon materials Battery anode materials Carbon fiber Carbon felt C/C composites PI film or PI-derived materials Other advanced materials after review
Why Use a Trial Processing Service?
Verify the Process Before Equipment Investment
Evaluate temperature, atmosphere, holding time and material response before deciding whether to purchase a dedicated industrial furnace.
Access Industrial Furnace Capability
Use suitable high-temperature equipment without taking on furnace operation, utilities, cooling systems and routine maintenance.
Traceable Process Information
Available process records can be discussed before the order, including temperature data and agreed processing observations.
Confidential Project Review
Confidentiality requirements and an NDA can be discussed before samples and technical documents are submitted.
Flexible Small-Batch Evaluation
Suitable for R&D samples, proof-of-process work and small batches where dedicated equipment is not yet economical.
Return Packaging Options
Packaging requirements, including vacuum packaging where suitable, can be confirmed according to the processed material and shipping conditions.
Process Workflow
- Submit requirements: Send material information, sample dimensions, target temperature, atmosphere or vacuum, holding time and process purpose.
- Engineering review: Our engineers evaluate material compatibility, equipment availability, safety and process feasibility.
- Confirm the testing plan and quotation: Both parties confirm the processing route, sample quantity, schedule, available records and commercial terms.
- Receive and label samples: Incoming samples are checked and identified according to the confirmed project information.
- Perform heat treatment: Samples are processed according to the agreed plan using suitable furnace equipment.
- Record agreed process data: Available temperature, photo, video or process records are collected as confirmed before processing.
- Return samples and discuss scale-up: Processed samples are returned for evaluation, followed by discussion of further testing or furnace selection where required.

Information Required for a Processing Quote
To help our engineers assess the project, please provide:
- Material name, composition and safety data, if applicable
- Sample dimensions, quantity and total loading weight
- Target maximum temperature and holding time
- Required atmosphere or vacuum level
- Heating and cooling requirements
- Process purpose and expected result

- Return packaging requirements and destination country
Processing availability, lead time and quotation depend on material compatibility, equipment scheduling and the confirmed process route.
Send Your Processing RequirementsAvailable Process Records
Depending on the selected equipment and the agreement made before processing, available project records may include:
- Temperature data or exported temperature curve
- Photos of sample preparation, loading or processed samples
- Short process video where site and safety conditions allow
- Confirmed atmosphere, vacuum or holding-time information
- Basic processing observations agreed before the trial
Tell us which records you need before quotation. Records that are not confirmed in advance may not be available after processing.
Confidentiality and Sample Handling
Customer materials and process information are reviewed only for project evaluation and processing. NDA requirements can be discussed before technical documents or samples are submitted. Sample identification, return packaging and special handling requirements should be confirmed in writing before shipment.
From Sample Testing to Furnace Selection
Sample testing can help verify whether a proposed temperature, atmosphere, holding time and furnace configuration are suitable before a larger investment. If the trial supports further scale-up, YuanHang can discuss working zone size, loading capacity, heating method, process atmosphere, utilities and control requirements for a custom industrial furnace.
Frequently Asked Questions
Can YuanHang process only one or a few samples?
Yes, individual samples and small batches can be evaluated when they are compatible with available equipment and the proposed process.
What materials can be tested?
Potential materials include graphite, carbon materials, carbon fiber, PI-derived carbon materials, suitable ceramics, powder metallurgy materials and other advanced materials. Every project requires an engineering and safety review.
What is the maximum available temperature?
Available temperatures can reach up to 3100°C for technically suitable and confirmed projects. The appropriate maximum temperature depends on the material, furnace configuration, atmosphere or vacuum, sample size and process purpose.
Can you process samples under vacuum or inert gas?
