RFQ Checklist
- Mold drawing or target molded part geometry
- Process temperature, cycle time, and contact material
- Surface finish target and release coating requirement
- Prototype quantity, spare part demand, and destination
Precision graphite molds and die components for glass forming, hot pressing, sintering, casting, and laboratory thermal processes.
Complete RFQs are easier to review within 1-2 business days when drawings, graphite grade, quantity, and destination are included.
| Option | Best Fit | Watchouts |
|---|---|---|
| Fine-grain isostatic graphite mold | Precision cavity details, glass forming, hot pressing, and tooling where release surface and edge definition matter. | Review thin ribs, sharp cavity corners, and polishing or coating expectations before machining. |
| Molded graphite mold or plate | Larger mold plates, casting supports, sintering tooling, and thermal fixtures with moderate detail requirements. | Confirm temperature gradient, contact material, load, and replacement interval to avoid short cycle life. |
| Treated or high-purity graphite mold | Processes sensitive to oxidation, contamination, sticking, or release behavior. | Specify treatment, cleaning, packing, and certificate expectations before order release. |
Review target part geometry, mold split, cavity details, shrinkage assumptions, and fragile mold edges.
Match grade or treatment to temperature, atmosphere, contact material, release behavior, and expected replacement cycle.
Machine cavity features with graphite-specific dust control and protect thin ribs, vents, slots, and sharp details.
Check critical cavity dimensions, flatness or parallelism where specified, then protect corners and contact faces for shipment.
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Operating temperature | Process-dependent high-temperature service | Temperature and atmosphere drive grade choice, oxidation risk, and expected service life. |
| Feature protection | Edge radius and packing agreed per drawing | Graphite mold details can chip if packing and handling are not planned. |
| Contact and release condition | Glass, metal, ceramic, powder, or lab thermal media | The contact material affects grade choice, treatment need, cavity finish, and mold service life. |
Yes. Prototype graphite molds are common for process development. We can quote small batches and then keep the geometry ready for repeat orders.
Send the finished part drawing, process temperature, contact material, shrinkage assumptions, and desired mold life. We can help define the mold RFQ package.
Yes. Grade selection starts from operating temperature, atmosphere, contact material, cavity detail, release requirement, and expected mold life. Existing failed-part photos are also useful.
