Custom graphite molds, inserts, supports, and hot-bending tooling for curved cover glass, display glass, and precision thermoforming programs.
Complete RFQs are easier to review within 1-2 business days when drawings, graphite grade, quantity, and destination are included.
| Option | Best Fit | Watchouts |
|---|---|---|
| Two-piece hot bending mold | Straightforward curved glass programs where upper and lower mold surfaces define the main forming geometry. | Parting line, venting, and glass release details should be reviewed before machining begins. |
| Three-piece or insert mold | Programs needing local pressure, side support, replaceable inserts, or revision-friendly tooling. | Insert fit, thermal clearance, and assembly marking must be controlled to avoid trial confusion. |
| Multi-cavity or carrier tooling | Higher-throughput forming trials where multiple glass pieces or support pockets share one graphite fixture. | Large graphite tooling needs fixture planning, flatness review, and reinforced packing for export shipment. |
Review glass geometry, mold split, contact surfaces, venting, support points, and likely trial adjustments.
Select graphite grade and adjust fragile ribs, radii, grooves, and datum strategy for graphite machining.
Machine mold surfaces, inserts, supports, and assembly references with inspection photos and dimension checks.
Separate graphite contact surfaces, protect corners, label assemblies, and document packing for international shipment.
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Mold architecture | Two-piece, three-piece, insert, support, or multi-cavity design | The mold split and assembly approach control machining cost, trial adjustment, and glass release risk. |
| Surface expectation | Buyer-specified graphite finish and glass-contact acceptance | Surface quality affects glass marks, release behavior, and whether trial polishing or adjustment is needed. |
| Revision tolerance | Prototype mold, trial revision, or repeat production tooling | Early-stage glass forming programs often need repair allowance and clear revision records. |
A glass model helps, but mold design still needs forming process assumptions, stack-up, venting, support, and trial adjustment details.
The choice depends on surface requirement, mold size, thermal cycling, machining detail, and budget. Fine-grain graphite is often reviewed first for precision tooling.
Use revision-controlled drawings, marked photos, and clear notes on polished or reworked surfaces before ordering the next batch.
