Buyer Decision Map
Match the carbon material to the process risk first
Semiconductor buyers usually need more than a drawing quote. The starting point is the thermal environment, contamination risk, SiC or TaC coating exposure, load case, and replacement schedule.

Vacuum Furnace
C/C Composite Structures
Load-bearing carbon hardware

Custom Range
What can be customized before sample production
The scope is not limited to shape. We clarify material selection, coating, surface condition, CTQ dimensions, records, packaging, and commercial delivery path before releasing a first article.
Material and Blank Selection
High-purity isostatic graphite, purified graphite, C/C composite, rigid carbon felt, and SiC coated graphite selected by process risk.
Drawing-Based Machining
2D drawings, 3D CAD, sample photos, or reverse-engineered replacement parts can be reviewed for CTQ dimensions and tolerances.
Coating and Surface Scope
CVD SiC coating thickness, pocket finish, sealing faces, threaded areas, chamfers, and clean handling requirements are defined up front.
Packing and Export Setup
Vacuum bagging, foam nests, moisture control, export crating, and DDP/FOB terms are planned around part fragility and schedule.
Quality Control
Controls buyers ask for before they approve repeat orders
For critical graphite and SiC coated components, the quote must connect to practical inspection evidence, not only catalog descriptions.
Purity Control
Ash and trace-metal expectations can be scoped for semiconductor programs, including ICP-MS reporting when required.
Dimensional Inspection
Critical dimensions, flatness, pocket depth, OD/ID, threads, and assembly interfaces are aligned before production release.
Coating Verification
SiC coated components can be checked for coating thickness, visible defects, edge coverage, and surface condition.
Shipment Protection
Fragile graphite, coated parts, and C/C fixtures are packed with handling labels, inserts, and export-ready documentation.

Sample to Batch
A clear path from engineering review to repeat supply
Lead time depends on machining complexity, purification, SiC coating, C/C fabrication, inspection records, and export packing. We separate sample risk from batch planning so buyers can qualify parts without guessing the production route.
