Vertically Integrated · Powder to Part

Built In-House,
From Powder to Part.

We synthesize our own Si₃N₄ and ZrO₂ powders, dry-press / iso-press / slip-cast / injection-mold to near-net shape, sinter at 1700°C, and finish-grind to ±0.005 mm tolerance — all under one roof. No subcontracting. No surprises.

01 · 4 Capability Pillars

What we control, in-house.

Most ceramic component vendors trade. We make. Every ceramic component we ship is the result of these four capability pillars operating under one factory roof — which is why we can quote DFM in 48 hours and ship samples in 7–14 days.

🔗
Vertical Integration
Powder → Part

We synthesize our own Si₃N₄ and ZrO₂ ceramic powders, then forming, sintering, and machining happen on lines we operate ourselves. No third-party powder dependency. Full lot traceability from raw nitrogen and silicon feedstock through finished SKU.

  • In-house powder synthesis — Si₃N₄ and ZrO₂ to ≥99.5% purity
  • Full process traceability — Lot certs link back to raw material batch
  • No subcontracting — Every step performed by our team

Rapid Prototyping
★ Industry Lead

Most ceramic suppliers quote 6–12 weeks for a single prototype. We do stock geometries in 1–3 working days, custom drawings in 5–20 days — backed by dedicated DFM engineers who review your STEP / PDF / DWG within 48 hours and reply with feedback before quoting.

  • Stock samples — 1–3 working days dispatch
  • Custom prototypes — 5–20 working days (geometry-dependent)
  • DFM engineer support — 48-hour drawing review with feedback
  • NDA available — Signed before drawing review on request

Quality Control
ISO · IATF

ISO 9001:2015 quality management baseline, IATF 16949:2016 for automotive-grade production runs. Lot-specific test certificates issued on every production shipment — covering density, dimension, surface finish, and electrical/thermal properties as applicable.

  • ISO 9001:2015 certified quality system
  • IATF 16949:2016 for automotive production
  • Lot certs included — Density · dimension · property tests
  • Failure mode analysis — Available on request

Manufacturing Process
4 Stages

Four production stages: powder preparation, near-net forming (dry press / iso press / slip cast / injection molding / tape casting), high-temperature sintering (1600°C+ for structural ceramics), and post-sinter finishing (grinding, drilling, polishing).

  • Powder Preparation — Synthesis · blending · drying
  • Forming — Dry press · iso press · slip cast · injection · tape cast
  • Sintering — 1600°C+ electric, gas, oil furnaces
  • Finishing — Diamond grinding, drilling, lapping, polishing

02 · Rapid Turn-Around Ceramic Parts

Built for rapid turn-around.

The legacy ceramic industry quote — 6 to 12 weeks for a sample — is the single biggest reason engineering teams default to metal or polymer when ceramic would actually be the right material. We built our prototype line specifically to break that cycle.

Working Days

Stock Sample Dispatch

For any geometry already in our SKU catalog — igniters, balls, rods, plates, standard bearings — we dispatch from Hangzhou warehouse within 1–3 working days of order confirmation.

5–20
Working Days

Custom Prototype

For drawings (STEP / PDF / DWG), our prototype line produces 1–5 units in 5–20 working days depending on geometry complexity, material selection, and finishing requirements.

Engineer Response

DFM Engineer Support

Every drawing goes to a dedicated DFM engineer who reviews manufacturability, material selection, and tolerances — replying with feedback and quote within 48 hours of receipt.

03 · Manufacturing

From raw powder to finished part.

Four production stages, all in-house. The forming method we pick depends on geometry — small precision parts go through injection molding, large rotational parts through iso pressing, thin substrates through tape casting.

STAGE 01
⚗️
Powder Preparation

Si₃N₄ and ZrO₂ synthesis, plus blending of additives and binders. Particle size distribution and surface area controlled to spec.

Synthesis · blending · drying
STAGE 02
🔨
Forming

Near-net shape forming via dry pressing, isostatic pressing, slip casting, tape casting, or injection molding — chosen to match geometry.

Dry / iso press · slip · tape · injection
STAGE 03
🔥
Sintering

High-temperature densification. Structural ceramics typically sintered at 1600°C; functional ceramics at precision-controlled lower temperatures.

Electric · gas · oil-fired furnaces
STAGE 04
💎
Finishing

Post-sinter machining — diamond grinding to tolerance, drilling, lapping, and polishing to final surface finish specifications.

Grind · drill · lap · polish (Ra 0.2 μm)
★ Quality Numbers · 2025 Production

Quality you can audit.

A ceramic manufacturer's real quality is in lot rejection rates, on-time delivery, and how fast field issues get root-caused. Here's what 2025 looked like for our top-100 OEM accounts.
