Precision Ceramic Products & Components

Custom-manufactured in ZrO₂, Al₂O₃, SiC, Si₃N₄. Tolerances to ±0.001mm. MOQ 1 piece.

FineCer manufactures precision ceramic products for industrial buyers who need components that outlast metal in heat, corrosion, and abrasion — tubes, rods, plates, rings, plungers, valves, nozzles, and fully custom geometries. Every product line is available in all four advanced ceramics we run in-house — ZrO₂, Al₂O₃ (95–99.99%), SiC, and Si₃N₄ — and is finished on the same diamond grinding lines, to the same ±0.001mm tolerance and Ra 0.1μm surface standards, whether you order 1 prototype or 10,000 production pieces.

These limits are facility-wide, not product-specific: the same machines that polish a plunger to Ra 0.1μm lap a substrate flat and grind a nozzle bore round. Critical dimensions are verified by CMM in our quality control lab, and every shipment carries a measured inspection report against your drawing — not a generic certificate. Where a dimension matters to function — a sealing bore, a mating face, a located hole pattern — say so on the drawing; where it does not, a looser as-fired tolerance keeps the price down without touching performance. Our DFM review marks that split for you.

Built Around Custom, Not Catalog

Most pages in this section publish capability envelopes — diameter ranges, thickness minimums, tolerance floors — rather than fixed SKUs, because nearly every industrial ceramic part is application-specific. The fastest way to a price is therefore not browsing but sending a drawing: STEP, IGES, DWG, DXF, PDF, or a dimensioned sketch all work. Our engineers return a manufacturability review, a material and grade recommendation, and an itemized quote within 24 hours. If a standard geometry already in tooling fits your need, the quote says so and the price reflects it.

One Supplier for Every Ceramic Component

A typical machine build needs more than one ceramic: an alumina insulator here, a zirconia plunger there, a SiC seal face in the pump. Sourcing those from three specialized factories means three audits, three quality systems, and three shipping schedules. FineCer consolidates them — all four materials, every product family on this page, one ISO 9001:2015 system, one dedicated engineer per account — which is how 500+ projects across 40+ countries have kept >98% on-time delivery. Start with the category closest to your part, or go straight to custom ceramic parts if nothing matches; the material selection guide will help you shortlist the ceramic before you ask.

From Drawing to Delivered Part

Every product order follows the same seven-stage project management process with a dedicated engineer as your single point of contact. Typical lead times: standard-shape prototypes in 7–15 business days, complex injection-molded parts in 15–25 days, and volume production in 15–30 days depending on quantity and complexity — with 48-hour rush service available for standard geometries. Parts are packed for international transit and shipped worldwide; the 40+ countries we serve include long-running accounts in Europe, North America, Japan, and Korea. Before any volume release you can validate with samples from 1 piece, made on the same tooling, powders, and sintering curves as the production run — so the part you test is the part you will receive.

Frequently Asked Questions

Do you sell standard catalog parts or only custom?
Both, with custom as the core. Standard nozzle sizes and common ring/tube dimensions ship from established tooling, but most of our 500+ projects are built to customer drawings — that is what the ±0.001mm grinding capability and free DFM review exist for.
Which product pages should I start with?
Match the geometry first: tubes, rods, plates, and rings cover basic shapes, while plungers, valves, and nozzles are application-specific assemblies. Anything that fits none of those is a custom part.
Can the same part be quoted in more than one material?
Yes — and we recommend it when the duty is uncertain. Because all four ceramics run in-house, one drawing can return parallel quotes in, say, 99% alumina and Y-TZP zirconia, and you can sample both from 1 piece each.
What is the minimum order quantity for products?
1 piece, on any product type, via our prototyping service. Samples are made on production tooling and processes, so prototype performance predicts volume performance.
