Custom Machined Calcium Silicate Shaped Parts

CNC Machining & OEM Fabrication to Your Drawings

When a flat board cannot solve your insulation challenge, we CNC-machine high density calcium silicate into precision shaped parts — discs, rings, cylinders, tubes, pipe sections and complex profiles — from 800–1200 kg/m³ grades, rated to 1100°C, to your exact drawings.

Why Factory-Machined

Factory CNC vs Field Cutting

🎯

±0.5 mm Precision

CNC holds ±0.5mm across hundreds of pieces; field cutting is ±2–5mm with rough edges.

♻️

No Material Waste

Factory nesting cuts the 30–40% scrap rate of cutting circles from boards on site.

Clean Edges

Smooth machined edges keep full strength — no micro-cracks that fail under thermal cycling.

📦

Consistent Quality

Order 500 identical parts and every piece arrives the same size and finish.

⏱️

Faster Installation

Pre-machined parts drop in and fit first time — no trimming or re-cutting on site.

🛡️

Non-Asbestos · 1100°C

A1 non-combustible, non-asbestos material across all machined grades.

How to Order

From Drawing to Delivery

1

Send Your Drawing

A sketch with dimensions is enough. CAD files (DXF/DWG/STEP) welcome for complex parts.

2

Review & Quote

We confirm the best grade and send piece price, tooling (if any), lead time and MOQ.

3

Sample Approval

For new shapes we typically produce 2–5 samples for your evaluation first.

4

Production & Delivery

15–25 day lead time, shipped with professional export packaging.

FAQ

Frequently Asked Questions

What custom calcium silicate shapes can you machine?
Discs, rings, cylinders, tubes, pipe sections, grooved and channeled parts, tapered and contoured profiles, and multi-feature components — all CNC-machined from 800–1200 kg/m³ high density calcium silicate.
What tolerance can you hold?
CNC machining holds tolerances as tight as ±0.5mm consistently across high-volume production — far better than field cutting (±2–5mm).
What is the minimum order quantity?
Typically 50–100 pieces depending on size and complexity; lower minimums are possible for simple shapes such as discs and rings.
Which grade is used for molten aluminum contact parts?
The 1020 kg/m³ grade is the standard choice for molten aluminum contact parts such as launders, dams, spouts and pouring components, thanks to its non-wetting surface.
Do you work from CAD drawings, and how is pricing determined?
Yes — send a sketch with dimensions or CAD files (DXF, DWG, STEP). Pricing depends on shape, size, grade, tolerance and quantity; send your drawing for a factory-direct quotation.
