Quartz fabrication capabilities

Quartz is a process-sensitive material. The same component can succeed or fail depending on how it is formed, machined, and finished. We coordinate the appropriate process route with qualified manufacturing partners — and explain where each method fits.

Quartz process review and measurement
DRAWING-BASED REVIEW

From measurement to process judgment.

01 · Flame Working

High-temperature quartz forming by experienced craftsmen — including flame polishing, tube bending, flaring, sealing, and custom shaping. Depending on geometry, dimensional control is typically around ±0.1 mm. Best suited to specialty lab glassware, prototype components, and small-batch custom parts where shape matters more than volume.

02 · CNC Machining

CNC grinding, cutting, and machining for tight, repeatable tolerances. For suitable geometries, critical dimensions can typically be held to ±0.05 mm. Tighter tolerances require drawing review and agreement on inspection methods. Suited to tubes, rods, plates, and complex geometries that need to match a drawing precisely.

03 · Polishing & Finishing

Surface finishing methods selected according to the component and application. Depending on the requirement, this may include mechanical polishing, optical polishing, or fire polishing. Surface-quality targets are reviewed against the drawing, material grade, geometry, and inspection method.

04 · Custom Assembly

Multi-component quartz assemblies joined by fusion welding. Leak testing can be arranged where sealed integrity is part of the specification. Suited to builds that combine several formed and machined parts into one finished component.

Typical review envelope

Typical ranges.
Clear limits.

The figures below are practical starting points, not blanket guarantees. Final feasibility depends on material grade, geometry, process route, quantity, and the inspection method agreed before quotation.

01 / Starting ranges

Typical project starting points

  • Tubes & rods Selected tube and rod projects commonly start within an OD range of Ø1–Ø200 mm. Larger or non-standard assemblies are reviewed separately.
  • CNC-machined dimensions For suitable geometries, critical dimensions can typically be held to ±0.05 mm. Tighter requirements need drawing review.
  • Flame-worked dimensions Depending on geometry, dimensional control is typically around ±0.10 mm.
  • Order format Samples, prototypes, and small batches can be reviewed before repeat production.

02 / Limits to confirm

Not every tolerance applies everywhere

  • Geometry matters Long lengths, large diameters, thick walls, thin walls, deep holes, and multi-part assemblies are reviewed case by case.
  • Formed surfaces vary Fire polishing and flame forming may introduce process-related variation. Functional and cosmetic criteria should be clarified early.
  • Optical requirements are separate Flatness, parallelism, surface quality, coating, and transmission targets are never assumed from a general machining tolerance.
  • Material grade is part of the specification OH level, trace-metal limits, contamination control, and documentation requirements should be confirmed before quotation.

03 / Inspection options

Inspect what the application requires

  • Drawing-based dimensional inspection Defined critical dimensions can be checked against the approved drawing.
  • Visual surface review Bubbles, striae, surface condition, and workmanship criteria can be reviewed according to the application.
  • Measurement methods CMM, surface roughness testing, flatness testing, and other methods can be arranged where the geometry and specification require them.
  • Sealed integrity Leak testing, including helium leak testing where required, can be arranged for sealed assemblies.
  • Records & documentation Inspection records and available material documentation can be provided for defined critical requirements.

A capability range is only a starting point. Final acceptance criteria, inspection scope, and documentation requirements are confirmed case by case before production.

What we don’t do

We don’t pretend to do everything. If your requirement falls outside what our partners do well, we’ll tell you plainly — and where we can, point you toward someone who’s a better fit. A capability list is only useful if it’s honest about its edges.

Have a specific requirement?

The best way to know if we can help is to show us. Send a drawing, a sample photo, or just a description of what the part needs to do.
