Full-Spectrum Manufacturing Capabilities
Capabilities
From ultra-precise tubing, grinding, and cutting to glass blowing, sealing, coatings, and marking, we bring decades of mastery to every glass challenge so your project gets innovation with reliability.

Glass Blowing
Our skilled glassblowers can shape almost anything, either free hand or on lathes. The process supports the fabrication of parts that require integrated joints, material transitions, and finishing operations as part of a single build sequence.
Specifications
| Modality | lathe, freehand |
| Materials | glass, quartz |
| Sealing Types | glass-to-glass, glass-to-quartz, glass-to-metal |
| Post-processing | finishing options available |
Precision Bore Tubing
Precision Bore (or PB) tubing is SP Wilmad’s principal product and is manufactured to each industry’s strictest tolerances. Our stock of mandrels is extensive and, with our decades of experience, PB tubing can be produced for virtually any I.D., shape, or length.
Specifications
| Tubing Type | capillary, pyrex, quartz, square tubing |
| I.D. | as small 0.025mm |
| Wall Thickness | as small as 0.1778mm |
| Tubing Geometries | capillary, round, multi-bore, rectangular, square |


Precision Grinding & Cutting
We use precision grinding and cutting to bring formed components to their final dimensions. Our concentric and centerless grinding methods control outside diameter and wall thickness with the same high level of accuracy as our internal diameter work.
Specifications
| Grinding Types | concentric, centerless |
| O.D. Precision | ±0.00635 mm |
| Wall Thickness Control | controlled in concentric grinding |
| End Finishing Options | cut, fire polish, grinded |
Glass Tooling & Forming
Our in-house tooling and forming capabilities support complete apparatus, joints, and flanges from tube and rod stock. We offer vacuum silvering, glass-to-metal seals in a range of metals, and ultra-high vacuum jacketing and feedthrough assemblies.
Specifications
| Output | apparatus, joints, flanges |
| Vacuum & Seal Facilities | vacuum silvering, forming glass-to-metal seals |
| Seal Materials | tungsten, stainless steel, platinum |
| Specialized Processes | ultra-high vacuum glass jacketing, vacuum tube electronic feedthroughs |


Glass Treatment Processes
We offer specialty glass coatings and treatments to enhance durability, chemical resistance, safety, and performance. Options include UV light protection and safety coatings, as well as chemical strengthening for demanding environments.
Specifications
| Coating Types | UV inhibitor, low-actinic, amber, PVC safety coating, nylon safety coating |
| Strengthening Method | chemical strengthening |
| Pressure Performance | high pressure tolerance |
| Functional Effect | enhanced durability, performance |
Marking & Decoration
We produce graduated markings under temperature-controlled conditions to support accuracy, with optional decal programs, including sequential barcoding, used to provide permanent identification and traceability.
Specifications
| Methods | etching, silk screening |
| Identification Options | decals available, including sequential barcoding for permanent ID and traceability |
| Process Control | temperature-controlled conditions |
