Ultra precision heat and vacuum shrinking of glass and quartz tubing forms the core of Wilmad-LabGlass’s precision bore manufacturing operations. Tubing of various diameters up to 6 inches is shrunk to I.D. tolerances of up to +/- 0.0002 inch on precision stainless steel and molybdenum mandrels. We have both vertical and horizontal shrinking machines for precise product control over virtually any size tube in lengths up to 144 inches.
Concentric grinding, where both the O.D. and wall thickness are precisely controlled, and centerless grinding, where the O.D. is controlled, can be performed to the same precision tolerances as our I.D. work. Finishing can include polishing to highly precise optical tolerances as well as beveling, chamfering, ultrasonic drilling and wet saw cutting.
Our skilled glassblowers can shape almost anything, either free hand or on lathes. Facilities are available for vacuum silvering and forming glass-to-glass and glass-to-metal sealing.
Wilmad-LabGlass offers the talent, know-how and the equipment to do the job right the first time.
Additional capabilities include precision formed shapes for applications utilizing non-cylindrical glass components, high precision OD polishing for visible and UV applications and diamond band saw cutting and end finishing ensuring and maintaining rigorous length and perpendicularity tolerances.
Wilmad-LabGlass is ISO 9001:2008 registered and has a stringent quality control program that begins with inspection of incoming material and follows through every step of the manufacturing process. Microscopic inspection may be required to minimize inclusions and imperfections in the finished product.
To ensure tolerances are met, our QC inspectors use NIST calibrated micrometers, air gauges and other precision measurement equipment. Where required, items are also leak checked using our mass spectrometer.
