Quartz glass repair
Quartz glass repair
Quartz glass products are usually cost-intensive.
For this reason, repair is often a good alternative to buying new.
Repair – or new?
This question we answer you after sighting the damaged equipment or the damaged part gladly. You will quickly receive a cost estimate from us and, if necessary, an assessment regarding the profitability of a repair.
Service
Prolong the life of your quartz glass apparatus with regular service.
We are happy to perform regular service on your equipment – this includes cleaning (removing material deposits) and/or sealing scratches with fire polishing.
Ask us – we will gladly make you an offer.
Cleaning and acidifying quartz glass
Cleaning and acidifying quartz glass
Hydrofluoric acid, or HF acid, is used to etch quartz glass and, depending on the concentration, can be used both for cleaning, bright etching or matting. It is the most commonly used etchant in semiconductor production, where it is used to remove silicon dioxide, among other things. Deposits and fume are produced when fused quartz is processed. Immersion in a vat of hydrofluoric acid removes these impurities – resulting in a high-purity quartz glass product.
Anneal quartz glass stress free
Anneal quartz glass stress free
The glass is heated high-but below the melting temperature-now atoms can move into position.
This process creates stress-free fused silica.
Evacuate quartz glass components
Evacuate quartz glass components
Evacuating (extracting the air from a hollow chamber) is used to improve thermal insulation- e.g., in double-walled vessels.
By applying a vacuum pump, air is pumped out of the double jacket, when this process is completed, the jacket is sealed.

Marking quartz glass
Marking quartz glass
Placing glass inscriptions ensures a permanent marking of the product.
.
Such lettering is heat and acid resistant.
The inscription is applied to the product by hand with a glass rod.
Quartz glass construction
Construction of quartz glass apparatus and components
We are your partner from planning to design and manufacturing of quartz glass components and apparatus.
We design (3D CAD SolidWorks) your solutions – single pieces or also production optimized for serial productions.

Hot processing
Diameter expansion
Diameter expansion
Molding of NS ground joints, funnels, flanges and customized special designs.
.
It is also used for hot forming into a negative mold (molding tool made of graphite).
Quartz glass welding
Quartz glass welding
Welding of quartz glass elements enables the production of complex and precisely fitting components.
Quartz glass bending
Quartz glass bending
Bending is done by hand.
Typical products include oven forks and spirals.
Quartz glass attachment
Quartz glass attachment
Mounting is the joining of two glass tubes by means of the flame.
Attachment also allows two tubes of different diameters to be joined together, also NS cuts can be attached to a different tube diameter.
Quartz glass fire polishing
Quartz glass fire polishing
Grounded or cut surfaces are reglazed in the flame.
.
This smoothes out slight surface damage and rounds off cuts.
Glassblowing
Glassblowing
This work includes blowing quartz glass into molds – from which, for example, crucibles and lids are made.
Glassblowing work also includes the manual production of typical glassblowing products by hand – often for very individual productions.

Cutting quartz glass
Cutting quartz glass
Glass products are cut to the right size on a grinding cutting machine.
Quartz glass grinding
Quartz glass grinding
On a rotating faceplate, special abrasives are used with the addition of water, e.g., to grind a bottom, clean edges or grind flat surfaces (flange).
NS grinds are ground in on a rotary grinding machine for accuracy of fit.

Quartz glass water jet cutting
Quartz glass water jet cutting
With waterjet cutting, the material is separated by a high-pressure water jet (up to 6,000 bar).
This cutting process is gentle on the material and allows for very flexible shaping.
