Glassware
A VELVET HAND
IN AN IRON GLOVE
The world of glassmaking is very specific and we had to listen to you and then use all our know-how, our experience and our mastery of raw materials to innovate by being the first to offer a NefaGlass® range of flexible metal products intended for all industries which shape glass in any way whatsoever (hand-blown glass, mechanically, laminated, drawn or spun glass, coloured, white or even black, cosmetics, perfumery, crystal, bottle, large containers, tableware, glass blocks, windshield, glazing, ampoules, syringes, optics, mirrors, etc.).

Gripping Contact
(Suction pads, mechanical extraction clamps, clamps and manual release forks, etc.)
- Suction pads : Guaranteed optimum vacuum without preheating while maintaining the integrity of the product
For decades we have been supporting the greatest tableware glassware, adapting to new sizes, shapes, weights, colours, changes in materials and various innovations.
- Easily adapts to existing equipment
- No glass marking thanks to a "soft" contact
- Excellent thermal and mechanical resistance
- Unmatched lifespan
Specific contacts
(Forming-bending, banderillas, transport baskets, etc.)
- No thermal shock or marking at contact points
Another very delicate phase during which the glass must not undergo any thermal shock with the support/skeleton on which it will take its final shape.
- Limits thermal shocks
- Perfectly adapts to existing equipment
- No glass marking thanks to a "soft" contact
- Excellent thermal and mechanical resistance
Sealing of axles (top roll and camera) on float surface
(Reduces hydrogen outflow and oxygen ingress, avoiding tin haze marking on the glass surface.)
Customized bellows, adapted to your production tool.
-
Optimize maintenance of TIN COUNT value within standards.
-
VS Stainless steel bellows :
-
Accept larger working angles
-
Increased service life and sealing quality.
-
-
High-temperature (1000°C) textile on the hot side, resistant to flashback compared to conventional textile, and siliconized on the cold side to protect against external elements.
-
Fast fastening thanks to textile loops for long-term hold.
Example enclosed: 70 m long float furnace producing approx. 530 tons of glass/dayFurnace temperature 1100°C / Tin bath temperature 1000°CFlat glass throughput: 5 to 20 m/min depending on glass thickness.Installation of 28 bellows on all axes

Fire protection rope lagging
Normally subject to ambient temperatures, the building sector has the obligation to provide "passive protections" in the event of fires in order to delay their spread and protect citizens and structures (buildings, safe rooms, tunnels, airports, electrical box, shopping centres, public buildings, etc.).
Of French production, the regularity of our fire-resistant rope lagging as well as our reactivity have been unanimously recognised by professionals in the trade for more than 30 years.
- Solution with A1 approval essential to pass CSTB approvals
- Fire and gas barrier
- Compressible rope lagging, available from 12 to 120 mm diameter
- For diam >120 mm possibility of so-called "earthquake-resistant" fire-resistant mat
- Excellent thermal (750°C) and mechanical resistance
