Glass Laminating Autoclave

Autoclaves for the production of Laminated Safety Glass

Glass is a fascinating material. However, only when it is safe it is universally usable without any risk of danger. XIRTUE develops complete autoclave systems for the production of laminated safety glass.

Every single autoclave made by XIRTUE for the production of laminated safety glass is a custom product. Hence, we take the greatest effort to fulfil all our customer’s requirements right down to the slightest detail. This also applies to services and performances, which are not explicitly listed in our delivery program. Talk to us! We will take care of your requests.

Autoclaves: Complete autoclave systems with pressure and temperature control for the production of laminated safety glass as well as windscreens for the entire product range.

Temperature homogeneity: Guaranteed temperature homogeneity throughout the entire working area via optimised ventilator and optimised airflow and through the special alignment of the heaters. Process optimisation based on an analytic computer simulation of the airflow characteristic and temperature distribution

Components: Air receivers, valves and fittings, compressors, cooling tower stations Fabrication: Construction and fabrication according to CE (PED), ASME, GB all International regulations

Quality Control System: Application of the most modern production facilities. All necessary tests can be carried out on-site. This guaranties high quality, proven product characteristics at the highest level of safety.

Technical Data: Usable length and any other operating parameters produced as requested or according to customer specification.

  • Maintenance-free air circulation system
  • Process safety system for batch protection in the case of a power cut

Laminated Glass: Laminated glass is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by an interlayer, typically of polyvinyl butyral (PVB), between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces. This produces a characteristic “spider web” cracking pattern when the impact is not enough to completely pierce the glass.

Laminated glass is normally used Skylight glazing and automobile windshields typically use laminated glass. Laminated glass is often used in exterior storefronts, curtain walls, and windows. The PVB interlayer also gives the glass a much higher sound insulation rating, due to the damping effect, and also blocks 99% of incoming UV light.

Architectural Laminated GlassIn the manufacturing process, the assembly of float glass and PVB are laminated together and then placed in an autoclave. A typical autoclave lamination cycle ramps pressure to 180 psi (12.4 bar) and temperature to 280 °F (137 °C). The cycle completes after 30-60 minutes. Cooling is ramped down at a controlled rate in order to reduce thermal stress and cracking. Vacuum bagging of parts is also used to help remove bubbles and improve overall part quality.
