Product category: Furnaces for chemical pre-tempering of glass

Glass / Ovens Thermal Tempering

LEMA units, designed in 1970 to temper solar lenses without any optical distortion, are perfectly customable for smallest glasses temper (made for many different applications: watches glasses, sub masks, protection screens, industrial and scientific glasses etc. ); our ovens temper glasses with a minimum thickness of 1,3mm. and they are the only ones on the trade.

This is an example of how it is possible to obtain, from a good starting project, the highest temper quality, even in critical conditions, without any mass-production loss. Microprocessor control units control precisely the tempering.

The ovens are built with high mechanical and electrical toughness materials which grant the long lasting of the machine, even if continuously operating. Our first units are still operative after 35 years.

Glass / Ovens Chemical Tempering

LEMA, leader in the manufacturing of ovens for glass chemical tempering, is the only factory in the world that may boast more than 35 years experience, experience that allowed us the development of optimized equipment for any applications.

Our production of such equipment, started in 1972 with the first ovens for the chemical tempering of optical and sunglass lenses, up to now, with equipment for tempering big glasses like the last realized model for processing glasses 3200x2200mm max dimensions.

Glass / Polariscope

The polariscope is an analysis device built to detect residual tensions over transparent glass articles. Glass analysis is made inserting the sample between two polarizing filters and then observing the light changes of intensity and colour transmitted through the instrument, it is possible to perceive the glass status. Polariscopes must have the following features:
- White light source irradiated by incandescent lamp
- Polarized field composed by two crossed polarizing filters

About us

Company details

LEMA is a society that started in 1971, initially projecting and building machines and devices for solar and ophthalmic lenses treating, production, controlling and processing.

In 1972, at the same time an American law obliged to produce anti-collision lenses, LEMA decided to apply the glass chemical temper treatment, process previously used just for aerospace glasses, to its ovens production.

From 1971 until now our production always stay focused on machines and devices for the optical sector, with a special attention to chemical temper ovens made for big glasses industrial sector production.
