Our products

Product category: Raw material for glass production

TUBE PRODUCTION

In 2013 JSJ took over the tube machinery division of IGM. Based on practical experiences JSJ engineers improved the IGM machines in order to offer machines, which excels the state-of-the-art. The advantages of the tube production with JSJ’s machinery are not only the production of highest glass quality and dimension stability, but also a production with a high yield, which benefits our customers. 

JSJ offers machines for the Danner-, Vello- and Draw-Down-process, e.g.:

Danner machine
Height adjustable runway
Drawing machine
Rough cutting and sorting unit
Fine cutting and glazing machine
Shrink wrapping plant
Additionally JSJ offers the required measuring devices for dimension and quality inspection for control and sorting.

GLASS MELTING

The expertise of JSJ’s engineers is to provide our customers with glass melting plant to produce economical and environmentally friendly high quality glass. The production of high quality glass requires not only the best technology for the melting, but also advanced glass conditioning systems. For both we use reliable systems and components.

HEAT TREATMENT

In 2009 JSJ Jodeit took over the glass division of the French company EFR (former CFR). Based on decades of practical experience out of a countless number of reference plans, JSJ today is able to supply its customers with state-of-the-art glass treatment equipment and special machinery.
BELT TEMPERING
The resistance of plates, dishes, bowls, fridge-ware, washing machine glasses and car lamp covers against mechanical damages and temperature shocks can be increased by tempering on belt. First the glass articles are heated up in a tunnel oven to a defined temperature. Then by high speed convection of cold air flow the external glass surface is cooled down very fast, causing compression stresses on the outside of the glass which lead to a significant raise in mechanical stability and resistance against thermal shocks.

 
SPINDLE TEMPERING
The decision to choose a spindle tempering process is mainly made by reason of the shape and dimensions of the articles to be treated. Articles with low stability and deep dimension like: stemware coffee and tea cups, tumblers, and similar have to be tempered on spindles to get a full tempered article with high quality.

 

JSJ can offer spindles tempering and decorating lines with speeds capacity up to 100 pcs/min.
ANNEALING AND DECORATING
JSJ lehrs are special designed taking in consideration environmental aspects, working at very low energy consumption and nearly maintenance free.

About us

Company details

The core competence of JSJ lies in the development, planning and erection of tailor-made melting furnaces for specific glass compositions. The deep scientific – technological orientation of JSJ covers also the relevant glass specific aspects as well as those of production technologies.

In particular JSJ turns its attention on providing complete plant to its customers. E.g. JSJ engineers have the capability to provide the complete production plant and technological know-how for glass melting and tube forming from one source.

A second important field of activity is the glass heat treatment equipment and the special machinery. Based on decades of practical experience out of a countless number of reference plant, JSJ today is able to supply its customers e.g. with state-of-the-art belt, spindle type or rim tempering lines and machines, special casting machines or complete plant for chemical strengthening of glass.

In the latter case JSJ experts can look back on more than 15 years of practical chemical strengthening experience. Today, JSJ develops and supplies highly automated solutions including required process know-how for all areas of application.
