Building on over thirty years of experience, developed
in the field of manufacturers of electric
furnaces for glass manufacturing and processing,
SIM S.r.l. nowadays develops and manufactures
all kinds of spare parts for the aforementioned
In our company we test always innovative electric
heating systems and solutions related to
thermal insulation and/or handling of the glass
itself. Among the countless items, we produce:
• electric resistances of all kinds, useful for
glass melting and/or quenching and bending;
• insulating fabrics and ceramic release agents;
• seals and systems for temperature measure
ment and control;
• roller passages in dense and/or insulating
• articles of various kinds and composition ac
cording to the customer’s specific request.
STRAPS, SOCKS, BRAIDS AND GLASS FABRICS
Our products in this family are made entirely
of glass fiber 6-9 μ. They melt only at very high
The strap is an extremely flexible and soft gasket.
Also available is the “twisted-strap”,
twisted with an external “shoe” to improve the
compactness when cut.
They are used in the manufacturing of joints for
furnaces and in the thermal insulation of electric
wires. The “socks” are used in the thermal insulation of pipes, while the braids are used
as watertight seals.
We also offer glass ribbons and fabrics, different on from the other for the weft and the type of
raw material used, useful in the glass production and processing.
AISI socks are made by braiding strands of AISI 316 L stainless steel, so as to make them more
resistant to high temperatures and to prevent thermal shocks and micro-cracks in the manufacturing
of glass products.
Glass industry: coating of grasping and handling equipment; guidance of the products on automatic
production lines of hollow glass industry.
AISI KNITTED SOCKS
The AISI knitted socks are made by tubular knitting of AISI 316 L stainless steel wires, so as to
make them more elastic and then get the ideal solution for coating.
They can also be processed by weaving steel wires with aramid fiber, thus increasing costcontainment.
The combination steel – aramid ensures that the sock takes on a yellow-green color.
The AISI 316 stainless steel makes the sock particularly resistant to high temperature
and allows to prevent thermal shocks in the processing of glass products.
Coating of transport rollers in the flat glass industry (for this specific use, the socks prevent the
glass from coming into contact with the rollers).
Coating of hoses used at high temperatures. Expansion joints.
The AISI tapes are made by weaving one or more layers of AISI 316L stainless steel. They can
also be knitted (net AISI tapes), knitted by weaving of stainless steel wires and PBO yarns (AISI
tapes + net PBO) and processed by weaving of stainless steel wires with aramid fiber.
Coating of thrusters in the hollow glass industry.
Resisting to very high temperatures, they prevent thermal shocks and micro-tears which can be
fatal during the bottling process.
The production methods makes the product particularly resistant to abrasion.
These stainless steel tapes can also be used, when folded, for the guidance of the articles on
automated production lines.
