ＳＩＭＴＥＸ FILAMENT
What is ＳＩＭＴＥＸ FILAMENT?
SIMTEX is the extended polyolefin-based fiber which is fully recyclable.
SIMTEX filament consists of core and specially formulated shell on the core surface.
The conjugate multi-filaments are processed to lead filament yarns whose highlyoriented cores have high strength and high modulus, and shell become together.
It is used as a reinforcing structure of a self-reinforced composite.

Molding method
1) Hot-pressing method in which heating and cooling are continued withthe same mold without transferring materials◆It uses a hot-pressing machine that attached the adjustable die.
◆After setting the material in a mold, by heating / cooling a die, it isintegrated and formed. (Setting of rapid heating / cooling system is desirable)

2) Pre-heating and cold-pressing method by transferring pre-heatedfabric to a cold mold for pressing(Stampable sheet molding method)◆After heating the material by heating arrangement, the material istransferred to the cooling press and molded.
◆Molding is possible in a short time than hot-pressing method.

Molding condition (example)
Cutting &Stacking

Several cut fabrics
are laminated sothat the desired
thickness of themold goods can beachieved.
If 1mm thickness
is necessary, 3-4
ply fabrics with
250g/m2 per one
ply will be used.

HeatingPress ＆ Cooling

By heating arrangement,
the laminated fabric isheated enough until thetemperature inside of thematerial reaches totargeted one.
(ex. SFE: 120-140℃)The heated material istransferred to the mold,and pressed.

In case two molds areavailable, one is applied forheating, another for cooling.

Completion !

Pressure: 0.5-3MPa(it varies according toshape of products)
It is desirable to control
the temperature by watercooling systems.
