Plentiful ingenuity is observed in production,
material selection, and designing processes.
We show several technologies through an opening trim weatherstrip
here. All technologies explained here, including those developed for
the first time in the world, are in the top level, and use sophisticated
know-how.
Extrusion molding is a fundamental production technology. In particular,
variable extrusion molding, the first of its kind in the world, can
change a length of a rip in a trim in accordance with the thickness
of a body to which a weatherstrip is assembled. Automatic three-stage
control of a rip in a trim at an extrusion opening has materialized
variable extrusion. As a worker used to cut it when it is too thick,
this technology has increased productivity, and contributed to reduced
waste due to fewer cuttings.

 In
the area of material engineering, TG is trying to make a product lighter.
An opening trim material reduces a product mass while maintaining
the same strength as before with a minute foam dense rubber, which
is the first in the world as well. |

Plenty of technological know-how to respond to various
needs
Decorating technologies have been actively developed to meet the needs
of product design. One of them is fabric touch processing, which covers
a base material with foamed surface thermoplastic polyolefin, TPO
(the first in the world). This has been already introduced to production,
and contributed to improving texture.
Examining a W/S cross-sectional surface has overcome any appearance
problem. As a wrinkle tends to occur on the hollow part of a curved
line in a corner when integrally extruding a material, the die-formed
part used to be attached to the part. A cross-sectional design was
changed in a new model of Harrier to see no wrinkle even without a
die-formed part. Since the new weatherstrip is produced through integral
extrusion molding, there are no connected part and color and luster
differences, which were seen in the corner, improving the product
appearance as a whole. |
