The following features permit the economic manufacture of
silicone injection molded articles of high quality both
technically and optically:
- The CRS is supplied completely set-up. Standard and special
gauges(nozzle spacings permit the individual usage of a CRS
for several contour units even with different molded
articles.
- Shorter set up times thanks to rapid clamping elements for
simple, fast fitting of the contour units to the CRS.
- Fabrication of molded articles with reduced sprue is
achieved by precisely defined thermal separation between the
cooled CRS and heated contour unit.
- Reduced injection point marking thanks to needle valve
controlled feed system ensuring optimum quality of the
molded articles.
- Closing of the fee orifice by means of the needle valve
system prevents cross linking of the LSR (Liquid Silicon
Rubber) in the sprue bush when the unit contour is at high
temperature.
- Shorter cycle times thanks to the possibility of high
temperatures of the contour unit and therefore variable
vulcanization times for standard molded articles and
particularly in the case of relatively large mould ed
articles.
- Optimum balancing of the multiple CRS by regulation of the
mass flow per cavity integral choke units.
- Minimum mechanical load on the liquid silicon rubber thanks
to large cross sectional areas of the feed zones.
The single nozzle CRS is financially advantageous
alternative to the multi nozzle CRS for the creation of
models, prototypes and small runs.
