Product Description
ALBA Silicone Cold Runner Systems
The following features permit the economic manufacture of silicone injection molded articles of high quality both technically and optically:

1. 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.

2. Shorter set up times thanks to rapid clamping elements for simple, fast fitting of the contour units to the CRS.

3. Fabrication of molded articles with reduced sprue is achieved by precisely defined thermal separation between the cooled CRS and heated contour unit.

4. Reduced injection point marking thanks to needle valve controlled feed system ensuring optimum quality of the molded articles.

5. 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.

6. 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.

7. Optimum balancing of the multiple CRS by regulation of the mass flow per cavity integral choke units.

8. Minimum mechanical load on the liquid silicon rubber thanks to large cross sectional areas of the feed zones
