You build your own moulds and are looking for a fully developed save and economic cold runner system ? Our cold runner systems with needle valve gating technology enable a troublefree , material- saving and material-friendly production of LSR-mouldings. We build these systems as a standard or tailor made to your requirements or application using our more than 40 years of experience in this field. The systems can be adapted and adjusted to various moulds in order to be flexible and cost saving. We build needle valve cold runner systems with 1 to 32 nozzles (depending on application). The needle drive system can be hydraulik (standard), pneumatic or electronic. Your advantages when using our cold runner systems: - wasteless part production (no material loss for a cured hot runner) - no rework on parts necesarry (removal of runners etc.) - better part quality due to a material frienldy processing (low shear, no pre- curing) - thermal stability even when processing fast curing material due to an eccelently adjusted cooling - easy handling, cleaning - low and easy maintanace - simple replacement or exchange of parts like nozzle tip, nozzle, closing needle, seals etc - realize different nozzle plung in depth (cold runner nozzle into the mould) by exchanging nozzles - due to exchangable nozzle tips / needles you can realize different injection hole diameters using one system. - due to the ability of nozzles beeing exchanged against plugs you can us a 16 nozzle cold runner system to feed moulds with only 2, 4 or 8 cavities.

Needle valve cold runner systems for Liquid Injection Moulding (LIM) of LSR ( Liquid Silicone Rubber)

Moulding technology for Liquid Silicone rubber (LSR)

8 nozzle cold runner - 4+4 horizontal

8 nozzle cold runner - 4 horizontal

cold runner for intergation in 2C mould 4 +4 nozzles

12 nozzle cold runner - 6+6 vertikal

Exchangable nozzle tips make our cold runner systems very flexible in use and applicationl concerning the injection hole diameter.

Exchangable nozzles in 4 (act.5) different length make our cold runner systems very flexible in use and applicationl concerning the plung-in depth (nozzle into mould).

Below you will find just a few examples of LSR cold runner systems that we have build for customers worldwide.

Flow- trough amount for each nozzle can be set by a valve (in standard system - hydraulik needle drive). In electrical or pneumatik driven systems by needle way or opening- time.
