Runnerless LSR molding.


What hot runners are to thermoplastics, cold runners are to thermosets thermosets, materials that can not be softened on heating. In thermosetting polymers, the polymer chains are joined (or cross-linked) by intermolecular bonding. Thermosets are usually supplied as partially polymerized or as monomer-polymer mixtures. Cross-linking is achieved during fabrication using chemicals, heat, or radiation; this process is called curing or vulcanization. like liquid silicone rubber (LSR LSR - Label Switch(ing) Router (MPLS)

). Two cold-runner systems for LSR were introduced at this year's NPE show in Chicago.

ALBA Enterprises Inc., Rancho Cucamonga, Calif., showed the CRS cold-runner system for thermoset LSR and EPDM elastomers. The standard system features the Quattro pneumatic shutoff nozzles and chokes, a valve-gate system that imparts minimum mechanical shear and with-stands high curing temperatures without crosslinking resin in the gate area.
