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) LSR - Laboratory for Space Research LSR - Laboratory of Sensorimotor Research LSR - Land Speed Record LSR - Landscape Suitability Ranking LSR - Large Ship Reactor LSR - Laser LSR - Laser Spot Receiver LSR - Late-Successional Reserves (forestry) LSR - Launch Signal Responder LSR - Launch Site Recovery LSR - Launch Support Requirement LSR - Launch Support Room LSR - Leadership Strength Readiness). 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.

With the decline of the regional auto industry, the city has become a technology center for companies from a number of industries., Mich., offers a standardized cold-runner system for LSR or other thermoset rubbers. Its KKS KKS - Kesselprüf und Korrosionsschutz GmbH KKS - Kinsella Khemical Sales (Ireland) KKS - Kraftwerks-Kennzeichen-System KKS - Kretskort Service (Norwegian electronic design firm) system has pneumatic needle shutoff and restrictors that minimize leftover sprue volume. A standard system can have two to 16 drops with seven nozzle styles. Tel: (248) 544-5718 * PT Direct: 257FB [ILLUSTRATION OMITTED] |
