ANAHEIM, CALIF. — Mold maker Caco Pacific Corp. of Covina, Calif., has developed improvements that allow the use of direct hot-runner gating techniques for parts such as pipette tips.
``These improvements allow us to use direct gating techniques for parts that previously had been made with conventional cold runners,'' said Michael Barishman, account manager.
The techniques meet proprietary customer needs.
Also, Caco Pacific developed hot-runner systems for tubular parts and medical cuvettes that have used direct valve-gating technology for molds with as many as 64 cavities.
Other molds using hot-runner technology include flasks and medical caps. Cavitations range up to 96 cavities in both single-face and stack-mold configurations.
