In injection molding, cycle time is the heartbeat of profitability. Every second trimmed from the mold’s open‑close‑cool sequence compounds into major gains: lower part cost, higher throughput, and more predictable delivery schedules. At Pacific Plastic Technology, we treat tooling design as an engineering discipline, not a commodity. The decisions made long before steel is cut, including runner strategy, cooling layout, steel selection, and maintenance planning, directly determine how efficiently a mold will run for years to come. This is a look inside PPT’s tooling playbook and the design choices that consistently reduce cycle time while protecting long‑term ROI. Hot vs. […]
