Choose a tool by the decision in front of you
Machine sizing
Start with projected area, clamp tonnage, shot size, and shot volume when screening a press or injection unit.
Process planning
Use cooling and cycle time before estimating hourly output or a cavity requirement.
Material and cost
Connect finished-part mass to material use, resin cost, scrap, and tooling allocation.
Production follow-up
Use parts per hour and utilization to separate a theoretical cycle from an achievable schedule.
Each tool is a first-pass estimate. Follow the linked guide when a decision depends on pressure, cooling, material grade, or machine data.
