Injection Molding Robot Selection Guide for First-Time Buyers: 7 Specs to Check
TL;DR — The 7 specs that decide whether the robot fits Spec 1 — Payload: the robot must carry the part weight plus the runner weight, with a 1.5 to 2.0 safety margin. Underspecifying is the most common first-time buyer mistake. Spec 2 — Stroke: vertical and horizontal reach from the mold open ...Read more -
How to Choose Injection Molding Machine Tonnage: A 6-Step Formula With Examples
Quick Answer (For Molding Engineers & Factory Procurement) Tonnage sizing starts with F ≥ P × A × safety factor (typically 1.2-1.5) — projection area × cavity pressure × safety. For a typical PP thin-wall container at 38g shot weight and 320 cm² projected area, 50-90 ton clamp force is suff...Read more -

Robot Arm Take-Out Time vs Total Cost: Why Cycle Time Alone Does Not Determine ROI
The Speed Trap in Robot Arm Selection When I sit down with injection molding factory owners to discuss robot arm specifications, the conversation almost always starts with take-out time. “How fast can your robot take the part out of the mold?” It is a fair question, but it is also th...Read more -
Granulator Sizing Guide for Factories Running 6+ IMMs With Recycled PP and ABS
Why Granulator Sizing Matters More Than You Think When I visit injection molding factories that run six or more injection molding machines (IMMs), the granulator is often the bottleneck nobody notices until it is too late. I remember visiting an injection molding factory in central Turkey that w...Read more -
Mold Temperature Controller for Medical Polycarbonate Injection Molding
Key Takeaways Medical polycarbonate requires mold surface temperatures of 80°C–120°C with ±0.5°C controller accuracy to prevent birefringence and dimensional drift. Auto-tuning PID algorithms eliminate manual parameter adjustment and deliver repeatable results across mold changeovers. Independe...Read more -
