In high-volume injection moulding, every second counts. Reducing cycle time while maintaining precision can make the difference between meeting production goals and falling behind. Top entry robots are one of the most effective solutions to achieve this balance—offering speed, accuracy, and reliable part handling for a wide range of moulding applications.

What Are Top Entry Robots?

A top entry robot is an automation system mounted above an injection moulding machine (IMM). It moves vertically into the mould area from above to remove finished parts quickly and efficiently, often in just fractions of a second.

They are widely used in industries where fast cycles, large volumes, and consistent part quality are essential.

How Top Entry Robots Work

1. Robot waits above the IMM during mould closure and injection.

2. Mould opens and the robot arm moves down into the cavity.

3. Grippers or suction cups remove the part(s) with precision.

4. The robot lifts the parts out and places them on a conveyor, cooling station, or packaging system.

This vertical movement allows top entry robots to minimize travel distance, which means faster cycles.

Benefits of Top Entry Robots

✅ High-Speed Operation

Designed for rapid up-and-down motion, reducing idle time between moulding cycles.

✅ Improved Product Quality

Parts are handled consistently, reducing deformation, scratches, or contamination.

✅ Increased Productivity

Runs 24/7 without fatigue, meeting high-demand production schedules.

✅ Better Safety

Keeps operators away from moving platens and high-temperature moulds.

✅ Integration Flexibility

Easily integrates with in-mould labelling (IML), part stacking, or automated packaging lines.

Applications of Top Entry Robots

• Food Packaging – Thin-wall containers, lids, and cups

• Automotive – Interior panels, trims, and small components

• Medical Devices – Sterile plastic parts

• Consumer Products – Toys, appliance components, electronics housings
