Servo-Driven Robots for Injection Molding Automation

A servo-driven take-out robot uses servo-controlled linear axes to enter the injection mold area after it opens, extract the molded part using EOAT, clear the mold before it closes, and traverse to the downstream release or placement position. The motion sequence is programmed and can be adjusted through the robot controller.

No. Yushin America provides injection molding take-out robots and automation systems that use servo motion internally. Yushin does not sell standalone servo motors, servo drives, or robot components as separate products.

A servo-driven robot uses servo motors to control its main linear motion axes — the vertical, kick, and traverse movements that make up the take-out path. An NC servo wrist is an optional orientation attachment that adds one or more controlled rotational axes to a suitable robot configuration. The two serve different functions: the robot axes move the arm through the extraction path, while the wrist provides controlled orientation of the EOAT or part.

Servo-driven axes allow the controller to program position, speed, acceleration, and motion profiles for the specific mold, part, and cycle requirements. This provides a repeatable extraction path, adjustable motion tuning, and the ability to store and recall programs for different molds. Yushin has applied servo drive to its take-out robots as part of the development of its injection molding automation platform.

An NC servo wrist is appropriate when the application requires controlled rotational movement between the part pickup and placement positions. This includes insert loading where the insert orientation must change, overmolding with angled placement, angled downstream release, or multi-position inspection. A servo wrist is not required for standard take-out where the extraction and placement paths do not require rotation.

Yes. Insert loading, overmolding, and complex part orientation are Yushin-supported applications. These are handled through engineered EOAT, insert-handling tooling, and NC servo wrist configurations as required. These are advanced application capabilities, not limitations of the servo-driven take-out robot architecture.

Robot selection starts with the application: the injection molding machine, mold layout, part geometry and weight, EOAT requirements, required stroke on each axis, take-out time, downstream placement, and any orientation requirements.
