Suzhou Handrin Robot Technology Co., Ltd., with the brand name GS Eoat, on showed standard grippers and other spare parts for robotic arms EOAT assembly at Chinaplas 2025 with 6 axis servo industrial robot.

The robotic arm EOAT is a tooling to pick the parts from the injection molding machine or other stations in an automation system according to the structure and shape of the parts to finish the production process atuomatically. It would be assembled from a variety of different parts like buffer fitting, function executive element etc. The GS standard grippers will help to projector to assemble the EOAT easily like play a LEGO building block. A regular sets of EOAT will include:

• Function Executive Element
• Buffer Fitting
• Fast Switching
• Accessories
• Pneumatic Finger Pick
• Air Nippers
• Sprue Gripper
• Vacuum Cups
• Fixture Modular Assembly

to finish the production process like parts picking, plastic parts sprue cutting, polishing, welding etc.

With the GS standard modular EOAT parts, the engineer who is designing a tooling for an injection automation system will be able to formulate an EOAT design for his project quick and easy for installation.

PVC pipe fittings are one of the most commonly used connector in the drainage project and a cold runner designed mold is the most economic solutions for the production of the PVC pipe fittings, but the removal of the runner in result is a labour intensive work. Is there any economic way to remove the runners from the PVC pipe fittings automatically?

For the producer of PVC pipe fittings the most economic soluton to remove the runner is with an Air Nipper fixed to the picking robot immediately after the PVC pipe fittings picked out from the mould. The robot will drop the seperated pipe fittings and runner to different containers. Below configuration of SWITEK runner cutting solution for 16 cavities PVC pipe fittings for your reference:

• Injection Molding Machine: HaiTian MA4500
• Picking Robot: SWITEK SW6712S 3 Axis Servo Injection Robot
• Mold Design: 16 Cavities
• Air Nipper: 4pcs
• Cycle Time: 60s

The Air Nipper runner cutting system is an easy to start solution for the producers of PVC pipe fittings, which the Air Nipper would be controlled by the picking robot and is the best solution for the small size PVC pipe fittings (with a diameter around φ25mm). Anyway it also must be custom made according to the mold design.
