3-Axis Servo Robots for Injection Molding
KEFAN 3-axis servo robots for injection molding provide stable part take-out, sprue separation and placement for standard molding cells. Send your machine tonnage, part weight and target cycle for a configuration and quotation.
Updated design, consistent servo control
The updated blue-series platform uses independently controlled X, Y and Z servo axes for smooth motion from mold entry to release, helping maintain a consistent production rhythm.
Stable Motion
Servo-driven traverse, vertical and kick motions deliver controlled acceleration and repeatable positioning.
Shorter Take-out Time
Optimized motion paths support efficient mold entry, part removal and placement.
Flexible Programming
Recipes can be adjusted for different molds, products, release positions and downstream sequences.
Easy Integration
Connect the robot with injection molding machines, conveyors, safety devices and auxiliary equipment.
Configured to fit your machine and part
The right robot depends on more than molding machine tonnage. Our team checks the real working envelope, finished-part weight, EOAT weight, take-out direction and required cycle before recommending a model.
- Machine: molding machine tonnage, tie-bar spacing and platen height
- Part: dimensions, weight, material and removal direction
- Motion: traverse, vertical and kick stroke requirements
- Process: target cycle, release position and downstream operation
- Tooling: gripper layout, sensors, vacuum circuits and sprue handling
Configuration Overview
Verified 3-axis servo robot configurations
The following S3 models and core selection data are taken from the KEFAN Robot Catalog dated October 31, 2023. Final configuration is confirmed against the current machine, mold, EOAT and required cycle.

| KAI800S3 | 90-200T | 1300 mm | 620 mm | 800 mm | 5 kg |
| KAW850S3 | 120-260T | 1450 mm | 720 mm | 850 mm | 6 kg |
| KAW950S3 | 180-300T | 1450 mm | 820 mm | 950 mm | 5 kg |
| KAW1100S3 | 260-400T | 1750 mm | 820 mm | 1100 mm | 7 kg |
Catalog reference data. Specifications and availability should be reconfirmed for each quotation.
One platform, multiple production tasks
Suitable for repeatable automation around injection molding cells, from simple take-out to coordinated post-mold handling.
Part Take-out
Remove molded parts quickly and consistently while reducing manual access to the mold area.
Sprue Separation
Separate parts and runners through planned release positions or compatible downstream equipment.
Conveyor Placement
Place parts onto conveyors in a stable orientation for collection, inspection or the next process.
Insert Loading
Load inserts with a purpose-built gripper when product geometry and process conditions allow.
Stacking & Sorting
Arrange finished parts by count, orientation or production batch for easier downstream handling.
Cell Automation
Coordinate with fixtures, inspection, labeling and packaging equipment in a tailored system.
From application review to production
A practical engineering process keeps robot selection, tooling and site integration aligned with your actual molding requirements.
Share Requirements
Send machine details, mold and part information, photos or drawings, and target cycle time.
Confirm Configuration
We review robot reach, payload, EOAT, signal interface and downstream handling needs.
Build & Test
The selected robot and tooling are prepared and the working sequence is checked before delivery.
Install & Support
We provide operating guidance and technical support for commissioning and production use.
Automation built around the application
A robot performs well only when the machine interface, gripper and motion sequence work together. Kefan supports the complete application rather than treating the robot as a stand-alone component.
- Robot model selection based on the actual working envelope
- Custom EOAT for product geometry and handling requirements
- Integration support for conveyors and auxiliary equipment
- Clear communication from evaluation through production
Frequently Asked Questions
What information is needed for robot selection?
Please send the molding machine brand and tonnage, tie-bar spacing, part dimensions and weight, mold photos or drawings, required release position and target cycle time.
Can you supply a custom gripper?
Yes. EOAT can be designed for vacuum pickup, gripping, inserts, runners and part detection according to the product and process.
Can the robot connect to my injection molding machine?
Signal integration is reviewed during project confirmation. Share the machine brand, model and interface information so compatibility can be checked.
Can it work with conveyors or other equipment?
Yes. Conveyors, fixtures, inspection, stacking and other peripheral equipment can be included in a coordinated automation solution.
How do I get an accurate quotation?
Send the project details listed above. We will recommend the suitable configuration and quote according to the robot, EOAT and integration scope.
Need the right 3-axis robot for your molding cell?
Share your machine tonnage, part weight and target cycle. Our team will recommend a practical configuration.
