KOR-LOK Side Action Systems
Our patented KOR-LOK systems provide 10x greater force than standard cylinders for core pull applications. These hydraulic locking systems maintain 100% preload at zero pressure to eliminate flash in injection molding and die casting. The internal wedge mechanism ensures zero movement during injection for perfect part quality.
Quick Mold Change Systems
Hydra-Jaws systems enable rapid mold changes with hydraulic clamping force and mechanical locks. These systems reduce changeover time by up to 70% while maintaining precise alignment. The slot design allows flexible clamping configurations for various mold sizes in single machines.
Quick Die Change Systems
Our QDC systems offer customizable die change solutions with hydraulic clamps and mechanical lifters. These systems implement SMED principles to reduce die change time while maintaining safety. Components include high-force clamps, bolster extensions, and 5,000 psi hydraulic controllers.
Self-Locking Cylinders
Self-locking cylinders maintain position without hydraulic pressure using mechanical locking segments. These actuators hold loads up to 10x greater than standard cylinders. Available in both lock-on-extend and lock-on-retract configurations for industrial automation applications.
Modular End-of-Arm Tools
Our EOAT solutions feature high-force grippers with compliance devices for robotic automation. These modular systems include crash protection and metal-backed gripper pads. Designed for both heavy industrial and collaborative robot applications with fused metal construction.
Questions
What makes KOR-LOK different from standard locking cylinders?
KOR-LOK provides 10x greater force than standard cylinders through its internal wedge mechanism. Unlike reactive systems, it applies proactive preload force that maintains position during injection, eliminating flash and ensuring perfect part quality.
How do Quick Mold Change systems improve efficiency?
Hydra-Jaws systems reduce mold change time by up to 70% using hydraulic clamping with mechanical locks. The slot design allows flexible clamping configurations while maintaining precise alignment for various mold sizes in single machines.
Can self-locking cylinders hold loads without hydraulic pressure?
Yes, our self-locking cylinders use mechanical locking segments to maintain position without hydraulic pressure. They can hold loads up to 10x greater than standard cylinders in both lock-on-extend and lock-on-retract configurations.
What support do you offer for system integration?
We provide free application reviews with CAD modeling, force calculations, and on-site technical assistance. Our engineers help with system selection, installation, and optimization for specific manufacturing requirements.
How do SWITCHMAX connectivity solutions work?
SWITCHMAX integrates multiple sensors into single machine inputs with LED indication. It cross-checks sensor positions for safety and provides plug-and-play wiring for KOR-LOK systems and other mold sensors.
What industries benefit most from your solutions?
Our systems serve injection molding, die casting, metal stamping, and robotic automation industries. Manufacturers use our technology to improve part quality, reduce downtime, and increase production efficiency across various sectors.
