The Flexible Holder (-S3 spec.) is a direct-mount ejector specifically designed for use with vacuum pad holders in secondary battery manufacturing processes. It enables efficient and reliable transfer of workpieces by creating a vacuum using compressed air, ensuring precise positioning and secure handling during automated operations.
The main resin components are made from PBT (polybutylene terephthalate), a standard engineering plastic well-suited for general industrial environments. Metal parts are constructed from brass with electroless nickel plating, providing durability and corrosion resistance. The seal rubber is composed of NBR (nitrile butadiene rubber), which serves as an effective sealing material though it has limited ozone resistance.
The ejector features a direct-mount design that connects securely to the vacuum pad holder. It is engineered to interface with various thread types including metric male threads (M5x0.8, M6x1), taper male threads (R1/8, R1/4, R3/8), and NPT male threads (NPT1/8, NPT1/4, NPT3/8), allowing for compatibility with a range of existing vacuum pad systems.
The holder operates using air as the fluid medium. It is rated to function within an operating pressure range of 0.15 to 0.7 MPa, with a specified rated supply pressure of 0.5 MPa (H, L type) or 0.35 MPa (E type). The system can operate effectively across temperatures from 0°C to 60°C, with no freezing allowed.
Available in multiple metric sizes including φ3, φ4, φ6, φ8, φ10 and φ8, φ12, as well as inch sizes of φ1/4", φ5/16", and φ3/8". The -S3 specification ensures compatibility with secondary battery manufacturing workflows where precise workpiece handling is required.
The flexible holder integrates directly into vacuum pad holders via threaded connections, supporting standard metric, taper, and NPT thread interfaces. This direct mounting eliminates the need for additional adapters or complex alignment mechanisms, simplifying installation and ensuring secure, stable operation within automated battery production lines.
