Semi-circular hole punching machine is a specialized punching die installed on a fully automatic bag-making machine. It is suitable for flexible packaging materials such as PE, PP, OPP, and composite films. It utilizes a Japanese wire EDM machine with a rounded cutting edge, an imported high-speed steel punch, and an Airtac cylinder. The resulting notch is smooth, burr-free, and precisely aligned, ensuring smooth tearing without deviation. The notch size, depth, direction, and installation method can all be customized.
