In the production process of leather products, punching is a crucial process. It not only affects the aesthetics of the product, but also directly affects the breathability and comfort of the product. The key equipment to complete this process is the leather perforating machine. This article will explore the working principle, type, operation process and importance of the leather perforating machine in the leather processing industry, and take you to unveil the mystery of this efficient and precise processing equipment.
1. Working principle of leather perforating machine
In short, the working principle of the leather perforating machine is to form regular holes on the leather by mechanical or laser means. This process seems simple, but it actually contains complex technology and processes. According to the different punching methods, leather perforating machines can be roughly divided into two categories: mechanical perforating machines and laser perforating machines.
Working principle of mechanical perforating machine
The mechanical perforating machine mainly uses a crank slider mechanism or a hydraulic transmission system to punch the leather through a mold to form the required holes. Specifically, when the machine starts, the motor or hydraulic cylinder provides power to drive the crank slider mechanism or the hydraulic cylinder piston to move. The crank slider mechanism converts rotational motion into linear motion, driving the punch (i.e., mold) up and down. When the punch contacts the leather, the huge impact force causes the leather material to undergo plastic deformation under the action of the mold, thereby forming a hole.
The key components of a mechanical perforating machine include a punch, a mold, a crank slider mechanism (or a hydraulic cylinder), a transmission system, and a control system. Among them, the material, shape, and size of the punch and mold directly affect the quality and effect of the punching. High-quality materials and precise dimensions can ensure the flatness and accuracy of the punching, and reduce burrs and tearing.
Working principle of a laser perforating machine
Unlike a mechanical perforating machine, a laser perforating machine uses a high-energy laser beam to instantly heat and vaporize the leather to form holes. The working principle of a laser perforating machine is based on the principle of interaction between laser and matter. When the laser beam is irradiated on the surface of the leather, the laser energy is absorbed by the leather material and converted into heat energy. As the temperature rises, the leather material begins to melt, vaporize, and even burn, forming holes.
The key components of a laser perforating machine include a laser, an optical system, a control system, and a workbench. The laser generates a high-energy laser beam, and the optical system is responsible for focusing the laser beam onto a very small spot to improve processing accuracy and efficiency. The control system is responsible for controlling the laser’s output power, scanning speed, processing path and other parameters to achieve precise punching processing.
2. Types of leather perforating machines
Leather perforating machines can be divided into many types according to different processing methods, degree of automation and scope of application. Here are some common types of leather perforating machines:
Manual leather perforating machine:
This type of punching machine usually requires the operator to manually operate the punch to punch. It has a simple structure and low cost, but its punching efficiency and accuracy are relatively low.
Semi-automatic leather perforating machine:
Semi-automatic leather perforating machine combines the advantages of manual and automatic operation. It can automatically complete part of the punching process through preset programs, but it still requires some auxiliary operations by the operator. This punching machine is suitable for small and medium batch punching operations.
Fully automatic leather perforating machine:
The fully automatic leather perforating machine uses advanced CNC technology to achieve high-precision and high-efficiency punching operations. It can automatically complete punching, discharging and other processes according to preset programs without manual intervention. This punching machine is suitable for large-volume punching operations and can significantly improve production efficiency and product quality.
Laser leather perforating machine:
Laser leather perforating machine uses laser technology to perform punching processing, which has the advantages of high precision, no contact, and strong adaptability. It is suitable for leather punching operations of various materials and shapes, and is especially suitable for complex patterns and small batch customized production needs.
3. Operation process of leather perforating machine
Whether it is a mechanical perforating machine or a laser perforating machine, the operating process is roughly the same. The following is a typical leather punching machine operation process:
Preparation work: First, the leather material to be processed and the corresponding mold (or laser parameters) need to be prepared. At the same time, check whether all parts of the punching machine are working properly to ensure that the machine is in good working condition.
Securing the leather: Place the leather material on the punching machine’s table and secure it using clamps or pressure plates. Make sure the leather material is flat and wrinkle-free for accurate punching.
Set parameters: Set the working parameters of the punching machine according to the processing requirements and the characteristics of the leather material. These parameters may include punching diameter, punching spacing, punching depth, punching speed, etc.
Start the machine: Press the start button to start the punching machine for punching processing. During the processing process, operators need to pay close attention to the operating status of the machine to ensure punching quality and safety.
Check the quality: After the punching is completed, the quality and effect of the punching need to be checked. The inspection content includes the flatness and accuracy of the holes, whether there are burrs or tears, etc. If problems are found, parameters need to be adjusted or repaired in time.
Cleaning and finishing: After the punching operation is completed, the workbench and mold (or laser head) need to be cleaned to ensure that the machine and tools are clean and intact. At the same time, the processed leather materials are organized and stored for subsequent processing and use.
4. The importance of leather perforating machines in the leather processing industry

Improve production efficiency: The leather punching machine can automatically complete the punching operation, greatly improving production efficiency. Compared with traditional manual punching methods, mechanical punching machines and laser punching machines can complete a large number of punching operations faster, reducing labor costs and time costs.
Ensure processing quality: The leather punching machine uses precise mold or laser parameters for punching processing, which can ensure the flatness, accuracy and consistency of the holes. This helps improve the quality and aesthetics of leather products and meets consumer demand for high-quality products.
Promote product innovation: As consumers’ demand for personalized and differentiated products continues to increase, leather punching machines provide more possibilities for the innovation of leather products. By adjusting the mold shape, size and laser parameters, punching processing of various complex patterns and shapes can be easily realized, providing more creative space for product design.
