In the field of fashion accessories, bags are essential items for daily travel and matching, and their design and craftsmanship directly affect consumers’ purchasing decisions. Leather is one of the main materials for bag production, and its processing technology is particularly important. Among them, leather punching machine and technology can not only improve the beauty of bags, but also enhance their breathability and personalization. This article will introduce a punching solution for bag leather in detail, including design, tool selection, operation steps and precautions.
1-Design Pattern
1.1 Pattern selection
First, choose a suitable punching pattern based on the overall design style of the bag and the target consumer group. The pattern can be a simple geometric shape (such as circle, square, diamond, etc.) or a complex natural pattern, animal pattern or text pattern. The choice of pattern should take into account the coordination with the overall style of the bag and the aesthetic preferences of the consumer.
1.2 Pattern design
Use design software or hand-drawing to draw the selected pattern on paper or computer. During the design process, it is necessary to determine the size, position and arrangement of the holes of the pattern. At the same time, considering the ductility of the leather and the effect after punching, the pattern needs to be properly adjusted and optimized.
2-Choose the right leather punching machine
2.1 Mould Leather punching machine
For bags produced in large quantities, mould leather punching machines is an efficient choice. This equipment uses a high-precision micro-die structure, combined with high-precision punching needles and punching plates, to quickly and accurately complete the hole processing. Die punching machines are suitable for punching whole leather or cut leather.
2.2 CNC leather punching machine
For bags that require customized patterns or complex hole patterns, CNC leather punching machine is a better choice. This type of equipment integrates computer graphics, mold-free, and CNC processing. It can automatically generate controllable data based on CAD data to achieve diversified and personalized punching processing. CNC punching machines are suitable for small batch and multi-variety production needs.
2.3 Laser drilling machine
Laser punching technology, with its high precision and unique design features, provides another option for punching holes in leather bags. Laser punching machines can punch holes of various shapes and sizes on leather, and the edges of the holes are smooth and burr-free. Laser punching technology is suitable for bag production that requires high hole accuracy and aesthetics.
3- leather punch machine operation steps
3.1 Preparing leather materials
Cut the leather to be punched into the appropriate size and shape, and remove dust and impurities from the surface. Make sure the leather surface is flat and wrinkle-free for punching.
3.2 Pattern positioning
Place the designed pattern on the leather and fix it on the leather using positioning tools (such as positioning pins, positioning rulers, etc.). Make sure the pattern is positioned accurately and without offset.
3.3 Punching
Depending on the punching machine selected, follow the steps below to perform the punching process:
Mould leather punching machine: Place the leather on the workbench of the punching machine, adjust the position and depth of the die, and start the machine to punch.
CNC leather punching machine: Place the leather on the workbench of the CNC punching machine, input the CAD data and start the machine for automated punching.
Laser drilling machine: Place the leather on the workbench of the laser punching machine, adjust the focal length and power of the laser beam, and start the machine for laser punching.
3.4 Arrangement and inspection
After punching, remove the leather from the workbench and sort it. Check whether the size, position and shape of the holes meet the design requirements, and whether there are any damage or defects on the leather surface. If necessary, repair or reprocess it.
4-Precautions
4.1 Leather selection
When choosing leather, you need to consider factors such as its thickness, ductility and wear resistance. Different types of leather have different requirements for punching technology, so you need to choose the right leather material according to the actual situation.
4.2 Pattern design
When designing the pattern, you need to consider the ductility of the leather and the effect after punching. Avoid designing too complex or dense patterns to avoid causing the leather to deform or cracking the edges of the holes.
4.3 leather punching machine Operational safety
When punching, you need to strictly follow the safety operating procedures. Wear protective equipment such as protective glasses and gloves to prevent injuries caused by flying debris or machine failure.
4.4 Quality Control
During the punching process, strict quality control is required. The wear of the punching tools should be checked regularly and damaged parts should be replaced in time. At the same time, the quality of the processed leather should be checked to ensure that the size, position and shape of the holes meet the design requirements.
In summary, the bag leather punching scheme involves many aspects such as design pattern, tool selection, operation steps and precautions. Through scientific and reasonable scheme design and fine operation control, beautiful, breathable and personalized bag products can be produced.
