1. Cutting Process
- Accurate Measurement: Before performing skiving, precise measurement of both the leather and the substrate is crucial to determine the required size and shape. Professional tools like tape measures and calipers are often used for this purpose.
- Cutting Methods: Based on the measurements, leather is cut into the desired shape using knives or cutting devices. Ensuring clean, smooth edges and avoiding frayed or irregular shapes is vital. For complex shapes, templates or CNC cutting equipment can enhance precision and efficiency.
2. Adhesion Process
- Adhesive Selection: Choosing the right adhesive is key to the quality of the skiving process. The adhesive should have excellent bonding properties, as well as resistance to water, heat, and aging. Depending on the materials involved, suitable adhesives include hot-melt glue, solvent-based adhesives, or water-based adhesives.
- Adhesion Methods: Leather is bonded to the substrate either manually or mechanically. Manual bonding requires skill and experience to ensure a tight, bubble-free fit. Mechanical bonding can improve efficiency and quality, particularly in large-scale production.
3. Punching Process
- Functional Requirements: Some skived products may require punching for hardware installation or ventilation. The position and size of the holes should be determined based on design requirements, ensuring that the overall structure and appearance of the product are not compromised.
- Punching Methods: Punching can be done using punch machines or presses. It is important to control the force and depth to avoid damaging the leather or substrate. Advanced techniques like laser cutting may be used for special shapes.
4. Embossing Process
- Decorative Effects: Embossing can create various patterns and textures on the leather surface, enhancing the decorative and artistic appeal of skived products. Patterns can be customized according to client needs or produced using existing embossing molds.
- Embossing Methods: Embossing typically involves a press machine where leather is placed on a work table. Through heating and pressure, the desired patterns and textures are formed. Parameters like temperature, pressure, and time should be adjusted based on the leather’s material and thickness to ensure quality and stability of the embossing effect.
5. Dyeing Process
- Color Adjustment: Leather dyeing can be performed either before or after the skiving process to achieve richer and more personalized colors, meeting various design needs.
- Dyeing Methods: Traditional dyeing methods include immersion and spraying, while modern techniques such as digital printing are also available. It is crucial to select appropriate dyes and techniques to ensure that the color is uniform, durable, and resistant to fading.
These processes complement skiving and contribute to the overall quality and functionality of the finished product. Proper execution and attention to detail in each step are essential for achieving the best results.
