- High technical requirements: The leather covering process requires skilled technicians to operate, especially in areas with high precision and quality requirements, such as high-end automotive interiors and luxury goods. For example, in automotive interiors, the leather must be accurately applied to complex-shaped interior parts, ensuring proper adhesion, smoothness, and consistency of texture. This demands high technical proficiency and experience from the workers, or else issues like uneven covering, bubbles, and wrinkles may occur.
- Complicated processing steps: The leather covering process usually involves multiple steps, including cutting the leather, pre-treatment, bonding with the substrate, and edge finishing. Each step requires strict control; otherwise, it can affect the final covering effect. For example, in furniture manufacturing, the size of the leather must be precisely calculated, the amount of glue applied and drying time must be well controlled during the bonding process, and the edges require detailed manual handling. All of this increases the complexity of the process and extends the production cycle.
In terms of material adaptability:
- Substrate limitations: Not all substrates are suitable for the leather covering process. Factors such as the surface smoothness, roughness, and material of the substrate will affect how well the leather adheres. For example, for substrates that are too rough, the leather may not adhere tightly, leading to hollow spots; for some substrates that are incompatible with leather, special treatment or specific adhesives may be required, adding to the complexity and cost of the process.
- Leather selection limitations: Different types of leather have different characteristics, such as thickness, softness, elasticity, and breathability, which also affect the application of the leather covering process. For instance, thicker or harder leathers may crack or deform when bent or applied to objects with complex shapes; leathers with poor breathability may affect the heat dissipation of the covered objects during long-term use.

- High raw material cost: High-quality leather is expensive, especially rare animal hides or specially treated leather, which increases the cost of the leather covering process. Additionally, the cost of special adhesives, coatings, and other auxiliary materials cannot be ignored, all of which add to the production cost.
- High equipment and mold investment: For large-scale leather covering production, specialized equipment and molds are required. For example, leather covering in automotive interior production requires large forming equipment and high-precision molds. These equipment and molds come with high investment costs and require regular maintenance and replacement, adding to the production burden for companies.
In terms of environmental impact:
- Adhesive pollution: Adhesives are commonly used in the leather covering process to bond the leather to the substrate. Some traditional adhesives may contain harmful substances, such as formaldehyde and benzene, which can release harmful gases during production and use, posing risks to the environment and human health. Although there are environmentally friendly adhesives available, their performance and cost may not yet fully meet production needs.
- Leather waste and recycling: The production and processing of leather generate a large amount of offcuts and waste. The disposal and recycling of this leather waste is a challenge. Improper disposal not only leads to resource wastage but can also cause environmental pollution.
In terms of design limitations:
- Shape and structure constraints: The leather covering process has certain limitations regarding the shape and structure of objects. Objects that are too complex or have sharp corners are difficult to cover or bond fully, limiting the scope of application for the leather covering process. For example, some electronic product housings with sharp angles or small curvature radii may experience issues such as leather cracking or poor adhesion during the covering process.
- Difficulty in matching colors and textures: If specific color and texture effects are required on the covered object, the inherent color and texture of the leather may be limiting. For example, some clients may request specific patterns or gradient color effects on the covered product, but the natural texture and color of the leather may not meet these requirements, requiring additional treatment or printing, which increases the complexity and cost of the process.
