The car seat embossing machine is a device used to emboss specific patterns or designs on car seat fabrics (such as leather, fabric or artificial leather), and is widely used in the field of automobile interior manufacturing. Through the embossing process, the beauty, anti-slip and comfort of the seat can be improved. The following is a detailed explanation of the working principle, operation process, required materials and precautions of the embossing machine.
1. Working principle
The car seat embossing machine mainly achieves the embossing effect through hot pressing or high-frequency welding technology. The specific principle is as follows:
Hot pressing principle
Heating and pressure: The embossing machine heats the mold to a certain temperature (usually 100-200℃) through a heating plate, and applies pressure (usually 10-50 tons) at the same time to soften the seat fabric under high temperature and high pressure.
Mold molding: The surface of the mold is engraved with concave and convex patterns. When the fabric contacts the mold, the pattern is embossed onto the fabric and is shaped after cooling.
Applicable materials: Applicable to PVC, PU leather, fabric and other materials.
Principle of high-frequency welding
High-frequency electromagnetic field: The embossing machine uses high-frequency electromagnetic field to make the molecules inside the material vibrate, generate heat, and soften the material.
Pressure molding: Apply pressure while heating with high frequency to make the material fit the mold and form a pattern.
Applicable materials: Suitable for composite materials with PVC or PU coating.
2. Operation process
The operation process of the car seat embossing machine usually includes the following steps:
Preparation work
Check the equipment: Make sure that the embossing machine is in normal working condition, and check whether the heating system, pressure system, and mold are intact.
Prepare materials: Cut the seat fabric into the required size and ensure that the surface is flat and wrinkle-free.
Preheat the mold: Set the heating temperature according to the material type and preheat the mold to the specified temperature.
Place the material
Place the fabric flat on the lower mold of the embossing machine to ensure accurate position and avoid offset.
Start embossing
Start the embossing machine, the upper mold descends, closes with the lower mold, applies pressure and maintains it for a certain time (usually 5-30 seconds).
During this process, the fabric is heated and softened, and the pattern of the mold is embossed onto the fabric.
Cooling and shaping
After embossing is completed, the mold remains closed and the fabric is allowed to cool naturally or accelerated by the cooling system to shape the pattern.
Removing the finished product
After cooling, the upper mold rises and the embossed seat fabric is taken out to check whether the pattern is clear and defect-free.
Subsequent processing
The embossed fabric is subjected to subsequent processing such as cutting and sewing, and finally used in the production of car seats.
