1. List of required materials
1. Seat fabric
Natural leather: high-quality texture, often used in high-end models, but the cost is high.
Artificial leather (PVC/PU): cost-effective, wear-resistant and easy to clean, it is the mainstream choice.
Fabric: such as flannel and mesh, good breathability, often used on the side or back of the seat.
Composite materials: such as PVC coated fabric, suitable for high-frequency welding process.
Selection suggestion: Select fabric according to the model positioning and cost budget. PVC/PU leather is the most widely used due to its durability and cost advantage.
2. Embossing mold
Material: aluminum alloy (lightweight) or steel (durable), with patterns engraved on the surface.
Pattern type: stripes, grids, diamonds, brand LOGO, etc., can be customized according to design requirements.
Note: The mold needs to match the embossing machine model to avoid embossing failure due to size mismatch.
2. How to use the embossing machine
1. Preparation
Check the equipment:
Ensure that the power supply, heating system, and pressure system are normal.
Check whether the mold is firmly installed and not loose or damaged.
Preheating mold:
Set the heating temperature according to the type of fabric (such as PVC leather about 150-180℃).
Preheating time is about 10-15 minutes to ensure uniform mold temperature.
Prepare fabric:
Cut the fabric into the required size, with a flat surface and no wrinkles.
Fix the fabric position with high temperature resistant tape to avoid deviation during embossing.
2. Embossing operation
Place the fabric:
Place the fabric flat on the lower mold, ensuring that the pattern area is aligned with the mold.
Start embossing:
Start the embossing machine, the upper mold descends, closes with the lower mold, and applies pressure (usually 10-50 tons).
Maintain pressure and time (such as 15-30 seconds), the specific parameters need to be adjusted according to the thickness and material of the fabric.
Cooling and shaping:
After embossing is completed, keep the mold closed, cool naturally or accelerate cooling through the cooling system to ensure that the pattern is shaped.
3. Finished product inspection and subsequent processing
Check the pattern: Take out the fabric and check whether the pattern is clear, without bubbles or damage.
Cutting and sewing: The embossed fabric is cut, sewn and processed, and finally used in the production of car seats.
Cleaning the mold: After embossing, clean the mold in time to avoid residual materials affecting the next use.
