1. High-Frequency (HF) Embossing Machines
Principle:
Utilizes a high-frequency electromagnetic field (e.g., 27.12 MHz) to induce polarization and molecular friction heating in materials like PVC and TPU. Combined with mold pressure, this achieves embossing, welding, or edge cutting.
Advantages:
- High welding efficiency with a narrow heat-affected zone.
- Ideal for 3D embossing on large-area carpets, such as anti-slip patterns or brand logos for automotive floor mats.
2. Hydraulic/Pneumatic Embossing Machines
Principle:
Applies pressure via hydraulic/pneumatic systems, paired with heated plates for flat embossing.
Advantages:
- Uniform pressure distribution, suitable for thick materials.
- Requires preheating and operates at lower efficiency compared to HF machines.
Representative Model:
- Puxiong PXAI-P10P: Adjustable hydraulic pressure system with a working area of 2000×1200 mm and 75 kW power, designed for large automotive seat cushions (EVA/PVC materials).
3. Application Scenarios and Advantages
Automotive Interior Applications
- Floor Mat Embossing:
- HF machines achieve 3D anti-slip patterns and brand logos (e.g., Puxiong AUTO series for PVC mats, achieving a yield rate up to 99%).
- Seat Cushion/Carpet Embossing:
- Hydraulic models like the Puxiong PXAI-P10P ensure uniform pressure and prevent deformation during large-area EVA cushion embossing.
Home Furnishing Applications
- Doormat/Carpet Embossing:
- HF machines (e.g., Puxiong AUTO-P11P) synchronize anti-slip patterns and branding on PVC mats, boosting efficiency by 40% over traditional heat pressing.
Industrial Customization
- Large-Scale Outdoor Carpets:
- Customized Puxiong AUTO-P11P supports 2000×1200 mm dimensions and 35 kW pressure, meeting wear-resistant embossing demands for outdoor carpets.
