The high-frequency embossing machine for car seat cushions is a specialized piece of equipment that utilizes high-frequency electromagnetic waves (typically 27.12MHz or 40.68MHz international industrial bands) to generate heat and pressure for 3D embossing, welding, and sealing on car seat cushion materials such as leather and sponge. The following is a detailed introduction to this equipment:
I. Working Principle
* **High-Frequency Electromagnetic Field Generation:** Through a high-frequency oscillation circuit, an electron tube (such as a vacuum tube) generates high-frequency electromagnetic waves, forming a strong electromagnetic field between the metal mold and the material.
* **Molecular Friction Heating:** The electromagnetic field polarizes the molecules within the material (such as PVC, TPU, EVA, leather, etc.), generating high-speed frictional heat that melts the material surface.
* **Pressure Molding:** Under mold pressure, the molten material is pressed into a three-dimensional texture, forming a durable pattern or seam after cooling.
II. Core Features
* **High-Efficiency Processing:** Completes complex pattern embossing in a short time, improving production efficiency.
* **Precise Control:**
* **Temperature:** A stepless heating device allows for adjustable mold temperature to adapt to different material properties.
**[Further details on core features]** Pressure: Adjustable head pressure ensures uniform embossing depth.
Time: Flexible processing control via a time controller (descent, welding, cooling time).
Safety Protection:
Spark Suppression: Equipped with a highly sensitive spark protection device that automatically cuts off current to prevent mold damage.
Overload Protection: Automatic power cut-off when current is too high, protecting the electron tube and rectifier.
Grounding Design: Ensures safe operation and avoids the risk of electric shock.
Multifunctionality: Supports various processes such as embossing, welding, sealing, and cutting.
Suitable for processing single-layer or multi-layer materials (e.g., leather and sponge composites).
III. Application Areas
Automotive Interiors: Seat cushions, steering wheel covers, sun visors, door panel embossing.
Leather Products: Shoe uppers, bags, clothing embossing and label production.
Medical Supplies: Disposable infusion bags, urinary catheter bags, medical cooling pad sealing.
Home Furnishings: Carpets, curtains, mattress embossing.
Other Areas: Inflatable toys, stationery, electronic product packaging, etc.
IV. Equipment Types
Single-Head Push-Plate Type: Compact structure, suitable for small-batch production.
Power Range: 5KW-8KW.
Operation Method: Manual or foot pedal.
Double-Head Hydraulic Type: Dual-station design, improving production efficiency.
Power Range: 10KW-15KW.
Suitable for large-scale production.
Automatic Slide Table Type: High degree of automation, reducing manual intervention.
Equipped with a PLC control system, supporting complex process settings.
Synchronous Welding Machine: Embossing and cutting are completed simultaneously, improving processing accuracy.
Suitable for multi-layer material composite processing.
V. Purchase Recommendations
Power Selection:
Small-Scale Production: 5KW-8KW equipment is sufficient.
Large-Scale Production: Recommended equipment of 10KW or higher for improved efficiency.
Frequency Stability: Prioritize equipment conforming to international industrial band standards (e.g., 27.12MHz) to ensure processing quality.
Mold Compatibility: Confirm whether the equipment supports customized molds to adapt to different product design requirements. After-sales service: Choose a supplier that provides technical support, mold maintenance, and training to reduce later usage costs.
