TPU Film Surgical Robot Protective Sleeve Heat Sealing Machine: Technical Analysis and In-depth Guide to Industry Applications

I. Industry Context: Core Requirements

With the proliferation of surgical robots (e.g., Da Vinci System, Tiandi Orthopedic Robot) in minimally invasive surgeries, protective covers for robotic arms and optical systems demand:

• Aseptic Sealing: Block intraoperative fluid penetration (ISO 11607 compliance).
• Precision Fit: Adapt to complex 3D surfaces with >95% contour accuracy.
• Durability: Withstand 500+ cycles of plasma/EtO sterilization and mechanical abrasion.

Material Choice: Medical-grade TPU films (e.g., Covestro Platilon®) with:

• 92% light transmittance
• 300% elongation at break (ASTM D412)
• ISO 10993-5 biocompatibility certification

II. Welding Technology Comparison

Recommended Solution: HF welders achieve 99.9% leak-free joints while accommodating curved surfaces.

III. HF Welding Process Optimization (Shanghai Puxiong D04C)

1. Generator Design

• Frequency: 27.12 MHz (±0.05% stability)
• Power Range: 1-8 kW (adjustable for 0.1-3mm TPU)
• EMI Protection: <1 V/m interference at 30cm distance

2. Mold Engineering

• Material: 7075-T6 aluminum with 50μm hard chrome plating (3x wear resistance)
