High-Pressure Molding VS Low-Pressure Molding: The Ultimate Choice in Wire Harness Encapsulation Technology

1. Core Applications of High-Pressure Molding

• Precision Electronics: Encapsulation of 0.4mm pitch connectors with tolerances of ±0.02mm.

• Automotive Sensors: PPS encapsulation housings resistant to oil corrosion (withstanding temperatures up to 200°C).

• Military Equipment: Integrated electromagnetic shielding layers (attenuation >60dB).

• Case Study: An ECU wire harness housing for an automotive manufacturer achieved IP69K waterproof rating through high-pressure molding.

2. Advantages of Low-Pressure Molding

• Flexible Wire Harnesses: 360° wrapping with TPU material, achieving a bending lifespan of over 500,000 cycles.

• Medical Cables: Low-temperature process protects silicone insulation layers (withstands 134°C sterilization).

• Outdoor Equipment: 2mm uniform coating resists UV aging (passes 3,000-hour testing).

• Case Study: AGV robot drag chain wire harnesses saw a 73% reduction in failure rates with low-pressure molding.

3. Decision-Making Tree: 4 Steps to Identify the Optimal Process

Step 1: Evaluate Environmental Requirements

• High-temperature/high-corrosion environments → High-pressure molding

• Flexible/frequent bending scenarios → Low-pressure molding

Step 2: Assess Structural Complexity

• Multi-rib/thin-wall structures → High-pressure molding

• Simple geometric shapes → Low-pressure molding

Step 3: Calculate Comprehensive Costs

• High-volume standardized parts → High-pressure molding (efficiency advantage)

• Low-volume custom parts → Low-pressure molding (lower mold costs)

Step 4: Verify Material Properties

• High-temperature-resistant engineering plastics → High-pressure molding

• Elastomers/biocompatible materials → Low-pressure molding

By carefully considering these factors, Kable-X ensures the optimal molding process is selected, delivering wire harness solutions that meet the highest standards of performance and reliability.
