Fluorosilicone Fluid: A Technical Solution for Solving the Demolding Challenge of Precision Molds

Hits: 172 img

I. Industry Pain Points and Demand Background

Against the backdrop of intelligent manufacturing upgrades by 2025, precision molds (such as medical device/optical lens molds) will place higher demands on the demolding process:

Adhesion damage rates reach 12%-15% (industry research data)
Traditional mold release agents suffer from residual contamination and insufficient temperature resistance (<150°C)

Microstructure molds (<0.1mm precision) are sensitive to lubricant viscosity

II. Advantages of Fluorosilicone Fluid Solutions
1. Breakthrough Material Properties

Molecular Structure: Trifluoropropyl side chains impart an ultra-low surface tension of 18mN/m
Performance Parameters:

│ Indicator │ Value │
│---|---│
│ Operating Temperature │ -60~250°C │
│ Dynamic Friction Coefficient │ 0.05-0.08 │
│ Film Thickness │ 0.5-2μm │

2. Quadruple Action Mechanism
Physical Isolation: Nano-scale fluorosilicone membrane blocks material penetration
Chemical Inertness: Resists corrosion from injection molding materials (e.g., PC, TPU)
Thermal Stability: Maintains lubricity under rapid temperature fluctuations
Process Compatibility: Supports automated sizing methods such as spraying and dipping

3. Empirical Results and Implementation Recommendations
Case Study (Automotive Sensor Mold)
│ Indicators │ Traditional Process │ Fluorosilicone Oil Solution │
│---|---|---│
│ Release Force │ 320N │ 85N │
│ Yield │ 83% │ 98.7% │
│ Mold Maintenance Cycle │ 200 cycles │ 1500 cycles │

Application Considerations
Pretreatment Requirements: Molds must be plasma cleaned (Ra ≤ 0.2μm)
Concentration Control: Recommended dilution to 0.5%-1.2% (v/v)
Contraindications: Avoid mixing with phosphorus-containing release agents
