How to ensure the tensile strength of silicone injection products?

Introduction

6

Silicone injection products are widely used in medical, electronic, and industrial sectors, where tensile strength is strictly required. Ensuring tensile strength not only extends service life but also determines application reliability. The choice of process and formulation directly affects silicone’s mechanical properties.

During production, raw material purity, mold design, and process control are all critical factors. Through professional process optimization, we help customers improve product durability and stability. Stable production parameters not only reduce defect rates but also enhance competitiveness.

How to Choose the Right Silicone Material?

The performance of raw silicone materials directly impacts tensile strength. Choosing high-quality silicone minimizes molecular chain breakage. By comparing different hardness levels and molecular structures, the best-fit solution can be found. In practice, the right combination of material and formulation is the foundation of quality.

  • High-Purity Silicone: Higher purity means more stable tensile strength.
  • Reinforced Silicone: Nano-fillers improve strength and flexibility.
  • Medical-Grade Silicone: Ensures biocompatibility for demanding sectors.
  • Customized Formulation: Tailored hardness and durability for customer needs.

 Material selection lays the foundation for tensile strength performance

How to Optimize Injection Molding Parameters?

Temperature, pressure, and cooling speed in injection molding all affect silicone tensile strength. Unstable processing leads to stress concentration and chain breakage. Parameter optimization can significantly improve stability and performance.

  • Temperature Control: Accurate heating reduces uneven vulcanization.
  • Pressure Adjustment: Proper injection pressure avoids bubbles and cracks.
  • Cooling Rate: Uniform cooling prevents localized stress.
  • Flow Channel Optimization: Improves material flow and consistency.

 Optimizing process parameters is a key factor in enhancing tensile strength

How to Enhance Strength Through Structural Design?

Proper mold and product structural design effectively disperse stress and avoid stress concentrations. Ribs, rounded transitions, and uniform wall thickness can significantly improve tensile performance. At the design stage, structure determines long-term durability.

  • Rounded Corners: Prevent stress concentration at sharp edges.
  • Reinforcement Ribs: Increase overall tensile resistance.
  • Uniform Wall Thickness: Reduces localized deformation.
  • Mold Optimization: Flow simulation enables smarter structural design.
