Compression molding ensures that the rubber material is evenly distributed and cured throughout the product. This uniformity is difficult to achieve with wrapping, which can result in variations in thickness and density, leading to potential weak points and inconsistencies in performance.
The high pressure and heat applied during compression molding result in a more homogeneous and structurally sound product. Wrapped rubber tubes may have seams or overlaps that can compromise their integrity and lead to premature failure under stress.
Compression molded products typically have a smoother and more uniform surface finish compared to wrapped products. This is important for applications where surface quality is critical, such as in sealing and gasket applications.
Compression molded rubber rods and tubes exhibit superior mechanical properties, such as greater tensile strength, elongation, and toughness. These properties are essential for applications that require high resilience and the ability to absorb shocks and vibrations.
For research and development (R&D) projects, it is often more advantageous to machine and trial the product from a molded billet rather than a wrapped product. This approach allows for more accurate testing and evaluation of the material’s properties and performance. If the project moves into production, the transition to compression molding from a molded billet is more seamless and ensures that the final product maintains the same high standards of quality and consistency.
