  • Mold adhesion(sticking to mold)

    Mar 07, 2017· If surface defects, such as grooves, nicks, cuts and/or dents exist in the mold cavity/runner, the molded parts tend to stick in the mold, leading to release failure. As a result, one of the main tasks is to improve the degree of the polish for the mold cavity and runner. It is better than the inner surface of the mold cavity is chrome plated.


  • Biomaterial Surface Modifications - Wikipedia

    The fluorine-carbon bond is largely ionic, producing a strong dipole. The dipole prevents Teflon from being susceptible to Van der Waals forces, so other materials will not stick to the surface. Teflon is commonly used to reduce friction in biomaterial applications such as in arterial grafts, catheters, and guide wire coatings.
