Treatment Method for Mold Tool Surface |
摘要 |
The average roughness Ra of a mold tool surface that comes into contact with a material to be molded measured for a measurement area 10 mum square or smaller is equal to or lower than 5 nm, and fine granular projection structures having diameters ranging from 10 to 80 nm and heights ranging from 10 to 40 nm are formed on the mold tool surface with a density of 400 /mum2 or higher. The frictional force due to the anchoring effect or the digging effect is reduced, and the adhesive force due to meniscus is also reduced. The release resistance is significantly reduced without affecting the dimensional precision of a fine molded product.
