(1) There are many types of template profiles, complex shapes, and large size changes. Therefore, molds with different specifications, different structures, and different forms are required to form and size, shape and position accuracy, and a lot of test work is required.
(2) The template requires industrial mass production, the first key is to improve the service life of the mold.
(3) The width and thickness ratio of the flat wide template profile is greater than 100 or more, and the dimensional accuracy and plane gap of the wide and thin siding parts require a special structure of the broadening and diverting mold to reasonably distribute the metal flow to the profile Forming and high-precision dimensional requirements, especially high-precision shape and position tolerances, are more technically difficult.
(4) Semi-hollow profiles in template profiles are mostly, the tongue ratio is greater than 5, the precision of size and shape requirements is ultra-high precision, a mold with a special structure can be used to form the profile and achieve high precision, and the mold must have sufficient Strength, no deformation, no cracking, no crushing life.
(5) The profile of the template requires a smooth surface, high size, shape and position accuracy. Therefore, it is necessary to use high-quality mold steel and strict mold heat treatment processes and machining to implement CNC process regulations in order to obtain high toughness, high precision, low Surface roughness mold.
