(1) There are many varieties of formwork profiles, complex shapes and large dimensional changes. Therefore, it is required to design and manufacture high-quality molds of different specifications, different structures and different forms to ensure the forming, size and shape accuracy, and a large amount of experimental work is required.
(2) The template requires industrialized mass production, the first key is to improve the service life of the mold.
(3) The width and thickness ratio of the flat and wide stencil profiles are more than 100, and the dimensional accuracy and plane clearance of the wide and thin slabs are difficult to guarantee. A special structure of wide-spreading and splitting dies is needed to properly distribute the metal flow. In order to ensure the forming and high-precision dimensional requirements of the profile, especially to ensure ultra-high precision shape tolerance, the technical difficulty is greater.
(4) Most of the semi-hollow profiles in the formwork profile, the tongue ratio is greater than 5, the accuracy of the size and shape requirements is ultra-high precision, and a special structure of the mold is required to ensure the profile forming, and to achieve high precision, and to ensure the mold It has sufficient strength, no deformation, no cracking, no collapse, and high service life.
(5) The template profile requires high surface smoothness, high dimensional and dimensional accuracy. Therefore, it is necessary to use high-quality die steel and strict mold heat treatment process and machining to implement all CNC process specifications in order to obtain high strength, high toughness and high precision. High quality mold with low surface roughness.
