What level of dimensional accuracy can mold parts module achieve?
Publish Time: 2024-12-18
In the field of precision engineering of mold manufacturing, the dimensional accuracy of mold parts module is undoubtedly at the core, and the level it can achieve directly determines the quality of the mold and the quality of the final product.
The dimensional accuracy of modern mold parts module can usually reach the micron level or even higher. Taking some high-end precision molds as an example, the dimensional tolerance of its key parts module can be controlled within ±5 microns. This amazing high precision is achieved through a series of advanced manufacturing processes and precision equipment. In the processing link, high-precision CNC machining centers are widely used. The ultra-precision spindles and high-resolution control systems equipped with them can ensure that the tool performs extremely fine cutting on the material and control the dimensional error within a very small range. For example, when milling the complex curved surfaces of mold parts, the CNC machining center can accurately control the tool path and cutting depth according to the preset program, so that the surface flatness and dimensional accuracy after processing meet the strict requirements.
Electrospark machining is also one of the important means to achieve high precision. For some mold parts modules with extremely high hardness, complex shapes and difficult to process by traditional cutting, EDM uses the discharge phenomenon between the electrode and the workpiece to gradually remove the material and achieve fine processing at the micro level. By precisely controlling the discharge energy, pulse frequency and other parameters, micron-level tiny features such as micropores and narrow grooves can be processed on the module with extremely high dimensional accuracy.
In addition, advanced measurement technology is indispensable to ensure the dimensional accuracy of mold parts modules. The three-dimensional coordinate measuring machine can comprehensively and accurately detect the three-dimensional dimensions of the module, and its measurement accuracy can reach micron or even sub-micron level. By frequently using the three-dimensional coordinate measuring machine for sampling and feedback during the processing process, the processing errors can be discovered and corrected in time to ensure that each accessory module can meet the precision standards required by the design.
This high-precision dimensional control of mold parts modules has a decisive influence on the performance of the mold. For example, in injection molds, high-precision core and cavity modules can ensure the uniformity of the wall thickness of plastic products, avoid defects such as flash and lack of material, thereby improving the appearance quality and mechanical properties of the product. In stamping dies, precise punch and die dimensional accuracy can ensure the dimensional consistency and shape accuracy of stamping parts, reduce scrap rate and improve production efficiency.
The dimensional accuracy of mold accessories module is at the micron level or even higher. This is the result of the continuous development and innovation of modern mold manufacturing technology, and it is also a key factor in promoting product quality improvement and production efficiency improvement in many industrial fields.
