In the mold manufacturing industry, precision mold is the highest technical content, the highest value-added, the application of the most core categories, mainly used in high-end consumer electronics, automotive, medical equipment, aerospace and other areas requiring high product precision, its dimensional accuracy is usually controlled at the micron level, the surface finish, structural stability, service life, and other indicators are far more than ordinary molds. Precision mold manufacturing level, a direct reflection of the core competitiveness of the mold enterprise, but also to determine the quality of high-end products downstream key factors. In the transformation of the industry to high-end, master the core technology of precision molds, the establishment of a perfect quality control system, is a mold enterprise based on high-end market, to achieve sustainable development of the fundamental.<\/p>\n\n\n\n
The core of precision mold manufacturing, lies in the whole process of technical control, from design, materials, processing to assembly, debugging, testing, each link can not tolerate the slightest deviation, the core technology breakthroughs and process optimization, is to enhance the quality of the key precision mold. First of all, precision mold design technology is the source of the core, the slightest mistake in the design process will lead to irreversible defects in subsequent processing. Precision mold design to abandon the traditional two-dimensional design, the full use of three-dimensional parametric design, combined with CAE simulation technology, the mold structure, pouring system, cooling system, ejector system for all-round optimization, in advance to simulate the product molding process, analysis of the stress distribution, deformation, melt flow state, to avoid structural defects and molding problems. At the same time, the modular design concept is adopted to enhance the versatility and interchangeability of mold parts, simplify the assembly and maintenance process, and extend the service life of the mold.<\/p>\n\n\n\n
The selection of mold materials and heat treatment technology is the key to determine the performance and life of precision molds. Precision molds are in a long-term high-pressure, high-temperature, friction working environment, the hardness of the material, wear resistance, corrosion resistance, toughness requirements are extremely high, ordinary mold steel can not meet the demand. High-end precision molds are usually imported high-quality die steel, high-strength alloy tool steel, powder metallurgy steel and other high-performance materials, such as uniform organization of the material, stable hardness, wear resistance, can effectively reduce mold wear and tear, and enhance the molding accuracy. Heat treatment technology is to enhance the mold material performance of the core process, through the vacuum quenching, deep cold treatment, nitriding treatment and other advanced processes, precise control of the hardness and toughness of the material, to avoid deformation and cracking of the material, to ensure that the mold in the long-term high-frequency use of the mold to maintain the dimensional stability of the service life of the mold than the ordinary to enhance the 30% or more.<\/p>\n\n\n\n
Precision machining process and high-end equipment is the core guarantee to realize micron-level precision. Complex surfaces, microscopic holes and high-precision cavities of precision molds need to rely on high-end CNC equipment and advanced processing technology to complete. Five-axis linkage high-speed machining center is the core equipment for precision mold processing, which can achieve one-time high-precision processing of complex surfaces, avoiding errors brought about by multiple clamping; slow-feeding wire cutting, EDM, can complete the micro-structure, narrow slits, shaped cavities precision processing, machining accuracy up to the micron level; precision grinding, polishing process, to ensure that the mold surface finish to reach the level of the mirror to meet the appearance and molding requirements of high-end products. The precision grinding and polishing process ensures that the surface finish of the mold reaches mirror level, which meets the appearance and molding requirements of high-end products. At the same time, the processing process adopts constant temperature workshop design, avoiding the thermal expansion and contraction error caused by the temperature change of the material, and strictly controlling the processing environment throughout the whole process, which further guarantees the processing precision.<\/p>\n\n\n\n
Assembly and debugging technology, is the last hurdle of precision mold molding effect, but also an important link to test the technical strength of enterprises. Precision mold parts are extremely high precision, the assembly process requires professional technicians to operate manually, strictly control the parts of the fit gap, coaxiality, parallelism, to ensure smooth operation of all parts. Trial mold debugging stage, through a number of trial production, accurate adjustment of mold temperature, pressure, open and close the mold speed and other parameters, optimize the molding process, to ensure that the product size, appearance, performance is fully up to standard, to prevent the mass production of defective products. For complex precision molds, it is often necessary to optimize the molding process after many fine-tuning to achieve the best molding results, which relies on the rich experience and rigorous attitude of the technicians.<\/p>\n\n\n\n
Perfect quality control system is the core support of stable quality of precision molds, which runs through the whole process from order receiving to mold delivery. The establishment of the whole process of quality control mechanism, design review of drawing accuracy and simulation results; hardness and composition testing of materials before warehousing to prevent unqualified materials into the production; real-time detection of dimensional accuracy of parts in the processing process, each process can only be qualified to enter the next link; assembly is completed to carry out a comprehensive accuracy testing and mold testing, testing and inspection report issued after passing the test before delivering to the customer. At the same time, the establishment of a quality traceability system, record each set of mold design parameters, processing technology, material information, quality inspection results, once the quality problem, can quickly locate the root cause, accurate rectification. In addition, regular calibration and maintenance of equipment to ensure the precision of equipment operation, to avoid equipment errors affect the quality of the mold.<\/p>\n\n\n\n
In the high-end manufacturing demand continues to grow, the precision mold market demand continues to rise, but the industry competition also focuses on technology and quality of the competition. For mold enterprises, the low-end market price war has no way out, the only way to plough the field of precision molds, to overcome the core technology, optimize the processing technology, the establishment of a stringent quality control system in order to create irreplaceable core competitiveness. In the future, precision mold manufacturing will move towards higher precision, higher efficiency, longer life of the direction of development, only adhere to the quality first, technology first enterprise, in order to stand firm in the high-end mold market, to win the trust of customers, and to promote China's mold industry from a manufacturing power to a manufacturing power.<\/p>","protected":false},"excerpt":{"rendered":"
