The molds, which include multi-station progressive dies, injection molds, and cold heading dies, are widely used in demanding industries such as automotive parts, consumer electronics, and micro-precision fasteners. The new generation of molds utilizes ultra-high-precision steel (SKD11/DC53) and nano-coating technology, combined with fully closed-loop CNC machining and precision EDM processes, significantly improving the mold's wear resistance, corrosion resistance, and service life. Intelligent computer-aided engineering (CAE) technology optimizes the structural design, increasing production efficiency and product tolerance stability by over 30% compared to traditional molds. Henghui's technical director said: "The full set of molds produced in this mass production achieves micron-level precision control, which is particularly suitable for the stable mass production of complex structural parts. We are committed to providing customers with one-stop solutions from mold design, manufacturing to commissioning, enabling the industry chain to reduce costs and increase efficiency." Currently, this batch of molds has passed the acceptance inspection of several leading companies in the industry and has been put into mass production, with excellent feedback. Chongqing Henghui will continue to deepen its roots in the field of precision manufacturing, using technology to inject new momentum into China's intelligent manufacturing.

I. Preliminary Heat TreatmentFor hypereutectoid steel stamping die forgings, normalizing should be performed first, followed by spheroidizing annealing to eliminate the network-like secondary cementite within the forgings, refine the grain structure, relieve internal stresses, and prepare the microstructure for subsequent heat treatment. Before quenching the stamping die parts (such as concave dies), low-temperature tempering should be conducted first. For dies with more complex shapes and high precision requirements, quenching and tempering treatment should be carried out after rough machining and before finish machining to reduce quenching deformation, minimize the tendency for cracking, and prepare the microstructure for the final heat treatment. II. Optimization of Quenching and Tempering Processes Protection of Parts During QuenchingQuenching and tempering are critical steps that affect the deformation or cracking of stamping die parts during heat treatment. For areas of critical die parts prone to deformation or cracking during quenching, effective protective measures should be taken to ensure symmetrical part shapes and cross-sections, as well as balanced internal stresses. Improvement of Heating MethodsFor small stamping punches and dies or slender cylindrical parts, preheating to 520–580°C before placing them in a medium-temperature salt bath furnace for heating to the quenching temperature can significantly reduce deformation compared to direct heating in an electric or reverberatory furnace. This method also helps control the tendency for cracking. Especially for high-alloy steel die parts, the correct heating method involves preheating first, then raising the temperature to the quenching level. The duration of high-temperature exposure should be minimized during heating to reduce quenching deformation and avoid the formation of microcracks. Determination of Heating TemperatureExcessively high quenching temperatures coarsen austenite grains and cause oxidation and decarburization, increasing the tendency for deformation and cracking. Within the specified heating temperature range, if the quenching temperature is too low, the internal holes of the part may shrink, reducing the bore size. Therefore, the upper limit of the heating temperature range should be selected for carbon steels. For alloy steels, higher heating temperatures may cause expansion of internal holes and an increase in bore size, so the lower limit of the heating temperature range is preferable. Selection of Cooling MediaFor alloy steels, the best method to minimize quenching deformation is isothermal quenching or martempering in a hot bath of potassium nitrate and sodium nitrite. This method is particularly suitable for stamping dies with complex shapes and precise dimensional requirements. For some porous die parts, the isothermal quenching time should not be too long, as it may cause an increase in hole diameter or pitch. Utilizing the characteristics of shrinkage during oil cooling and expansion during nitrate salt cooling, and applying dual-medium quenching appropriately, can reduce part deformation. Optimization of Cooling MethodsBefore placing parts into the cooling medium after removal from the heating furnace, they should be appropriately air-cooled first. This is one of the effective methods to reduce quenching deformation and prevent cracking. After placing the die parts into the cooling medium, they should be rotated appropriately, with changes in rotation direction, to ensure uniform cooling rates across all parts of the component. This significantly reduces deformation and prevents cracking. Control of Tempering ProcessAfter removal from the cooling medium, die parts should not be left in the air for too long but should be promptly placed into a tempering furnace for tempering. During tempering, low-temperature and high-temperature temper brittleness should be avoided. For die parts with high precision requirements, multiple tempering treatments after quenching can help relieve internal stresses, reduce deformation, and minimize the tendency for cracking. Heat Treatment Before Wire CuttingFor stamping die parts processed by wire cutting, graded quenching and multiple tempering treatments should be applied before wire cutting to improve the hardenability of the parts, ensure uniform distribution of internal stresses, and maintain a state of low internal stress. The lower the internal stress, the less the tendency for deformation and cracking after wire cutting.

The main manufacturing process of fasteners includes: raw material procurement → re-inspection → blanking → cold heading or hot forging (bolts and nuts) → heat treatment → performance test → machining → wire rolling forming → table Surface treatment → surface inspection → NDT → dimension inspection → packaging and transportation and other processes. A large number of fatigue failure analysis results of high-strength bolts show that more than 70% of fatigue failure results from surface damage, decarburization at the joint of head and rod, obvious small cracks in thread processing or machining Discontinuities in knife marks, surface corrosion and quenched structure are not uniform because of high stress concentration there. Therefore, the promotion and implementation of the new standard GB/T3098.23, 24 and 25 need to be made great efforts, It is suggested that fastener quality management should be strengthened and optimized from design, procurement, manufacturing, installation, non-conformance management, inspection and test. In short, the fastener design should strengthen the universality and standard Standardization and identification code, procurement should limit the lowest bidding price, manufacturing inspection can take into account the third-party inspection unit's responsibility for multiple parties, installation strengthening records and operation according to standards, and strengthen the cause analysis of non-conformance management And experience feedback, inspection and re-inspection are parallel.
