The utilization of cutting-edge processing technology is indispensable to the production of high-precision die-casting molds. Manufacturing die-casting molds involves a number of different processes, the most important of which are CNC milling, slow wire cutting, EDM, grinding, turning, measurement, and automation. The introduction of CNC milling technology has been a primary factor in the explosion of growth seen in the die-casting mold manufacturing sector in recent years. The traditional, ordinary milling machine gave way to the three-axis machining center, which was followed by today's five-axis high-speed milling. This advancement allowed for the processing of three-dimensional profile parts that were previously impossible, regardless of how complex they were. Additionally, the hardness of the material was no longer a limiting factor.

The CNC milling process is used to finish the plastic mold's primary cavity as well as the surface. Milling cutters with a small diameter are utilized in high-speed milling. The most common types of milling cutters used are solid carbide ball-end milling cutters, end mills, and corrugated milling cutters. The production efficiency is greatly improved by using small-cycle feeds at high speeds, and the accuracy can consistently reach 5 micrometers;Because of the low milling force, the thermal deformation of the workpiece is minimized, the milling depth is reduced, the feed rate is increased, and the surface finish is capable of reaching Ra0. 15 m. High-speed milling can work with parts made of hardened mold steel with a 60HRC rating. Because of this, high-speed milling enables cutting to take place after heat treatment, which greatly simplifies the process of manufacturing die-casting molds.

Processing two-dimensional and three-dimensional ruled surface parts, such as various punch dies, plastic molds, powder metallurgy molds, and die-casting molds, is the primary application for the slow wire cutting processing technique. The processing of a large number of precision holes, such as those found in die-casting molds, requires the use of the key technology of slow wire cutting. Insert holes, ejection pin holes, inclined top holes, cavity corners, and slider processing are some of the common applications that are utilized in the manufacturing of die-casting molds. A high level of precision can be achieved through the use of the slow wire processing method. The processing accuracy of high-end machine tools can be reduced to less than 3 micrometers, and the surface roughness can be reduced to 0. 05 micrometers. At the moment, it is possible to realize automatic threading and cutting of electrode wires with diameters ranging from 0. 02 die casting defects causes and solutions to 0. 03mm, and the cutting efficiency in practice can reach approximately 200mm2/min.

The Electrical Discharge Machining (EDM) technique is useful for the processing of complicated parts with features such as precision small cavities, narrow slits, grooves, and corners.The EDM process is preferable to milling in situations in which it is difficult for the tool to reach complex surfaces, situations in which deep cutting is required, and situations in which the aspect ratio is particularly high.Milling electrode re-discharge has the potential to improve the success rate when it comes to the processing of high-tech parts.Electrical discharge machining is a more appropriate option when compared to the high and expensive tool costs.In addition, electrical discharge machining (EDM) is utilized to produce a spark-marked surface in those areas where EDM finishing is required.
Today, as a result of the rapid advancement of high-speed milling, the development space for EDM has been constrained to some degree.At the same time, increased technological advancements have also been made in EDM as a result of high-speed milling.

A grinder is a piece of precision equipment that is used to finish the surface of die casting mold parts, particularly workpieces that have been hardened. For the most part, surface grinders, universal internal and external cylindrical grinders, and jig grinders are the types of grinders that are utilized in the processing of die-casting molds. Die-casting mold parts of a smaller size typically require the use of a small flat grinder for the grinding process. The processing of larger size formwork frequently calls for the utilization of larger water grinders. Increasing the linear speed of surface grinder grinding wheels and the movement of worktables has become a prevalent practice in modern times and has become a common trend. The movement speed has been significantly increased as a direct result of the implementation of cutting-edge functional component technologies. These technologies include linear guide rails, linear motors, and static pressure screws, among others. In addition to that, it has also undergone consistent development for the better. The technology for dressing grinding wheels. In order to achieve ultra-precision grinding, the minimum vertical feed that can be achieved by the grinding head is 0. 1 microns, and the processing accuracy can CNC machining parts be controlled to be within 1 micron.

In mold workshops, CNC lathes are another type of processing equipment that is frequently used. All rotary body parts are included in its processing scope. The rapid development of CNC technology has made it possible to easily create rotary bodies with complex shapes through the use of programming. Additionally, machine tools now have the ability to automatically change tools, which has significantly improved the effectiveness of production. CNC lathes are becoming increasingly perfect in terms of both their processing accuracy and their manufacturing technology. In fact, there is a trend emerging that sees lathes being used rather than grinding machines.

High-precision measurement equipment plays an important role in a variety of stages of the mold design process, including the digital surveying and mapping that is done in the early stages, the measurement of the mold processing process, the measurement of the mold acceptance, and the measurement of the mold repair that comes later. There are primarily three types of measuring machines: portable articulated arm measuring machines, image measuring machines, and coordinate measuring machines. All of these are suitable for on-site measurement of large molds and other similar objects. In order to successfully manufacture a die-cast mold part, frequently multiple processes are required.

It takes a significant amount of time because the parts have to be continuously clamped and calibrated throughout this process. In addition, the machine tools are not being used, and the capabilities of the costly equipment are not being utilized to their full potential. Shorter production cycles are becoming more common in the manufacturing industry as a result of the increasingly cutthroat competition in this sector. In order to achieve unified reference exchange for milling, turning, measuring, EDM, and other processes, fixture manufacturers from other countries have adopted a reference system that is both reliable and accurate. It only takes about a minute to quickly complete clamping and installing electrodes on the machine tool, which is a task that can be done in this amount of time. The alignment and repeat positioning accuracy are both within 3 micrometers, which helps to reduce the amount of time spent setting up the machine tool and significantly increases the amount of time it can spend actually operating.

This has been shown to be a necessary requirement for the production of modern goods. When a rapid clamping and positioning system is utilized, the structural components necessary for automation are already in place. In order to form an automation unit as part of the mold processing center, the advanced mold workshop has been outfitted with robots and software that is adaptable for system management. The more advanced international manufacturers have started to transition from being simple providers of equipment to becoming providers of complete solutions.
