The conventional approach to the processing of metal sheets primarily involves the utilization of molds for the purpose of cold stamping on a press. This method offers the many benefits of high production efficiency and is suitable for mass production. In many cases, the process of developing new molds for product formation is not only expensive but also risky, time-consuming, and lacks flexibility.

A flexible production technology that was developed in order to accommodate this trend is known as flexible mold technology. When it comes to the processing and manufacturing of parts of varying shapes die casting part design, the fundamental concept behind flexible mold technology is to make use of deformable structures or materials to either completely replace or partially replace traditional rigid molds. A growing number of people are becoming interested in this technology, which is a rapid manufacturing process. This article provides a summary and analysis of the most important technologies and development trends of flexible molds, based on the findings of research conducted both domestically and internationally. Method of forming rigid molds using multiple points

Traditional rigid molds are replaced by multi-point flexible mold technology, which is also known as reconfigurable discrete mold technology. This technology makes use of several basic bodies that are height-adjustable and are arranged in a regular pattern. The end faces of these basic bodies are responsible for forming a multi-point adjustable die casting part design envelope surface. A new type of stretch forming discrete mold that is capable of automatically adjusting the profile was designed and manufactured by the Massachusetts Institute of Technology (MIT), CyrilBath Company, and the Naval Research Laboratory between the years 1985 and 1991. In order to prevent the surface of the sheet from forming, it is required that its surface be covered with an elastic cushion layer before it is used.

2. Technology that utilizes a multi-point blank holder coupled with variable pressure deep drawing forming

During the past few years, the technology of multi-point blank holder variable pressure deep drawing forming has been utilized. At the moment, this discrete mold technology is capable of achieving moldless forming of sheet metal components. Additionally, it is simple to achieve CAD/CAE/CAM/CAT integration wire clamps as well as automation of sheet metal forming. The formation of a moldless factory is possible further development. The process of measuring the shape and repeatedly processing the parts until they meet the requirements for shape and accuracy. 

It is even more obvious that this benefit is present.) to take the place of the rigid punch or the concave mold as the medium at which force is transmitted during the forming process, and works in conjunction with anotherWhether it be a rigid concave mold or a convex mold, the plate is formed through the process of molding by the action of a force transmission medium. There are three primary categories that can be used to classify sheet soft mold forming. These categories are solid soft mold forming, semi-solid soft mold forming, and liquid (gas) soft mold forming. These categories are based on the variations in the physical properties of the force transmission medium. Rubber molding is the most common type of molding, and it is characterized by the utilization of elastic materials like polyurethane rubber as soft molds.

When it comes to solid medium pressure transmission forming in solid soft mold forming, solid particle pipe forming is a process that incorporates the use of solid particles rather than rigid punches (or elastomers, liquids) in order to create pipes. As a result of the fact that the pressure on the surface of the blank can be controlled during the forming process, it is possible to effectively prevent the tube blank from cracking in the thinning area. This is accomplished by controlling the sequence in which different parts undergo deformation. The formation of tubes that are difficult to deform, have a high strength, and have a low plasticity can therefore be accomplished through the use of this process. Manufacturing technology that is cutting edge. After the blank has been pressed into a super-elastic flexible pad by means of a pressure roller, the blank is then contained within the flexible pad wire clamps during the manufacturing process. In order to obtain profile bends with varying curvature radii, it is possible to adjust the pressing depth of the press roller as well as the horizontal displacement of the blank. Additionally, in order to achieve flexible forming of three-dimensional curved panel parts, a roll-shaped object that is bendable is utilized as a forming tool.

This is combined with multi-point shaping technology. In order to achieve efficient and continuous forming of three-dimensional curved parts, such as spherical parts, saddle parts, twisted parts, disc-shaped parts, cylindrical parts, and free-form surface parts, multi-point roll forming can be utilized. The fluidity of the liquid force-transmitting medium is high, and it is characterized by a uniform distribution of pressure. Additionally, the same pressure is applied to areas in the deformation zone that have larger and smaller deformations. The medium that it uses to transmit force is between liquid and solid, which gives it a set of characteristics that are unique to itself. When compared to solid elastic soft molding, the viscous medium is able to better form high pressure in the pressure chamber due to the better fluidity of semi-solid materials. Additionally, the viscous medium is able to fill small fillets and complex surfaces well, which allows it to avoid local molding. As a result of the phenomenon of insufficient pressure to fully adhere to the mold, the shape of the formed parts becomes more complicated. Additionally, in comparison to liquid water or oil, the requirements for sealing are reduced.
