Deep Drawing Press

In the metal forming industry, the term "hydraulic deep drawing machine" refers to a specific type of drawing machine, which is one of the most commonly used presses in the deep drawing production industry today. Many manufacturers use to produce various industrial items as well as daily-use items. Regarding industrial applications, many are used in furniture, sports, consumer electronics and household appliances.
 
The size of the die is a key feature, which will determine the corresponding size of the press to be used. If the manufacturer really needs a product whose size is very different from the ordinary product specifications, the scales of its hydraulic deep drawing machine will be different. To be precise, hydraulic deep drawing presses have been divided into conventional and unconventional deep drawing processes based on their working mechanism. The main goal of the unconventional deep drawing process is to expand the original formability limit of the workpiece. Some unconventional deep processing processes include Aqua drawing process, hydro mechanical deep drawing process, hydro forming process, etc. All these unconventional deep drawing operations are designed by the press manufacturer for specific purposes, and are subject to a great variety of changes.

Critical Features of Deep Drawing

If this type of machine is compared with other presses, such as trial presses and ordinary production presses, the mechanical force of the hydraulic deep drawing machine will be stronger. Because the main task of this kind of machines is to perform deep drawing on the work pieces no matter of its material essences. In addition, since the deep drawing press is responsible for real, mass production of products, the mechanical strength is not limited to force, but also to many other specifications. For example, many hydraulic deep drawing machines are equipped with heavy-duty emulsions, phosphates, white lead, and wax films to reduce the great force of friction that is caused during operation. Manufacturers of hydraulic deep drawing press machines may use materials with high tensile strength to obtain higher accuracy and better adjust the parallelism of the pressure plate when the die cuts the workpiece under high pressure. Besides, modern hydraulic deep drawing machines are also equipped with many safety devices to ensure the safety of the dies and on-site operators. By providing more comprehensive protection for on-site operators and die objects, the manufacturing of products is in a better condition, and is expected to bring better results to suppliers and industrial users in the market.
                                                                                        
Moreover, many hydraulic deep drawing press machines are designed to have distinctive characteristics, especially in the rigid drawing stage. Because the punch that causes one end to cut is necessary to damage the other side of the die part. Contrary to hydraulic deep drawing presses, die/mold spotting presses are specifically designed for mold and die spotting applications. If they are applied to die spotting, their modifications and related settings will be different from those applied to the conditions. The deep drawing operation as the focus of the mold is trial production, while the deep drawing takes mass production as the main task. Experienced onsite workers know how to tilt the plate and make the settings for the target forming task.

 

Deep Drawing & Die Spotting

In many industrial forming processes, it is important to inspect molds before sending them to mass production lines. During the whole process, die spotting is a step to check whether the spot management is well and calibrated. As one of the most commonly used presses in the industry, die spotting presses are used by many manufacturers to produce various molds and dies, which are mainly used in automobiles, consumer electronics and household appliances. The sizes of the die spotting press depend on the corresponding size of the die or mold that to be spotted. Therefore, in general, if manufacturers require items that are very different in size from ordinary products, then the scale of their die spotting machines will be different. Compared with other presses such as try out press and ordinary production press, the mechanical force of a die spotting press would be much lesser. Because the main task of the compression molding machine is to check whether the contact points between the lower and upper mold/ die parts are appropriate or not.  
 
Moreover, since the die spotting press is not responsible for the actual production of goods, the mechanical differences are not confined to force, but also to many other specifications. For example, many die spotting presses are equipped with invert cast design (mostly 180 degrees), which can be inspected in detail during the process. Whether the die or mold material is metal, plastic or other synthetic materials, different variables require different inspection methods. Therefore, the development of trial die spotting presses aims to provide a fully-fledged die/mold press accuracy detection capability. Some die spotting press suppliers also provide an optional wax trail system for users to check the closing accuracy to meet the operator's requirements.

 

Forming Machineries in the Future

As agility and intelligence are the two main goals pursued by most machine tool manufacturers due to their customer demands, it is now widely seen that many large machine tool units are equipped with intelligent manufacturing elements, such as IT chips and other related technology. These efforts are to ensure a better manufacturing procedure, which can bring advanced pressing quality to industrial users and end product consumers.
