Press machine was developed in the very age in the human history in the bronze age that used to be of weaponry processing equipment and has been evolved for thousands of years. As one of the most commonly used press machines in the industry, die spotting press is used nowadays by many manufacturers in the production of a variety of molds and dies that are mostly applied to automotive, consumer electronics, and household appliances. The size of the die spotting presses dependents on the corresponding sizes of dies or molds that to be spotted.
Therefore, generally speaking, if manufacturers do require an item that whose size is largely different from their ordinary products, the scale of their die spotting machines would be different. Compared with other press machines such as try out press and ordinary production press, the mechanical force of a die spotting press would be much lesser because the primary task of a die spotting machine is to inspect if the contact points and surfaces between the lower and upper mold/ die parts are appropriate or not.
Furthermore, since die spotting press machines are not responsible for real production of goods, the mechanical differences are not only confined to the forces but also to many other specifications. For instance, many die spotting press machines are equipped with invert cast design (mostly 180 degree) that enables detail inspection in the process. Whether the die or mold materials are of metal, plastics, or other synthetic materials, different variables require different kind of methods of inspection and testing.
Therefore, the development for trial die spotting press machines aims to offer completely full-fledged capability for die/ mold accuracy spotting. Some die spotting press suppliers also offer optional wax trail system for users to inspect closing accuracy in order to meet the operators’ requirements and rigorous demands for their processing procedure.
Producers of die spotting presses may use high tensile rods to achieve higher accuracy and to make the machines with better platen parallelism adjustment when either the mold or die is closed under great pressure. Besides, modern die spotting machines are installed with many safety devices, such as pneumatic mechanical locks for the upper table, four-mold clamping cylinders for stability, anti-dropping devices with suspension type to ensure the safety of trial molds and dies. The protection of machinery is also a focus as well as dies and molds.
More protection procedures for both onsite operators and molds and dies, the manufacturing of molds and dies are thus under better condition and circumstances, promising preferable results and output quality to suppliers and customers with different conditions.
Spotting press machines are designed with acute characteristics especially on the stopping and guiding positions, because it is necessary that the punches that cause cutting of one end hurt the corresponding other side of the die parts. On the contrary, molds are not like dies, so molds are with less acute in guiding, while the columns on the injection machines are exploited for these purposes and goals.
For the sake, even a die/ mold spotting press machine is designed for both mold and die spotting usages, if it is applied to die spotting, the modification and relevant settings would be much different to the condition that it is applied to mold spotting. Experienced onsite workers know how to tilt the cast and make the setting suitable for the order demands.
It is an essential comparison to talk about deep drawing when people are talking about die spotting since normally die spotting is a frontier step of deep drawing. Essentially, hydraulic deep drawing press is one of the most commonly used press machines in the industry nowadays. It is used by any manufacturers in the manufacturing of a variety of industrial objects as well as items used in daily basis. Regarding the industrial applications, many deep drawing press machines are applied to furniture, sports, consumer electronics, and household appliances. The size of the die determines the corresponding sizes of the press machines to be used. As a result, usually if manufacturers do require an item whose size is largely different from ordinary products, the scales of their hydraulic deep drawing machines would be different.
Deep drawing nowadays has been classified into conventional and unconventional deep drawing processes. The main purpose of unconventional deep drawing process is to expand the original formability limits of the work piece. Some of the unconventional processes include Aqua-drawing process, hydro-mechanical deep drawing, Hydro-forming process, etc. After die spot, users will check all the pressing variables and then set their following deep drawing pressing steps for massive production line.
