Deep drawing is a sheet metal forming process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch. It is thus a shape transformation process with material retention. The flange region (sheet metal in the die shoulder area) experiences a radial drawing stress and a [...]
Piercing is a shearing process where a punch and die are used to create a hole in sheet metal or a plate. The process and machinery are usually the same as that used in blanking, except that the piece being punched out is scrap in the piercing process. […]
Metalworking is the process of working with metals to create individual parts, assemblies, or large scale structures. […]
It can take some time to create jewellery using Repoussé and chasing, although with practice, complex and delicate pieces can be made which would be virtually impossible to complete using any other method. It takes a lot of time due to the repetition of a number of time-consuming stages: the preparation of a sheet by [...]
The techniques of repoussé date from Antiquity and have been used widely with gold and silver for fine detailed work and with copper, tin, and bronze for larger sculptures. Among the most famous classical pieces using this technique are the bronze Greek armour plates from the 3rd century BC. […]
Repoussé (French pronunciation: [ʀəpuse] or repoussage [ʀəpusaʒ] is a metalworking technique in which a malleable metal is ornamented or shaped by hammering from the reverse side. […]
Blanking is a shearing process where a punch and die are used to create a blank from sheet metal or a plate. The blank is workpiece ejected from the starting stock. The process and machinery are usually the same as that used in piercing, except that the piece being punched out in the piercing process [...]
There are three basic types of bending on a press brake, each is defined by the relationship of the end tool position to the thickness of the material. These three are Air Bending, Bottoming and Coining. The configuration of the tools for these three types of bending are nearly identical. […]
Competitiveness and price pressure in the injection molding industry has influenced many OEMs, molders and mold manufacturers to look for new ways to survive and thrive in their regional and global markets. […]
Step back for a moment and think about the voices we’ve been listening to over the past 10 years—what do you remember? Separate voices.Special interests have called for special considerations. Specific industries and associations and lobbyists represented their own interests—often with the best of intentions—that resulted in fractured, disjointed, poorly managed tactics that led to [...]
