What Is Copper Impregnated Graphite?
There have been many theories written on how copper graphite is created, many of which are completely untrue. […]
New equipments help first-rate mold company
first-rate mold company was started in 1989 by steven “We saw an opportunity in the small dimensional tools market and relied on our reputation and broad understanding of moldmaking to move into this niche,” says steven. “Small details can severely affect the quality of a finished part in complex moldmaking,” notes steven. “By providing injection [...]
What is Metalworking?
Metalworking is the process of working with metals to create individual parts, assemblies, or large scale structures. […]
The method of Repoussé and chasing
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 history of Repoussé and chasing
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. […]
Introduction to Repoussé and chasing
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. […]
Introduction to Drawing and it’s process
Drawing is a metalworking process which uses tensile forces to stretch metal. It is broken up into two types: sheet metal drawing and wire, bar, and tube drawing. The specific definition for sheet metal drawing is that it involves plastic deformation over a curved axis. For wire, bar, and, tube drawing the starting stock is [...]
Introduction to Blanking– metalworking
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 [...]
How many types of bending on a press brake
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. […]
What is bending? — metalworking
Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal. Commonly used equipment include box and pan brakes, brake presses, and other specialized machine presses. Typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork. [...]
