The main problem associated with a casting process is that of porosity. The two types of porosity and their causes are discussed in this article along with techniques that can be used to alleviate porosity problems.
Mechanical fastening techniques such as adhesive bonding and evolved riveting options have become more popular since the automotive industry started using alternative construction materials to steel.
The basic principle behind all welding processes is to produce a molten pool in the locality of the joint being formed and to add a filler material (if required) as the materials from either side of the joint run into...
There are 2 types of isostatic pressing processes:Hot isostatic pressing (HIP) & Cold isostatic pressing (CIP. Both processes are expensive from an operating cost perspective but HIP should be considered a very...
Pressing and sintering is a process choice used when there are fairly exacting requirements that have to be met as dictated by the design specifications laid down.
The extrusion process applies to a variety of processes that involve confining a material in a container and applying a force to push the material through an orifice to produce a required shape.
Electrochemical Machining involves removal of material from a workpiece using electrolysis. The material for this process to work has to be electrically conductive.
Single point cutting using standard tools and equipment is a good option for the production of small batches and 1 off items such as prototypes.
Squeeze casting uses an accurately measured quantity of molten metal which is poured into a mould using a launder.
What you need to know about 'gravity die casting' simply explained and illustrated in text and video.
The selection of a manufacturing process is done very much on the basis of a manufacturer choosing the process that best suits his needs. Consideration must be given to a number of factors before deciding.
