High pressure
die casting is a process that helps in making some components like toy parts,
blocks of engine, levers, gears, bushings, parts used in automotive, medical
equipment, aerospace etc. If you are involved in any manufacturing or using any
of these products, then there are certain things related to die casting that
you should be aware of. Pressure die casting melts a metal and forces it into
steel dies. At the time of hardening, the metal can be moulded into any desired
shape that can fit into the part it is made for.
On interesting
aspect is that it eliminates the processes like welding and hence makes the
part without any joints. It gives a superior and accurate dimension, smoother
surfaces, and higher quantity of products / parts. Machining is only required
for removing holes and flashes around the edges. It enables inserts to be
cast-in, tensile strength ranging to 60 ksi, casting metal with low fluidity
etc. While one of the very common disadvantages is the high investment, but
once a pressure die casting tool is made, the cost of manufacturing parts in
huge volume will come down. The die casting machines are provided by
manufacturers that can be customized as per the users’ requirements.
The use of right
lubricant is important for safety of the process. You should use water – based
lubricant so that it can be treated to remove the minerals. The minerals, if
not removed, can damage the surface and cause discontinuities. Although, the
oil based lubricants can be easier to apply but it builds up carbon on the
cavity walls of the moulds.
