Post Process
——————————————————————————
Cosmetic Base Post Process information are Subject to Material & Requirements
CNC
Post Process
Some complex shape product need CNC/ Machining during the post process,this could be addition but it is not important that every part must need it. This depend on part's requirements.
PVD
Possible to get the different PVD color such as White,Black,Golden,Brown,Green,Blue ect……
Surface Finish
MIM product are good to get the required surface finish such as hair line surface finish,brush finish,sand blast mirror surface finish ect
Plating
MIM material can be readily plated or surface treated with standard process used on wrought material with no need for special surface preparation.Examples of some plating and surface treatments offered are: electrolysis nickel,chrome,zinc,chromatic,nickel teflon,black oxide and passivisation.
Process Description
——————————————————————————
Metal powder of fine partical size is mixed with thermoplastic polymer to form a mixture of ingredients konwn as feedstock. The feedstock made into pellets and fed into the moulding machine.
The feedstock is heated to melt the plastic and molded to the desired shape. The moulded parts is known as green part.
The binder is removed thermally by heating to around 400 degree centigrade from the green part,by a debinding process. The debound parts called as brown parts and is brittle and porous.
The brown parts is heated to more than 1200 degree centigrade,in the finale sintering process allowing the part into a dense solid with the elimination of pores. The sintered density is wimilar to a casting at about 98% of theoretical.
FAQ
Q: What is MIM technology ? A: MIM (Metal Injection Molding) is a manufacturing technology that combines the shape making complexity of Plastic Injection Molding with the material flexibility of Powder Metallurgy.
