Feature：The lock cylinder is the heart part of the door lock. Even if it is a smart lock, the safety level of the lock cylinder is still very important. Its main function is to transfer the torsion from the head, so as to drive other parts to open and lock. The head structures of padlocks, drawer locks, door locks and bicycle locks are different, and the ways of transmitting torsion are different, but the functions are the same.
Advantage: MIM is the best way to make a lock cylinder. Not only MIM can make various kinds of complex shape parts, but also it can meet the requirements of the size precision. If the tolerance has high demand, after MIM, we need to do extra CNC process. As to the surface, most lock parts have no further requirement, because stainless steel can resist the rust. Its surface is bright enough.
MIM technology can make various kinds of metal parts. If your part is made of stainless steel, steel, iron and the shape is complex, MIM is the best choice. If you want to make metal components by MIM, you need to send us the parts drawings, including PDF and 3D files in which, we can see the shape, sizes, tolerance and other requirements such as surface treatment, hardness(HRC). Also, we need to know the quantity for the part. Because to make MIM items, the mold is important. To make a mold is around 3000--5500USD that based on the shape, so if the customer have several parts to produce, we suggest to put them in one mold to save cost.
