FAQ

processing cd grain screw material what are the requirements?

First of all, the requirements of the metal surface: 302.304.410 stainless steel screws are more suitable for processing CD patterns, while other materials are not so good;

Generally, if the plasticity is medium and the plasticity is too low, brittle cracks will expand during etching. If the plasticity is too high, adhesive tape will occur. Just like the adhesive knife in the face, the CD pattern will be processed only after the microstructure and properties of the material are changed through the vacuum heat treatment process.

Note: Because the general stainless steel screws are not magnetic, it is not easy to assemble; and the 410 is magnetic, the screw assembly efficiency is higher than the 302 stainless steel.

how to choose cd pattern screw wire?
cd pattern screws are widely used. In different fields of products, such as: electronics, electrical appliances, mechanical equipment products are required to use the CD pattern screw, then the CD pattern screw wire should be how to choose.

1. Iron cd-pattern screws are actually produced using iron wire. The market is generally wire cd-pattern screws, they are through the electroplating of white zinc, zinc, nickel and other production of these white wire.

2, stainless steel cd pattern screw is the use of stainless steel wire production. The production of stainless steel cd-grain screws does not require electroplating. Generally, it only needs to be cleaned to make the stainless steel cd-grain screws bright. However, some customers also need to electroplate or electroplate different colors of CD pattern screws for stainless steel CD pattern screws.

CD pattern screws commonly used materials are carbon steel, stainless steel, iron, low alloy steel and non-ferrous metals. However, in some cases, fastener materials need to meet the conditions of severe corrosion or high strength, there are a lot of stainless steel and ultra-high strength stainless steel came into being.
