How to distinguish the thimble and the silk copper in the plastic mold structure
Jan 24, 2018

    

        The thimble and the cylinder are used as the thimble assembly, which is one of the plastic mold parts, and the thimble is the thimble of the cylinder needle component.The thimble is used to make a metal rod that is made from the top of the glue.The product is constantly pushed out in the high speed mold, and the telescopic movement is used for abrasion or machining.

The thimble is usually made of stronger metal than the cylinder, such as SKH51, with a hardness of 58-60hrc.The cylinder needle made of high quality high speed steel has a beautiful metallic luster.The thimble production process is similar to thimble.The structure size of the thimble cylinder is very different from that of the thimble, and the size of the large head usually has an irregular size.

It is usually necessary to spray anti-rust agent to prevent rust when the thimble is produced. In the process of use, if the mold is idle for a long time, it should also be careful to prevent rust.The tube needle nitride treatment has wear-resisting characteristic, durable hot make die steel, can withstand 1200 degree above high temperature
