petroleum perforating housing blank for oil and gas from forging supplier

It is used for petroleum drilling. Material is S20 which is a  high quality carbon steel. The product we are producing which diameter from 30 to 60 which using cold forging (cold extrusion) process.

Cold extrusion features a massive forming process to produce both hollow and solid blanks in a multistage production process (multistage pressing).Presses with a very high closing force carry out cold forming of the material under a high pressure until the desired shape is achieved.

The material is extruded there by application of a high pressure. An upper die presses the blank through a forming and cross-section-reduced die orifice - the mold.

Longkou Dayuan, is able to make products with complicated geometry and a high forming degree.

Advantages of cold extrusion process:

1. high dimensional stability
2. excellent surface finish
3. continuous fiber flow line thanks to forming
4. efficient process for mass production
