Single weight 108 tons, one-shot molding of EHA6918*208mm head

on March 26, 2022, EHA6918X208mm head for PTA mold of Sinopec (Yizheng) manufactured by Henan Shenzhou Seiko Manufacturing Co.
, Ltd.
(hereinafter referred to as Shenzhou Head), single weight 108T, material 16Mn forging, The overall stamping is successful, announcing that the extra-large and extra-thick head products have taken another milestone step in the overall stamping production
.

The biggest highlight of the successful production process of Shenzhou head in this project is the design innovation of the mold and the evolution of the way of debonding (after the overall stamping of the head, the separation method of the mold and the head)
.
First of all, the design of the mold focuses on "saving, efficient and innovative" to carry out the development of "one mold with multiple uses", breaking the current situation of long manufacturing time and large material consumption of traditional casting molds.
, The method of casting the mold shell is made.
The new method reduces the material consumption of the traditional casting mold with a single weight of 200 tons by 50%, which greatly reduces the manufacturing cost (the cost of the mold cost is 1 million yuan).
Die casting time; secondly, for the head after the overall stamping of this project, the separation method of the bottom parting was adopted.
Compared with the previous separation method of the upper parting, the time of stripping was increased from 3-5 minutes to multiple parts.
The one-time release within 1 minute, on the basis of improving efficiency, greatly improves the control of the link after the head is formed, and provides a reliable prerequisite for the production of the subsequent process of the head; finally, for large diameter, extra large , The overall stamping production of extra-thick head products not only changes the traditional split-head production method, but also greatly reduces the process preparation time in the head production process, especially the welding and assembly before and after traditional head forming.
, reducing costs for customers and ensuring the construction period requirements
.

The successful suppression of this project is another feat of Shenzhou head after the delivery of the project of Hengli Petrochemical (Huizhou) PTA mold EHA6619X203mm head, single weight 90T, material SA516-70N, and it is another domestic stamping forming head.
The display and innovation of technical capabilities, while breaking through its original heights such as diameter, thickness, and weight, also marks a new leap in the development strategy of "internationalization, high-end, and special materials".
It has injected a new chapter into the future goals and dreams of Shenzhou Head Equipment World
