Regulations, Standards, and Reasons for Scrapping Aluminum Factory Extrusion Dies

Aluminum Extrusion Die Scrapping Standards
Based on the company's articles of association, under a service-oriented management model, this standard is formulated to regulate the management of aluminum factory dies, improve die utilization efficiency, and ensure production.

There are many reasons for scrapping aluminum dies: Firstly, the working conditions of aluminum extrusion dies are extremely harsh, enduring severe friction and wear under high temperature and high pressure. According to on-site production statistics, the main forms of die failure are as follows: (1) friction and wear failure, accounting for 65%; (2) fatigue crack failure, accounting for 18%; (3) plastic deformation and collapse failure, accounting for 15%. The criteria for determining a failed die are that the extruded product cannot meet product quality standards and the die cannot be repaired. The service life of a die is generally described by the effective extrusion quantity.

1. Scrap Process: When a mold is found to be damaged or worn out after use and cannot be repaired, the mold maintenance personnel from the Manufacturing Department will fill out a mold scrap application form. The form will be reviewed by the company's Deputy General Manager and implemented after approval by the General Manager. The Technical Department will then apply for the production of a new replacement mold.

2. Scrap Standards: The standards for mold scrapping refer to relevant national regulations and the asset management procedures established by the company, as follows:

1) Technical and quality standards for scrapping

(1) The product has stopped accepting orders, and there is no use for products made from the mold.

(2) The mold has reached the end of its lifespan and is severely damaged, making repairs impossible.

(3) Due to design changes, the original product has been modified, and the mold cannot be changed or repurposed.

(4) The mold has cracks, and the surface roughness required for the product cannot meet the product process standards.

(5) The mold has a high defect rate, and more than three attempts at "countermeasure meetings" have been ineffective.

(6) The mold has multiple burn welds and frequently breaks, making it impossible to complete a full production shift.

(7) Major insert parts of the mold are cracked, and remanufacturing the inserts is uneconomical.

(8) Due to design or manufacturing reasons, the mold often sticks, has dimensional deviations, and operates inefficiently.

(9) Other factors have rendered the mold unusable.
