How to fix industrial aluminum mold? In short, it is: correct analysis and judgment, and reasonable adjustment of metal flow.

The main work of the modification of industrial aluminum extrusion mold is to adjust the metal flow distribution ratio, adjust the contact friction coefficient, hinder interception and other methods, and adjust the length of the mold hole working belt to change the metal flow speed out of the mold hole. The metal is evenly flowed out of the die hole to produce a qualified extruded product. Therefore, the mold maintenance personnel of aluminum profile manufacturers must master all relevant inspection techniques, and then they can correctly analyze and judge the cause of product defects to perform effective mold correction.

The proportion of metal supply is mainly determined by the mold designer and manufacturer. If the designer's distribution is unreasonable, the flow velocity of each part of the profile will be uneven, which will bring some difficulties to mold maintenance. In most industrial aluminum molds, although the amount of metal has been determined, the frictional resistance between the metal and the mold can be changed. So as to achieve the purpose of regulating metal flow.

The friction between the metal and the mold includes three parts: the contact friction between the metal and the mold surface, the contact friction between the mold hole processing belt, and the friction between the metal and the metal. Improving the friction conditions between the metal and the mold surface can play a role in adjusting the metal flow rate. Changing the amount of metal dispensed, the friction conditions, the length of the work belt and the extrusion speed can all adjust the speed of the metal leaving the die hole. Although there are many factors that can affect the speed of metal flowing out of the mold hole, they can be summarized into two basic factors: 1. Is the metal distribution velocity suitable for each part of the cross section of industrial aluminum profiles? That is, whether the ratio of the cross-sectional area of each part of the profile to the metal flow of the corresponding supply part is equal; b. When metal flows, the amount of frictional resistance, when the amount of metal supplied to a certain part of the industrial aluminum profile is larger, the frictional resistance will be smaller, and the flow rate of the mold hole in the part will be higher. Fast and vice versa.
