During extrusion production, a defect commonly referred to as 'tail shrinkage' may appear in the semi-finished parts of profiles and bars after cutting the head and tail and checking with alkaline etching. The mechanical properties of profiles and bars conta...

What is a trial mold: 1. Extend the processing running time to stabilize the temperature of the molten glue and hydraulic oil. 2. Adjust the machine settings according to whether the finished product dimensions are too large or too small. If the shrinkage ...

The manufacturing of aluminum extrusion dies is also one of the key factors determining their quality and service life. Because aluminum extrusion dies have a series of characteristics, they impose certain special requirements on the die-making technology fo...

Process Control Due to the most significant characteristic of 6082 aluminum alloy being its content of refractory metal Mn, the appropriate presence of Mn can easily lead to intra-granular segregation and reduced solid-liquid region plasticity, resulting in...

Overview and Characteristics of 6-Series Aluminum Alloys:6-series aluminum alloys are aluminum alloys primarily alloyed with magnesium and silicon, with the Mg2Si phase as the strengthening phase. They belong to heat-treatable, strength-enhancing aluminum al...

1. Stretching must only be carried out on aluminum alloy profiles after they have cooled to below 50°C before being moved onto the stretching frame. If the temperature is too high during stretching, it can burn operators and damage the burrs. Moreover, i...

Characteristics of oil stains on aluminum profiles surface:If oil stains on aluminum profiles are not cleaned before aging, watermarks will appear on the aluminum surface after aging. After oxidation, dark spots with a certain depth will form. Causes of oil...

(1) Aluminum electrocoating bath equipment. Aluminum profile electrocoating baths are mostly designed as rectangular tanks, and the size of the base depends on the dimensions of the fixtures used for hanging. The tank body is made of 4–6mm steel plate ...

1. During the trial of aluminum alloy profile extrusion dies and the aluminum extrusion process, attention should be focused on the following aspects: A. Determining the temperature of the die and rod before extruding aluminum alloy profiles, ensuring it me...

6-series aluminum plates are aluminum-magnesium-silicon alloys, with representative grades including 6061, 6063, and 6082. Unlike the other seven series of aluminum plates, 6-series plates are mainly in T temper, with the most common being T5 and T6. With on...
