The Cause of the Cause of Tearing and Elimination of the Surface of the Aluminum Profile-WJW Aluminum Supplier Aluminum

The disadvantages of the nominal cracks of aluminum profiles: The nominal of aluminum profiles shows the longitudinal sparkling repetitive intervals, and the significant direct disconnects are disconnected. The most widely used non -ferrous metal structure materials in the aluminum alloy profile industry, in aviation, aerospace, automobiles, machinery manufacturing, ships, buildings, decoration.

The cause of the nominal cracks of aluminum profiles:

(1) Excessive squeezing coefficients of aluminum profile, excessive squeezing temperature (stick, tube, mold three temperature), the squeezing speed is too fast;

(2) The pressure of squeeze is unstable, high and low, or the speed difference between the speed adjustment of multiple gears is obvious.

(3) When the aluminum alloy profile is squeezed out, the head end is pressed (stamping) too fast, the end speed of the tail end or does not decelerate, and the aluminum is soaked in a large amount of aluminum;

(4) The quality of the stick is poor. Burid (V3 aluminum) is too thin;

(5) The design and manufacturing of squeezing mold flow rate is not fair. The most widely used non -ferrous metal structure materials in the aluminum alloy profile industry, in aviation, aerospace, automobiles, machinery manufacturing, ships, buildings, decoration.

Method of the nominal crack elimination of aluminum profiles:

(1) The profile with a large squeezing factor may be placed in a small machine, adopting a suitable squeezing ratio; in addition, the three temperatures must be held in strict accordance with the production process request, and the appropriate squeezing speed should be adopted;

(2) Concentration of the operator's energy, stable speed regulation, and unable to be high or low. Manual operation and cooperation when changing gear changes;

(3) The front end of the seal of the aluminum material is the death area or the V3 volume (aluminum rod surface) aluminum. There are many impurities, poor quality, and insufficient viscosity.

(4) The name of the aluminum stick should be delicate and clean, and the internal tissue must meet the standards.

(5) Squeezing mold designers should design and manufacture the same -goal mold with a velocity. The most widely used non -ferrous metal structure materials in the aluminum alloy profile industry, in aviation, aerospace, automobiles, machinery manufacturing, ships, buildings, decoration.
