Common problems in the production of aluminum profiles
Problem: dragging black, slag inclusion, adsorption granules, welds, low yield
Production process control:
1. Before heating the aluminum rod, use a duct to blow off the dust on the aluminum rod.
2. The remaining thickness should be enough. If the thickness is too thin, the dead zone of the bar will be caught in the end of the profile, causing dragging and slag;
3. The extrusion speed should be effectively controlled, especially the end should be decelerated to prevent turbulence from being caught in the skin impurities; 4. Every production period (at least 30 bars) should be cleaned;
