How to reduce the occurrence of defects in precision aluminum tubes

[China Aluminum Network] Precision aluminum pipe defects are one of the factors that cause waste. A small defect on a precision aluminum pipe will destroy the entire precision-saw aluminum pipe. Due to the high added value of precision aluminum tubes, extrusion manufacturers should make every effort to reduce the occurrence of defects in precision aluminum tubes. Non-squeeze cycle time - Assuming that precision aluminum tube extruders produce 30 aluminum rods per hour and each non-squeeze cycle saves 10 seconds, then you can increase the extrusion time by 2 hours per day, meaning 2 hours. More than 8% of the output, which is equivalent to a 8% reduction in conversion costs per kilogram of profiles. Downtime (outage) - Loss due to downtime is huge (in our example we have a shutdown loss of $48.00 per minute), not to mention lost capacity during the downtime because of no output. Extrusion speed - The production efficiency of the purchased high-tech precision aluminum tube mold should be carefully considered. If you purchase a precision aluminum tube mold that can achieve faster extrusion speeds than the extrusion mold itself, then a moderate amount of orders can make up for the additional cost of buying the mold. For example, assume that the normal cost is 2,860.00 yuan/hour, because the additional cost incurred for purchasing high-tech molds is 10,000.00 yuan. As long as the extrusion speed increases by 50% and the basic production efficiency reaches 800 kg/hour, then an order of less than 10 tons is obtained. It can make up for the extra costs of using expensive molds. With the use of multi-hole molds, the extrusion speed can be increased by 200% (2-hole molds) or even 300% (3-hole molds), resulting in higher economic benefits. One of the great advantages of using modern precision aluminum tube haulers is that the haul-off machine has the function of controlling the extruding machine to stop extruding when the precision aluminum tube reaches the correct extrusion length. This is similar to the non-extrusion cycle, but since the extruded precision aluminum tube is exactly the required length, no wastage of the extrusion time is caused. As a result, more cost savings can be realized, as the waste reduction process also saves the transportation and re-use of the extracted waste. After the precision aluminum tube is extruded from the extruder, the more important goal is to increase the output and the rate of shipment by reducing waste, and send more products to customers. Any waste that is generated after extrusion will be very costly, so waste should be minimized in subsequent processes. To reduce the waste to a small extent, it must be sawed at the stop mark (stop mark refers to the trace left by the mold during the non-extrusion cycle). There are only two technologies that can achieve sawing at the stop mark - fly saw cutting and dual length systems. Flying saw cutting technology refers to sawing in the extrusion process. Using flying saw cutting technology, it is possible to cut the profile at the stop mark after the stop mark emerges from the extruder. The double-length system means that after the second profile has been extruded, it is cut between the front and the second profile in the non-extrusion cycle. Both technologies have their own advantages. The two-length system can provide air cooling for two squeeze cycles, which is very beneficial for building alloys. However, the flying saw cutting system has lower costs (equipment costs and plant space costs) and allows one-shot multi-cut mode operation without stopping the extruder. Precision aluminum tubes move on the extruder's conveyor system - any movement on the extruder's conveyor system can damage precision aluminum tubes. For example: The modern transmission system uses a tractor to place the precision aluminum tube directly in line with the head of the stretcher, so that it is not necessary to push and pull the precision aluminum tube on the belt table to make the aluminum material and the stretcher. The jaws are aligned. Therefore, the possibility of the profile being scratched can be reduced.
