Defects in
precision aluminium tubes are a contributing factor to scrap. A small defect in the
precise aluminium tube will result in the scrap of a
precise aluminium tube sawn with a fixed length. Due to the high added value of
precision aluminum tubes, extrusion manufacturers should try their best to reduce the defects of
precision aluminum tubes. Non-extrusion Cycle Time - Assuming that the production efficiency of the precision aluminium tube extruder is 30 aluminium bars per hour and 10 seconds is saved per non-extrusion cycle, two hours of extrusion time per day can be increased, which means more than 8% of production, equivalent to an 8% reduction in conversion costs per kilogram of profiles. Downtime (interruption) - Losses due to downtime (48.00 yuan per minute in our example) are enormous, not to mention lost capacity due to no output during downtime. The production efficiency of high speed
precision aluminum tube mold purchased by extrusion speed should be seriously considered. If the
precision aluminum tube mold purchased can achieve faster extrusion speed than the mold manufactured by the extruder itself, a moderate order can compensate for the additional cost of purchasing the mold. For example, assuming that the normal cost is 2,860.00 yuan per hour, the extra cost of purchasing high-tech molds is 10,000.00 yuan. If the extrusion speed increases by 50% and the basic production efficiency reaches 800 kg/hour, an order of less than 10 tons can compensate for the extra cost of using expensive molds. .
With a multi-hole die, the extrusion speed can be increased by 200% (2-hole die) or even 300% (3-hole die), resulting in higher economic benefits. One of the greatest advantages of using modern
precision aluminum tube tractors is that the tractor can control the extrusion machine to stop when the
precise aluminum tube reaches the correct extrusion length. This is similar to the non-extrusion cycle, but because the extruded
precision aluminum tube is exactly the required length, there is no waste of extrusion time. Therefore, more cost can be saved because the process of conveying and recycling extruded waste can be saved while reducing waste. The most important goal of
extruding precision aluminium tubes from extruders is to increase production and deliverability by reducing scrap and to distribute more products to customers. Any waste produced after extrusion will be very costly, so in the subsequent process as much as possible to reduce the production of waste. To minimize scrap, sawing must be done at the stop mark (stop mark is the mark left on the profile during the non-extrusion cycle).
