Tip: Defects in aluminum profiles are a factor leading to waste. A small defect on an aluminum profile can ruin the entire fixed-length cut aluminum profile. Since aluminum profiles have a high added value, extrusion manufacturers should make every effort to minimize defects in aluminum profiles.
1. Non-extrusion cycle time – Assuming the production efficiency of an aluminum profile extrusion machine is 30 aluminum rods per hour, and each non-extrusion cycle saves 10 seconds, then 2 hours of extrusion time can be added each day. Two hours means more than 8% increase in output, which is equivalent to reducing conversion costs by 8% per kilogram of profile.
2. Downtime – The losses caused by downtime are huge, not to mention the lost production capacity during downtime due to no output.
3. Extrusion Speed – The production efficiency brought by high-tech aluminum profiles molds should be carefully considered. If the purchased aluminum profile molds can achieve faster extrusion speeds compared to the molds manufactured by the extrusion company itself, then an order of moderate quantity can offset the additional costs incurred from purchasing the molds.
4. By using a porous mold, the extrusion speed can be increased by 200% (for a 2-hole mold) or even 300% (for a 3-hole mold), resulting in higher economic benefits.
Using a modern aluminum profile traction machine, one of the greatest advantages is that when the aluminum profile reaches the correct extrusion length, the traction machine has the function to control the extruder to stop extruding. This is similar to a non-extrusion cycle, but because the extruded aluminum profile is exactly the required length, no extrusion time is wasted. Therefore, more costs can be saved, as it reduces waste while also saving the steps of conveying and recycling the already extruded waste.
After the aluminum profile is extruded from the extruder, the most important goal is to improve output and deliverable rate by reducing waste, so that more products can be sent to customers. Any waste generated after extrusion will be very costly, so subsequent processes should minimize waste generation as much as possible. To reduce waste to a minimum, cutting must be done at the stop marks.
