Ask Master: at present domestic industry deep aluminum extrusion production line of domestic manufacturers are also many, but the price is still the production line and abroad have obvious difference, then foreign production lines in what ways do better? Thank you
The temperature of the extrusion bar and the temperature of the die and the temperature control of the outlet are more accurate. Technically speaking, after all, foreign development is much better than domestic time, from casting alloy ratio to extrusion temperature control, there is still a certain gap between time control.
The surface treatment process is also lagging behind. However, the gap is still shrinking, and many manufacturers are investing in R & D funds to develop new processes. Some of the products produced can also be compared with foreign production lines.
On the equipment, the extrusion line of Germany and Japan is more automatic, and the on-line quenching is the setting program for automatic operation.
