The different molds are responsible for the various cross-sectional shapes of aluminum profiles. When the aluminum extruder is in operation, the process of extruding the aluminum rod is critical. The quality of the extrusion process will directly affect the quality of the aluminum profile. So before the aluminum extrusion work, a trial mold will be carried out.
Whether it is custom profile or conventional profile extrusion, the trial mode is very important. So why do you want to test the mold? The main reasons are as follows:
1. In order to extend the processing and running time, the oil temperature of the hydraulic oil needs to be preheated to stabilize the melt temperature.
2. To adjust the operation of the aluminum extrusion press, aluminium profile products usually have a certain shrinkage rate. Refer to the larger and smaller values of the product size to adjust the aluminum profile extruder. If the value deviation is too large, the size of the gate can be adjusted to operate.
3. The size deviation of each cavity can be corrected. Suppose the size of the cavity and the door can be adjusted. In that case, you can modify it by adjusting the filling rate of the aluminum extruder or the temperature of the mold and checking the cavity's filling. Has the die speed kept up?
4. Check whether the position of the mold cavity or the model has moved, you can also check whether the filling rate is uniform, whether the mold temperature is constant, and if there is any abnormal change, it should be modified in time.
Mold trial directly impacts the quality of the product during the production process of an aluminum extrusion press. Every operator of aluminum extrusion equipment should be familiar with the equipment structure and functions of each part and memorize the use of the buttons and switches. If you don't know what else to do, you can directly contact the aluminium extrusion suppliers to avoid unnecessary losses caused by incorrect operation.
If you want to understand the aluminum extrusion press, you must start with the equipment structure. In detail, the extrusion press is divided into: main motor oil pump, auxiliary motor oil pump, main oil cylinder, auxiliary oil cylinder, movable beam, front beam, sliding mold frame, Shearing device, extrusion cylinder, supply system, plc control system, hydraulic system, electrical system.
