Matters needing attention before extrusion production of aluminum profiles for LED tube housings

JE company extrudes a lot of aluminum profile on the machine every day. Are you curious about how our company ensures the quality and stability of aluminum extrusion? In fact, every step of the extrusion process is very important. Today, the editor will introduce to you the precautions before the aluminum extrusion of our JE company:

(1) Use advanced instruments to detect the dimensional accuracy, hardness and surface roughness of the mold on-line and off-line. The molds that pass the inspection and acceptance are registered, put into the warehouse and put on the shelf, and the working belt for polishing the mold hole is taken out when used, and the diversion mold, profile mold, and mold pad are assembled and inspected, and sent to the machine for heating when confirmed to be correct;

(2) The heating temperature of the aluminum profile extrusion tool and die before the machine is specified: extrusion cylinder: 400-450 °C, extrusion pad: 350 °C, die pad: 350-400 °C, flat die: 450-470 °C, split mold : 460～480℃, the holding time is calculated according to the thickness of the mold (1.5～2 minutes/mm);

(3) The heating time of the aluminum profile extrusion tool and die in the furnace is not allowed to exceed 10 hours. If the time is too long, the working belt of the die hole is easy to corrode or deform;

(4) In the initial stage of extrusion of aluminum alloy profiles, the pressure needs to be applied slowly, because the impact force is likely to cause mold blocking. If the mold is blocked, stop the machine immediately to prevent the working belt of the die hole from being crushed.
