[China Aluminum Network] How to increase the extrusion yield? I personally have the following suggestions for extrusion operators and extrusion quality inspectors: 1) Quality inspection: Machine inspection should adopt fast, accurate and flawless inspection methods. The so-called “fast†means that the inspection is quick and timely; “quasi†means to be familiar with national standards, internal control standards, different customers and different surface treatment standards. If necessary, take a sample and do the corresponding surface treatment test. Never misjudge or exceed the standard acceptance phenomenon. In exceptional circumstances, it must be immediately reported to the relevant person in charge; â€œç‹ â€ means that the position and implementation of the implementation system are majestic. 2) Squeeze the squad leader: Do not pull the wrong mold, misprint the tracking card, and actively perform the first quality inspection and process inspection. 3) The host operator (deputy monitor): actively cooperate with the monitor to verify each set of molds, control the three temperatures, according to the structure of different models and different surface treatment to master the flow rate of the output, check the output at any time Quality status: Responsible for wall thickness, forming degree, smashing and dragging, and accurate calculation of whether the material heads after sawing the semi-finished products with different specifications are long enough. 4) Interruption: Interruption is also a very important job. When quality problems are discovered, it is necessary to tell the squad leader or the squad leader the time to rely on the time. Each dies must be inspected for the height of the lifting frame, the graphite block, and the high-temperature roll. Whether it is in good condition, because they will directly affect the degree of forming of the material, open the fan in time, and check whether the conveying process of the conveyor belt is smooth and effective. If there are bubbles on the surface of the profile, it will be marked on the profile to prevent it from flowing into the next process. 5) Straightening (Materials, Length Cutting, Framer): Before the straightening of each material, it is necessary to inspect the surface quality in a comprehensive manner, so that the profiles on the cold bed cannot be piled too much so as to avoid scratching. The hollow profile must be fitted with a suitable plug to prevent excessive deformation of the broken ends. If there is an assembly relationship, take the model of the corresponding surface treatment model of this batch of orders as a standard, in order to control the stretching rate of straightening. When mixing, pay attention to different materials for different surface treatments. Blanks, oxidized sand blasting materials, and “oxidation and electrophoresis light fabrics†try to match the non-decorative surface or the non-decorative surface with the non-decorative surface. The distance between the support and the section of the profile is to avoid rubbing, bumping, scratching, scratching or injury on the decorative surface. Before cutting to length, it is necessary to consider whether the waste material of the material tail is long enough. If it is found that the whole material or batch is not long enough, immediately notify the operator of the interruption or start-up. After sawing, check whether the deformation of the end of the material is serious, such as sawing. Deformation can appropriately slow the speed of sawing. Insulation material (orders with special instructions for bending and twisting according to customer requirements for strict acceptance, not specified in the order according to high-precision acceptance) before loading the frame must pass each platform before passing the box to be qualified, more complex shape Profiles that are easily crushed after the squeezing of the frame shall be placed on each flat tube, and products with stringent surface quality must be separated by high-temperature felts, and the slats must be neatly placed.
