How to improve extrusion yield? The following suggestions are for extrusion operators and extrusion quality inspectors to refer to:
(1) Quality inspection: The machine quality inspection should adopt fast, accurate and ruthless inspection method, the so-called “fast” means diligent, fast and timely inspection; “Accurate” is to be familiar with the national standards, internal control standards, different customers and different surface treatment standards, sampling when necessary to do the corresponding surface treatment test, must not appear misjudgment and excessive acceptance phenomenon in special circumstances can not determine to immediately report to the relevant person in charge; “Ruthless” is the position and implementation of the executive system majesty.
(2) Extrusion leader: do not pull wrong mold, do not write wrong tracking card, and actively do good quality self-inspection first inspection and process inspection.
(3) Host operator (acting monitor) : Actively cooperate with the monitor work, to verify each mold, good control of the three temperature, according to the different surface treatment of different types of structure and flexible mastering of material flow velocity condition, check out the material quality, is responsible for the wall thickness, forming degree, collapse and drag rotten or drag, accurate calculation in different specifications and varieties of profiles after cutting into intermediate material head is long enough.
(4) interrupt: interrupt is also a very important position, found the quality problem to be the first time told the monitor or monitor of generation, each mold computer out to check the discharging mouth of the lifting height and graphite blocks and hot rolling are in good condition, because they will directly affect the material forming degree, promptly open the fan, check whether conveyor belt transport process smooth and effective. If it is found that the surface of the profile has bubble oil bubble, collapse drag rotten to do obvious mark on the profile, to prevent flowing into the next process.
(5) straight work (material, fixed length saw cutting, frame) : each material in the straight line to a comprehensive inspection of the surface quality, can not let the cold bed profile pile too much, so as not to brush the injury, hollow profile to choose the right plug to prevent excessive deformation of broken head. If there is assembly relationship, take the sample of the corresponding surface treatment model in this batch of orders as the standard, so as to control the stretching rate of straightening.
When mixing materials, pay attention to the different surface treatment materials have different mixing methods, blank, oxidation sandblasting material, “oxidation electrophoretic light fabric” as far as possible the non-decorative surface down or non-decorative surface and non-decoration face together, keep the distance between the profile and the branch as far as possible to avoid the decorative surface rubbing, touching, scraping, scratching, injury.
Fixed length sawing before considering whether the material head material tail waste is long enough, such as the discovery of the whole material or batch is not long enough to immediately notify the interruption or boot hand, sawing to carefully check whether the profile end deformation, such as sawing deformation can be properly adjusted to slow sawing near speed.
Special insulation material (order indicate the bending twisting strict inspection in accordance with the customer’s requirements, not indicated in the order according to the high precision level acceptance) to frame each material must be before qualified platform to frame, shape more complex frame of every article easy to crush after profile will be separated each layer placed flat tube, strict surface quality of the products with a high temperature felt single interval, every article must be clean and tidy.
