The laser on plastic gasoline tank codes

Kautex.

De) management move covers an area of a face to accumulate 70 thousand square foot factory, have product line of 9 plastic gasoline tank. The factory builds A Weila 1993, the branch that Inc. of German Kautex Textron is in the United States is at the beginning of founding, now is the subsidiary of American Textron company, this factory 2003 by " industrial weekly publication " judge for optimal factory, call this the company " have broad perspective, and the improvement of craft drives his to enter world top class range " , make one of top plants of the United States. " industrial laser solution " the IT manager Gene Collison that English edition magazine covered this company and Glenn Suever of advanced control engineer, company of understanding Kautex Textron (the following abbreviation " Kautex " ) the situation that replaces polyethylene label with laser technology. Gasoline tank of gasoline tank construction ever was monolayer plastic structure, do not accord with the requirement that volatile hydrocarbon discharges. Multilayer gasoline tank accords with total arrange of American environmental protection to put horizontal standard about the platoon of the hydrocarbon, old since this one standard is rising all the time. Gasoline tank by 6 plastic composition, among them one is to prevent a hydrocarbon to volatilize the protective screen in air. This one process is similar to multilayer sandwich wraps bagging, can let water portion enter inside and cut off air outer, what maintain sandwich thereby is fresh. The fuel system that Kautex compose builds is used on car of the great majority on the world now. Be in the United States, this company is annual now ship to general motors, Ford, Kelaisile, Feng Tian and the company such as this cropland 1.2 million gasoline tank. Motor Corporation basis is punctual change goods in stock to plan to undertake purchasing, if appear,because of product line of this gasoline tank breakdown will cause serious other people sort a problem. Collison expresses, although gasoline tank is empty, they also occupy a lot of spaces, because this Kautex is holding inferior goods in stock all the time. Accordingly, if the product line of the company appears problem, meet not only the production of roily Kautex, also can change when alignment (JIT) the effect with client same generation. Kautex use high density spends polyethylene plastic production gasoline tank, the carbon black on besmear of outer layer is lubricious. Company use laser etchs even black is outer the surface, leave the mark of palm yellow, already clear Yi Jian, can be come out by scanning again. Kautex uses black-and-white polyethylene label at the beginning, but when the product is being offerred for Ford company after two years, this company tries to use Nd:Y of diode pump riversideAG solid laser etchs on gasoline tank a label. Etch the writing that come out is very clear, but in etch Code 39 the effect when form code not beautiful. Kautex tries to optimize laser technology, but etch the acute line that come out (read by the scanner take) , never reach the class A mass of expectation. Of fiber-optic laser introduce accordingly, kautex invites ID Technology company to reveal Macsa F-9000 fiber-optic laser and the Marca software that are based on Windows. ID Technology company brought a system, use code of a few form to undertake process designing. Kautex needs to count a hour originally or several days of ability obtain a form of a qualification to pile up, use this to cover a system to be able to be obtained instantly almost. The carbolic black with outer gasoline tank can draw the energy that fiber-optic laser gives out, make color turns into shallow palm is Brown, for subsequently read take the contrast that provided place to need. People can control this one software, need not deepness etchs also can obtain good contrast, because deepness etchs,may damage the integrality of gasoline tank, still can be opposite the line brim of a form code produces negative effect, increase thereby read extraction difficulty. Laser etchs tag number must assure to be in at least 10 years inside still readable take. The company records a database to undertake maintenance to gasoline tank production, can be used at date from or protect character. We enquire, the deposit salt on road surface kind whether can you be opposite does the definition of mark produce an effect? Collison expresses, present requirement is to make car manufacturer OK read take paper label or polyethylene label, accordingly to with the laser of data of indication Kautex of form code format etchs for label, the requirement also is identical. As lower as apparent cost presswork label photograph is compared, does laser etch He Hao is in? Collison and Suever reply: Presswork label need often undertakes maintenance to mechanical printing machine, and laser etchs reduced this on one hand the job, reduced the cost of label, reduced the cost of ribbon, and decreased to change the time that label coils. They point out the fixed facility cost of laser is high, but operation cost is low. Printing machine upholds charge tall, shut presswork ticket machine and the cost that start again are high, can create a few waste always when restart in addition. And the word of use laser, can run continuously. They admit to be in at the beginning laser is costlier, but laser is not bad news material, can offset consequently the operation cost of paper label. May more important is, use laser can assure to etch the information on gasoline tank, and label may be in change or the process carries in new outfit in by tear to shreds. Administrative layer from use laser with respect to support at the beginning, see when them laser is in operation cost is photogenic than pressworking label craft can managing cost, also no longer issue of cost of apprehension high investment, they hope to use an effective technology, and uphold charge inferior. The certain data that Kautex provides the client -- date / time and product model -- also join laser to etch in label. Paper label of the client also contains a form of Kautex to pile up number, accordingly once paper label is missing, also method uses laser to etch label will track gasoline tank. Collison is conjectural, use 2 dimension morely as car line of business form encode, car manufacturer may decide laser to etch this road. Code39 form code inadequacy grows 4 inches. This is number of serial of word of a 16 digit, can have 20 character at most. Code128 or 2 dimension encode are more reliable, but they may need to change controller of product line scanner, because its cannot be read,take 2 dimension form code. Kautex company in operation 9 product line, among them 3 use laser etch label. Kautex ever had considered to use the fiber-optic laser of other laser supplier, but compare with the solid laser that uses at present, result not more outstanding. Collison expresses, distinction depends on the pulse frequency of Macsa laser outputting, he thinks this is crucial to its application. Etch the technology with current technology is: Undertake on mould machine laser etchs at the beginning, at that time gasoline tank temperature still is close to 80 degrees, although the glove on the belt also cannot have an operation. Gasoline tank is shaped by moulding, but plastic have not shape. Laser equipment along carry line work, in order to ensure every are versed in craft appropriate ground is finished. Every component of the equipment on Kautex company product line must can read the result that takes laser to etch clearly. After patternmaking craft, every gasoline tank still needs about 5 make move to 6. Scanner of test and verify is gone to by installation near laser, because this gasoline tank is in,the meeting after the course etchs is gone to by manipulator belt the position of scanner of test and verify, whether to etch certainly by scanner of test and verify correct. If etch incorrect, can give out admonitory sound. The cycle time of every gasoline tank is controlled in 1 hour, among them 45 minutes are used at refrigeration and stabilizing agent operation. Next laser etchs mere need 5 to 8 seconds of time, depend on the amount of number information. Back-to-back move is valve solders operation. It is installation next again fuel pump, guide leak test of epicene examination, pressure and set thermal insulation board other perhaps and exterior spare parts. Kautex company already 7 × run product line of its gasoline tank 24 hours more than 1 year. Paper makes label can be brought stop the problem of machine. Routine of cooling system need safeguards solid laser, but laser of fine of wind cold light does not need routine to safeguard, this carries 24 hours a good news is for the company of travel to 7 × , because the company does not need,close product line to safeguard and enforce. Because fiber-optic laser does not need to safeguard, the worry also decreases greatly, because this is fiber-optic,laser is having very good cost advantage. Product line of the first fiber-optic laser moves in the put into production at the beginning of this year. The first after put into production comes from the business of this cropland namely. When whether the company that be asked about is satisfactory to fiber-optic laser, collison and Suever answer say to still more fiber-optic laser are in in the plan, ford product line will buy two fiber-optic laser again, and if client approve of uses this kind of technology, so any new product line will use fiber-optic laser.
