Grim economic situation is being perplexed develop the industry of the film that blow model of the area, at the same time this also aroused people to throw older flame to replace a technique, more the product of small lot of economic ground production. Squeeze the innovation design that exports a model, its meaning depends on bringing bigger profit to process trade. The change that individual family expenses food packs and the driving force that buying a habit initiatively is progress of this kind of technology. Equipment of the film that blow model produces Andy Barns of selling manager of business Davis-Standard Europe to think, it is very cheap to be like shopping bag as a result of the daily expense general merchandise that imports from Asia and Western Europe, accordingly to developing this one market is in for the area atrophic, because this develops,the film of the area produces business the business to maintain oneself, begin to deliver the view to those small lot products. Current, already very much businessman turns to the look low those who use production of material of polyethylene of C8 linear low density is metric, multilayer film or luxuriant metal polyethylene and unconventional material if PET (get together pair of benzene glycol ester of 2 formic acid) , styrene - butene copolymer, tall fuse-element. What operate new facility to emphasize easily is versatility, easily maintenance, outstanding crop and quality. For example the side of Macro Engineering company feeds makings mouth model, the equipment of fabric width of 300 ～ 550mm is simpler than the equipment previously, there are 13 main mould fittingses to need to disassemble only in 7 buccal model maintain and clear. Differ with the buccal model of thin pancake type, the cone-shaped design of MacroPack mouth model is had from sealed effect. Each components of buccal model are mutual and built-in, sell aperture decreased to be reduced effectively defend leakage performance. Equipment of 7-Layer Patented MacroPack Die produces the model of mouth of REDI (REgular DIvision) that business Addex introduces, development direction of future also tends simplification (March 2000 MP/MPI) . Every annulus contains at most dismountable component, can decrease thereby the maintenance of 25% and clear the job. As similar as REDI mouth model, hosokawa Alpine company provided head of redesigned K series model. Polymer fuse-element is fed allocate annulus, flow and making a fluid perpendicular is not horizontal flow, this ensured the stability of fuse-element pressure, conduce to divide evenly fast ground is cut, make a fluid can even pour out of. This kind of design conduces to not only reduce retention period nearly 20% , and clear faster. The Varex of Windmoller&holscher blows model to shape the Maxicone mouth model of filmy product line, the design is more compact, fuse-element flow path is short, retention period is briefer. Appearance of buccal model geometry fuse-element capacity the smallest change, reduced fuse-element retention period, relaxed settlement cut off crucially model colophony machines a problem. The meaning of dimension to Reifenhauser company character, dimension sense is great, blow model to shape especially the height of filmy mouth model. The model of new-style HDS mouth of this company, than before all buccal model size are small 30% . HDS is model of mouth of a kind of small size, because this is being used,cut off costlily model the dimension of model of the mouth when colophony becomes particularly important, use least colophony gets most product and did not break little more than material, have very important sense to each production business. Current, a lot of clients are in it is OK to ask for the buccal model that small lot produces, the client because of them the finished product that orders goods the quantity is small lot is filmy. HDS can make disassemble mould, clear include refrigeration to be finished inside 10h, and traditional pattern needs a week. Accordingly for the user to Reifenhauser, use new pattern to produce cost to be able to be reduced 20% , because new pattern is fewerer than the component of old pattern, and mould dish the mould of unlike tradition needs special hydraulic pressure tool to disassemble in that way. 9 Optiflow LP of HDSBattenfeld Gloucester (low exterior) mould of the film that blow model, dimension has the in part of mould of traditional accumulation type only, each core model is homocentric distributing, mutual cascade, reduced mould height, thereby more easily installation, operation and maintenance. In the meantime, this kind of design increased fuse-element liquidity, reduced fuse-element retention period, and the quality that still improved film. CNC Milling
