The car is plastic fuel box is multilayer squeeze in all hollow shape technology

The atomic condition of 02mm distributings equably. A variety of mixing refine implement be used accordingly. The static state mixes refine implement, new-style drawing mixes refine implement wait to be placed to be between extruder and nose. JEW company is in what if the graph is shown 2 times,extruder screw head designed to mix refine component. Nextpage nose squeezes a type continuously multilayer squeeze nose in all, its each flow path is squeezed equably piece appear particularly important. Flow path design uses design of helix flow path more. No matter be monolayer,the advantage of helix flow path is multilayer still, each all won't appear in circumferential direction apparent fusion seams an area. But its are main the problem is the grow in quantity as number of plies, to hollow machine character, as a result of the limitation on the space, the design of helix flow path can become unusually difficult, accordingly, below the circumstance of more number of plies, also use heart form to wrap flow path of subsidiary channels in the human body through which vital energy to design, but each fusion seams an area to need to stagger distributing. Develop as the technology, the design of nose flow path, also realized the computer to emulate imitate. Large, software of the 2D that is used technically at modular head design, 3D, CAE has appeared. Qin Chuan squeezes head of large scale computer and 1000L 6 layers of group development in all store in makings nose, with respect to the large computer that introduced Futuresoft company the design analyses software FLOW2000, this software included to wrap flow path of subsidiary channels in the human body through which vital energy from form of flow path of 2D flow, 3D flow, helix, heart, squeeze a variety of analysises such as flow in all, can when imitate shows fuse-element flows inside flow path everywhere temperature distributings, pressure distributings, shearing stress distributings, stream rate distributing, detention time, can be opposite accordingly the design of flow path undertakes guidance, explore optimal plan. Use large analysis software, not only solved the past a lot of analysis consideration that cannot have, make nose design is built on credible academic base, improved the design quality of head of large scale computer, decreased to design a risk. Should say, the occurrence of this kind of large-scale software, it is the most significant technology progress inside production domain of design of model of nose, mouth. Model base wall is large control hollow aircraft nose model base wall thick control is a crucial technology. Model cent of base wall thick control is controlled for axial (AWDS) control with radial (PWDS) two kinds of forms. Axial base is had to control a function commonly on current large and hollow aircraft, its reference point differs to 256 bits from 24 o'clock, action of axial wall thick pilot is to make the huff that the material semifinished product of outpour differs according to goods obtains different ply than edge axial, make sure final product has evener wall basically thereby thick distributing, it is the mouth that the position that establishs beforehand through core model makes axial move and changes modular head the capacity will achieve the goal with change large base. Although axial wall thick control can improve the wall of goods thick distributing, but as a result of its eduction model base still is shown inside water truncat face wait for large circle, in some semmetry to the part direction has the goods that bigger drawing asks to appear still is not optimal, because this produced technology of radial wall thick control. Radial control technology can make squeeze go out model base shows the change with blame sectional circle inside the section of some requirement (it is ellipse or water chestnut circle commonly) . Combined action of thick pilot of axial wall thick control and radial wall, can acquire first-rate semifinished product, yi Ke obtains more ideal goods wall thick distributing. Technology of radial wall thick control develops today, basically formed two kinds of typical designs, type of annulus of a kind of flexibility that be called, one kind builds a form for lip. Flexibility annulus type is to pass electro-hydraulic annulus of flexibility of servo control thin wall is in or on two symmetrical direction be out of shape will change crowded piece model the ply of base. No matter boast the product that makes what appearance,its characteristic is, want its only buccal model diameter is changeless, radial control can produce effect. The fatigue life that the main problem that this structure exists is flexibility annulus is finite, incidental attaint, and change make price of a pair of new flexibility annulus spare parts costly. Lip builds a form change base wall is large the fluctuation shift that relies on to build form mouth link will come true. Written guarantee with flexibility annulus compose photograph is compared, its biggest advantage is service life grows, and once need to change, have main opportunity the factory of process capability can be assumed. In some designs, the loose piece of make it of the part that build a predestined relationship of buccal annulus is embedded, went to the lavatory to change, reduce the cost when changing. A company has England the patent of this technology. Technology of radial wall thick control is large to rising the quality of hollow goods is an effective method undoubtedly, at the same time it still can be in assure quality while, reduce the quality of goods. But add a large radial wall the additional cost of thick control equipment also is taller, it is with the quote of SIG company exemple, the pattern of annulus of flexibility of Φ 220mm diameter that matchs to take two servo oil cylinder is radial controller, its quote is mark of 20 more than Germany. High cost, restricted an user to choose radial wall thick controller extensively, especially the user of large and hollow machine. To the hollow machine of 1000L above, because create the difficulty that go up, equipment production manufacturer also does not offer radial wall commonly the equipment option of thick control equipment. Replace as a kind, a lot of users lack the inadequacy of radial control equipment to make up for, adopt a kind simple but the method that also is effective, namely core model writes form law. Its are specific course of action is to be on the nose that has function of axial wall thick control, to its the specific place of core model has long look, be in thereby axial pilot at the same time, obtain approximately in the wall on radial the profound change that be not a circle is measured. Of course, this kind of long form needs to have certain experience, should the circumstance of concrete analysis goods, compile volume of the position of form, azimuth, long body and the figure of long form certainly thereby, strict semmetry should notice when long form commonly. Large and hollow machine still can be used at the production of a variety of products, among the case of hollow have enough to meet need that if outdoor is hollow desk and chair, dismountable,uses, freeway segregation board. A few spare partses on the car also can be used hollow the method that blows model is made, if seat, ventiduct, faze flows board, plastic fuel box cheers a canal to wait. Above goods is used store hollow mechanism makes makings type. If have a demand to sex of ooze of fuel box block, box of plastic fuel cheers a canal to also can be used multilayer squeeze hollow machine to shape in all. CNC Milling
