or in a certain plan of design skillfully. Understand at results and can't process in order that it is by research object /materials from prerequisite. After consider adopting this kind of method accurate data-in , can make enormous benefit . In addition, economic make design cycle not to be short and needs produce shorter time the analysis. The one that should point out is, commercial cae procedures usually can't be used directly. It fills and imitate and produce valuable experience but the result must rethink its limitation to estimate again . Use modern computers go on and inject shaping simulated test and limited to pure viscidity fluids only( include the melting plastic of viscoplasticity ). One actual flow form measurable melting body person who flow intoes and performance announce etc. structure by speed, If can carry on the viscoplasticity analysis of high accuracy . At present adopt any other to process way reach this advanced competences, And recent years, at emulation the industrial circle person who take the leads of equipment and the research groups of university already made good progress. Have several a of companies make great efforts and probe emulation technology, in order to be be able to be being explained moulding the sex instinct act and process the phenomenon of more reality correctly. For example, get together on the influence that the orientation of the possessive chain is distributed to some physics performance and performance . Processing physics is very complicated, but some viscoplasticity is embodied too alike to still totally understood , Perfect the rational processing way and taking shape slow at present even more. These stronger strong ways will be exceeded the production capacity that will be designed at present greatly .
Inject By Shaping Altogether( inject shaping of at core layers)
Adopt and inject shaping help and observe and make one unique structure altogether. \some types first, then the plastic: \second\follow \first\inject person who enter one and keep initial to drive pressure field of flowing closely. At epidermis district and core the sizes of one, measure and publish\first\proportionate relationship, Make one at\
make one parcel appearance core each. In addition, in cosmetics application, the material is put after\have\first\of epidermis of the small part, So that the epidermis of the part of the runner can be totally closed. Inject making one of shaping altogether with the resin of 2 kinds of different colors, form a piece of a layer of blocks of epidermis and core apt to distinguish (Realize inject shaping one as much as all have and have and one very much important this core similar epidermis. )If there is not advanced detection technique, usually difficult to distinguish the epidermis - core area and boundary of layer. Inject shaping a new technology altogether. British ici company began to use this technology in the 1970s early, and had made the basic theory of including, Produce several patents, such as the products and machinery equipment,etc.. Now similar to \has been adopted generally ici production technologies,last outer the materials of the epidermis at moulds and in layers is material different on core occasionally, So two a kind of material person who a certain one inclusives, and core require and have high radiations very, issue and steep shaping and retrieve performance of utilizing etc at 100% by layers of material. Should be fixed relatively by the excellent choice to select the material for use. After injecting the shaping technology and come out in 15 altogether, can really just popularize and popularize . One a kind of adoptions inject the thick teeth of shaping fails and produces horizontal cross-section altogether. Material to pack nylon epidermis, and pearl material pack the nylon at - - glass layers of material core. A rate that shrinks material of pearl of glass is extremely low in core one, have good size stabilities. Nylon prevent pearl from grains of material easy problem of denuding that produces by epidermis person who give good and lubricated tooth tooth gear wheel. Already developed several kinds and processed the method of improving new-typly at present on the basis of the basic theory of injecting shaping altogether. At however, in the mould\processing method to adopt low molecular weight polymers as the outer material, Gas assist mould mould shaping to adopt the nitrogen or another kind of gas as the core one( or core ones) material. Produce and process
equipment constant to perfect and improve, satisfy of different use newly and the new technologies demands with product design, Inject technology and will become the rich and potential industrialized extensive production technology method altogether. Reversal Inject Shaping
Comparatively speaking, it is that a relatively new inject shaping chooses parameters that the reversal is injected. The greatest difficult point of this technology is lain in when processing the condition suddenly changeses, To the thing that it will be known little about what kind of change behavior plastic melting body will demonstrate . About the rudimentary knowledge of melting body rheology, is not merely the regular shear . Say exactly , the melting body responds( the viscidity and elastic behavior) the characteristic needing expressing, Not only common stable state flow speed or shear speed and temperature, but also including pressure and flow the speed in the twinkling of an eye. These characteristics including a lot of content and very difficult to understand. However, if not in heterotypic materials inject respect make substantive progress, need and make and publish many kinds of different the concrete operational procedures of plasticses. Need and increase a in common use one tired to try on law is in order to getting ripe and accurate control method also another. During routine inject shaping, the type immobilizes in a of walls, some situations are left, Still utilize and filling on the mould and protect and press and fall section and move the mould wall . Can adopt 2 kinds of different methods : Person who move s of perpendicular on dividing into mould line direction wall; Rotate a of walls of the slipping type . Fill stage rotatory type cores with increasing mould. Through this kind of processing technology, the crooked performance and other mechanical performance of making one has gotten great improvement. Polyphenyl drink the water and polypropylene syringe adopt cup the processing method get great to change and break through the ground 2 a piece of products just by second
