普通钻床改造为多轴钻床 外 文 文 献 It is the new-type inject by shaping technology 1. inject by shaping altogether( inject shaping of at core layers) Adopt and inject shaping help and observe and make one unique structure altogether. first of plastic is injected and fill and enter 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 and the materials quantities of second according to correct proportionate relationship, Make one at first complete at second to make one parcel appearance core each. In addition, in cosmetics application, the material is put after second material injecting to 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 mould mould sandwiches what 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 m
