【正文】 duplication the photosensitive material on the mold cavity surface, process chemistry processing, the mold cavity surface does not form by the etching partial protectors, then acts according to the mold material quality, the choice corresponding etching craft, pattern design etching in mold internal technical main characteristic is the time short, the expense is low, patching damages the pattern design to be possible to achieve flawlessly. 3 sprinkle to cast into the type system mold technique Sprinkling to cast into technical and mon characteristics of the type system mold is according to the kind piece for basis, sprinkle a convex and cave mold, a surface do not need the machine to physically to mainly have following several categories type in the mold. 4 extrusions takes shape the technology Using the berylliuim copper alloy good thermal conductivity and the stability, after the solid melt aging treatment of metal, use the swaging pressure to make the mold concave model cavity. Its characteristic is makes the cycle short, the cavity precision is high (the IT7 level), surface roughness Ra= mu m, The intensity is high, the life may reach 500,000 times, does not have the environmental pollution. This technology is using the metal material in the thin crystal grain, certainly takes shape the temperature, under the low distortion speed condition, when the material has the best superplasticity, toes attend to carry out raised mold which the initiative finishes, then may extrude the concave mold with the small strength one kind of fast economical pattern making technology. Ultra models takes shape material typical representative is Zn22%AL. 5 does not have the mold multi spots forming technology Does not have the mold multi spots fast forming technology is by CAD/CAM/CAT The technology is the main method about, may adjust the base main body group highly using the puter control to form forms the surface, replaces the traditional mold to carry on the three dimensional curved surface forming to the sheet an modern advanced manufacture technology. This technology may change the distortion way and the stressful condition at will, enhances the material the formed limit, may form repeatedly, by this elimination material interior remaining stress, the realization does not have 4 the snapping back forming 6 triumphant Uygur bright steel belt blanking falls the material pattern making technology The new steel belt blanking falls the material pattern making technology is one kind is different with has raised, the concave mold structure steel belt mold generally, it is with specially makes the new fast economical pattern making technology by the single edge steel belt which the backing strip is posed. This kind of mold weight is light, only then 200kg, the processing precision for 177。s favor and the concerned leader department39。在成型概念上以平面離散、堆積為指導，在控制上以計算機和數(shù)控為基礎，以最大柔性為總體目標。其特點是制造周期短，型腔精度高 (IT7 級 )，表面粗糙度 Ra= m,強度高，壽命可達 50 萬次，無環(huán)境污染。 快速換模技術 由于產品品種的增多，使模具在生產中更換變得十分頻繁，于是如何縮短沖壓設備的停機時間，提高生產效率，快速換模技術受到了人們的關注。隨著商品經濟的發(fā)展，激烈的市場競爭，產品更新?lián)Q代的加速，對快速經濟制模技術在縮短周期、降低成本，提高精度和延長壽命方面的要求勢必會越來越高。它可以用來加工板料或型材的沖孔、落料、切角、切槽、切斷及淺拉伸等。這種模具重量輕，一般只有 200kg，加工精度為 177。該技術主要特點是節(jié)省材料、模具制造周期短，電鑄層硬度可達 40HRC，提高了耐磨性和壽命，粗糙度、尺寸精度與樣模完全一致，適用于注射、吸塑、吹塑、搪塑、膠木模、玻璃模、壓鑄模等模具型腔及電火花成型電極 蝕刻技術是光學、化學、機加工綜合應用的一種技術，它的基本原理是先把花紋圖案制成膠片，再把膠片上的花紋圖案復制在已涂上光敏材料的模具型腔表面上，經過化學處理，模具型腔表面形成不被蝕刻部分的保護層，再根據(jù)模具材質，選擇相應蝕刻工藝，將花紋圖案蝕刻在模具內表面上。計算機、激光、電子、新材料、新技術的發(fā)展，使得快速經濟制模技術如虎添翼，應用范圍不斷擴大，類型不斷增多，創(chuàng)造的經濟效益和社會效益越來越顯著。 On the other hand enterprise in order to satisfy the multi varieties, the product renewal quickly, wins the market the need, requests the mold to turn towards the manufacture cycle to be short, the cost low fast economy direction develops. The puter, the laser, electronic, the new material, the new te
