restarting the simulation with modified diecasting process con- ditions, based on the previous or next-to-last casting cycle. Sand casting processes can be resumed with different condi-
tions at the end of any process stage. Te automatic enmesh- ment of complex geometries has been simplified with new enmeshment criteria and procedures. MAGMA5 is modularly expandable for specific processes,
materials or quality aspects: • MAGMAiron, MAGMAsteel, MAGMAnonferrous— material-specific modules allow the prediction of microstruc- tures and properties and consider alloys and metallurgy.
• MAGMAhpdc, MAGMAlpdc, MAGMApermanent- mold, MAGMAwheel—process modules allow the consideration of specific process requirements and control of the manufacturing process.
• MAGMAcore+mold, MAGMAdielife—products and functionalities for the prediction of core shooting, gas- sing, and purging and the assessment of die life aid in making the best use of available knowledge.
• MAGMA HT thermal, MAGMAstress, MAGMA- link—modules for simulating stresses of the component after casting, heat treatment, or machining and the ex- change of information based on simulation results assures the design of cast parts for their performance. Stress simulation results can be prepared for faster post-pro-
cessing. For the quantitative assessment of casting distortion in the measurement perspective, it is now possible to compare the virtual measurement with the real part geometry. In addition, a new database of riser sleeves, generated by ASK Chemicals, is now available. Casting process simulation allows designers to optimize
designs by ensuring the desired material properties without maintaining excessive safety margins. It also facilitates com- munication between development, production, management, sales and casting buyers to ensure castable parts are produced
置点”功能可以灵活地随着压铸工艺条件的修改重启 模拟。
砂铸工艺模拟可以在任何过程阶段结束时随着不同 的条件而重启。采用新的网格划分标准和程序，复杂 几何体的自动网格划分得到了简化。MAGMA5可根 据特种工艺、特殊的材质及质量要求增加扩展模块。 • MAGMA铸铁、MAGMA铸钢、MAGMA有 色金属（特定材质）模块可实现微观结构和性 能以及合金和冶金性能的预测。MAGMA高 压、MAGMA低压、MAGMA金属型、MAGMA 轮毂工艺模块考虑到特种铸造工艺的要求以及制 造工艺的控制。
• MAGMA射砂和MAGMA模具寿命模块可对射 芯、排气、换气、模具寿命进行模拟及预测，有 助于最大程度地利用有效的知识。
• MAGMA热处理、MAGMA应力、MAGMA链接 模块模拟铸态、热处理、机加工后的应力以及基 于模拟结果的信息交换，保证铸件的设计达到使 用性能的要求。
应力模拟结果为更快的后处理做准备。为了定量评 估铸件尺寸的变形，软件程序可把虚拟尺寸同实际尺 寸进行比较。此外，一套新增加的由ASK公司提供的 冒口套数据库也可供使用。
铸造工艺模拟可以通过确保想得到的材料属性而 不保留过多安全边际的前提下优化工艺设计。工艺模 拟也能促进研发、生产、管理、销售人员以及采购商 之间的沟通，保证按照客户规格及时生产出合格的铸 件。

New Diecasting Technology Opens a Wide Range of Applications Current trends such as lightweight construction in the au-
新的压铸技术开辟更广的应用领域
tomotive industry or the pressure to manufacture increasingly better products at lower cost require creative diecasting solu- tions. An innovative answer to this is the “Lost Core” technol- ogy (salt core technology), from Buhler, Uzwil, Switzerland. What the automotive industry is calling for is cost
reduction, integral design (reduction in the number of components) and higher productivity. Te “Lost Core” technology opens up diverse opportunities for this. With this technology, certain parts of the component to be cast are recessed with a salt core, which is then rinsed out again. Tis makes it possible for permanent mold and sand cast components to be replaced while providing the full benefits of diecasting, such as material savings, shorter cycle times and reduced post-processing. “Lost Core” enables the development of completely new
汽车结构轻量化的趋势以及更高性价比产品的制造压 力需要创新的压铸件解决方案，来自瑞士布勒公司的一 种“可溶芯”（盐类）革新技术可以满足以上要求。 汽车产业的发展要求是成本缩减、设计整合（缩减部 件数量）、更高效的生产率，“可溶芯”技术拓展了满 足这些要求的机会。使用盐芯，某些带有内凹的零件可 以压铸成形，盐芯之后可以用水冲洗掉。这也使得压铸 工艺部分取代金属型或砂型铸造成为可能，从而实现压 铸工艺的所有优势，如节省材料、缩短生产周期、减少 后处理工序等。
“可溶芯”技术能够开发全新的零件，其内部可包含 68 |
