Demand For Zinc Die Casting Is Everywhere

  • Zinc die casting is an indispensable part of daily life. The different material properties of zinc and the molding options offered by die casting complement each other perfectly. Which are feasible and which are possible alternatives or combinations with other manufacturing processes and materials in the future.

    Demand For Zinc Die Casting Is Everywhere

    Due to its different material properties, zinc is the most commonly processed metal after iron, copper and aluminum. Die casting is an ideal choice for manufacturing zinc and its alloy parts. This molding process is one of the most economical molding processes. It is to flow molten metal into the divisible mold at high speed in the die casting machine under high pressure. The internal contour of the mold is presented and can be taken out from the mold as a part that can be almost installed after curing.

     

    The zinc alloy provided for this purpose has a relatively low melting point range (380 ° C to 390 ° C) And very good flow performance. Therefore, it is possible to cast thin-walled parts - thus meeting the standards of resource efficiency and weight reduction - and create fine surface structures in the process. Die casting zinc parts also have good mechanical properties: for example, the tensile strength of alloy zp0410 (znal4cu1) is 330 MPa, which is close to that of structural steel (from 340 MPa), and its specific gravity is 6.7 kg / DM ³ Specific steel (7.9 kg / DM) ³) Light.

     

    Characteristics Of Zinc Die Casting

    Zinc die casting also has the characteristics of corrosion resistance, shielding electromagnetic radiation, and can be refined by various surface treatment processes. Finally, die cast zinc can also be recovered 100% without loss of quality. For example, the tensile strength of alloy zp0410 (znal4cu1) is 330 MPa, which is close to that of structural steel (from 340 MPa), and its specific gravity is 6.7 kg / DM ³ Lighter than steel (7.9 kg / m3).

    Zinc die casting is an indispensable part of daily life. They are used in the automobile industry, machinery, instrument and equipment manufacturing, electrical engineering and electronics, household appliance industry, health industry, medical technology, and construction, furniture manufacturing and toy industry. As the latest zinc die casting competition shows, the potential of zinc as a material has not yet been fully realized.

     

    Excellent die casting

    The event is part of the die casting trade show, which is held every two years in Nuremberg and the 8th in January 2020. The zinc die casting award was awarded to the product group "automobile", "health technology", "lifestyle", "electrical engineering and Mechanical Engineering", "medical technology", "safety and locking technology". A panel of experts from zinc metallurgy, die casting machine manufacturing and research and professional associations evaluated more than 20 parts submitted by the die casting plant. The standards of innovation, structure and design, complexity, difficulty, surface appearance and implementation in mold manufacturing and production were evaluated.

     

    Possible combinations

    The award-winning workpieces show how to meet the different requirements of workpieces by combining the material properties and molding options provided by die casting. In this way, large, thin and stable parts can be produced at the same time. An example of this is the canopy wreath of the overhead shower, which is awarded in the category of "health technology". This part replaces the brass part milled by solid material diamond. Although it weighs more than 2kg, it can still meet all the requirements of surface smoothness, functionality and appearance. Die castings can be electroplated to produce a variety of surface colors.

     

    However, die casting can also be used to produce solid, dimensionally stable and dimensionally stable filament parts. This is the case with the fan bus with the connector area, which replaces the traditional wiring. The component is the winner of the category "electrical and Mechanical Engineering" and contains a cross section of about 1 cm ² The longitudinal channel, which must accommodate four conductors of one tenth of a millimeter in diameter. By wrapping the parts with plastic, they are insulated to improve stability and prevent damage.

     

    The combination of die cast zinc with another material used here should open the way for further application possibilities. It must accommodate four conductors within a tenth of a millimeter in diameter. By wrapping the parts with plastic, they are insulated to improve stability and prevent moisture.

    The fact that very fine-grained surfaces can be produced using zinc die casting technology is demonstrated by a small statue about 5 cm in size, which is the winner of the "lifestyle" category. It comes with a model made of die cast zinc, which exactly mimics its model, a leather case with leather corners for edge protection, just as it did decades ago. On a scale, the corners of the housing protrude 0.2 mm from the body of the housing and the cover protrudes 0.5 mm all the way.

     

    The parts made of die cast zinc can achieve both technical function and aesthetic effect. The basic carrier of auto transmission gear knob, which won the "auto" category award, has high strength, elegant appearance, cool and elastic. In addition, the part weighs only 150g and the driver's hand feels comfortable.

     

    Some parts must have high material strength and high matching accuracy, so they must be machined. As the winners of the "safety and locking technology" category have demonstrated, this expensive treatment can be saved, with a set consisting of a top cover for the housing and lock cylinder. Another advantage of die casting technology is that large quantities of products can be produced economically and in a resource-saving manner with repeatable high quality.

     

    Although some die casting parts focus on filament and thin wall, there are other parts that must meet the high requirements of quality, volume, thick wall, tightness and accuracy. This includes die cast housings for dental X-ray equipment“ The winner's enclosure in the "medical technology" category is designed to be used as a container to hold X-ray tubes together with transformer oil. The castings are sealed and shielded from electromagnetic radiation. Therefore, the lead coating can be largely eliminated when such castings are used. Since the entire assembly has additional zinc die cast attachments, the fastening points on the housing must be considered during the casting process.

     

    Know how and tool technology

    It is also necessary to consider the role of die casting machine and mold in order to produce flawless die castings. Their construction requires a high degree of professional knowledge and the use of computer-aided simulation process, because many influence variables must be considered, and these variables also affect each other.

     

    Zinc die casting competition and zinc initiative

    The zinc die casting competition was organized by the zinc initiative, which brought together manufacturers of zinc, zinc alloys and zinc based semi-finished products, manufacturers of zinc compounds and processors and zinc recyclers, as well as metal associations and the general manager of the non-ferrous metals industry. The zinc initiative, in cooperation with national and international zinc associations, serves as a point of contact for authorities, users, media and individuals on all matters relating to zinc.
