Die Cast Zinc Alloy Mold is also commonly known as Dies. These molds are used for the mass-production of zinc alloy parts. Mold making used to be a difficult task before. Thanks to the CNC Machining technology mold making is now faster and more efficient than ever. Zinc-alloy Die casting Mould requires a material that has higher strength and melting temperature than Zinc. Otherwise, the die will be damaged during the casting process. Usually, steel molds are used for Zinc die casting. High-quality steel is quite costly and hard to machine. So, the die tooling cost is relatively high. Even though the high tooling cost,Zinc-alloy die casting toolings provides the best economy and quality for large volume production. Components of  Die Casting  Mold A Die Cast Mold consists of multiple parts with each serving a specific purpose. The main components in a die casting mold are listed below. >>Cover Die                                >>Ejector Die>>Ejector Pin>>Runner>>Sprue>>Cavity Insert>>Ejector Plate>>Support Plate etc.       Types of Die Cast Mold >Production Dies Production dies are used for large scale production. They are manufactured with high-quality, durable material to ensure longer die life. The initial tooling cost of production die is very high but the cost eventually drops with long term use.>Prototyping DiesThese dies are mainly used for creating prototypes. The tooling process and functionality is the same as that of production dies. But the complex features are simplified and machined with less precision to minimize tooling cost. >Trim Dies After a casting cycle ends, the parts have casting residue such as sprue, runners, risers, flash, etc. Trim dies are used for cutting down excess material from a completed die-casting. It is also used for separating the parts from a casting pattern.   Advantages of  Zinc-alloy Die Cast Mold   Zinc-alloy die cast mould has made the production of Zinc-alloy parts a lot easier. Some of the benefits of die casting molds are explained below:>A single mold can produce thousands of parts>Can produce parts with very tight tolerances>Can withstand high temperatures>Can withstand very high pressure>Significantly reduces production cost for large volume production>Can manufacture multiple aluminum parts at one go>Increased rate of cooling and solidification allows faster production>For these multiple advantages, aluminum die-cast mold is being used for boosting aluminum die casting capacity.

What's  Wire cutting ? Principle of Wire cutting: Using moving fine metal wires( molybdenum wire) as electrodes, workpiece is formed by pulse spark discharge cutting Using fine molydenum wire as a tool electrode for cutting, the wire storage cylinder causes the molybdenum wire to move forward and backward alternately, and the processing energy is supplied by pulse power supply. Pour the working fluid medium between the electrode wire and the workpiece. The workbench moves servo feed according to the Spark gap according to the predetermined control program in the two coordinate directions of the horizontal plane, so as to synthesize various curve tracks and cut the workpiece into shape Classification of wire cutting: ----Fast wire cutting, speed is 6-12mm/s ----Medium wire cutting, frequency conversion and multiple cutting functions on the basise of fast wire cutting ----Slow and high precision wire cutting, speed is 0.2mm/s Some Features of each  wire cutting      Speed  Precision Tolerance Surface Roughness Fast  Wire cutting  Fastest  lowest  +/- 0.01mm Medium Wire cutting Medium Medium +/- 0.005mm Slow and Precision Wire cutting slowest Highest +/- 0.002mm ⇒Characteristics of wire cutting technology     -Capable of procesing conductor an semiconductor materials with high hardness, high strength,high brittleness and high toughess   -Process of small irregular holes, narrow gaps and complex shaped parts   -Surface of workpiece is less affechted by heat-suitable for processing heat-sensitive materials; machining accuracy i high because of the conecntration of pulse energy in a very small range   -Electrode wire don't directly contact workpiece and has no macroscopic cutting force, which is beneficial for processing low stiffness workpieces   -Due to the narrow cutting seam generated during processing, the actual amount of metal erosion is very small, the material utilization rate is high ⇒Processing Scope of Wire Cutting Technology   -Machining of stamping dies,Including the processing of large,medium and small punch dies, such as convex molds, concave molds, fixed plates and unloading plates   -Processing of family cavity molds,powder metallurgy molds, bending molds,wire drawing molds.   -Processing templates, formming tools   -Processing fine irregular holes, narrow gaps and complex shaped parts,such as micro holes and narrow gaps in irregular hole spinnerets,jet components, laser devices, electronic devices   -Processing various special materials and structural parts, such as electonic devices, instruments, electric motors, clocks,as well as gears,thin shell devices   - Cutting of various conductive materials, especially rare and precious metals;Cutting off various special structural parts       Some Reasons For Affecting the surface roughness of Wire Cutting   The factors that directly affect the surface roughness of wire cutting mainly include electrode wire factors, electrical parameter factors, mechanical factors and workpiece factors:   ⇒Influence of Electrode Wire Factors   -Wire speed: Wire speed for fast wire cutting is 9-11m/s. If speed is too high, it will affect the smoothness of molybdenum wire operation. To ensure the surface quality of the processing ,wire speed should be reduced a much as possible   -Length of Molybdenum wire : Under constant processing conditions, increasing the effective working length of wire can reduce the number of commutations of the molydenum wire, reduce the shaking of the wire, promote the stability of the procesiing process and improve the surface quality of the processing   -Tension of Molybdenum wire: The discharge of wire cutting is 0.01mm.If wire is too loose and can't ensure a stable discharge gap during operation, it will cause unstable processing and poor surface roughness of the workpiece. Before processing, check whether the tightness of molybdenum wire is suitable. If it is too loose, tighten the wire.   ⇒Influence of Electrical Parameter Factors   -Selection of electrical parameters such as pulse width and processing peak current: The power supply used in discharge machining is a pulse power supply which is an important factor affecting the surface roughness of the machining. The surface roughness value increases with the increase of processing peak current, pulse width and pulse interval.During the processing, electrical parameters should be reasonably selected based on the processing situation.   -Feed Rate of Workpiece :During discharge machining,if the feed rate is adjusted too fast or too slow, it can cause frequent short circuits or open circuits, making the machining unstable and causing unstable stripes or surface erosion on the workpiece surface.   ⇒Influence of Mechanical Factors   -Positioning accuracy and sensitivity of the worktable: The movem...

Why need to make the Finish for Metal Part Normal metal materials of iron,Aluminum,copper have active chemical properties,If they are exposed to the air for a long time, their surfaces will be oxidized or even corroded, seriously affecting the performance of materials. Therefore, in order to make these metal materials more durable and beautiful, their surfaces are usually treated to extend their service life and increase their aesthetics There some noraml finish way for the metal: Spray Paint:Spray painting is a painting technique in which a device sprays coating material through the air onto a surface. The most common types employ compressed gas—usually air—to atomize and direct the paint particles. Electroplating：Electroplating is a surface processing method to deposit the cations of pre plated metal on the surface of the base metal by electrolysis in a salt solution containing pre plated metal with the substrate metal as the cathode. The coating performance is different from that of the base metal and has new characteristics. According to the function of the coating, it can be divided into protective coating, decorative coating and other functional coatings. Electrophoresis：Electrophoresis refers to the process in which the charged coating ions move to the cathode under the action of voltage applied at the cathode and anode, and react with the alkalinity generated on the cathode surface to form insoluble matters, which are deposited on the workpiece surface. Galvanization:Galvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metal, alloy or other materials for aesthetic, rust prevention, etc Blacken:The surface blackening treatment of steel parts is also called bluing. The principle is to rapidly oxidize the surface of steel products to form a dense oxide film protective layer, so as to improve the anti rust ability of steel products. Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Aluminum is ideally suited to anodizing, although other nonferrous metals, such as magnesium and titanium, also can be anodized. The anodic oxide structure originates from the aluminum substrate and is composed entirely of aluminum oxide. This aluminum oxide is not applied to the surface like paint or plating, but is fully integrated with the underlying aluminum substrate, so it cannot chip or peel. It has a highly ordered, porous structure that allows for secondary processes such as coloring and sealing. Anodizing is accomplished by immersing the aluminum into an acid electrolyte bath and passing an electric current through the medium. A cathode is mounted to the inside of the anodizing tank; the aluminum acts as an anode, so that oxygen ions are released from the electrolyte to combine with the aluminum atoms at the surface of the part being anodized. Anodizing is, therefore, a matter of highly controlled oxidation the enhancement of a naturally occurring phenomenon.
