  • Q What is zinc plating?

    A Zinc plating is the process in which parts are charged via racking or barrel contact and the protective zinc coating is adhered within the bath. A protective chromate is applied after the zinc providing a greater protective finish depending on the color type of chromate applied.

  • Q What are the common surface treatments in Fuchun foundry?

    A

    Surface protection can be divided into electroplating, coating, chemical treatment layer.

  • Q What surface finishes are available on stainless steels?

    A

    There are many different types of surface finish on stainless steel. Some of these originate from the mill but many are applied later during processing, for example polished, brushed, blasted, etched and coloured finishes.
    The importance of surface finish in determining the corrosion resistance of the stainless steel surface cannot be overemphasised. A rough surface finish can effectively lower the corrosion resistance to that of a lower grade of stainless steel.

  • Q What is welding?

    A Welding is one type of metal joinery, in its basic form it involves superheating two metals at the point of contact in order for them to bond.

  • Q What materials are best for investment casting?

    A Most metals that can be melted and poured can be used for investment casting. The most common metals are stainless steel, nickel-based steel, cobalt-based alloys, brass, bronze, and copper.

  • Q Are investment castings expensive?

    A While investment castings can be slightly more expensive than sand cast, forged, or some machined parts, they make up for higher cost through the reduction of machining achieved through the near net shape tight tolerances that can be held as cast.

  • Q What kinds of parts are suited for investment castings?

    A Almost any configuration or design can be produced as an investment casting. Investment castings offer more design flexibility over any other manufacturing process. 

  • Q What are the size limits of investment cast components?

    A Our products range from 100 grams to 600 kilograms in weight.

  • Q What are the benefits of an investment casting?

    A
     The investment casting process offers lower costs, greater design freedom and the largest selection of alloys to work with.
     

  • Q Advantages of investment casting

    A
    Excellent surface finish
    High dimensional accuracy
    Extremely intricate parts are castable
    Almost any metal can be cast
    No flash or parting lines

  • What is magnesium?

    Magnesium is: among 1) the lightest of all metals (63% of aluminum, 38% of titanium); 2) stronger than engineering plastics; 3) 100 times better in heat dissipation than plastics; 4) electromagnetic-shielding; 5) best in vibration absorption of all metals; 6) environmentally safe (non-hazardous and recyclable); 7) easy to machine; 8) abundant in supply (sixth most abundant on earth).

  • How Are Die Castings Produced?

    First, a steel mold capable of producing tens of thousands of castings in rapid succession must be made in at least two sections to permit removal of castings. These sections are mounted securely in a machine and are arranged so that one is stationary (fixed die half) while the other is moveable (injector die half). To begin the casting cycle, the two die halves are clamped tightly together by the die casting machine. Molten metal is injected into the die cavity where it solidifies quickly. The die halves are drawn apart and the casting is ejected. Die casting dies can be simple or complex, having moveable slides, cores, or other sections depending on the complexity of the casting.

  • What Are ABEC And ISO Precision Level Equivalencies?

    ABEC precision levels, ABEC-1, ABEC-3, ABEC-5, ABEC-7, and ABEC-9 are the equivalent to ISO precision levels P0, P6, P5, P4, and P2 respectively.

  • What Are ABEC Ratings?

    The ABEC scale is an industry accepted standard for the tolerances of a ball bearing. It was developed by the Annular Bearing Engineering Committee (ABEC) of the American Bearing Manufacturers Association (ABMA). There are five classes, going from widest tolerances to tightest: 1, 3, 5, 7, and 9. Higher ABEC classes provide better precision, efficiency, and greater speed capabilities, but do not necessarily mean that the bearing can spin faster. Additionally, the ABEC rating does not specify many other critical factors, such as smoothness of the rolling contact surfaces, ball precision, and material quality.

  • Can you use our existing pattern equipment as it is?

    Where a customer has existing pattern equipment, we will usually be able to use it to produce the required castings. However, it may require some modification in some instances to fit in with production methods.
