Frequently Asked Questions

Q: What is Rare Earth?
A: The Rare Earth or Rare Earth elements are a set of seventeen chemical elements in the Periodic Table, specifically the fifteen lanthanides including Lanthanum (La), Cerium (Ce), Praseodymium (Pr), Neodymium (Nd), Promethium (Pm), Samarium (Sm), Europium (Eu), Gadolinium (Gd), Terbium(Td), Dysprosium (Dy), Holmium(Ho), Erbium (Er), Thulium (Tm), Ytterbium (Yb) and Lutetium (Lu), plus Scandium(Sc) and Yttrium(Y). Rare Earth is usually abbreviated as RE.
Q: What are the features of Ka Shui’s Rare Earth Magnesium alloy?
A: The Rare Earth Magnesium alloy of Ka Shui is able to improve the fluidity of Magnesium alloy and enhance its corrosion resistance, high-temperature, and room temperature strength, as well as its  elongation rate.
Q: What is Ka Shui‘s the Die Casting cum Forging Dual Forming Technology?
A: The Die Casting cum Forging Dual Forming Technology, which including 3 patents of Ka Shui, combines the Die Casting and the Forging process into one production cycle, which helps to control precisely the function, shape and size of the parts in motorcycle and automobile. This process produces better quality parts at reduced cost.
Q: What are the characteristics of of the products produced by Die Casting cum Forging Dual Forming Technology?
A: The products will have less shrinkages and porosities. They have better specific density, tensile strength and elongation rate.
Q: What are the features of Ka Shui’s Ultra-thin Zinc alloy products?
A: The Ultra-Thin Zinc alloy products of Ka Shui have better fluidity and corrosion resistance. They also consumes less material, which make them more eco-friendly when compared to ordinary Zinc alloy.
Q: Which services should be provided by Ka Shui?
A: Ka Shui provides one-stop solution from product conceptualization and design, mold design and fabrication, precision die casting, plastic injection moulding, CNC machining, surface treatment and supply chain management.
Q: What products can Ka Shui provide?
A: Ka Shui can provide Magnesium, Aluminum and Zinc alloy die casting and plastic parts for 3C (Computer, Communication, Consumer Electronics), automobile and household products.
Q: What is the concept and characteristics of pressure die casting?
A: Pressure die casting, usually referred as die casting, is a precise metal casting process by forcing molten metal under high pressure and speed into a mold cavity, then cooling it down to a specific shape. It is characterized by high injection speed ( 30~60 m/s) and pressure (70-350kg/c m2) within very short time (0.02~0.2 s).
Q: What is Squeeze Casting Technology?
A: The new type of Squeeze Casting is a die casting method based on slow laminar flow of liquid metal for continuous die filling from bottom to top, with the application of high pressure during solidification, ensuring the component is free from porosity, more compact, with good appearance and high mechanical properties. Squeeze casting technology retains the characteristics and advantages of traditional die casting in efficiency, and low cost, while able to overcome the mechanical property issues, heat treatment disability and other problems.
