    What is the Difference between Die Casting and CNC Machining?

    Die casting and CNC machining are two of the most popular industrial processes for producing metal parts. Both of them can be combined for the best possible finish. However, when it comes to choosing one process over the other, there are some important factors to consider. Die casting involves melting metal and injecting it into a steel mould (die casting mould). The metal is then c...

    What is the Difference between Die Casting and Injection Molding?

    When considering which manufacturing method is best for your application or components, two of the most popular processes include die casting and injection molding. The process of injection molding and die casting is similar, the main difference is the material used. And they have their own advantages and disadvantages. Which one to choose? If you have determined which kind of material to use, the...

    What are the steps of high-pressure die casting?

    High-pressure die casting is a metal casting process that involves injecting molten metal — zinc, aluminum, magnesium, etc. — into a three-dimensional mould. The base metal is heated until it achieves a liquid, molten state. It’s then forced into the mould’s cavity, allowing it to take the shape of the mold once cooled. High-pressure die casting is used to create everything from engine b...

    How long does an injection mold last?

    When you are purchasing plastic injection molds, you'll have noticed that many mold makers guarantee the lifetime for the molds they build, such as 300,000 shots, 500,000 shots etc. Mold life means the life of the mold, not yours. Injection mold life stands for the number of molding cycles that a mold can make before it needs to be replaced. How long does a plastic injection mold last? Any injecti...

    Is 3D printing cheaper than injection molding?

    3D printing and plastic injection molding are both helpful processes in their own right. 3D printing has given engineers the power to create plastic designs at their desks and bring them to life in a matter of hours. Injection molding, on the other hand, is the go-to for quality and value. It is commonly used to quickly and reliably produce high-volume runs of complex plastic designs. Both of...

    What is plastic injection moulding process?

    Plastic injection moulding is a manufacturing process for producing parts by injecting molten material (resin) into a mould. Material for the part is fed into a heated barrel, mixed (using a helical screw), and injected into a mould cavity, where it cools and hardens to the configuration of the cavity.  After a product is designed, usually by an industrial designer or an&n...
