The injection molding is a process to form the plastic resin into the desired shape. Injection molding machine press the melted plastic into the mold, and cool down by cooling system into solid designed shape, almost all thermoplastics using this method, comparing with other processing way, injection molding has advantage of accuracy, productivity, it has higher requirement for equipment and

Foundry crane is one of the key equipment in the steelmaking process, applicable to metal smelting workshops to lift and move hot molten metal. Foundry overhead cranes work in harsh environments with high temperature, high dust and harmful gases, and are generally suitable for ambient temperatures of -10 °C to + 50 °C.
Clamping force to hold mold closed: F = Z A P∗dA = 2πP∗ Z R 0 rdr = πR2P∗ General Result F = P∗A Example: Typical packing pressure P∗ = 108 Pa for a total area of A = 0.1 m2. Clamp force F = P∗A = 107 Nt= 1000 tons. This is why injection molding machines are soPerfect. They have to keep the mold closed! 11

greater. While a job shop may produce 5 to 10,000 tons of castings a year, work with several thousands casting designs, and with a majority of orders below 100 pieces, a production foundry might produce 50,000 tons a year with only a few hundred patterns. Layouts and descriptions of representative jobbing and production foundries are presented in
7.6.1 Mold categories. Casting processes are often subdivided into “expendable mold” and “permanent mold” processes, based upon the ability of a mold to be reused. With expendable molds, the mold is used only once; following casting and solidification, the mold is usually destroyed to remove the solidified casting.
This is due to the size limitations of injection mold machines and the mold tools themselves. For an example of aPerfect injection molded part, consider the shopping carts at Target. Although the machinery exists to mold veryPerfect pieces (e.g. 1000 ton presses roughly the size of a train’s caboose), using it is very expensive.
