Plastic molds components
Molds used in injection molding consist of two halves; one stationary and one movable. The stationary half is fasterned directly to the stationary plate and is in direct contract with the nozzle of the injection unit during operation. The movable half of the mold is secured to the movable platen and usually containers the ejector mechanism. There are many possible mold designs, including multiple piece molds for complicated parts. On production injection molding equipment many articles may be shot at the same time by the use of multiple cavity molds.
