How Does Three Plate Injection Mold Work Three Plate Injection Mold is a common injection mold ,it consists three parts: Fixed Half, Moved Half, Runner Plate.  Three Plate Molding Process is completed by two times of closing and opening  when injecting.  When opening, runner plate is first time, then moved half is second; When closing, Moved half is first time, runner Plate is second. The following is the main working principle: ⇒Mold Closed: At the begining of the injection cycle, the moved and fixed half will be retatively closed ,sealing the mold of cavity and core a closed space ⇒Plastic Injection: After mold is closed, the melted plastic is injected into the nozzle of the injection machine, and the melted plastic is injected into the mold cavity through high pressure ⇒Plastic Filling: Injection machine inject molten plastic into the mold, filling the ful space of mold cavity. Plastic cools and solidifies in the mold, gradually forming the shape of plastic products ⇒Cooling: After the completion of plastic filling, the cooling system starts to work, and the cooling and solidification process of the platic is accelerated by circulating the cooling medium ( normally water) ⇒Mold Opened: When plastic is fully cooled and solidified, the moved and fixed half will separate and open, part is enjected from the mold   Main Type of Gating For Two Plate Mold   Side Gating Direct Gating Sub Gating Banana Gating   What's  the  Advantage of Three Plate Mold   Simple Structure:Two plate injection mold is composed of two halves，with only one movable half between fixed and removed half. The structure is simple and clear,making it easy to maintain and operate   High Space Utilization: The fixed and moved half  of the two plate injection mold is vertical separation. Compared with the injection mold construction with  other structures, the two plate injection mold is more compact in size and more efficient in space utilization.   Wide Application : Two Plate injection mold is suitable for situations when injection molded parts are relatively simple and small mass production. Specific application areas include electronic products, plastic parts, daily necessities,etc   Easy Ejection: Due to the large opening and convenient opening-closing , the ejection speed of the two plate injection mold during the injection molding process will be faster, which is beneficial for improving production efficiency.

It is only for pin-pointing gating Six main Systems of Plastic Injection Mold Running System : The Flow Running before plastic enters the mold from the nozzle, including Sprue，Main runner,  Branch runner,Slag Well,Gate.             Form System: The system refers to various combinations of parts that form the shape of a product, including moved mold (Core side) and fixed mold (Cavity side). The moved mold forms the inner surface of the product, the fixed forms the outer surface shape of the product.According to process and manufacturing requirements, Sometimes, the core and cavity inserts are composed of severial assembly parts,  Sometimes inserts that made into a whole that are easily damaged and difficlut to machine. Cooling System:  Cooling system is required to meet the temperature requirements of the injection process for the mold, and it is necessary to have a cooling system to adjust the temperature of the mold.  The common method of mold cooling is to set up a cooling water channel inside the mold, which uses the circulating cooling water to carry away the heat of the mold; The heating of the mold can not only utilize cooling water to pass through hot water or oil, but also install electric heating elements inside and around the mold Exhaust System: Exhaust system is set up to exhaust the air in the injection molding process and the gas generated by the melting of plastic into the mold. When the exhaust in not smooth, the surface of the product will form air marks,charring and other defects. The exhaust system of plastic mold is usually a slot shaped air outlet that set up in the mold to exhaust the air in the original mold and the gas brought in by the molten material. Guidance System: Guidance System is established to ensure accurate alignment between the moved and fixed half during mold closing,four sets of guide pin and guide bush are usually used to form the guiding components. Sometimes, it is necessary to set up mutually matched inner and outer conical surfaces on the moved and fixed half to assist in position.   Ejection System: After the product is formed and cooled in the mold, when mold is opened, the ejection mechanism (ejection pin) is pushed by the ejector pin of the injection machine, then the product and runner system is pushed from the core side, in order to proceed with the next molding cycle. Ejection System generally consists of several parts: Ejection Pin, Ejection Sleeve,Ejection Plate,Ejection Guide Pin and Return Springs        Main Types of Injection Mold From Wiesel Singel Mold: Only one cavity for part, it is good for small order      Family Mold: Many parts are in one  mold, it is good for many similar parts of small order Overmold: the mold is good for different color and material in part. Insert Mold: Mold is for plastic with metal, normally, the material of metal is steel, brass,etc.   Why Choose Wiesel for Plastic injection Mold Manufacturing   Accessible  Communication We have experienced project managers and multilingual salesman for your projects.
