Some plastic products are made with the supporting part in which its absence will be an incomplete product. Such part is said to be ‘cap’. The products such as storage bottles, storage containers and writing pens, etc. has the use of caps. The dimensions of the cap vary with the product design and its utilization. The strength of the cap is normally tough, so high density plastic is used for molding. The cap molding machine, we produce has high quality molds and the reciprocating screws made of stainless steel alloys to avoid corrosion and embedding of molten plastics. To produce the plastic caps, the plastic granules are compressed by the reciprocating screw and it is heated up to transform to the molten stage. The reciprocating screw is driven by the electrical drives and it pushes the molten plastic towards the nozzle.Our machine’s nozzle has the peculiar design to create pressure when the plastic is injected into the mold. The cap molding machine can be of multiple cavity mold or multi cavity with different dimensions in the mold. The molding process involves two molds, the stationary mold and the movable mold. Both the molds are fitted to their respective supporting plates. The movable supporting plate has ejecting pins to eject the products out of the mold after cooling the molded plastic.
The clamping system is fitted to the movable supporting plate to compress the molds for the molding process. We use hydraulic clamping as it was well effective and has high performance for fast processing. The pressure applied by the reciprocating screw should be optimized to avoid product defects like flash defect that occurs over pressure and shot defect due to improper flow of molten plastic into the cavities. After some cycle of the process, the molds are to be cleaned and maintained to maintain the quality of the product. We promise you that our molding machines are best in performance and makes no chance no production loss.
