Description
Short running injection molding is widely used for the prototype, R&D development of products. How to reduce the short running injection cost is considered mostly by the plastic mold manufacturer and pastic molding company as well customers.Nodinson is expert to make injection mold for plastic parts with various ribs especially for short run injection molding plastic parts. Ribs are good solution to increase the strength of molded parts in condition of keep even wall thickness. Ribs are problem to eject parts from mold in plastic molding process. The ribs with longer length and higher height are war page after injection molding. It is great chanellenge to keep them straight. Therefore it is tough for plastic mold manufacturer for mold making of parts with varous ribs. The engineers check the draft angles, length, height of ribs if they are free for ejection. Then engineers consider mold design and mold making for the ribs. They consider to cut ribs directly in solid steel or make mold inserts for them. Cutting ribs in solid steel is most economic solution for ribs if the ribs can be polished and machined with CNC machining or EDM machining. Ohterwise they will make inserts for ribs. It will be easy to machine them and polish them. The inserts are very small. It will be a problem for cooling system. Sometimes the mold maker will be use Beryllium Copper to make mold inserts instead of steel which have better cooling function.
