注塑机具有能一次成型外型复杂、尺寸精确或带有金属嵌件的质地密致的塑料制品的能力，被广泛应用于国防、机电、汽车、交通运输、建材、包装、农业、文教卫生及人们日常生活各个领域。优点： 1. 因原料大都為預行壓製，體積小且密實，因此，裝料及加熱時間短。 2. 原料為熱固性塑膠，一經聚合即不再軟化，可不必等到模子冷卻，即可脫模，節省整體工作時間。 3. 進入模穴的材料為液體或可塑性極高的近似液體，所需壓力不必太大。
What is Plastic injection molding do?
Plastic injection molding is known as the most common and most efficient form of molding. The process itself is extremely fast compared to other methods, and the high production output rate makes it even more efficient and cost-effective.
Speed depends on the complexity and size of the mold but only about 15-120 seconds pass between each cycle time. With the short period between cycles, a greater quantity of molds can be produced in a limited amount of time, thus increasing possible revenue and profit margins. At Rodon, we run parts 24/7 using an MRP system (Material Requirement Planning System).
