Types of Injection Molds for Injection Molding Process

1. Types of Injection Molds for Injection Molding Process Different types of injection molds are designed based on the specification of manufacturing plastic product. It is selected for a particular injection molding process depending on the tooling insert design, production volume, and the budget. The kind of injection mold selected for a specific product manufacturing affects its quality and manufacturing cost. Various types of injection molds are listed below which are classified on the basis of feeding system, number of cavities, and mold opening. On The Basis Of Feeding System Hot runner injection mold- It consists of two plates and the runners are heated to keep the raw plastic material in molten state. These runners deliver the molten plastic to the nozzle part. Since, the runners are not attached with the molded parts, the material cost and cycle time highly reduced. Hot runner mold system is usually recommended for production of larger components. This mold type is not suitable for thermal sensitive material. Cold runner injection mold- It consist of either two plate or three plate injection molds, the runner system is not heated up and ejected along with molded component unlike hot runner system. The maintenance and operational cost of cold runner molds are low. Setup is simple and change of color and material is also easy. On the basis of cavity numbers Single cavity- This type of mold is used for low production rates as only a single part is manufactured per cycle. It offers flexibility in terms of injection molding process control. Though the initial investment is lower but cost per unit can go higher. Multi-cavity- This type of mold produces large number of parts per cycle, hence the production rate is also higher. Cost of multicavity mold is also high as compared to single cavity. Check out multicavity cap tooling. Family mold- This type of mold produces two or more components per cycle. As different parts are can be produced in single cycle the overall cost reduces highly. It lacks variety.

2. On the basis of mold opening Two plate mold- These molds are least expensive to manufacture and require both type of runner system. Three plate mold- These molds allow speedy production with less or no manual labor. Only cold runner is required. So, you need to select the injection mold depending on the geometry, required production rate, quality and budget.
