Mold Manufacturing for Different Molding Processes

[martinherb563]

The plastic injection molding process can be adjusted to accommodate different and complex needs. While it is ideal for manufacturing large volumes of simple plastic parts, it can also be used to create incredibly intricate parts with complex geometries or assemblies.

Multi-Cavity or Family Mold – This mold has multiple cavities in a single mold frame that produce several of the same or related parts with each injection cycle. This is an ideal way to increase run volumes and lower the per-piece-price.
Overmolding – This injection molding method is used to create parts made with two different types of plastic. A good example of this would be a portable drill body or game controller with a hard outer shell with soft, rubberized grips. A previously molded part is re-inserted into a specially made mold. The mold is closed and a second layer of different plastic is added over the original part. This is an ideal process when two different textures are desired.
Insert Molding – An injection molding process that allows for the incorporation of metal, ceramic, or plastic pieces into the final part. The metal or ceramic parts are placed in the mold and then melted plastic is injected into the mold to create a seamless piece made of two different materials. Insert molding is ideal for automotive applications as it is an innovative way to reduce weight and reduce costly material like metal. Instead of making the entire piece out of metal, only the connecting pieces need to be metal while the rest of the item will be made out of plastic.
Co-Injection Molding – Two different polymers are sequentially or concurrently injected into a cavity. This process can be used to create parts with a skin of one kind of plastic with the core of another.
Thin-Wall Molding – A form of injection molding that focuses on shorter cycle times and higher productivity to produce thin, light, and cheap plastic parts.
Rubber Injection – Rubber is injected into a mold using a process similar to plastic injection molding. Rubber parts require more pressure for successful injection molding.
Ceramic Injection – Injection molding process utilizing ceramic material. Ceramic is a naturally hard, chemically inert material that is used in a variety of industries. Ceramic injection requires several extra steps; including sintering or curing the newly molded parts to ensure the characteristic durability.
Low-Pressure Plastic Injection Molding – Plastic parts that are produced at lower pressures. This is particularly useful for jobs that require an encapsulation of delicate parts, such as electronics.
