Molded Parts

Molded parts is the most efficient method of mass producing plastic parts. This allows you to deliver parts faster and more cost-effectively than other methods. If you don't know the best practices, designing parts for molded parts can be difficult.

The molded parts process

Injection molding is a mass production process that makes many identical parts quickly using moulds.

Plastic pellets are used to produce parts by injection molding. They are fed through a chute into a barrel using a hopper. The pellets are then pushed towards the barrel's heated end by a plunger and screw mechanism, where they melt. After the pellets have melted the liquid plastic flows through the barrel's end nozzles into a mould cavity. The mould can be quickly cooled and dried using water cooling channels. This allows the plastic to retain its original shape. The ejector is used to push the part out of its cavity. The mould is then closed again to make it ready for the next injection. This is called a mould cycle. The mould cycle can take between two and five seconds depending on the material, design, and size of the part.

Although injection molding is simple, it is only as effective as the part that is being made. It is important to understand injection molding best practices and design parts with care in order to achieve the quality you desire. Poor part design can cause serious problems like sinking, warping, or hollowing. If your part design is not easily removed from the mould, it could cause damage to the part and the mould. This can lead to costly repairs and countless hours of work.
