Basic Information

Injection molding is the primary process for manufacturing plastic parts. Plastic is known to be a very versaltile and economical material that is used in many applications. Although the tooling is expensive, the cost per part is very low.

Injection molding involves taking plastic of your choice in the form of pellets or granules and heating this material until a melt is obtained. Then the melt is forced into a split-die chamber/mold where it is allowed to "cool" into the desired shape. The mold is then opened and the part is ejected, at which time the cycle is repeated again.
