Types of Moulding

dip moulding

Dip Moulding

The Dip Moulding process involves dipping a preheated mandrel into plastisol, followed by a high temperature cure. The cured plastisol is then removed from the mandrel resulting in a finished part. This part can be further enhanced by a variety of secondary operations including printing, hole punching, trimming and assembly. Parts that are too large for dip coating, too costly to ship, or that require a removable protective covering, are excellent candidates for dip moulding. Also, parts whose volume does not justify the tooling costs associated with injection moulding are ideal for dip moulding.

vacuum forming

Vacuum Forming

Vacuum forming is a plastic thermoforming process that involves forming thermoplastic sheets into three-dimensional shapes through the application of heat and pressure. In general terms, vacuum forming refers to all sheet forming methods, including drape forming, which is one of the most popular. Basically during vacuum forming processes, plastic material is heated until it becomes pliable, and then it is placed over a mold and drawn in by a vacuum until it takes on the desired shape. Vacuum thermoforming is a great method for producing plastic parts that have sharp details and fit nicely to specific products.
