Vacuum molding
The vacuum molding or vacuum forming process consists of four phases: pre-heating, molding, cooling and cutting. The sheet is heated using the vacuum molding machine’s electric heater and blown into a bubble using compressed air.

The mold is guided inside the bubble, and when powerful suction (vacuum) is applied between the mold and the plastic, the plastic accurately imitates the shape of the mold. After cooling, the plastic is detached from the mold and moved on to the cutting and other finishing stages. Typical mold materials include aluminum, wood, epoxy and fiber glass.

The advantages of vacuum molding

This method can be used to produce light, impact resistant, colorful and recyclable products. Since the cost of creating molds is low, vacuum molding is a low-cost way of manufacturing plastic products.

What can we make?

Lokari specializes in manufacturing large products. The largest pieces we make are 1800 x 5500 mm in size. The maximum depth of draw is 1300 mm, although this requires the piece to have a somewhat smaller length and width.
