Injection moulding

Metal replacement: We make some parts where a metal piece has been replaced with a plastic piece, which can result in a lighter, less material-intensive part.

High temperature materials: We also specialise in manufacturing with high-temperature materials, such as PPS, PSU, PEI and PEEK.

Foamed parts: At Bi-Plast, we mould structural foam parts using standard methods, but over the years, we have developed our own methods and know-how to mould parts with very low densities. For example, the density of PE LD and -HD is less than 0.2 g/cm3, and for ABS, PS, PP and POM, the lower limit is around 0.4-0.5 g/cm3, depending on the shape of the part.
This opens up interesting opportunities in many areas, such as replacing and improving parts that were previously made of cork, balsa wood or similar materials.

Workpieces with large and varying wall thicknesses: To counteract surface suction and prevent large voids, we use a special moulding process where the thick sections of a workpiece get small air bubbles inside their walls – but not on the surface. Parts moulded using our method, unlike structural foam parts, have surfaces that appear smooth and neat. Additionally, the resulting items are highly suitable for chrome plating, as they have only very low internal tension.

Embedding metal in plastic: If you want to avoid the need for multiple processes, you can have metal embedded in your plastic item, either by an automated or a manual process – whichever is more cost-effective.

Rubber: At Bi-Plast, you can have rubber items produced from a thermoplastic elastomer with a hardness down to 12 Shore A.
