Monosandwich Injection Moulding

Produces parts with different skin and core materials.

The barrel of a standard injection moulding machine is filled with two types of plastic, with a different type of plastic at each end of the barrel. Both plastics are injected in one step from the barrel into a standard mould, where the first material that enters the mould forms a skin as it solidifies on contact with the mould surface. The second material follows the first; it fills the mould and forms the core of the moulded part.

Applications for monosandwich injection moulding:

The process is used to produce rigid parts with good strength combined with a soft elastomeric skin. It is used for arm rests for office chairs, chair seats, grips, and wrap-around headphones.

More information:

It is also possible to make a foamed core with a solid skin, which reduces material consumption and thereby weight and cost. The core can be made from low-cost compounds, unsightly fiber-reinforced plastic, or discoloured recycled plastic, without impairing the look of the moulded part.

Inspiration for new applications:

Use the process to produce toys with a nice soft feel.
