Sandwich moulding using the Monosandwich method

- the economical alternative in 2-component moulding

Using the Monosandwich technique, two different thermo plastics are placed within each other, creating one type of skin material and another type of core material in just one part. This enables us to produce parts with more functions and which comply with higher requirements.

Since Monosandwich parts are produced in conventional moulds for 1-component parts, large savings is an obvious additional advantage. In short, Monosandwich offers affordable, more complex parts. Naturally, we would like to assist you part design and layout. We have used this method since 1995.

 


 

Gear wheel in which the skin material has a low friction and great wear resistance
Gear wheel in which the skin material has a low friction and great wear resistance, while the core material holds stiffness and strength. Please notice that the hub has core material on the outside. The method also applies to many other types of parts.
Membrane with built-in stiffness
Membrane with "built-in" stiffness instead of metal discs on both sides.
A part with great stiffness in the middle and bearing surfaces of pure rubber on the outside
An example of a part with great stiffness in the middle and bearing surfaces of pure rubber on the outside.
Knife handle with "soft touch" and a hard core
Knife handle with "soft touch" and a hard core.
The part has soft TPU on the outside and harder TPU on the inside
Alternative would be a metal frame on the inside

The pictures show an arm rest moulded in a conventional 1-component mould using the Monosandwich method. The great wall thickness is possible due to foamed core. The part has soft TPU on the outside and harder TPU on the inside. The alternative would be a metal frame on the inside.


Arm rest moulded in a convetional 1-component mould
Another arm rest moulded in a conventional 1-component mould. It has a great wall thickness possible due to foamed core. Please notice that the white handle is pure core material.
Part with EMI-shielding material as its core
This part has EMI-shielding material as its core, covered by unfilled material to get a nice surface.
