As a specialist in polyurethane molded parts, Emaform AG supports you from product development to series production. Our customer service team assists you with the design of PUR housings, material selection, and the economic optimization of your technical molded parts. With decades of experience in the polyurethane sector, we find tailor-made solutions for your individual requirements, from prototypes to series production.
With integral rigid foam, wall thicknesses can vary greatly (there are hardly any depressions on the surface).
With compact material, wall thicknesses that are as uniform as possible are advantageous.
For both materials, it should be noted that different wall thicknesses can lead to warping (due to uneven shrinkage) of the molded parts.
The size, geometry, and application of the molded part essentially determine the wall thickness.

Ribs with a thickness of ± 50% of the wall thickness can be used to achieve optimum stability of the molded parts without causing sink marks on the visible sides. Where possible, the rib position should correspond to the foaming direction in order to avoid air pockets.

Brass threaded inserts are most commonly cast in (various products, usually manufacturer-specific).
When inserting metal parts for reinforcement, care must be taken to ensure that no unacceptable distortion of the molded parts occurs and that no stresses arise that could cause damage.
