Foaming Process

Venting tape covers holes to prevent the PU foam from squeezing out during injection while still allowing air flow.

Covering all gaps and joints prevents the PU foam from squeezing out during injection. Cloth-based tapes fit the contours of small corners best.

Holding the form together tightly where two parts (for example, PS body and metal housing) are joined prevents damage to the PU foam during injection.

Covering holes as well as gaps in a PS body or door prevents the PU foam from squeezing out during injection.
