B29C44/04 - CPC Classification

Classification description:

Shaping by internal pressure generated in the material, e.g. swelling or foaming ; Producing porous or cellular expanded plastics articles for articles of definite length, i.e. discrete articles consisting of at least two parts of chemically or physically different materials, e.g. having different densities

Sub-classes:

B29C44/0407 » {by regulating the temperature of the mould or parts thereof, e.g. cold mould walls inhibiting foaming of an outer layer} 47
B29C44/0415 » {by regulating the pressure of the material during or after filling of the mould, e.g. by local venting} 56
B29C44/0423 » {by density separation} 3
B29C44/0446 » {by increasing the density locally by compressing part of the foam while still in the mould} 22
B29C44/0453 » {by joining the different materials using compression moulding before the foaming step} 1
B29C44/0461 » {by having different chemical compositions in different places, e.g. having different concentrations of foaming agent, feeding one composition after the other} 123
B29C44/0484 » {by having different solubility of the foaming agent} 8
B29C44/0492 » {Devices for feeding the different materials} 12
B29C44/06 » Making multilayered articles 154
