Process for obtaining a thermoplastic material product, and the corresponding product

摘要

The invention relates to a process for the manufacture of thermoplastic resin parts, comprising the steps of:
a) introducing a thermoplastic material (2) in a cavity (11) of a mold (1);b) closing the mold (1), compressing and distributing the thermoplastic material (2);c) opening the mold (1) and removing the obtained product.
Step a) comprises the steps ofa1) depositing the thermoplastic material (2) on a carrier support (4);a2) moving the carrier support towards the cavity of the mold;a3) depositing the thermoplastic material (2) inside the cavity of the mold.

主权项

1. A process for manufacture of thermoplastic resin parts, comprising the steps of:
a) introducing a thermoplastic material comprising at least one thermoplastic resin in a cavity of a mold; b) closing the mold, compressing and distributing the thermoplastic material inside the cavity of the mold; c) opening the mold and removing a product, obtained from said thermoplastic material, from the cavity of the mold; wherein step a) comprises:
a1) depositing the thermoplastic material in a softened state on a carrier support, such that the thermoplastic material is distributed on the carrier support in a pattern corresponding to a layout of the product of step c), wherein said pattern is determined by a relative movement between the carrier support and a dispensing member from which the thermal plastic material is deposited;a2) moving the carrier support, with the thermoplastic material, towards the cavity of the mold and introducing said carrier support inside the cavity of the mold;a3) depositing the thermoplastic material by gravity inside the cavity of the mold; wherein said carrier support is a tray, a box or a container.
