Abstract
A method for reaction injection molding of a structured component is disclosed. The method includes (i) closing a mold in order to provide a cavity adapted to form the component, wherein the mold includes a negative shape of the component, (ii) injecting a reaction injection molding resin at a low packing pressure into the cavity in order to fill the cavity, (iii) curing the reaction injection molding resin in the cavity using UV-light through a transparency in the mold, (iv) opening the mold, and (v) demolding the cured component. Also, a corresponding component, apparatus and system are disclosed.
Claims11
A method for reaction injection molding of a structured component, comprising:
- closing a mold in order to provide a cavity configured to form the component, wherein the mold comprises a negative shape of the component;
- injecting a reaction injection molding resin at a low packing pressure into the cavity in order to fill the cavity;
- curing the reaction injection molding resin in the cavity using UV-light through a transparency in the mold;
- opening the mold;
- and
- demolding the cured component.
An apparatus for reaction injection molding of a structured component, wherein the apparatus comprises a first mold part and a second mold part which are configured, in a closed configuration, to form a mold that contains a cavity configured to form the component, the mold comprising an injection port configured to receive a UV-curable reaction injection molding resin at a low packing pressure to fill the cavity, wherein at least one of the first and second mold parts is configured to provide a transparency adapted to allow for curing the reaction injection molding resin inside the mold using UV-light, wherein the first mold part and the second mold part, in the closed configuration, are held together by a clamping device.
