A LOW-PRESSURE POWDER INJECTION MOLDING MACHINE, KIT AND METHOD

Номер: US20190134712A1
Автор: CHATELAIN Jean-François, DEMERS Vincent, G. LAMARRE Simon
Принадлежит:

A low-pressure powder injection molding machine, a kit and a method thereof. The machine has a feedstock container adapted to contain (mixed feedstock, a mold and an injection device. The mold has an inlet and a cavity in which the feedstock material can set. The injection device has an injection port for supplying the mixed feedstock from the container to the mold by using pressure. The machine also has a moveable platform adapted to provide movement between the injection port of the injection device and the inlet of the mold in order to directly communicate the feedstock between the injection port and the inlet without using an intermediate conduit and thereby preventing any feedstock from setting or dissociating between the injection port and the inlet. 1. A low-pressure powder injection molding machine comprising a feedstock container adapted to contain a mixed feedstock material , a mold having an inlet in which said feedstock material can set and an injection device having an injection port for supplying said mixed feedstock material from said container to said mold by using pressure , wherein said machine further comprises a moveable platform providing relative movement between said injection port of said injection device and said inlet of said mold so that said feedstock is communicated directly between said injection port and said inlet without an intermediary conduit.2. The low-pressure powder injection molding machine as defined in claim 1 , wherein said container comprises an outlet claim 1 , and wherein said moveable platform provides movement of said injection device between said outlet and said inlet of said mold.3. The low-pressure powder injection molding machine as defined in claim 2 , wherein said moveable platform has a flange adapted to contact the outlet and seal the outlet in order to prevent feedstock from flowing out.4. The low-pressure powder injection molding machine as defined in claim 1 , wherein said moveable platform provides a linear ...

Pulsed eddy current testing with dual-purpose coils

Номер: US20170168016A1
Автор: Florian Hardy, Marc Grenier, Maxime Rochette, Vincent Demers-Carpentier
Принадлежит: Eddyfi NDT Inc

A Pulsed Eddy Current device for inspecting an object made of an electrically conductive material comprising: at least one dual-purpose coil serving a dual purpose of producing a supplied magnetic field in the object and measuring a produced magnetic field emitted by the object, a transmitter circuit driving the dual-purpose coil(s) with an electrical signal, a shut-off current circuit for the transmitter circuit for cutting-off a current in the dual-purpose coil(s) during a cut-off phase of the electrical signal, the shut-off current circuit applying a voltage inversion on the dual-purpose coil(s) and a receiver circuit for reading the produced magnetic field from the dual-purpose coil(s). A method for inspecting an object comprising supplying a voltage on at least one dual-purpose coil, cutting-off a current in the dual-purpose coil(s) by applying a voltage inversion on the dual-purpose coil(s) and receiving, at the dual-purpose coil(s), a produced magnetic field.
