A sample cell (10) for a respired gas sensor has a single-piece injection molded main body (40) defining a gas flow path including an optical sampling bore (42), a gas inlet lumen (50) connected with the inlet end (44) of the optical sampling bore, and a gas outlet lumen (52) connected with the outlet end (46) of the optical sampling bore. The gas flow path includes at least two curved walls (100, 102, 104, 106). The sample cell may be manufactured by assembling mold pins (120, 122, 124, 126, 128) for defining the gas flow path wherein at least two mold pins (122, 124) have curved surfaces for defining the at least two curved walls of the gas flow path, and injection molding the single piece injection molded main body including removing the mold pins after defining the gas flow path including the at least two curved walls.

A molded plastic article having a bonded plastic portion 6 bonding a first body and a second body together; a connecting plastic portion 8, formed by solidifying the molten plastic flowing out from the plastic channel, having one end connected to the bonding plastic portion 6; and a flow tab plastic portion 7 formed by solidifying the molten plastic, connected to the other end of the connecting plastic portion 8 connected to the other end portion of the 8. A portion of reduced diameter 7a is provided to the flow tab plastic portion 7 on the connecting plastic portion side.

A method including a first step of performing clamping of a mold, injection and dwelling in an injection molding machine, a second step of performing a conveyance and a cooling of the mold outside of the machine, and a third step of performing a conveyance of the mold into the machine, an opening of the mold and an ejection of a molded part in the machine. The second step is performed for a first mold, the third step and the next first step are performed for a second mold. The first mold is conveyed by a first conveyance apparatus which is arranged on one lateral side of the machine. The second mold is conveyed by a second conveyance apparatus which is arranged on the other lateral side and is independently driven from the first conveyance apparatus.

The present invention relates to an injection moulding system for forming an oven liner, particularly of the type that is used with microwave ovens. Oven liners are of particular benefit when used inside microwave ovens. They improve hygiene as where food spills or spurts onto the oven liner rather than an interior of the microwave oven. An injection moulding system for forming an oven liner includes: a first mould tool which defines a cavity of length (L), width (W) and height (H), the first mould tool has a substantially rectangular end face with dimensions corresponding to the width (W) and height (H) of the cavity and has a hot feed located at a centroid of its end face; and a wedge collapsing tool is received in the cavity so as to contact and engage with an external periphery of the first mould tool at selected locations in order to define a volume into which hot material feed is injected, wherein the wedge collapsing tool comprises a first part and a second part in slidable contact one with another, and the width (W2) of the second part exceeds the width (W1) of the first part of the wedge collapsing tool by at least 0.1 mm so that a split line is formed on at least one side of an interior surface of the oven liner.
