A machine including a mold which delimits an overmolding cavity, for receiving a hollow portion of a bi-material part, cooling means along the overmolding cavity, a core positionable inside the hollow portion and containing heating means for bringing the core to a heating temperature higher than 150° C., and an injector injecting an overmolding material, formed by the core and the hollow portion, for forming an inner portion of the bi-material part. In order to obtain the overmolded inner portion even if the hollow portion has poor heat resistance, the cooling means maintain the overmolding cavity at a cooling temperature lower than 110° C. while the core is brought to the heating temperature, while the overmolding material has been injected by the injector into the overmolding cavity.

An insert molding apparatus includes: a lower mold including a seating part on which an insert member including a through-hole is seated; an upper mold mounted on the lower mold to receive the insert member seated on the seating part; and a first fixing part including a first head provided in the lower mold and inserted into the through-hole of the insert member when the insert member is seated, and a first drive unit that moves the first head. The first drive unit is moved to adjust a length by which the first head is inserted into the through-hole.

A method for providing accessories for washbasins and sinks in general, particularly of the type of covers and shelves, that includes the following steps: providing a first mold part which reproduces in negative form the visible surfaces of at least one accessory; providing a second mold part which reproduces in negative form the hidden surfaces of the accessory; mating the first mold part with the second mold part; and injecting material in the melted state into the cavity defined between the first mold part and the second mold part. The method also includes the steps of solidifying the material, and opening the first mold part and the second mold part, with consequent extraction of the at least one accessory.

A tool for driving a threaded fastener includes a driver head, a motor, and an injector. The driver head includes a spindle rotatable about an axis. A distal end of the spindle defines a plurality of drive surfaces configured to engage mating drive surfaces on the fastener to rotate the fastener about the axis. The driver head defines a fluid passage having an outlet proximate to the distal end of the spindle. The motor is drivingly coupled to the spindle to rotate the spindle about the axis. The injector is coupled to an inlet of the fluid passage and configured to feed a liquid insulator through the fluid passage.

When an exterior portion is provided on an exterior surface of an extrusion-molded portion of a sealing member having the extrusion-molded portion and a mold-formed portion, while appearance is made favorable, the exterior portion is inhibited from being damaged. A glass run 20 includes an upper glass run edge 20a which is extrusion-molded, a rear connecting part 20f which is molded integrally with one end portion of the upper glass run edge 20a, and an exterior portion 29 provided on an exterior surface of the upper glass run edge 20a. A surface Si of the rear connecting part 20g on an outside of a passenger compartment is located further outside than a surface of the exterior portion.

An object of the present invention is to suppress an outflow of varnish from a lower portion of a stator core by increasing a filling rate of varnish in a slot. Provided is a method for manufacturing a stator of a rotary electric machine. The stator has a coil and a stator core in which a slot that houses the coil is formed, and a resin member of which viscosity is low at a first temperature and the viscosity is high at a second temperature higher than the first temperature is filled in the slot from an injection side. The manufacturing method includes a first step of causing a temperature difference in the stator core such that the injection side becomes the first temperature and an opposite side of the injection side becomes the second temperature, and a second step of injecting the resin member from the injection side in a state in which the temperature difference is maintained.

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.
