A molding apparatus for a GRP door skin is provided. The molding apparatus is configured to form a GRP door skin of a completed product by molding a GRP door skin in a forming mold, and inserting the formed GRP door skin into a trimming removing part through a robot.

The present invention provides a method for treating a polymer workpiece for use in a joint implant. It comprises the steps of placing the polymer workpiece in an explosion chamber, introducing a combustible gas mixture into the explosion chamber and igniting the combustible gas mixture. Igniting the gas mixture in the explosion chamber produces a temperature that lies above the melting point of a polymer of the polymer workpiece.

In one embodiment of an apparatus for manufacturing a rubber sheet, a continuous rubber material is supplied onto a supply conveyor in a meandering state by supplying the continuous rubber material onto the supply conveyor while moving rubber supply device in a reciprocating manner in a roll axial direction. The rubber supply device has a full width moving mode in which the rubber supply device moves in the roll axial direction such that the continuous rubber material has a meandering shape of a width corresponding to a width of a rubber sheet, and a partial width moving mode in which the rubber supply device moves in the roll axial direction such that the continuous rubber material has a meandering shape of a width obtained by excluding widths of both edge portions of the rubber sheet from the width of the rubber sheet.

Methods for post-mold processing a Venturi device for generating vacuum are disclosed that improve the evacuation time thereof. The methods include providing a molded Venturi device having a body defining a Venturi gap between an outlet end of a converging motive passageway and an inlet end of a diverging discharge passageway, where the outlet end defines a motive exit having flash extending radially inward and the inlet end defines a discharge inlet having flash extending radially inward. Then, the method includes positioning the molded Venturi device with an inlet end of the converging motive passageway facing a blasting nozzle or with an outlet end of a diverging discharge passageway facing a blasting nozzle, and propelling blasting media into the motive inlet or the discharge exit of the Venturi device to remove the flash in the motive exit and in the discharge inlet, or vice versa.

A method of manufacturing a structure is provided in which a burr portion can be more reliably cut. In a burr portion shaping step, the burr portion is sucked to an engaging portion by a suction part to shape the burr portion along the engaging portion, and in a cutting step, ae movable portion is moved relative to first and second split molds with the burr portion being shaped along the engaging portion, thereby the burr portion is cut from a molded main body along a cutting line.

A lead frame includes an outer frame. The outer frame includes: one surface; another surface that is opposite to the one surface; a side surface between the one surface and the other surface; a recess that is formed to extend from the one surface to the side surface; and a notch step portion that is formed to extend from the other surface to the side surface.
