To provide a method for readily forming an easily separable portion having an adhesive strength that is required as a package bag on packaging film, a package bag having an easily separable portion formed by this method, and a filling-packing machine utilizing this method. A method forming an easily separable portion in packaging film by interposing at least two packaging films between a horn emitting ultrasonic waves and an anvil oppositely disposed to the horn, and vibrating the packaging films by the ultrasonic waves, in which a vibratable layer is provided on the packaging film in at least one of the horn side and the anvil side.

In one embodiment, an additive manufacturing method including the steps of positioning a removable surface on a worktable; applying an adhesive material to the removable surface; depositing a plurality of pellets into the adhesive material, wherein at least a portion of each pellet of the plurality of pellets remains exposed; depositing a first plurality of layers of a flowable material on at least some of the plurality of pellets; and depositing a second plurality of layers of the flowable material on the first plurality of layers.

Systems and methods for forming 3D plastic parts that are cost effective in low volume, have excellent fit and finish, and use many components from 2D construction are disclosed. The systems and methods involve selecting a design and modelling the design. The design comprises 2D and 3D components of plastic parts. A 3D forming buck corresponding to the 3D component is manufactured. At least one of a 2D part and the 3D forming buck may be heated. The 2D part may be loaded onto the 3D forming buck for a predefined period of time. The 3D part formed after the loading may be separated from the 3D forming buck. The 3D part is the 2D part generally having taken the shape of the 3D forming buck. The 3D part may be cooled to obtain an end product.

Method for manufacturing a wood composite, comprising the steps of providing an reactive composite mixture (4) by mixing a reactive binder and vegetable fibres; supplying the reactive composite mixture to an extruder (5), discharging of the composite mixture from the extrusion device via an extrusion discharge (6) to a curing mould (8); filling the pores of the vegetable fibres with the reactive binder while simultaneously expensing the air from the pores at extrusion process conditions; reacting of the reactive binder around the vegetable fibres and in the pores of the vegetable fibres into a wood composite at the temperature of the extrusion process conditions.

The present invention relates to a thermoforming mold for EVA, comprising an upper aluminum mold and a lower aluminum mold, both of which are hinged and each provided with a handle, wherein, the upper aluminum mold is provided with a raised pattern, and the lower aluminum mold is provided with a sunken cavity, characterized in that an upper passage passing through the inside of the pattern is provided inside the upper aluminum mold, a lower passage passing through the bottom of the cavity is provided inside the lower aluminum mold, the upper passage has a first opening in the inner surface of the upper aluminum mold, the lower passage has a second opening corresponding to and communicated with the first opening in the inner surface of the lower aluminum mold, and both sides of the lower passage are provided with a vapor/water inlet and a vapor/water outlet respectively.

A template made of plywood or similar material is inserted into a cover for a protective helmet so that the cover is stretched and once the template is inserted the assembled combination of the cover and the template resembles the shape of a disk. The disk-shaped assembly is placed on top of the bottom plate of a heat press. A layer with a decal or sticker is placed on top of the disk-shaped assembly. A heat press cover sheet is then placed on top of the disk-shaped assembly so that it also becomes into contact with the top plate of the heat press when the heat press is closed. The heat press may be set to a temperature of 350 degrees Fahrenheit and it can be set in a closed position for about 30 seconds in order to transfer sufficient heat so that the decal or sticker is applied or affixed to the cover surface.

A vacuuming forming method for creating an embellished reproduction of an image. The image is printed on to a thermoformable substrate to create a printed substrate. A chemical compound is applied to a surface of a perforated sheet to form artistic embellishments on the surface and create an embellished sheet. The printed substrate is positioned over the embellished sheet placed on a vacuum table. Heat is applied to the printed substrate and sufficient vacuum is provided to the vacuum table to press the printed substrate on to the embellished sheet to form an embellished reproduction of the image from the printed substrate. The perforated sheet can have a three-dimensional surface, which can be included in the embellished reproduction.
