The object of the present invention consists of a device that allows for the easy creation of 2-dimantional and 3-dimensional plastic objects using a 3-D drawing pen. The device object of the present invention is comprised of a flexible, heat resistant, non-sticky, transparent silicon mat characterized by the presence of grooves cut in its surface, the path of which can be of any geometric or non-geometric shape. The groove works as a guide for the 3-D drawing pen user by allowing such user to stretch the melted plastic, extruded by the 3D pen, on its bed, and within its walls, so that once hard the plastic object is exactly of the shape of the groove and its path, and not an imprecise shape caused by the unstableness of the hand of the free-hand 3-D pen user.

A method of fabricating a composite structure includes laying at least one composite ply about a bladder, the bladder comprising a phase change material in a first phase having a first volume, positioning an outer mold about the bladder and the at least one composite ply, and curing the at least one composite ply to form the composite structure. Curing causes the phase change material contained within the bladder to change to a second phase to expand from the first volume to a second volume and apply a pressure to an interior surface of the composite ply and press an outer surface of the composite ply against the outer mold to form an interior cavity. The bladder is not removable from the formed interior cavity.

The present invention relates to an adjustable polymeric pipe flashing system (also known as a “pipe boot” or “geomembrane boot”) that allows for angle adjustability without the need for assembly aids. The polymeric pipe flashing system is made of a single piece using methods known in the art such as, without limitation, vacuum molding. The pipe flashing system comprises a sleeve with one or more disk-like elements having different diameters to accommodate a variety pipes, a flexible skirt and free-field geomembrane base. The sleeve may be adjusted to accommodate the size of the pipe that is to be rendered leak-resistant. The flexible skirt and free-field geomembrane base are pliable and may be adjusted over an angled pipe without breaking. In one embodiment, the pipe flashing system has sufficient flexibility to be used with pipes having a pitch of approximately 3/1.

An equal-fork pallet comprising a pallet body is provided. The pallet body is provided with a stand structure and a reinforcing structure, the reinforcing structure is a reinforcing rib embodied by a groove structure pressed on the surface of the pallet body, and the reinforcing rib comprises a connection type reinforcing rib and a semi-partition type reinforcing rib, the stand structure comprises a corner stand, an edge stand and a center stand, and neither end of the partition type reinforcing rib is connected to the stand. The equal-fork pallet has a reasonable structural design and strong pressure bearing capacity, with targeted layout and design of the reinforcing rib centralized position and stress concentration position such as stand. The pallet can overcome the problems of low local compressive strength and proneness to produce stress fracture and local cracking.

A method of manufacturing a midsole includes placing first and second preforms into a midsole recess of a mold, with first and second portions of the mold defining a first overflow chamber connected to the first recess; closing the mold by positioning the first and second portions in contact with one another; heating the mold for a predetermined period of time at a predetermined temperature such that the first and second preforms melt and bond together to form a midsole, with a portion of each of the first and second preforms flowing into the first overflow chamber to form a first overflow portion; removing the midsole from the mold; allowing the midsole to expand; and cutting away the first overflow portion.

A method of forming a bi-injected closure, comprising the steps of: forming a cap with a top plate and a depending sidewall, in a first injection moulding phase using a first mould part, the cap formed so as to include one or more external sealing areas; changing the first mould part for a second mould part, the second mould part sealing against the or each sealing area on the cap; and forming an outer ring around the cap sidewall whilst the second mould part is sealed against the sealing area/s in a second moulding phase.

This invention concerns a process for producing particle foam part in which foam particles are heated in a molding tool so that they weld to the particle foam part. Heat is supplied to the foam particles by means of electromagnetic RF radiation. The foam particles are made of polyurethane (PU), polylactate (PLA), polyethylene block amide (PEBA) or polyethylene terephthalate (PET).

The invention relates to a method and a device for producing a particle foam part. The device comprises a molding tool (3) which delimits a molding chamber (14), wherein at least two capacitor plates (15, 16) are arranged adjacently to the molding chamber, said plates be connected to an RF radiation source. The RF radiation source is designed to dispense RF radiation, and the molding tool (3) has means for controlling the temperature of the molding tool in the region of an inner delimiting surface (19) delimiting the molding chamber (14) and/or for supplying a heating medium to the molding tool region lying against the inner delimiting surface.
