Molded plastic structures

A structure, such as a tabletop, may be constructed from blow-molded plastic. The tabletop may include an upper surface, a lower surface, and a hollow interior portion disposed between the upper surface and the lower surface. A lip may extend downwardly relative to the lower surface of the tabletop, and the lip including an outer surface and an inner surface. One or more supports may be disposed in the inner surface of the lip, and one or more joints may be disposed in the inner surface of the lip. A joint may be disposed between adjacent supports, and a distal portion of the lip may include a compression edge. A lower portion of the supports may contact the compression edge, and/or a lower portion of the joints may contact the compression edge.

An indoor livestock confinement system includes a plurality of hollow plastic panels. One of the hollow plastic panels defines a U-shaped door frame. The door frame is open at the top and includes an attachment for a door at one edge. The door frame includes a reinforcement inside the panel that extends across a bottom threshold and sides of the door frame.

Hinge mechanism

A hinge mechanism includes a resin base member, and a support rotatably and pivotally mounted to the base member. The base member is formed by blow molding so as to be hollowed. The base member integrally includes a hinge member for rotatably and pivotally mounting the support to the base member. The hinge member is set in a molding die for clamping at the time of the blow molding of the base member, so as to be molded integrally with the base member.

A plastic molded lip structure may extend along a perimeter of a planar element and may include an outer wall, an inner wall, structural portions, and protruded features. The outer wall may extend in a normal direction from the planar element. The inner wall may be disposed in an inward direction relative to the outer wall. The structural portions may be disposed along structural sections of the perimeter and may include first portions of the inner wall and of the outer wall. The first portions may be disposed parallel to the inner wall and separated from the first portions by a first distance along the structural sections. The protruded features may be interposed between two structural portions and an inner wall may be separated from second portions of the outer wall by a second distance that is greater than the first distance.

The method comprises: placing material to be processed within a material molding space of the molding machine, and supplying air to an air passage provided in the material by the air supplying module; heating the material by the heating module according to a preset heating parameter; and pressing the material by the pressing module according to a preset pressing parameter.

Method and apparatus for forming plastic preforms into plastic containers with intermediate blowing pressure control

A method for forming plastic preforms into containers, wherein a transport device transports the preforms along a transport path. The transport device has a rotatable transport carrier where forming stations are arranged for forming the preforms into containers. The forming stations each have devices which apply a flowable medium to the preforms, and the apparatus has three pressure reservoirs which store the flowable and gaseous medium to expand the preforms. The preforms are applied to a first operating mode with a first pressure level stored in the first pressure reservoir, and at least one second and one third pressure levels stored in the second and third pressure reservoirs. The second pressure level is higher than the first, and the third pressure level is higher than the second. The apparatus is operated in a second operating mode, which differs from the first mode by pressure level prevailing in the second pressure reservoir.
