摘要:
The leaching chamber endplate including snap connectors, pipe stops, pipe scores, drill guide(s), and a barrier that facilitates enhanced engagement between the endplate and leaching chamber. This endplate is preferably formed using a blow molding process that forms, in situ, the endplate, including the snap connectors and the barrier.

A pallet includes an upper deck, a support material disposed within the upper deck, an upper frame member supporting the upper deck, a plurality of foot members disposed on the upper frame member, and a lower frame member disposed on the plurality of foot members. The upper deck includes a first half and a second half disposed in communication with a major face of the first half. Numerous variations in which the pallet is collapsible or includes reinforcement members are within the scope of the pallet disclosed.
摘要:
An arch shape cross section thermoplastic leaching chamber, having sidewall slot perforations which flare inwardly, is made using a mold comprised of a mold cavity part and an inwardly retractable mold core part. The core part has opposing side slides with projections that define the perforations; they are separated by a center block. The center block moves downwardly and the slides move inwardly, under action of slide rods built into the mold core, to enable a molded chamber to be removed from the mold.

In one embodiment, pallet substructure can comprise: a reinforcement structure disposed in a plane, a foot member, and a gusset. The gusset can be disposed in mechanical communication with the reinforcement structure and the foot member, wherein the gusset is configured to restrict movement in vertical directions when the substructure is oriented for use.

A method for manufacturing a mold component having a conformal thermal management system comprises forming a first mold segment and a second mold segment, each comprising a surface having a profile defined by the surface. A channel pattern is disposed beneath the profile defined by the surface in at least one of the first mold segment and second mold segment. The first mold segment and second mold segment are aligned to form a network of channels. The first mold segment and second mold segment are joined together to form the mold component.

In one embodiment, composite pallet comprises: an upper deck, an upper frame member supporting the upper deck, a plurality of foot members disposed in physical contact with the upper frame member, and a lower frame member disposed in physical contact with the plurality of foot members. The upper deck comprises a first half, a second half disposed in communication with a major face of the first half, and a support material disposed between the first half and the second half.
摘要:
A method for manufacturing a molded article comprises injecting a quantity of molding material sufficient for the preparation of the molded article into a cavity of a mold, injecting a first portion of fluid into the mold cavity, creating a gas channel within the molding material, and forming the molded article within the mold cavity. At least a portion of the first portion of fluid is exhausted through a gas port, a second portion of fluid is injected into the mold material, and the molded article is cooled within the mold cavity to a temperature beneath a softening point of the molding material.
摘要:
A leaching chamber has sidewall perforations which flare inwardly, so that the smallest perforation dimension is on the exterior surface of the sidewall. The basic axes of the perforations run downwardly toward the chamber base, as the axes run from the inside to outside of the chamber. Mold cores having inwardly retracting slides, and which move in complex ways, are used to form the chamber. Thus, perforations are present down near the base flange of the sidewall, even though the base flange has an upwardly extending fin.
摘要:
A thermoplastic chamber for leaching wastewater or other use, which is designed so that when jointed to a like chamber the horizontal plane angle between the chambers can be adjusted, has one or more stops which can be selectively used to prevent rotation, for instance, to make the joined-together chambers lie along a straight line. Preferably, the stop is integral part of the chamber base flange; and it hinges and bends upwardly when moved to its working position, so the stop engages and limits movement of the end of the mating chamber.
