Abstract:
A resin molding system 1 comprises a gripping device 3 provided with a gripping frame 30 for gripping a resin sheet material 2, a heating device for heating the resin sheet material 2 and a molding device for clamping a lower die 61 and an upper die, and affixing the resin sheet material 2 to a substrate 63. The molding device is provided with: a lowering device for lowering the gripping device 3 and causing the resin sheet material 2 gripped by the gripping frame 30 to approach the lower die 61; and a pair of bent posts 67, 68 which are provided on both Y-direction sides of the lower die 61, and which come in contact with portions of the gripping frame 30 when the gripping device 3 is lowered, and which convexly bend the gripping frame 30 upward as viewed from the side along the Y-direction.
Abstract:
A mold includes a forming insert that includes an upper portion and a lower portion. The upper portion includes a sidewall segment and a heel segment extending from a bottom of the sidewall segment. The sidewall segment has a sidewall radius, and the heel segment has a heel radius that is less than the sidewall radius. The lower portion extends axially downward from the upper portion to define a base cavity. A forming base is positionable within the base cavity. The rim has a rim radius that is less than the heel radius and the step has a step radius that is less than the rim radius.
Abstract:
Format change method for a thermoforming machine and a thermoforming machine. A station of the machine includes an upper tool and a lower tool, at least one of the upper and lower tools being suitable for moving in a substantially vertical actuating direction during the operation of the machine. In the method, the upper tool is supported on the lower tool and both tools are subsequently withdrawn from the station and are replaced with new tools. When withdrawing the upper and lower tools from the station and when introducing the new tools therein, the tools are moved simultaneously and jointly in a replacement direction different from the actuating direction.
Abstract:
A multi-well plate with wells having ultra-thin walls and yet with sufficient structural rigidity to allow reliable use of the plate in automated instrumentation is formed by first forming a plate blank by injection molding, the blank being of a thickness that provides the desired rigidity, and then subjecting the blank to vacuum forming to stretch designated areas in the blank to form wells or to extend wells already formed, the stretching resulting in a reduction in thickness of the molded resin at the walls of the wells only.
Abstract:
A combination packaging container includes a beaker-shaped inner container with a container jacket, a base and a flange projecting out from the container jacket in the region of its open end, as well as a sleeve-shaped outer part surrounding the inner container at its container jacket with end regions spaced apart from one another in the direction of a longitudinal axis. The inner container is laid against and molded onto an internal face of the sleeve-shaped outer part. The sleeve-shaped outer part is of a single-layered design between its end regions spaced apart from one another in the direction of the longitudinal axis. An end face of the outer part lying opposite the flange constitutes a standing surface for the combination packaging container.
Abstract:
PURPOSE: The present invention provides a molded article which comprises a substrate whose surface is covered with a film, has good appearance, and does not deteriorate in the appearance even in severe environment where the article is actually used, such as high-temperature environment.CONSTITUTION: A molded article comprising a substrate whose surface is partially or wholly covered with a film, wherein the film has an adhesive layer, the adhesive layer is in contact with the substrate and the surface of the substrate, which surface is in contact with the adhesive layer, has a surface roughness (A) of 3 to 20 μm.
Abstract:
The present invention relates to a thermoforming device for thermoforming a product (1) from a plastic foil (23), and to a corresponding method. The invention relates particularly to a thermoforming process and device in which a slot (2) is arranged in a product (1) to be formed. The invention also relates to a product (1), particularly a flowerpot, manufactured using this thermoforming device or method. The thermoforming device is characterized in that the cutting sleeve (10) and cutting plate (7) and/or hold-down element (8) define an auxiliary cutting line through which the plastic foil (23) is cut in order to arrange a slot (2) in the product (1) to be formed. The functions of slot-forming and product-foil separation are hereby performed by substantially the same components.
Abstract:
The invention relates to a process for producing thermoformed articles such as food packagings or parts thereof with a mechanical weakening between adjoining functional areas, which, for utilization by a user, can be at least partly separated at the mechanical weakening, in a thermoforming die having an upper die and a lower die, the mechanical weakening being introduced with a three-dimensional extension during the period of time during which the material to be formed is located in the thermoforming die, and a thermoforming die for implementing the process.
Abstract:
The present invention provides for various embodiments of a unitary fascia energy absorber including an aesthetic appearance while also providing improved energy management. In one embodiment the fascia energy absorber includes an outer member and an inner member joined together. The inner member has a base including a plurality of crush lobes and at least one of the plurality of crush lobes includes a projected wall spaced a distance from the base and at least one sidewall which extends from the base to the projected wall of the crush lobe. The plurality of crush lobes are spaced apart from one another and separated by a portion of the base. In another embodiment a process for producing a fascia energy absorber includes heating and forming a polymer sheets to form an outer member and heating and forming a second polymer sheet to form an inner member. The inner member and the outer member are then joined to form a fascia energy absorber.
Abstract:
An end face of an intermediate layer of a multilayer structure is stably covered by surface resin layers at a time of cutting the multilayer structure. A cutting method of the multilayer structure includes the steps of: compressing and deforming the multilayer structure, while extending respective layers of the multilayer structure to provide a thin thickness portion, so that an upper layer bites into a lower layer by pushing a push cutter, by a predetermined amount, into the multilayer structure supported by a cutter receiving portion, in a fused state of at least one of the resin layers forming the multilayer structure; and push-cutting the compressed thin thickness portion S till the push cutter abuts against the cutter receiving portion so as to converge an intermediate layer and surface resin layers of the multilayer structure to the abutting portion A of the push cutter and the cutter receiving portion.
