Process and machinery for integration of discrete parts into composite containers
A process of manual, semi-automatic and fully-automated integration of discrete components into a container that results in fast, reliable, cost-effective, and scalable production of composite containers is disclosed. The process can be embodied in manufacturing equipment that has a series of stations and may be called an assembly device. The equipment can produce containers, tubs, canisters, cartridges, etc. which are easily separated into different bio-degradable or compostable parts. Other container types are possible and are contemplated.
Method for producing plastics containers
The invention relates to a method for producing plastics containers (15) from thermoplastics with inserts (13) which, by exploiting the heat of plasticization, are connected during shaping of the plastics container (15) by a material bond and/or interlocking connection to the container wall (140), wherein the method provides the use of at least one opening (26) on the insert (13), which opening forms a melt duct or melt inlet and/or melt passage for plasticized or plastic material of the container wall (140), wherein the method is distinguished in that the opening (26) is monitored as a reference opening (26) by optical and/or sensory means during the production of the connection, wherein the degree of penetration of the opening (26) with thermoplastic from the container wall (140) is used as a measure of the quality of the connection.
METHOD FOR MANUFACTURING A PLASTIC FUEL TANK WITH IMPROVED CREEP STRENGTH
A method for manufacturing a plastic fuel tank including: a) inserting a plastic parison including two distinct parts into an open two-cavity mold; b) inserting a core, bearing at least part of a reinforcing element configured to create a link between the two parison parts, inside the parison; c) pressing the parison firmly against the mold cavities, for example by blowing through the core and/or creating suction behind the cavities; d) fixing the part of the reinforcing element to at least one of the parison parts using the core; e) withdrawing the core; f) closing the mold, bringing its two cavities together to grip the two parison parts around their periphery to weld them together; g) injecting a pressurized fluid into the mold and/or creating a vacuum behind the mold cavities to press the parison firmly against the mold cavities; and h) opening the mold and extracting the tank.
Flexible container made of a plastic material, method for manufacturing such a container and corresponding mould
A container obtained by blow-moulding a rolled tube. The container includes a body extending, according to a longitudinal axis, between a bottom and a neck made integrally in one-piece with the body. The body has, along a height according to the longitudinal axis, a wall having a thickness between 0.05 mm and 0.4 mm. The neck has, along the height according to the longitudinal axis, a wall having a thickness between 0.4 mm and 0.8 mm.
