BLOW MOLD FOR PLASTIC BOTTLE
20240269913 · 2024-08-15 · ·

Disclosed is a blow mold for plastic bottle, which comprises: a mold body, two exhaust channels, a label plate, and a vacuum suction assembly; the mold cavity is arranged in the mold body, the mold cavity is used for shaping the bottle embryo; the two exhaust channels are connected to the mold cavity; the vacuum suction assembly is connected to the two exhaust channels and used to suction out the gas inside the mold cavity. The present disclosure starts the vacuum suction assembly when blow molding the bottle embryo to carry out an active exhaust operation, reduces the generation of air bubbles between the bottle embryo and the label plate and the interior of the label plate, improves the adhesion between the bottle and the label plate, also reduces the air bubbles and delamination of the interior of the laminated label plate in the process of blow molding

Blow mold array, stretch blow molding machine and method

A blowing mold array includes a blowing mold unit forming a cavity, inside of which plastic preforms are expanded to plastic containers. The blow mold unit includes a blowing mold retainer having at least two mold retainer elements for accommodating parts of the blowing mold unit, and a locking mechanism to arrest at least one part of the blowing mold unit against at least one mold retainer element. The locking mechanism includes an engagement element that can be pivoted and/or shifted relative to a default axis, which in an arrested state abuts a segment of a part of the blowing mold unit. The locking mechanism has an actuating element to loosen the arrest between the mold retaining element and the blowing mold unit. Actuation of the actuating element is coupled with actuation of the engagement element.

POLYMERIC MATERIAL FOR CONTAINER

A formulation for producing a polymeric material including high-density polyethylene, a chemical blowing agent, and other optional components is described.

Container and process for making the same

A vessel is configured to hold a product in an interior region formed in the vessel. The vessel includes an inner layer arranged to define the interior region and an outer layer. The vessel is formed using a blow-molding process in which a multiple layer parison is blow molded to form the vessel. The multiple layer parison is formed in an extrusion process in which a number of extruders are arranged to co-extrude associated.

A tooling system for fabricating a composite structure comprising a printed thermoplastic material tooling component having a non-tooling surface and a tooling surface, wherein the tooling surface defines a predetermined shape for the composite structure. The tooling system may further comprise a printed thermoplastic material tooling base structure having a plurality of non-tooling surfaces to support the printed thermoplastic material tooling component during layup or cure. The printed thermoplastic material tooling base structure may employ a support structure, such as a honeycomb support structure or a filler material.

MULTI-LAYER TUBE AND PROCESS OF MAKING THE SAME

A vessel is configured to hold a product in an interior region formed in the vessel. The vessel includes an inner layer arranged to define the interior region and an outer layer. The vessel is formed using a blow-molding process in which a multiple layer parison is blow molded to form the vessel. The multiple layer parison is formed in an extrusion process in which a number of extruders are arranged to co-extrude associated inner and outer parisons to establish the multiple layer parison.

Apparatus and method for transforming plastic parisons into plastic containers with air discharge

A blow mould for producing plastic containers comprises at least two blow mould parts and a hollow space formed from the at least two blow mould parts at which plastic parisons are transformed by an application of a flowable medium to the plastic containers. The hollow space includes an interior wall that has a contour which produces a predetermined configuration of the plastic containers. A first portion of at least two blow mould parts produces a bottom of the plastic containers. A second portion of the at least two blow mould parts has an opening region for discharging a gaseous medium during an expansion process of the plastic containers. The opening region extends along a first line and a second line, wherein the first and second lines run at least in some sections of the blow mould at an angle different from 0 relative to one another.
