Clamping, pinch-off, venting, and cooling defined for your blow molding machine.
The mold must match the machine, head, material, parison, volume, geometry, trimming, and cycle. Fundimoldes integrates engineering, machining, assembly, and validation.
Want to make a plastic bottle or container?
A blow mold has two halves with the outer shape of the container. In extrusion blow molding, the mold closes on a hot plastic tube and air pressure expands it until it copies the cavity.
To produce bottles, containers, vessels and thin-walled technical hollow parts in series.
When the part is hollow, has a neck or opening and is produced in volume. For very large tanks and vessels, rotational molding is usually considered; PET beverage bottles start from an injected preform that is stretched and blown.
Fundimoldes designs and builds the mold. Containers are then produced on a blow molding machine, usually at the customer’s plant or their molder’s. Step by step: how to make a plastic bottle or container.
Types and scope.
Cavities for consumer or industrial containers. Ideal for: Packaging, chemicals, cleaning products, and food, subject to materials and regulations.
Hollow geometries with handles, functional areas, or assembly features. Ideal for: Industrial and automotive applications.
Extrusion blow molded components with a technical function. Ideal for: Ducts, tanks, and special parts.
Configurations with cooling circuits to stabilize temperature and cycle. Ideal for: Series production and dimensional control.
Technical data sheet.
Blow molding and extrusion blow molding of hollow parts
To be validated based on blow molding machine, volume, and part weight
Aluminum, steel, or combinations depending on cycle
Dimensional inspection, clamping and cooling tests
Actual capacity subject to technical validation based on geometry, weight, material, tolerances and process.
How we work.
We review CAD, volume, material, weight, neck, handles, finish, and tolerances.
We validate platens, stroke, clamping, head, extrusion, connections, and cooling.
We define cavities, parting line, pinch-off, venting, cooling, and mounting.
We machine and assemble components in aluminum, steel, or a combination.
We verify clamping, cooling, geometry, and demolding according to scope.
Technical considerations.
It must seal and cut the parison in a way compatible with the material, wall thickness, and process.
Air evacuation affects surface detail and cavity filling.
The circuit must balance cycle time, stability, and maintenance access.
Platen, clamping, head, extruder, connection, and envelope data are required.
