EXTRUSION BLOW-MOULDING PLANTS

extrusion blow-moulding plants with accumulator head that are capable of making moulding parts from 20 litres up to 1000 litres of volume, mono layer and up to 6 layers. These plants have been particularly designed to meet the stringent requirements of the engineering plastics for technical and industrial articles. Fuel tanks, pipes and ducts, industrial containers, jerry cans, drums, technical mouldings and toys are few examples.

TA SERIES BLOW MOULDING MACHINE

The TA series includes a wide range of blow moulding machines with ACCUMULATOR HEAD specifically intended for extrusion moulding process. These machines have been specially developed for the production of a wide range of plastic mouldings products ranging from toys to air ducts and tanks for the automotive industry, jerry cans and plastic drums for the packaging industry. The extrusion ACCUMULATOR HEAD is of the First In First Out type with 4 cardioids to get a balanced superposition of material flows, to prevent stagnation points and allow quicker colour and production change operations. The extruders mounted on the TA series blow moulding machines are high performance single-screw type, with intensely cooled and grooved bushes. The efficient thermal division of each heating zone allows optimal control of process temperatures. Core and die replacement is easy to perform and a device to control the actual position of the core and die (patent pending) is also available. All TA series blow moulding machines feature a special clamping unit design with a "tie-bar less" structure (without columns) that allows the mounting of oversized mouldsand makes the extraction of the manufactured piece easier. The blowing unit is mounted in an easily accessible position, with a wide range of adjustment and devices. The system of monitoring and control of the TA series blow moulding machines is based on the latest generation software program, customized according to the specific needs of the end user. Self-diagnostic systems with connections for remote assistance, the storage of all production data and the interface with the corporate network of the customer complete the equipment control system.

ASPI SERIES BLOW MOULDING MACHINES

The blow molding machines of the ASPI series use suction blow molding technology, which allows a customized plastic processing, according to the needs of the customer. The technology of 3D blow molding was created to meet the needs in the automotive industry for the production of tubes and pipes of various kinds. In addition to the car market, it can be used in other application areas, one of the most promising is that of household appliances (white goods), where there is a demand for long pipes with sometimes very complex shapes, which lead to real product innovation.
In the ASPI suction process, the parison is extruded into the cavity after having closed the two half-moulds. A flow of "vacuum" is produced at the opposite end of the tool to the introduction of the parison, causing the parison to "walk" along the entire length of the cavity to the desired position. Only then it is possible to close both ends of the parison, perforate it with one or more needles and blow air inside.

The suction blow molding technology offers various advantages, including:

- Scrap reduced to just the top and the bottom where the parison is closed.
- Ability to work with materials with high process temperature.
- Ability to produce parts with very complex three-dimensional and pronounced shapes.
- Reduced cost for deflashing equipment.
- Considerable energy savings.

The ASPI blow molding machine is presented in two different configurations:

- MONO when it is necessary to produce blow molding products with one material;

- CO-EX when it is necessary to produce plastic moulded parts with different overlapping materials in layers (longitudinal co-extrusion), or items with different materials in a sequential arrangement (sequential co-extrusion)

ISIT SERIES BLOW MOULDING MACHINES

The ISIT series are accumulator head blow moulding machines which use a “3 platen” clamping system, where the force is applied to the rear of each platen by a cross beam. This avoids an unbalanced transmission of clamping force to the mold platen and, at the same time, allows the utilisation of over-sized moulds with dimensions greater than the platens themselves. The clamping movement is equipped with a rack synchronization system, prismatic guides with roller bearings and two diagonal tie-bars.

The “3 platen” design offers and excellent technical/economic solution that offers the possibility to produce plastic articles of large dimensions and to mount the moulds from the above. The full range of Isit series includes models 400 - 500 - 800 - 1300 - 1600. The "2 cardioid" accumulator heads, First In First Out type, provide a layering and a balanced structure to the parison.

The extrusion of the material and parison thickness are controlled on "500 points", ensuring the highest quality of the manufactured piece. The single-screw extruders, are based on "HEX" technology (High extrusion), high capacity and plasticizing quality. Therefore, higher outputs of plasticized material are obtained using smaller screw diameters, reducing the power consumption and saving a considerable amount of energy.

EC-COEX BLOW MOULDING MACHINE SERIES

The co extrusion blow molding machine (EC-COEX) series includes continuous extrusion blow moulding machines based on multilayer technology with "3 platen" clamping units, with stretched diagonal tie bars, single or double carriage.
The "3 platen" clamping unit allows a wide opening of the mould platens to facilitate the production of large dimensioned industrial articles allowing the moulds to be mounted from the above.
The extruders installed on the EC-COEX series, are of the "HEX" (High Extrusion) type, high-capacity and plasticization quality. These are mated to continuous extrusion heads, up to 7 layers, and a 500 point parison thickness control.
The blow moulding machines of the EC-COEX series are dedicated to the production of packaging articles, plastic drums, plastic tanks, IBC containers and fuel tanks.
