Detailed description

Do you want to blow mold a wide variety of batch sizes of different bottle packaging flexibly, quickly, and cost-effectively? With the new HESTA blow molding machines of the HG & HGD series, you are well equipped for any job and have the greatest possible flexibility up to 8 or 2×8 bottles per cycle.

For example, you can run a high-volume order with the highest possible number of nests. Precisely, economically and, depending on requirements, also just-in-time - with minimized warehousing. Shortly afterwards, you can produce articles of larger dimensions with a reduced number of nests. And in between - thanks to fast, simple die changes - there are only short setup times. In this way, you achieve low unit costs with flexible production and optimized capacity utilization.

The advantages for you:

  • High flexibility due to fast mold change: from 1-cavity to 8-cavity molds
  • High output for both large and small batch sizes
  • High article quality due to new HESTA hose heads
  • Energy-saving, high-performance extruder with unique extruder drive worldwide
  • Short changeover times due to directly flanged masks
  • Long service life with precise mold guidance due to open clamping system with direct
  • Closing force application without bending stress on the guide rails
  • Safe one-sided discharge of the tested bottles by means of two-station masks on the mold in the single-station version, left & right in the double-station machine, or also one-sided directional with height-adjustable conveyor belt.
  • Variable transfer options to the subsequent stations
  • Low adjustment effort, as no transport rails are required
  • Can be universally equipped with aftercooling station, circle cutter and bottle tester
  • Convenient machine operation
  • Low space requirement due to very compact, open design with good accessibility
  • Favorable price-performance ratio with high quality new HESTA quality standard.

For heating everything: Our universal extruder

The universal extruder is arranged horizontally. Patented interchangeable feed bushes that can be removed from the side facilitate and shorten the set-up times. The extremely time-consuming disassembly of the extruder drive and the subsequent pressing out of the feed bush is completely eliminated with new HESTA! This makes it the only true four-sided extruder in the world and allows the use of all blowable materials, in powder or pellet form, with or without the addition of regrind. By means of a speed control, the cycle time of the machine can be kept constant. Depending on the material, appropriate screws, with or without mixing section, are used. The unique extruder drive is not only energy-saving but is driven by four individual motors. This makes it easy to replace a single motor, and also allows emergency operation or operation with reduced power while simultaneously repairing a single motor.

Our wall thickness control:

The electronic wall thickness control with maintenance-free crank drive is mounted directly on the extruder, which means that it remains on the machine even when the head is changed, allowing the shortest possible set-up times and low acquisition costs for an additional parison head. The wall thickness is pre-programmed with 100 points over the entire tube length, this can be done manually or also drawn in, the time sequence automatically adapts to the cycle time of the blow molding machine.

Our hose head:

An Schlauchköpfen steht eine fein abgestufte Auswahl zur Verfügung, in Einfach-oder Mehrfachausführung, Mono- oder Mehrschichtausführung, Stegdorn-, Pinolen- oder Wendelausführung, für alle gängigen Düsenabstände. Unser einzigartigen Vario-Köpfe können durch Austausch einer Einspeißplatte vom ursprünglichen Monokopf auf Sichtstreifen oder DeCo2 Kopf nachgerüstet werden. Diese Flexible und Günstige Nachrüstung ist Weltweit einzigartig.

Hose knife:

Cold and hot cutting systems are available for cutting the hose, these are pneumatically driven, but can also be extended by our unique electric high-speed knife. With a speed of up to 12 m/s, this knife cuts the hose before it is affected. This reduces the folding of the hose to a minimum. The portfolio is rounded off by our hose closing and cutting device with controlled supporting air. Immediately after the hose cutting process, the extruder is lifted in the head area by means of a maintenance-free crank drive, whereby the feed hopper or any conveying equipment placed on top remain unaffected by the unique ball cup and do not move.

Airy in shape: Blowheads

Mit dem Universalblaskopf ist wirtschaftliches und zeitsparendes Mehrfachblasen möglich – von 1fach bis 8fach. Die Anzahl der einzelnen vormontierbaren Blasdorne richtet sich nach der Anzahl der Formnester. Das Kalibieren erfolgt elektrisch mit einem Wartungsfreien Kurbeltrieb mit 30kN Kalibriekraft. Der Universalblaskopf wird doppelseitig sicher geführt; das patentierte Kalibrierkissen sorgt für einfache 0-Punkt Kalibrierung der Blasdornhöhe zur Abschlagkante in der Form, und reproduzierbare eingestellte Kalibrierkraft bei jedem Zyklus. Der Universalblaskopf lässt 1-fach-, bis 8-fach- Blasen zu. Er kann auf alle verfügbaren Düsenabstände über Positionspassnuten eingerichtet werden. Große Querschnitte sorgen für ausreichen de Luftmengen. Die Blasdorne sind bis zur Spitze wassergekühlt. Es ist auch möglich, eine Schrägkalibrierung vorzusehen.

Courted transportation:

The blown articles are removed from the blow mandrel by masks attached directly to the blow mold and transferred to the downstream station in one plane, eliminating the need for alignment and setup and saving extreme setup times. With double masks, a further downstream station (e.g. for leak testing) can be served. During transport, the hollow bodies are well cooled and the output rates are increased. Neck and base slugs, as well as handle waste, are removed by pneumatic punching cylinders.

new HESTA's unique tool change concept:

As a new feature, the machine has a patented blow molding and deflashing system. The main mold parts, such as the base mold/mask and punches, can be exchanged with minimum effort and without readjustment during the next makeready process. The transfer masks, which are designed for several subsequent stations, are attached directly to the associated blow mold halves. The mold parts required for post-treatment fit with maximum precision into the standardized receptacles on the machine side. This makes it possible to exchange both the blow molding mask unit and the mold parts in the downstream stations from machine to machine with minimum effort and without readjustment during a new setup process. The blow molds are pre-assembled in their mounts so that they can be easily and quickly installed during mold changes. Thanks to this modern die change technology, changeover times are significantly reduced, setup work and the one-time setting of die cutting tools are simplified, and thus the overall degree of utilization is increased. The machine is equipped with the proven2-circuit cooling system with direct cooling water supply via the clamping plates and O-ring sealing.

Open and closed, back and forth: The locking system

Das offene C-Rahmenschließsystem mit zwei unten liegenden Holmen hat einen stufenlos einstellbare Schließkraft bsi zu 120 kN und wird ebenfalls durch einen Wartungsfreien Kurbeltrieb angetrieben, sowie einstellbaren Formöffnungsweg. Die Holme unterliegen keiner Biegebeanspruchung und bewirken daher eine exakte Führung der Spannplatten, einzigartig ist die Rückführung des Kühlwassers durch die Holme selbst. Das patentierte Schließkissen ermöglicht Ihnen vollautomatisch die Formdicke von +- 5 mm zu kalibrieren, die Schließkraft kann ebenso im Set-Up Modus auf Ihren Artikel optimal eingestellt werden. Menschliche fehl Einstellungen sind bei new HESTA ausgeschlossen. Sollte während der Produktion die Maschine eine minimale Abweichung erkennen führt diese sofort einen automatischen Set-Up durch und stellt die Schließkraft ein. Das Blaswerkzeug ist frei zugänglich. Die Leichtbauweise ergibt geringe Massen und damit kurze Taktzeiten. Zwei getrennte Kühlkreisläufe stehen in jeder Schließplatte zur Verfügung, wobei der integrierte Kühlkreisanschluß durch die Schließplatten nicht nur zum Schnellwechsel einen großen Beitrag leistet. Auch Fehlanschlüsse sind ausgeschlossen. Zur Erleichterung des Werkzeugwechsels ist eine zusätzliche, seitliche Tür an die Schutzhaube angebracht. Hier, wie bei allen übrigen Bauteilen, sind neueste Sicherheitsempfehlungen berücksichtigt.

Drive to save: E-drives and pneumatics

Energiesparende Servoantriebe versorgen die Extrusionseinheit, die Verschiebe- und Schließbewegung sowie das Kalibrieren. Die dazugehörigen Servodrives von Beckhoff entsprechen immer der neusten Generation, und ermöglicht wirtschaftliches Produzieren durch optimale Anpassung der Energieaufnahme an die Auslastung der Maschine. Die Pneumatik steuert die Funktionen Blasen, Kühlen, Transportieren. Stanzen und Auswerfen mit bewahrten, ausgereiften Elementen. Die Standard Pneumatikventile sind servicefreundlich auf einer zentralen Grundplatte angeordnet.

Control cabinet & control system:

The electrical control cabinet is vibration damped, easily accessible and service-friendly mounted on the machine. The programmable logic controller with front panel meets the highest demands for reproducibility, simply, safely and clearly. It allows individual input of all set values for the motion sequence, heating and wall thickness control, and the integrated bottle tester. An internal background memory facilitates setpoint optimization. All entries and fault messages are displayed in plain text. The warning and monitoring systems included in the basic equipment control the entire machine sequence. In the basic version, four authorization levels protect against unauthorized inputs; personalized login can also be enabled as an option. Inputs and all fault messages are recorded for process tracing. For easy operation, two monitor sizes are available depending on the machine type. The color 12 and 21 inch touch panels are directly connected to the Windows based modular control system. Any number of setpoint records can be stored on an internal memory or conveniently on an external memory via a USB socket. This shortens changeover times, especially for small batch sizes, and increases cost-effectiveness. All common languages can be switched easily and quickly. Preparation for online service is a matter of course for us and easily possible by means of pre-installed software.

If you want more: Our accessories

  • The fully automatic production of wide-necked containers is carried out by circular cutters with optional electrically or pneumatically operated revolving knife for removing the lost head outside the mold in the trimming station, whereby horizontal or vertical cutting is possible.
  • Zur Dichtigkeitsprüfung und Halskontrolle wird das voll integrierte Flaschenprüfgerät eingesetzt. Diese kann wahlweise noch durch eine Halsdurchgangsprüfung erweitert werden. Schlechte Artikel werden somit erst gar nicht übergeben und fallen direkt auf des Butzenabfallband. Da 100% geprüfte Flaschen aus der Maschine transportiert werden gehören Reklamationen über undichte Flaschen beim Endkunden der Vergangenheit an.
