Bottles, Preforms and Closures, Second Edition: A Design by Ottmar Brandau

By Ottmar Brandau

As a specialist to the plastics undefined, Ottmar Brandau’s concentration is on utilizing his engineering knowhow and creation administration event to enhance caliber and productiveness, curb cycle time and introduce secondary strategies resembling inline printing. This publication is a completely functional guide that gives engineers and executives with the toolkit to enhance construction and engineering facets of their personal companies – saving cash, expanding output and bettering competitiveness through adopting new technologies.

In this publication, Brandau covers the engineering elements of bottle construction and the proper creation techniques (focusing on blow molding), in addition to plant format and association and creation administration, to supply the definitive instruction manual for engineers and executives alike.

  • Learn the methods of the alternate from an skilled engineer and manager
  • Save funds: sensible recommendations to enhance cycle times
  • Increase productiveness: increase plant structure and association and enforce secondary approaches akin to inline printing

Other variants of heat-resistant bottles are used for applications where the bottles are sterilized with heated steam before filling or bottles are conveyed through a pasteurizing system after filling. The related temperature load (temperature and duration) may result in other requirements for the selection of the mold concept. 5 2 >2 30 14 26 12 Max. 1 Mold Design After the bottle geometry and the mold concept have been determined, as described in the previous sections, the focus shifts to the mold.

2 Purpose-made Preform Depending on the bottle design and its performance requirements, it may be necessary to create a special preform with the ideal geometry for the bottle to be produced. 17 2D Drawings of preform designs are typical in the industry.

Think process – not product! 16 High-end CAD system allows the visualization of textures. 4 From Shape to Full-Fledged Design for a Dependable Process Once the initial outer appearance of the bottle has been visualized and agreed upon, the shape must be implemented in a bottle design that ensures a high level of process dependability and will also include the wall thickness and its distribution. The first step in this stage is the design of the preform. 1 From the Ideal to the Real Preform Based on the dimensions of the bottle (height, diameter, capacity, and desired weight) and the selected or required neck design, the ideal preform geometry for the bottle is determined.
