3th Europe Rubber Processing Education Week 2016

3rd Europe Rubber Processing Education Week, 2016

Abstract :

The 3rd Europe Rubber Processing Education Week, 2016 will be held in H 10, Marina Hotel, Barcelona/Spain, during 7-10 Nov. 2016. This event is dedicated to engineers and  directors in the rubber processing industry who are keen are getting to know with the latest developments in this sector. This 4-day event will cover the topics outlined in more detail below:


Rubber Compounding: Principles & Formulation Development (7-8 November 2016)

(Instructor: Dr. Hans-Joachim Graf)

This course is designed to review and submit a detailed knowledge of rubber compound formulation design. The ingredients used in the formula have a relation to properties and processing performance. The participant will learn and practice how to find and use those relations through research. Methods and tools are illustrated and demonstrated, which enable the compounder to build his own knowledge about the functions of ingredients in the compound. This knowledge enables the compounder to fulfil his responsibility on material and processing cost in rubber manufacturing, which requires engineering techniques and tools. At the end of the seminar the participant should be in a position to adopt these tools and use them in his daily and strategic work. Participants will receive “Graf Compounder Software”, a tool, which will be useful to accelerate the formulation development.

Program Outline :

  • Introduction to formula design.
  • Ingredient – Property relations.
  • Functions of materials in a rubber compound.
  • Polymer, filler and process oil as the basic building block.
  • Cross-linking and accelerator system in relation to part and processing performance.
  • Specification regarding formula design.
  • Formula development methods and tools.
  • Consideration of compound cost and formula design

Rubber Mold Design: Principles, Best Practices & Common Mistakes (7-8 November 2016)

(Instructor: Van Walworth)

During this 2-Day Course, participants will be exposed to numerous principles of mold design features for a variety of rubber molding processes, focusing primarily on compression, transfer, and injection. An assortment of mold design practices and examples will be presented; comparing recommended best practices to lessor recommended practices, as well as mold design mistakes which should be avoided all together. The instructor will draw upon a 35 year career of experience, personal practice, and observation to present many mold design techniques; from which novice practitioners will gain an immense amount of helpful information while seasoned practitioners will be presented with valuable insights and novel applications.

Program Outline:

  • Mold Design Information – Getting Started
  • Mold Building Material Selection Guide
  • Mold Surface Finish Options
  • Mold Surface Treatment Options
  • Registration Techniques
  • Cavity Insert Techniques
  • Parting Line Innovations
  • Tear-Trims & Over-Flows
  •  Gates & Vents
  • Mold Plate Management
  • Transfer Pot Design & Sealing
  •  Runner Layouts & Cross Sections
  • Mold Design Options For Productivity Improvement

Rubber Mixing Plant: Design & Layout (9 November 2016)

(Instructor: Bruno Milanese)

Mixing Plant Line for rubber parts can be designed in different ways compared to tires. This seminar is focusing on selection and criteria of equipment required and layout of a rubber mixing line to operate a plant efficiently. Whereas a compounding line for production of tires is quite the same for most of tire producers, a compounding line for technical rubber goods can be designed in many different ways because of the wide range of recipes to be produced. Flexibility and easy access to the equipment is a must, as well as efficient cooling of the compound. Surprisingly, shape of rotors is of much less importance than normally considered. This course is suitable for both technical and non-technical people at rubber compounders.

Program Outline

  •   Targets of compounding
  •   line for tires vs. compounding line for technical rubber goods (TRG)
  •   General lay out and features of main equipments 
  •   Internal Mixer: forces acting inside the mixing chamber, deformation of rotors
  •   Design of dust stop seals
  •   Considerations about friction ratio between tangential rotors and their impact on rotor deformation
  •   Impact of rotor deformation on dust stop seals
  •   Internal Mixer: tangential vs intermeshing rotors: some consideration about heat transfer
  •   Comparison between continuous and discontinuous process and consequences about rotor shape
  •   Downstream the Internal Mixer: roll mill vs. twin screw Extruder

Rubber Injection Molding (10 November 2016) 

(Instructor: Dr. Hans-Joachim Graf)

Injection Molding of Rubber is a multi parameter process. Machine, Mold and Material interact and effect each other. This course will provide an understanding that the participant gets the ability to manage such a process. After an introduction of the injection molding machine, followed by a detailed description of the plastification units and their function and influence on the operation, a process model is provided. This model leads to experiments, which allow to construct an operating window, which is a tool to govern the process. Principles of mold layout and compound design with special regards to rheology is discussed. The participant will learn how this triangle can be understood and handled to achieve a stable manufacturing process. As a precondition, the molding machine must provide all necessary functions, therefore guidance, how to access the molding machine is discussed. We all see still defects on molded rubber parts, which make troubleshooting necessary. The course is completed with a discussion of some specific newer molding techniques and developments

Program Outline

  • Introduction to Molding of Rubber
  • Rubber Injection Molding Machine
  • Injection Molding Process
  • Injection Mold Design
  • Compounds for Injection Molding
  •  Assessment of an Injection Molding Machine
  •  Troubleshooting in Rubber Injection Molding
  •  New Developments in Rubber Injection Molding

Adhesion of Rubber (11 November 2016)

(Instructor: Dr. Hans-Joachim Graf)

Reinforcing elements are widely used in rubber parts for the automotive and construction industry. There are a few principles, which are supported scientifically and technologically. After an introduction into the principles of adhesion, manufacturing of rubber metal parts are discussed from metal preparation to moulding process is discussed. A troubleshooting guideline is provided based on these principles. Rubber to rubber, rubber to TP/TPE, or rubber to fabric/fibres requires differing process mechanisms – even so, these mechanisms share certain aspects and similarities which are discussed in this seminar. The participant will be exposed in this seminar to knowledge which governs almost all aspects of bonding. With the in depth understanding of the principles and how they apply to daily operation in rubber reinforcement participants should have an enhanced ability to develop a solution for most rubber bonding problems.

Program Outline : 

  • The physics and chemistry of adhesion
  • Rubber to metal adhesion an manufacturing
  • Process considerations moulding rubber to metal parts
  • Adhesion testing and troubleshooting
  • Technology of rubber to rubber adhesion
  • Rubber to Plastics (TP/TPE) adhesion
  • Manufacturing aspects of two component parts
  • Chemistry of Rubber to fabric / fibres bonding
