Coldbox Process 201

Learning Outcomes

  • Summarize the coldbox coremaking process.
  • Compare differences in properties of coldbox binder systems.
  • Evaluate raw material and equipment options for coldbox coremaking.
  • Identify the best corebox tooling variation for the catalyst type in use.
  • Explain common corebox tooling challenges and how to adjust a process to improve the outcome.

Course Introduction

This course is the second course in the coldbox coremaking series and provides the next level of knowledge in relation to the molding process using within a foundry to make coldbox cores. Discussion will cover coldbox terminology, common sands, additives and coatings used, coldbox binders, in particular PUCB, corebox equipment, corebox tooling and best usage parameters, and considerations when troubleshooting and optimizing the process for proper quality assurance.
