"Very informative - good class!"
Overview
This course is the second course in the coldbox coremaking series and provides the next level of knowledge in relation to the molding process within a foundry to make coldbox cores. Discussion will cover coldbox terminology; common sands; additives and coatings used; coldbox binders, in particular, phenolic urethan cold box (PUCB) resin; corebox equipment; corebox tooling and best usage parameters; and considerations when troubleshooting and optimizing the process for proper quality assurance.
Learning outcomes
Class participants will be able to:
- 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 outcomes.
- Describe ways to optimize the core production processes.
- Describe the important safety measures and operating practices to use with coldbox binders and equipment.
