Coldbox Process 101

Learning Outcomes

  • Explain the benefits of using the coldbox process for coremaking.
  • Explain the coldbox coremaking process.
  • Explain the components of the three most common coldbox systems.
  • Identify how sand, binder and equipment selection can impact the quality of cores.
  • Describe the important safety measures and operating practices to use while making coldbox cores.
  • Identify the key aspects of well-designed tooling.
  • Identify common coldbox-related casting defects.

Course Introduction

This course is an introduction to the coldbox coremaking process used within a metalcasting facility. Discussion will include terminology, common sands and binder systems used to make coldbox cores, the coremaking process, using and maintaining equipment, and considerations for identifying core defects. 

Benefits to Taking the Course

Participants walk away with a broader knowledge of the coldbox process, gain ideas on how to more effectively utilize their current process, and explore different, perhaps unfamiliar, options for improving their process. Attendees also leave the course knowing the 12 key factors to consider when selecting a binder system.
