Material Drying Technology

Our two Material Drying Technology courses will provide participants with a better understanding of how different polymers are best dried and prepared for reliable processing. These courses show participants how proper material handling and drying is critical to produce a consistent product and process. Course One reviews polymer basics, as well as both hygroscopic and non-hygroscopic polymers – to better convey the importance of properly drying water-sensitive materials.

These programs identify drying as a critical step when processing any plastic and teach participants that proper preparation, handling, monitoring and controlling moisture levels results in higher quality parts, higher production yields and more consistent processing. Material Drying Technology, Course Two focuses on the operation and utilization of Hot Air Dryers, Compressed Air Dryers, Desiccant Dryers, and Vacuum Dyers in today’s production environments. Course Two also teaches the participants how to Calculate Material Consumption, Residence Time, and Dryer Capacity.

Establishing a Scientific Molding Process

This course provides participants with in-depth processing information to better prepare them for making appropriate and cost-effective decisions when establishing or improving a scientific injection molding process.

This scientific course teaches a process strategy that properly decouples 1st stage fill from 2nd stage pack. Students who understand and utilize the strategy described in this course will produce processes with a much higher repeatability. The steps outlined in this course are intended to reduce downtime and improve process efficiency.

• General Rules for Scientific Processing
• Process Optimization Strategies:
  ·    1st Stage Filling
  ·    1st Stage to 2nd Stage Transfer
  ·    2nd Stage Pack
