The global impact of COVID-19 on our people and the global economy is significant, and Watlow has taken a comprehensive approach to deal with the current crisis. Our contingency planning includes protecting our team members, communicating often with our customers and partners and maintaining the continuity of supply lines.

At the beginning of the pandemic, we set two priorities that guide our responses and decisions: the health and safety of our team members while continuing to supply essential products needed by our customers.

If you have questions about how the pandemic is impacting Watlow or Watlow’s response, please contact your Watlow representative.

Multi-zone MULTICELL Heaters Produce Required Thermal Gradients In Platen Application

Problem:

A manufacturer was having trouble achieving the necessary temperature tolerances to properly cure metal matrix composite parts. The platen used in the process was unable to develop the temperature gradients called for by the curing process.

Solution:

Watlow solved this problem by supplying MULTICELL heaters containing three independently controllable heat zones. These zones permitted segmenting the platen into the correct size and heat segments' for the parts. Tight temperature control was further enhanced by assigning each heater's zone to its own PID temperature control. Heating objectives were exceeded and the whole process upgraded.
