HTS Engineering Journal | Summer 2026
Practical engineering insights, industry updates, and resources to help you get more from your furnace operations.
In this quarter’s newsletter: Learn how proper furnace circulation improves efficiency, explore our new technical resources on zinc dross pumping and preheat stations, and see how HTS is advocating for the die casting industry in Washington.
Engineering Insights
Furnace Efficiency Begins with Circulation
When seeking to improve furnace efficiency, you need to look beyond burners and temperature settings. However, one of the biggest contributors to furnace performance is what’s happening beneath the surface.
Without proper circulation, molten metal can develop temperature stratification, where hotter and cooler zones exist within the bath. This leads to inconsistent alloy quality, longer melt times, increased dross formation, and a reduced lifespan for your refractory liner.
Our pump systems are precision-engineered to your exact furnace geometry, ensuring optimal flow and consistent thermal uniformity. Continuously moving molten metal through the bath improves heat transfer, produces more consistent alloys, and reduces energy consumption.
Have questions about your application? Our engineering team is available to discuss your furnace and recommended efficiency improvements.
Customer Resources
We’ve recently added two new technical brochures to help customers improve safety, maintenance, and operational efficiency.
NEW: Zinc Dross Pumping Guide
Zinc dross removal from galvanizing baths is an important process of furnace maintenance, but the process can be slow or disruptive. Our newest brochure explains how dedicated pumping systems help remove zinc dross efficiently while improving safety and reducing downtime.

NEW: Preheat Station Guide
Introducing cold equipment into molten aluminum creates unnecessary risk. Proper preheating helps remove hazardous moisture, reduce thermal shock, and extend equipment life.

Industry News
Representing the Die Casting Industry in Washington
At High Temperature Systems, we believe supporting our customers goes beyond the equipment we manufacture.
David Defer, our sales representative and policy liaison, joined representatives from the North American Die Casting Association (NADCA) in Washington, D.C., in June to meet with members of Congress and discuss issues affecting manufacturers across the US.
The conversations focused on ongoing USMCA trade discussions and how tariffs continue to impact the die casting supply chain. By participating in these talks, HTS helps ensure the perspectives of equipment manufacturers and foundries are represented as trade policy evolves.

Upcoming Events
HTS Company Picnic - We will be closed July 31st
We will be hosting our annual company picnic on July 31st. As a result, our office and production will be closed. We will resume normal business hours on Monday, August 3.
Join us at the NADCA Tabletop Show this September
High Temperature Systems will be attending the North American Die Casting Association (NADCA) Tabletop Show as delegates this September to receive our 5th safety award, and we are proud to be recognized for our commitment to employee safety and well-being. If you’ll be there, we’d love to connect.
