Sometimes the smallest changes can lead to the biggest improvements. That’s exactly what happened at a family-owned die casting company in Michigan when they decided to tackle a persistent production problem.
For 40 years, the company had been using regular municipal water to control mold temperatures in their die casting machines. While this traditional approach worked, it came with significant drawbacks: mineral deposits built up in the channels, temperature control was inconsistent, and production delays were frequent.
The solution? Switching to a Mokon HTF hot oil temperature control unit. The results speak for themselves:
- Production doubled from 600 to 1,200 units per eight-hour shift
- Quality improved dramatically with better surface finishes
- Restart times after stuck castings dropped from 25 minutes to just 5
- Mineral deposit buildup became a non issue
“Basically, the difficulties are the result of an inability to adequately control the die temperature with city water,” explained the company’s engineering president. The new system solved this core issue by providing precise temperature control throughout the casting process.
The success of this switch was so convincing that the company is now planning to convert all their remaining water-cooled systems to Mokon heat transfer fluid systems.
