I have been with Stanadyne for close to 40 years and never experienced the service and commitment that we get from Thermal. Over the last three years we have moved a lot more of our heat treat business, cleaning operations, & mag phosphate operations to Thermal. The PPAP process was handled very professionally and thorough. The customer service team has been outstanding—daily communication and timely responses to our questions or concerns.
