Commitment to Quality
A working partnership for exceeding customer expectations.
At Thermtrol, quality is more than a process, it's our culture. We engineer every process with precision and build every assembly with care, ensuring your specifications are not just met, but exceeded.
Our thoughtfully designed Quality Management System (QMS) is certified to the internationally recognized standards of ISO 9001 (since 2000), ISO 14001 (since 2015), and IATF16949 (since 2019), and we follow the Advanced Product Quality Planning (APQP) process to define every step required for success. This ensures proactive risk mitigation and repeatable, documented quality protocols and provides you with a dedicated development team to assist with planning, practicability, prototype development, testing, and the Production Part Approval Process (PAPP)
As a Thermtrol partner, this means you will have a knowledgeable manufacturing resource with proven expertise and advanced capabilities committed to supporting you.
Advanced Testing and Validation.
To support our mission, Thermtrol has invested over $1.5 million in cutting-edge quality testing systems in addition to our advanced knowledge in wire processing, crimp technology and over molding. Equipment includes:
Environmental Chambers to ensure performance and dependability under various simulated environmental conditions.
Dynalab and Cirris Cable Testers to verify electrical connections.
Motorized Pull-Force Monitoring to ensure reliability and harness safety.
Temperature Rise Testing to ensure low resistance of terminal and wire combination.
Press Force Analyzers to ensure structural integrity and assembly precision.
On-floor Cross-Section Crimp Testing to optimize crimping parameters and identify early defects.
In addition, our Push-Click-Pull™ method guarantees terminal seating with 100% verification, using custom-built, Poka-Yoke-equipped fixtures that eliminate guesswork and human error.
Built for Reliability
We don’t rely on end-of-line inspections alone. Our team performs in-line validation and real-time monitoring throughout production—ensuring consistency, compliance, and performance shift after shift. Whether you're building HVAC systems, automotive assemblies, or industrial equipment, you can rely on Thermtrol for proven, repeatable results.
Our commitment to excellence is backed by world-class quality systems incorporating Six Sigma methodology, TVR reports, press analyzers, and a comprehensive BBMX system. These are all supported by cutting-edge technical labs and a quality-driven culture at every level of our organization.

Engineering and Development Assistance
Thermtrol supports all phases of design and engineering of new wire harnesses
and over molded products.
There are three major steps in development
-
Step 1Conceptual configuration to determine the relative dimensions needed.
-
Step 2Pre-production design proof of the proper form to be used in manufacturing.
-
Step 3Manufacturing and pre- production test-runs to support testing and prove manufacturing process prior to full-scale production.
In addition, we offer timely and cost-effective evaluation of your existing or planned custom wire harness assembly and overmolding needs. Thermtrol customers rely on our engineering assistance to redesign components and help them maximize product reliability, simplify installation and streamline their supply chain.
