The industrial equipment manufacturing sector in North America has strict requirements for heating elements: they must maintain stability during high-frequency production, and control energy consumption effectively.
A U.S. industrial drying equipment company based in Ohio faced production troubles due to heating tube issues. Its core product is assembly lines for drying auto parts. The local-brand heating tubes it previously used started failing after just 3 months:
- Heating efficiency dropped sharply – drying time lengthened from 20 minutes to 35 minutes, cutting production line efficiency by nearly 40%.
- Some tubes corroded and had excessive leakage current, triggering safety alarms repeatedly and forcing production shutdowns for repairs.
The company got no effective solutions after communicating with its original supplier, leaving the cooperation at an impasse.
Later, the company's procurement manager met Hongtai at an industry exhibition and clearly stated its core needs:
- Adapt to North America's 110V voltage, with a single-tube power of 3000W.
- Stabilize the drying chamber temperature at 180℃ within 15 minutes, with a temperature error ≤ ±5℃.
- The tube shell must resist high-temperature grease and mild corrosion, with a continuous service life ≥ 5000 hours.
- The product must meet U.S. industrial equipment access standards.
Hongtai's sales and technical team analyzed the needs on-site, provided a preliminary solution, and demonstrated test data of its similar-series products. They also confirmed details like the client's equipment working conditions, production rhythm, and voltage fluctuation range. Just 10 days later, Hongtai produced 3 sets of samples and sent them to the U.S. via international express.
The client's on-machine testing showed the samples fully met requirements:
- Under 110V voltage, the temperature reached 180℃ and stayed stable between 178℃ and 182℃ during 48 hours of continuous operation.
- Leakage current was far below the limit set by UL standards.
- The 304 stainless steel shell showed no corrosion after salt spray testing.
- The built-in overload protection device handled voltage fluctuations, avoiding equipment damage risks.
After the test, the client placed an order for 500 heating tubes and requested custom engraving of equipment numbers on the tubes. Hongtai completed production on schedule, and along with the products, provided complete UL certification reports and product testing records. It also arranged technicians to guide the client's workers through installation and commissioning via video.
Since the tubes were put into use:
- The production line's efficiency returned to normal.
- No safety alarms were triggered by heating element issues.
- The client's financial calculation showed that the cost of purchasing the tubes could be recovered in just 6 months, solely from reduced losses caused by production shutdowns.
To date, the first batch of heating tubes has operated stably for nearly a year, with all performance indicators remaining good and no failures reported.
For the North American market, Hongtai always focuses on compliance and stability, providing solutions tailored to clients' actual production pain points. This cooperation proves that with product quality meeting international standards and efficient end-to-end services, Hongtai is fully capable of meeting the strict demands of North American industrial clients – and this is the key to its recognition in the North American market.
