A 230-meter-long, 1.5-meter-wide Mingke carbon steel belt has been operating continuously and reliably for three years in a FRANZ HAAS tunnel oven at a cookie production facility in Suzhou, built by a leading multinational food company.This successful long-term operation under demanding conditions is a strong testament to the durability and performance of Mingke steel belts. More importantly, it reinforces global confidence in China’s high-end manufacturing capabilities as we continue to expand into international markets.

• Project Background: Chosen by a Global Industry Leader, Surpassing Technical Barriers

The project is located in Suzhou Industrial Park and was invested in by a globally renowned food manufacturer. Designed as the central baking hub for the Asia-Pacific region, the production line features a FRANZ HAAS tunnel oven, a leading European brand known for its stringent performance standards.

The steel belt, a critical component of the tunnel oven, must meet demanding requirements for flatness, heat resistance, and wear durability. With its custom-engineered carbon steel and precision manufacturing, Mingke’s steel belt was selected as a key component of this high-performance production line.

• Technical Challenge: Tackling the “High-Temperature Battle” of Cookie Baking

The performance of the steel belt in cookie production is tested in two critical areas:

1.Thermal Stability:
During the baking process, the steel belt must withstand continuous exposure to temperatures around 300°C, while maintaining a perfectly flat surface without deformation.
Mingke enhances belt strength and thermal stability through in-oven heat treatment, ensuring long-term operation without thermal distortion. This guarantees uniform coloring and consistent shaping of the cookies.

2. Reliability Over Ultra-Long Lengths:
At 230 meters in length, the steel belt must overcome challenges related to transverse welding strength and longitudinal stress distribution.
Mingke addresses these issues with automated welding technology and a precision tension-leveling process that eliminates internal stress, resulting in smooth, vibration-free operation throughout the production cycle.

• Industry Significance: Accelerating Mingke’s Globalization Journey

1.Technical Validation:
The long-term, stable use by a global food giant serves as strong validation of Mingke steel belts’ reliability in high-temperature baking applications.

2.Breakthrough in International Market Entry:
With successful installations in over 20 countries and regions, this project acts as a strategic gateway for Mingke to penetrate the global baking equipment supply chain—particularly by laying the groundwork for deeper cooperation with top-tier OEMs like FRANZ HAAS.

3.Benchmark for Domestic Substitution:
High-end food production lines have long relied on imported steel belts. This project demonstrates that Chinese-made steel belts can now deliver breakthrough performance in ultra-wide, ultra-long, and high-temperature baking environments, setting a new benchmark for domestic alternatives.

• Mingke strength: the “invisible champion” of steel belt manufacturing

Mingke’s Core Strengths Behind This Breakthrough:

1.Dual Barriers of Material and Process:
Carefully selected steel combined with integrated tunnel heat treatment technology enhances flatness and stability under high-temperature conditions.

2.Customization Capability:
Tailored solutions based on customer requirements, with applications spanning wood-based panel, food, rubber, chemical, and new energy industries.

3.Global Service Network:
Service centers established in over 10 countries including Poland and Australia, offering comprehensive support throughout the entire lifecycle—installation, welding, maintenance, and more.

The success of Mingke steel belts in the Suzhou project for a global food leader represents not only a technological triumph for “Made in China,” but also marks the elevation of domestically manufactured core components within the global food industry supply chain.

Looking ahead, Mingke will continue to leverage its steel belts as a platform to drive the globalization of “Made in China” across baking, wood-based panel, new energy, and other sectors—showcasing the robust strength of Chinese steel belts to the world.
