Rainbow, a trusted manufacturer specializing in heat treatment screws, bolts, fasteners, and advanced mesh belt furnace systems, announced today the expansion of its production capacity and technological upgrades, reinforcing its position as a one-stop solution provider for industrial fastener heat treatment and related equipment. As the global demand for high-performance, durable fasteners continues to rise—driven by infrastructure development, automotive manufacturing, and renewable energy projects—Rainbow’s investment in state-of-the-art mesh belt furnace technology underscores its commitment to meeting industry standards and client needs.
A mesh belt furnace is a critical piece of equipment in the heat treatment process for screws, bolts, and fasteners, enabling continuous, uniform thermal processing that enhances product strength, hardness, and corrosion resistance. Rainbow’s newly upgraded mesh belt furnace systems integrate advanced PLC control, Scarda, HMI, controlled atmosphere technology, and energy-efficient heating elements, ensuring consistent heat treatment results for a wide range of fastener products, from standard industrial bolts to custom-engineered heat treatment screws used in high-stress applications like pressure vessels and aerospace components.
“The quality of heat treatment directly determines the performance and reliability of screws, bolts, and fasteners—especially in industries where safety and durability are non-negotiable,” said a spokesperson for Rainbow. “Our advanced mesh belt furnace systems are designed to address the core needs of fastener manufacturing: consistent quality, high throughput, and compliance with international standards. By optimizing our mesh belt furnace technology, we can deliver heat treatment screws and bolts that meet the strictest mechanical property requirements, including tensile strength exceeding 860MPa for high-performance applications.”
Rainbow’s mesh belt furnace line is tailored specifically for fastener heat treatment, supporting processes such as quenching, tempering, annealing, and carburizing—key steps in enhancing the mechanical properties of screws, bolts, and fasteners. The continuous conveyor design of the mesh belt furnace allows for large-volume production, with standard models capable of processing 200 to 500 kg of fasteners per hour, while customizable options are available for higher-capacity needs. The controlled atmosphere within the furnace prevents oxidation and decarburization, ensuring the surface quality and structural integrity of each heat treatment screw and bolt leaving the production line.
In addition to its mesh belt furnace systems, Rainbow provides a full range of high-performance machines for fastener production, including screw making machine, bolt maker, thread rolling machine, nut forming machine, nut tapping machine, cold forging machine, cold heading machine, rivet making machine, and other fasteners machines. These specialized machines are engineered with precision to support efficient, large-volume fastener manufacturing, leveraging advanced automation and CNC machining technologies to ensure consistent quality and high productivity. Rainbow’s fastener production machines are highly sought after for their stability, easy operation, and customizable capabilities, making them ideal for manufacturers in automotive, construction, oil and gas, and renewable energy sectors that require reliable equipment to produce high-quality fasteners.
Industry data highlights the growing importance of advanced heat treatment equipment and high-quality fasteners: the global heat treatment equipment market is projected to reach $142 billion by 2028, with a CAGR of 6.2%, driven by demand for reliable thermal processing in fastener manufacturing. Meanwhile, the global fastener market is expected to grow steadily, with heat treatment screws and bolts playing a critical role in supporting infrastructure megaprojects and advanced manufacturing trends. Rainbow’s dual focus on mesh belt furnace technology and high-quality fasteners positions the company to capitalize on this growth, serving clients in over 20 countries across Asia, Europe, and North America.
“Rainbow’s strength lies in our ability to integrate advanced mesh belt furnace technology with expert fastener manufacturing,” added the spokesperson. “We don’t just sell mesh belt furnace systems or heat treatment screws—we provide end-to-end solutions that help our clients improve production efficiency, reduce costs, and deliver superior products to their own customers. Our ongoing investment in R&D ensures that our mesh belt furnace technology and fastener products remain at the forefront of industry innovation, aligned with 2026 trends such as intelligent automation and materials advancement.”
To support its expanded capabilities, Rainbow has also enhanced its after-sales service for mesh belt furnace systems, offering installation, maintenance, and technical support to ensure optimal performance. The company’s team of engineers has extensive experience in fastener heat treatment and mesh belt furnace operation, providing customized solutions to meet the unique needs of each client.
