Huichengsheng: On-Site Record of the Mesh-Belt Carburizing, Quenching, and Tempering Furnace for Screws

In the field of precision machining in the manufacturing industry, heat treatment processes are a critical link in enhancing the performance of parts. Leveraging its independently developed mesh-belt carburizing, quenching, and tempering furnace, Foshan Huichengsheng Furnace Industry Co., Ltd. provides efficient and stable heat treatment solutions to customers worldwide. Recently, the company completed the installation and commissioning of a customized production line for screws for a customer in Bangladesh, with the on-site operational data and process results receiving high recognition.

Technical Highlights: Full-Process Automation and Precise Temperature Control

The production line is designed with continuous mesh-belt operation as its core, integrating the three major processes of carburizing, quenching, and tempering into a single unit. The equipment features a lining of full-fiber refractory materials, combined with high-power circulation fans, ensuring that the temperature uniformity within the furnace is controlled within ±5°C, meeting the process requirements for thin-layer carburizing (≤0.3mm) of screws.

During the carburizing stage, the carbon potential is precisely regulated through a controlled atmosphere system, enabling the formation of a high-hardness carbide layer on the surface of the screws while maintaining toughness in the core. The quenching process employs stepped cooling technology to avoid the risk of cracking, while the tempering process utilizes low-temperature aging treatment to eliminate internal stresses and stabilize dimensional accuracy. The entire system enables automated material feeding, real-time monitoring of process parameters, and data traceability, with a single-line daily production capacity of up to 300,000 pieces.

Customer On-Site: Efficient Collaboration from Installation to Production Launch

The customer in Bangladesh is a well-known local fastener manufacturer that previously suffered from a product qualification rate of less than 80% due to outdated equipment. Based on the customer's production line layout and process requirements, the Huichengsheng team customized a compact mesh-belt furnace solution, reducing the equipment footprint by 40% compared to traditional pit-type furnaces, while integrating a post-cleaning machine and exhaust gas treatment unit to comply with local environmental standards.

During the installation and commissioning phase, the Huichengsheng engineering team remained on-site for 15 days to complete equipment calibration, process validation, and operator training. Through simulated production tests, the surface hardness of the screws reached HRC 60-62, with a uniformity error in carburized layer depth of ≤0.05mm. The customer's technical director commented, "The new equipment has tripled the wear resistance of our products and reduced the scrap rate to below 2%."

Industry Applications: Heat Treatment Experts for Standardized Parts

The mesh-belt heat treatment furnace series from Huichengsheng has been widely applied in mass production scenarios for standard parts, bearings, chains, self-tapping screws, and more. Its technical advantages are reflected in three key areas:

Material Adaptability: Capable of processing various materials such as carbon steel, alloy steel, and supporting composite processes like carbonitriding and bright quenching.

Energy-Efficient Design: Utilizes high-efficiency heating elements and waste heat recovery systems, reducing energy consumption by 15% compared to similar products.

Modular Structure: Supports on-demand expansion of units such as quenching oil tanks and cleaning machines, providing flexible adaptation to different production line requirements.

Currently, the company has delivered over 200 mesh-belt heat treatment furnace production lines to customers in more than 20 countries, including India, Pakistan, and Mexico.

Future Outlook: Driven by Intelligence and Globalization

As the trend of Industry 4.0 deepens, Huichengsheng is advancing the digital upgrading of its heat treatment equipment. Its next-generation mesh-belt furnaces will integrate an AI process optimization system, automatically adjusting temperature curves and atmosphere parameters through machine learning to further reduce energy consumption and manual intervention.

From the screw production line in Bangladesh to industrial sites worldwide, Huichengsheng Furnace Industry is redefining the value standards of heat treatment equipment through technological innovation—not only providing hardware but also delivering stable, efficient, and sustainable manufacturing solutions.
