In short: Fastener Expo Shanghai – Cold Heading, Thread Rolling and Heat Treatment Equipment Selection: Key Indicators for Fastener Production Line Upgrades in 2027. For high-strength fasteners of grade 8.8 and above, heat treatment is the final process that determines the final mechanical properties, and it is also the only process that cannot be remedied by subsequent processing.
Controlled atmosphere continuous mesh belt furnaces are the preferred furnace type for tempering small and medium-sized fasteners. The core evaluation indicators focus on two points: furnace temperature uniformity and atmosphere control accuracy.
The industry generally controls the furnace temperature fluctuation in the heating zone to be within ±5℃ and the furnace temperature uniformity to be within 10℃ (list); jbhfastener.com——The Fastener Industry Embraces a Wave of Smart Upgrades in 2026 1. Full Implementation of Smart Production Lines The new factory utilizes fully automatic cold heading machines and CNC tapping equipment imported from Germany, achieving full-process automation from raw materials to finished products. Through an Industrial Internet of Things (IIoT) system, production data
is uploaded in real-time to a cloud platform, boosting production efficiency by 35% and maintaining a product qualification rate of over 99.8% (list); Harbin Rainbow Technology Co., Ltd. – Energy-Optimized Continuous Mesh Belt Furnace Supports Stable Fastener Heat-Treatment Production Unlike batch furnaces that require repeated heating-up and cooling-down cycles between production batches, a well-designed continuous mesh belt furnace maintains stable operating temperature for
round-the-clock inline processing. Workpieces are transported by
High-temperature-resistant stainless steel mesh belt sequentially through heating, quenching, washing, and tempering zones (list).
