Spring Temper Furnace Manufacturer

What role does the spring tempering furnace play in the R&D system of WNJ?
A: It is considered the final "invisible process" connecting forming and service performance. When designing the spring machine, the company's mold workshop incorporates the furnace's hot zone layout, airflow direction, and fixture interfaces as part of the overall solution, ensuring that any irregularly shaped spring from OEM/ODM customers can complete the entire closed-loop process from winding to tempering on the same production line.

Why does WNJ insist on "integrated furnace and machine" instead of purchasing standard furnaces?
A: Because the temperature control curve of the tempering furnace is closely coupled with the cycle time, wire diameter, and material changes of the spring machine. The in-house mold workshop can design the furnace support fixture, conveyor cycle wheel, anti-deformation chuck, and winding spindle coaxially, avoiding the redistribution of residual stress caused by secondary clamping, which is especially crucial for high-precision orders.

How does the temperature uniformity of the tempering furnace amplify the mutual enhancement of WNJ's mold precision?
A: When processing the positioning blocks, the mold workshop allows for micron-level thermal expansion compensation; the furnace engineers, in turn, control the temperature difference in the hot zones within a corresponding range. When combined, the same set of springs exhibits consistency in length, load attenuation, and anti-relaxation performance, reducing the frequency of spot checks for customers undertaking large-scale OEM production.

How does WNJ help customers shorten the trial production cycle for new products through tempering furnaces?
A: The mold workshop can complete rapid fixture iteration within 24 hours; the temperature control system of the tempering furnace shares the same bus with the servo drive of the winding machine. Engineers only need to program once when debugging new springs, and the coupled parameters of temperature, speed, and tension can be simultaneously issued, eliminating the need for repeated fixture disassembly and reassembly or production line transfers during the trial production stage.

How is the energy-saving concept of the tempering furnace integrated into WNJ's green manufacturing strategy?
A: The furnace body insulation module and the winding machine's cooling circuit share a heat recovery channel. The mold workshop prioritizes lightweight, low-heat-capacity materials when designing fixtures, reducing energy waste during furnace temperature rise and fall, allowing OEM/ODM customers to pursue high performance while considering carbon emission standards.

How does the tempering furnace respond when customers request special alloys or extremely small wire diameters?
A: WNJ's mold workshop first manufactures miniature clamping fixtures and low-inertia conveyor rollers. Tempering furnace engineers then adjust the hot zone length and airflow speed to ensure that the delicate springs do not deform due to their own weight or airflow disturbances during tempering, ultimately allowing for stable output even at extreme specifications within mass production.

How does the tempering furnace's remote maintenance function connect with WNJ's global service network?
A: The furnace control system and winding machine servo data share the same cloud channel. Overseas customers' on-site engineers can simultaneously view furnace temperature curves and winding parameters by logging into a unified interface. The mold workshop's spare parts warehouse pre-disassembles easily damaged fixtures into quick-change modules, allowing for replacement within 48 hours of air transport, reducing downtime anxiety.

How does WNJ use tempering furnace data to reverse-engineer mold design?
A: The residual stress distribution after each tempering is recorded by the system. After comparing the deformation trends of the same batch of springs, mold engineers fine-tune the support points and clamping force of the next version of the fixture. This closed-loop system allows OEM orders to reduce the post-tempering shaping process during the second round of production, directly improving the first-pass yield.

How does the safety interlock logic of the tempering furnace align with the production line safety level of WNJ?
A: The triggering conditions for furnace door lifting, atmosphere replacement, and quench spraying share the same safety PLC as the winding machine's emergency stop, access control, and light curtain. The mold workshop also reserves escape clearances and explosion-proof pressure relief channels when designing fixtures, ensuring that any single-point failure will not amplify into a cross-equipment risk.

What is WNJ's iterative approach to tempering furnaces for the future?
A: The mold workshop is experimenting with a reconfigurable hot zone structure, enabling the same furnace body to switch between long and short spring production lines within ten minutes; the tempering furnace team is exploring real-time mapping of three-dimensional data of temperature, atmosphere, and stress fields into a digital twin model, allowing remote engineers from OEM/ODM customers to "drag" the tempering curve like debugging software, verifying new product performance in a WYSIWYG manner.
