Screws, bolts, and fasteners are the foundation of almost every industry—automotive, construction, household appliances, machinery, and electronics. To guarantee strength, hardness, reliability, and long-term durability, these components must undergo precise and stable heat treatment.
A continuous mesh belt furnace is the preferred solution for large-volume screw and fastener production. It ensures consistent quality, high efficiency, and automatic operation—making it an essential piece of equipment for modern fastener factories.
So what makes mesh belt furnaces the top choice? And what do customers learn when they visit our factory?
Let’s take a closer look.
1. Why Do Screws Need Heat Treatment?
Screws and fasteners experience significant mechanical stress during use. Without heat treatment, they cannot achieve the required hardness or strength.
Heat treatment improves:
Tensile strength
Hardness and wear resistance
Fatigue performance
Toughness
Dimensional stability
Long-term durability
This is especially important for automotive screws, structural bolts, and precision fasteners used in safety-critical applications.
2. What Makes a Mesh Belt Furnace Ideal for Screw Heat Treatment?
A mesh belt furnace provides continuous, automated, and uniform heat treatment, making it suitable for high-speed, high-volume fastener production.
Key advantages include:
Fully automatic feeding & discharging
High production capacity
Stable temperature uniformity
Consistent heat treatment results
Continuous carburizing, quenching, or tempering
Reduced labor cost
Perfect for mass production
It allows screws to move through the furnace smoothly on the mesh belt, ensuring each piece receives identical heating and cooling conditions.
3. Suitable for Various Fastener Heat Treatment Processes
Our mesh belt furnaces can perform:
Carburizing
Carbonitriding
Hardening and quenching
Tempering
Bright normalizing
Stress relieving
This makes them widely used in:
Self-tapping screws
Hex screws
Machine screws
Bolts and nuts
Precision fasteners
Alloy steel and carbon steel screws
The system offers complete flexibility for different materials and hardness requirements.
4. Atmosphere Control for High-Quality Results
To ensure consistent and stable metallurgical results, the furnace is equipped with precise atmosphere systems:
Endothermic gas
Nitrogen
Methanol cracking gas
Protective mixed gases
This guarantees:
Controlled carbon potential
Stable carburizing depth
Clean, bright surface
Reduced oxidation
High mechanical performance
Customers can also choose dew-point control and automatic gas supply options.
5. Energy-Efficient and Durable Structural Design
Our screw mesh belt furnace is engineered to reduce long-term costs through:
High-quality insulation materials
Optimized heating elements
Energy-saving combustion or electric heating
Stable mesh belt transmission
Long-lifespan furnace lining
Automatic control system
The furnace operates 24/7 with minimal maintenance requirements—ideal for factories with continuous production.
