Why Choose Our 2 Die 4 Blow Bolt Makers from China & Taiwan?
The FMT high-speed two die four blow screw making machine is a cornerstone of modern fastener production in China and Taiwan. It excels where traditional multi-station bolt makers struggle, particularly with large-head-to-short-shank ratios.
Below are the top 4 advantages of choosing our 2 die 4 blow screw maker technology:
1. Versatile Production of Non-Standard Fasteners
Our machine can produce a vast array of products, from ordinary screws and internal/external hex bolts to high value-added special-shaped parts. This includes fully tubular long pull screws, flange bolts, multi-step screws, and semi-tubular rivets. It is the ultimate tool for non-standard fastener parts that require precision and flexibility.
2. High Cost-Efficiency vs. Multi-Station Machines
Compared to a 4-station, 5-station, or 6-station bolt making machine, the 2 die 4 blow screw making machine costs approximately 50% less. This allows manufacturers to stay agile, managing production plans and small-batch orders without the heavy capital investment or the need for the highly specialized operators required by complex progressive machines.
3. Superior Handling of Large Material Deformation
This bolt maker is specifically optimized for products with large material deformation (big heads) and multiple steps on the shank. As the global market demand for personalized customization and non-standard parts increases, the 2D4B machine provides the technical solution for parts that even 6-station machines cannot easily produce.
4. Low Tooling Costs for Small Batch Orders
While multi-station bolt makers carry high die and tool expenses, the 2 die 4 blow screw maker keeps tooling costs low. This significantly improves the input-output ratio for small-batch customized orders, ensuring you can fulfill niche customer demands profitably without the risk of high overhead.
