lidingWhy choose this machine?
Affordable entry-level, fast return on investment
-
We designed this machine specifically for small factories and startups. It’s priced competitively without cutting corners on quality. It replaces 3-4 manual workers, cutting your labor costs by 70%. Most of our customers recoup their investment in 8-12 months.
-
22 sets of precision rollers ensure consistent and stable blade quality
-
The 22 sets of rollers (16 front sets for forming + 6 rear sets for interlocking) are made of Cr12MOV steel with a hardness of HRC 57°–59°, whilst the cutting dies have a hardness of HRC 60°–62°. The upper and lower profiles interlock precisely, resulting in a hollow structure with high rigidity and excellent torsional resistance. The finished blades fit tightly onto a 12×12 mm square shaft, ensuring precise, wobble-free transmission.
-
Synchronised feeding of two coils, with upper and lower sections joined in a single forming operation
-
The upper coil forms the upper half, whilst the lower coil forms the lower half; these are then precisely joined in the final forming module to create a complete hollow blade, eliminating the need for subsequent riveting. The equipment operates continuously and automatically, enhancing production efficiency and reducing overall costs.
-
12-month warranty + pre-delivery testing
-
Each unit undergoes comprehensive line-integration testing prior to dispatch. Complete technical documentation (installation drawings, circuit diagrams, operating manual) is provided. A 12-month warranty covers free replacement of spare parts, alongside lifetime online technical support, ensuring worry-free production for our customers.
-
Standard Production Process
-
Synchronised unwinding from dual unwinders → Front-end forming (8 upper stations + 8 lower stations) → Transition guide → Joining and forming (6 clamping stations) → Hydraulic Cutting → Finished Product Run-out Table
