Expanded Mesh Filter Core Tube Machine

The PLC control system manages strip feed rate, forming pressure, and roller alignment to produce tubes with uniform diameter and straight seam registration. GCr15 bearing steel rollers, hardened to HRC 58–62, maintain tight tolerances even during extended production shifts, reducing reject rates and downstream quality issues in filter element assembly.

A single machine covers tube diameters from 130mm to 420mm, supported by over 300 mould sets available from NTBOBO’s tooling inventory. This range allows filter manufacturers to produce core tubes for compact inline filters through large industrial cartridge housings without investing in separate equipment for each size.

The round roller shear mechanism produces smooth tube ends without the jagged edges typical of straight-blade cutters. This eliminates the need for deburring stations, reduces the risk of damage to filter media during assembly, and lowers workplace noise levels on the production floor.

The control panel provides clear parameter display and adjustment for strip speed, tube length (up to 3000mm), and production count. The 4.0KW motor keeps energy consumption low relative to output. Lightweight forming moulds speed up diameter changeovers, reducing downtime between production batches.

The enclosed steel base housing protects drive components and pneumatic lines from dust and debris common in metalworking environments. At 1500kg, the machine is stable during high-speed operation, and its compact 1.8m length allows placement alongside fin stamping, tube expanding, or cartridge assembly stations in a complete filter production line.
