At NFK Vietnam, using the technology and experience cultivated in Japan, we provide the high quality
products of Flexible Hose and Expansion Joint within short delivery time and reasonable price.
In-house integrated system
NFK Vietnam operates on an In-House Integrated System from raw material procurement to design, prototyping, and manufacturing. Since we do not outsource any process, we are superior to other companies in terms of quality control, cost, and delivery time.
Raw material assuranceSecuring raw materials
Other companies often start securing raw materials after receiving orders from customers. In that case, raw material price may change, or delivery time may be delayed due to shortage of raw materials. By contrast, NFK Vietnam always secures raw materials and stores in our own warehouse, so we can respond quickly to customer requests at any time.
Because of using an in-house integrated system and securing raw materials, we deliver in significantly shorter time than other companies. The requested products will be delivered at customer’s desired time.
Nangoku Flexible Hose Industry- the parent company of NFK Vietnam has been striving to improve quality for 50 years since established as a pioneer company of Flexible Hose, Expansion Joint. Currently, we are bringing the quality summed up in Japan into NFK Vietnam and receiving a lot of joy from customers.
SMALL ORDER SUPPORT
Flexible Hose and Expansion Joint are essentially made-to-order products because they are only required in certain locations and used for certain parts. NFK Vietnam can support small orders, handle quickly with only the required quantity.
What we have cultivated in Japan for more than 50 years is not only quality but also attitude towards customers. In other words, NFK Vietnam is not only a manufacturer, we accompany, support customers to approach their success.
Bellow Forming Machine
Roll-type bellows forming machineBellows are thin sheets of stainless steel (0.2 to 3.0 mm thick) that have been rolled into cylinders (of 25 to 2,000 mm in diameter), then corrugated by forming machine.
Bulge forming machine (up to 350A)Thin sheets of stainless steel (0.15 to 1.5 mm thick) are rolled into cylinders (of 17 to 350 mm in diameter), then corrugated by bulge forming machine.
Roll-type one-pitch spiral forming machineThin sheets of stainless steel (0.1 to 0.6 mm thick) are rolled into cylinders (of 3.5 to 65 mm in diameter), then corrugated by forming machine.
The Largest Braiding machine in Japan (up to 350A)In order to increase pressure resistance of Flexible Hose from φ8 to φ350, from stainless steel wires (φ0.3 ~ φ0.6), braid machine is used to create braid covering outside of tube.
Fully Automatic TIG Welding MachineFully Automatic TIG Welding Machine is used for welding general-purpose flexible tube from 20A ~ 100A.
Fully automatic precision welding machineFully automatic precision welding machine is used exclusively for welding flexible hose (semiconductor-related products made of thin sheets of 0.15 to 0.3 mm in thickness) for vacuum equipment and general vacuum lines.
Pressure Resistant / Airtight Testing machine
Immersion-type airtightness Testing MachineNFK uses an immersion-type airtightness Testing Machine to performs air leak tests on all products to prevent fluid leakage accidents.
Helium leak detectorBecause of its high sensitivity, helium leak detector is used for testing products in vacuum equipments related to semiconductors or vacuum pipelines in general. Permitted leak quantity: 1.33 × 10-10 Pa·m3/s
Other Durability testing Machine
Displacement testing MachineProduct durability is tested by displacing repeatedly the specimen in the direction perpendicular to the axis while applying pressure.YouTube
Vibration testing MachineProduct durability is tested by vibrating the specimen1,000 times per minute with a total amplitude of 0.3 mm (axial direction) or 0.6 mm (direction perpendicular to axis).YouTube
90 Degree Angle Bend Testing MachineBased on ISO - 10380 standard, product durability is tested by repeatedly bending the specimen at 90 degree angle.
U-Bend Testing MachineBased on ISO-10380 Standard, product durability is tested by repeatedly moving up and down one side of the specimen in U-shape.
