Exciting News — A New Project Is Now Under Development!
We are thrilled to announce that Frand is actively developing a brand-new machine — the Double-Wire Hose Clamp Assembly Machine. This project represents an exciting expansion of our product portfolio and a significant step forward in our commitment to providing comprehensive automation solutions for the hose clamp industry.
We warmly welcome inquiries from customers, partners, and industry professionals who are interested in this new machine.
What Is a Double-Wire Hose Clamp?
Before introducing the machine, it is important to understand the product it will produce.
The double-wire hose clamp (also known as a twin-ring wire clamp or spiral double-wire clamp) is a specialized type of hose clamp that uses two parallel loops of steel wire — rather than a single flat band — to provide clamping force around a hose or pipe connection.
Compared to conventional flat-band worm gear clamps, double-wire hose clamps offer distinct advantages:
Advantage | Description |
More uniform clamping pressure | The twin-wire design distributes clamping force evenly around the entire circumference of the hose, reducing the risk of localized deformation or hose damage |
Higher structural rigidity | Two parallel wire loops provide greater resistance to deformation under high-pressure and high-vibration conditions |
Superior sealing performance | The even pressure distribution creates a more reliable, leak-proof seal — critical in applications where fluid integrity is paramount |
Greater durability | Double-wire clamps are less likely to deform, loosen, or fail under long-term use, vibration, or thermal cycling |
High reusability | The design allows for repeated installation and removal without loss of clamping performance |
Applications of Double-Wire Hose Clamps
Double-wire hose clamps are widely used across industries that demand reliable, high-performance hose connections:
- Automotive — coolant hoses, fuel lines, turbocharger connections, and emissions systems where vibration resistance and consistent clamping force are critical;
- Marine — seawater cooling systems, bilge pump connections, and fuel lines where corrosion resistance and sealing integrity are essential;
- Industrial plumbing and HVAC — large-diameter hose and pipe connections in commercial and industrial fluid transport systems;
- Agricultural machinery — irrigation systems, spraying equipment, and fluid transfer lines;
- Chemical processing — connections requiring reliable seals under pressure and exposure to aggressive media.
Material and Specifications
Double-wire hose clamps are manufactured from a range of materials to suit different application environments:
Material Grade | Corrosion Resistance | Typical Application |
W1 — Galvanized steel | Basic | General-purpose indoor and dry environments |
W4 — AISI 200/300 series stainless steel | Good to excellent | Automotive, industrial, and outdoor applications |
AISI 316/316L stainless steel | Superior | Marine, chemical, and highly corrosive environments |
Available specifications include:
- Clamp diameter range: approximately 10 mm to 178 mm (covering a wide range of hose sizes)
- Wire diameter: 1.5 mm to 3.0 mm (depending on clamp size)
- Fastener: M5 to M8 bolt/screw with hex drive for installation and adjustment
The Double-Wire Hose Clamp Assembly Machine — What to Expect
Frand's new Double-Wire Hose Clamp Assembly Machine is being engineered to automate the complete assembly process for double-wire hose clamps — from wire feeding and forming through housing assembly, screw engagement, and finished product output.
Expected Assembly Speed
Parameter | Target |
Assembly speed | Approximately 800 pieces per hour |
While this speed is lower than our flat-band assembly machines (which achieve 1,000–1,200 pcs/h), it reflects the inherently more complex assembly process required for double-wire clamps — including precision wire forming, dual-loop positioning, housing attachment, and screw engagement with two parallel wire loops.
At 800 pieces per hour, the machine is designed to deliver efficient, consistent, and reliable production that far exceeds any manual or semi-automated assembly approach for this clamp type.
Key Design Principles
The machine is being developed according to Frand's established engineering standards:
- Full automation — from component feeding through finished product output, the entire assembly process runs automatically with minimal operator intervention;
- PLC-controlled precision — all assembly parameters (wire forming, positioning, riveting, screw engagement) are controlled by our proven PLC platform for consistent, repeatable quality;
- Quick changeover — programmable recipe management will enable rapid switching between different clamp sizes and wire diameters;
- Integrated quality inspection — the machine will incorporate in-line inspection capabilities to verify assembly quality on every unit produced;
- Customizable configuration — as with all Frand machines, the Double-Wire Hose Clamp Assembly Machine will be configurable to meet specific customer requirements for clamp sizes, materials, and production volumes.
Why This Machine Matters
The double-wire hose clamp is a growing segment of the hose clamp market — driven by increasing demand for higher-performance clamping solutions in automotive, marine, and industrial applications. However, the assembly of double-wire clamps has traditionally been a labor-intensive, difficult-to-automate process — resulting in higher production costs, lower output, and inconsistent quality.
Frand's new machine is designed to solve this challenge — bringing the same level of automation, precision, and efficiency that we have already delivered for flat-band hose clamp assembly to the double-wire clamp segment.
This machine will enable manufacturers to:
- Reduce production costs — automate a process that has historically required significant manual labor;
- Increase output — produce 800 finished clamps per hour with consistent quality;
- Improve product consistency — eliminate human variability from the assembly process;
- Meet growing market demand — scale production to serve the expanding double-wire clamp market;
- Gain competitive advantage — be among the first manufacturers to adopt fully automated double-wire clamp assembly technology.
Project Status and Timeline
The Double-Wire Hose Clamp Assembly Machine is currently in active development. Our engineering team is finalizing the design, prototyping key assembly stations, and refining the machine's control systems.
We anticipate that the machine will be ready for customer demonstrations and sample production in the near future.
