Kainuo is one of the country's leading experts in hose clamps, stainless steel no-hub couplings, and custom molded rubber parts. We are a privately owned company and supply customers around the world.
Our workforce, more than 1200 strong, operates from a 400,000-square-meter manufacturing facility. 40% of our offerings are geared towards the domestic market, while the rest of them ship out to customers across the globe.
By involving ourselves in every step of the manufacturing process, from developing tools and dies to producing hose clips, hubless couplings and flexible rubber parts, we have formed a complete supply line, able to cater to customers' differing needs. We own and operate out of 10 workshops dedicated to producing quality products with quality second to none. A typical day of operation yields up to 1 million hose and pipe fasteners.
Outfitted with 26 riveting machines, the assembly workshop is where around 3 million hose clamps are produced on a monthly basis. Her in this job shop, skilled workers piece together the screw housing and steel band using the riveting machine.
In our plate bending workshop, we use 8 punch presses and plate bending machines to roll steel plates into a ring shape forming what is called the steel band. The entire process is fully automated for improved productivity. Monthly yield: 3 million items.
Additionally, we've introduced 8 automatic forming machines, each providing multiple working stations to complete the production of spring hose clamps in one step. Every month, we produce 1.6 million spring steel hose clips using that equipment.
1. Wire-Cut EDM
2. Machining Center
There are 2 sets of machine centers that can handle complex parts all while achieving close geometric tolerance of up to 0.01mm. Again, the process is automated, allowing quick change of tools.
We use vertical lathes to cut the internal size of the wheel case to precision up to ±0.01mm. High stability allows the equipment to work on various irregular shapes.
With a monthly production rate of around 600,000 to 700,000 hubless couplers, this job shop adopts advanced process flows and strict quality control measures to guarantee customers receive only the best non-hub couplings.
1. Cold Glue Production
2. Injection Molding
The 23 injection molding machines are used to produce rubber components for use in the construction of flexible rubber couplings. This in-house manufacturing capability saves production cost, allowing us to produce 1.1 to 1.2 million rubber parts.
This workshop turns out approximately 3 million hose clamps every month. Main products include the 2-ear clamp, high-strength hose clamp, T-bolt clamp and more.
With over 70 employees on staff, this workshop mainly manufacturers hubless couplings with a monthly production rate of 500,000pcs.
This workshop is staffed by approximately 200 employees and produces different German style hose clamp configurations in stainless steel and iron. We can do 10 million hose clamps per month.
We've got 3 barrel plating lines where small size hose clamp parts can be coated with zinc. No manual operation is needed. A computer controls the PH value, plating time and temperature to ensure the zinc coating spreads out evenly on the surface of parts to be coated.
