If you are in the business of making unknotted fishing nets, I'm sure you have encountered situations where an entire batch of nets was scrapped due to a single thread breaking halfway through, and entire shipments of exports were rejected because the mesh sizes between the rolls differed by a few millimeters. The fishing net industry never compensates for "almost" - it rewards uniform mesh sizes, reliable equipment, and uninterrupted production. And this is precisely why Changzhou Longlongsheng Industrial Weaving Machinery Co., Ltd. has become a top player in the field of unknotted fishing net machines. This is not another equipment manufacturer boasting about parameters on a sheet. Longlongsheng's reputation has been verified by one after another net fabric factory through actual production - it relies on equipment specially designed to meet the unique requirements of unknotted fishing net weaving. This article will dissect why general knitting machines cannot make fishing nets well, what characteristics a truly top-notch net machine manufacturer possesses, and the actual performance of Longlongsheng equipment in real factories. If you are still troubled by malfunctions, defective products, and downtime, this article is worth your reading.
Let’s start with a hard truth most machinery vendors won’t tell you: most warp knitting machines are not built for fishing nets. They’re built for soft fabrics, lace, sportswear and light decorative mesh. Fishing net production is a completely different beast – it’s heavy load, high tension, thick monofilament yarn, and runs 24 hours a day. Using a general-purpose machine for fishing nets is like wearing a running shoe to climb a mountain – it might work for a little while, but it will break down fast, and it will never perform the way a purpose-built tool does.
Most factory owners only look at the upfront price tag when they buy a machine. But the real cost of a cheap generic machine lives in the quiet, daily profit leaks that add up month after month. If you’re running generic machines, you’re almost certainly losing money in two places you might not even be tracking closely.
Thick PP and PE monofilament yarns for fishing nets put massive stress on needles, cams and yarn feeders. Generic machines use lightweight parts designed for fine polyester yarn. Run heavy fishing net yarn through them, and yarn snaps become a daily – even hourly – occurrence. Every break means a stop, a knot, a weak spot in the net, and often a section of finished product that goes straight to the scrap pile. Do you know how much money you throw away every month on scrap netting from preventable yarn breaks? For most factories, it’s far more than the price difference between a generic machine and a professional one.
The second silent killer is inconsistent mesh size. Generic machines have basic tension control that works fine for soft fabric, but can’t hold steady under the heavy pull of fishing net monofilament. Mesh sizes drift, knot tension varies, and the finished net doesn’t meet the exact specifications buyers require. For export orders, that means inspection failures, price deductions, or rejected entire containers. In this business, consistency isn’t a luxury – it’s the price of keeping your customers.
Anyone can call themselves a fishing net machine manufacturer. Very few actually earn the title. After working with hundreds of net factories across the world, we’ve settled on two non-negotiable benchmarks that separate the top players from the rest.
Top players don’t split their R&D budget across a dozen different fabric types. They pour all their engineering effort into net weaving technology, knot formation, monofilament handling and heavy-load machine design. They have patents for net-specific systems, and their engineering teams eat, sleep and breathe mesh production.
A true top player doesn’t just sell one net machine. They have a full lineup for every net type, gauge and width – from light agricultural shade nets all the way up to heavy deep-sea fishing trawl nets. If a supplier only has one “net model” and tries to tell you it does everything, that’s your sign to walk away.
Here’s the simple reason universal machines never work long-term for fishing nets: every part of the machine is a compromise. The frame is lighter to save cost, the cam system is tuned for light loads, the tension control is built for fine yarn. Every compromise adds up to more breaks, more defects and more downtime. For a hobby shop that runs a few hours a week, that might be fine. For a commercial export factory running 24/7? It’s a losing bet every single time.
So where does Changzhou Longlongsheng land on all those benchmarks? At the very top. Based in Changzhou – China’s warp knitting industry heartland – Longlongsheng has spent decades focusing on one thing and one thing only: building the best knotless raschel net machines in the world for industrial and agricultural net producers. Changzhou Longlongsheng has established since 1995.It is a high-tech enterprise specializing in the research, production, sales and service of warp knitting machine . It mainly produces various of fishing nets, sunshade nets, sports nets, protective nets, agricultural nets, safety building nets, mesh fabrics, swimsuits, fruit bags, blankets, towels, shoe materials, mattresses, car interiors, seamless underwear, medical nets, and so on.
Unlike those large-scale textile machinery brands that produce everything from sewing machines to carpet equipment, Longlongsheng has taken a specialized approach. More than 85% of our product lines are focused on net fabric production equipment. They are dedicated to solving problems in each field: reducing yarn breaks, improving consistency of knots, extending equipment lifespan, and increasing the production speed of single-thread fishing nets. Such a level of focus is extremely rare in the industry and is also reflected in every piece of equipment we manufacture.
Our single needle bed HSGE series is the workhorse for light to medium-duty net production. Perfect for agricultural shade nets, bird nets, shallow fishing nets, sports safety nets and general-purpose mesh. It runs at stable high speeds, produces clean uniform mesh, and delivers outstanding reliability for its class. If you’re producing lighter net products and want maximum value without sacrificing quality, this is your machine.
For thick, heavy-duty marine fishing nets, trawl nets, cage nets and industrial safety nets, our double needle bar warp knitting machine GE raschel series is the industry benchmark. Built with reinforced structure and heavy-duty components from top to bottom, it handles thick monofilament yarns day in and day out without breaking down. It produces strong, secure knots and consistent mesh that meets the strictest international fishing industry standards.
For customers who need custom patterned nets, logo nets or specialty mesh products, our RDJ electronic jacquard net machine series opens up entirely new product possibilities. You get all the heavy-duty performance of our standard net machines, plus the ability to run custom patterns and designs without slowing production down. It’s perfect for factories that want to expand into higher-value custom net products.
Anyone can list machine specs. What matters is what those specs actually mean for your factory. Here are the four core technical advantages that make Longlongsheng machines the top choice for professional net manufacturers, and what each one actually delivers on your production floor.
The frame is the foundation of everything. Generic machines use lightweight hollow frames to cut cost. Longlongsheng net machines use an integral reinforced heavy-duty casting frame built specifically for the constant tension of heavy monofilament net production. The frame resists deflection and vibration even at full speed and full load, 24 hours a day. What does that mean for you? It means consistent mesh size run after run, less wear on moving parts, and a machine that stays accurate for years, not months.
The cam system is the heart of any warp knitting machine, and it’s where generic machines fall apart fastest under heavy load. Longlongsheng machines use a fully enclosed oil-immersed cam transmission system. Every critical moving part runs submerged in clean lubricating oil, 24 hours a day. Compared to the open dry cam systems on generic machines, this means 3x longer component life, 60% fewer breakdowns, and months of non-stop production before you need any major maintenance. For a factory running around the clock, that’s not just a feature – that’s money in the bank.
If there’s one thing that makes or breaks fishing net quality, it’s yarn tension control. Our precision tension control system independently adjusts feeding tension for every yarn position, holding steady even at full production speed. No drifting tension, no loose knots, no uneven mesh sizes from one side of the net to the other. Every roll comes off the machine with consistent mesh size, uniform knot strength and even gram weight. That’s the consistency that keeps export buyers coming back with repeat orders.
No two net factories are exactly alike. You make specific products, for specific markets, with specific yarns and specific workshop space. That’s why every Longlongsheng net machine is fully customizable to your needs. Gauge, working width, yarn feeding configuration, take-up speed – we tune every parameter to match your exact product. We don’t sell you a standard machine and tell you to adapt your product to it. We build the machine around your product.
Specs sound great on a brochure, but what really matters is what happens when the machine is installed and running on your floor. Let’s look at a real customer case and the actual numbers they saw after upgrading to Longlongsheng equipment.
A mid-sized fishing net manufacturer in southern Vietnam had been running 6 generic Chinese net machines for 4 years. They were constantly fighting yarn breakage, high scrap rates and inconsistent mesh quality. They were losing large export orders because they couldn’t guarantee consistent quality across bulk shipments. In 2024, they replaced their 6 old machines with 5 Longlongsheng series net machines.
The results spoke for themselves within the first 3 months:
Daily net output increased by 42% with one fewer machine
Yarn breakage events dropped from 15–20 per day to just 2–3 per day
Product defect rate fell from 11% to under 2.5%
Monthly maintenance time was cut by 70%
The factory manager put it simply: “We used to spend half our day fixing machines. Now we just run them.”
Let’s translate all that into the numbers you actually care about as a factory owner:
Higher output: Faster stable speeds and fewer stops mean more meters of finished net per shift, every single day.
Less scrap: Lower defect rates mean less wasted yarn and more sellable product from every kilogram of raw material.
Lower labor: Fewer breakdowns mean less time spent fixing machines and more time spent running them.
Better orders: Consistent quality means you can bid on bigger, higher-value export contracts with confidence.
Lower long-term cost: Longer component life and less maintenance mean lower total cost of ownership over the life of the machine.
At the end of the day, that’s what a top-tier net machine delivers: not just specs, but more profit.
We get asked these questions every week by factory owners looking to upgrade. Here are straight answers, no sales fluff.
Our machines cover nearly every industrial, agricultural and fishing net category: marine fishing trawl nets, aquaculture cage nets, agricultural shade nets, sports safety nets, construction protective nets, bird nets, windbreak nets and custom specialty nets. We have configurations for light, medium and heavy-duty net products.
Absolutely. We customize machine gauge, working width, yarn tension settings and take-up systems to match your exact yarn material (PP, PE, PET monofilament), target mesh size and daily output goals. We can even run sample weaving trials for you before you order.
Yes. We offer global technical support, remote troubleshooting, and one year's worth of spare parts. The easily damaged parts equipped in the machine can be replaced immediately, eliminating the inconvenience of long-distance travel and prolonged downtime.. For bulk orders, we provide on-site installation, commissioning and operator training directly at your factory, wherever you are in the world.
Our upfront price is higher than the cheapest no-name machines, yes. But when you count lower scrap rates, fewer breakdowns, less downtime and longer machine life, our total cost of ownership is actually lower within the first 12–18 months of operation. The cheap machine only looks like a bargain until you start paying for all the problems it causes.
The knotless fishing net business is getting more competitive every year. Buyers demand better quality, tighter tolerances and faster delivery, all while raw material costs keep climbing. In that environment, your machines aren’t just equipment – they’re your competitive advantage.
Generic machines might get you started. But if you want to grow into large export orders, consistent quality and long-term profitability, you need a purpose-built machine from a manufacturer that actually understands net production. That’s exactly what Changzhou Longlongsheng delivers. We don’t try to be everything to everyone. We focus on being the best at one thing: building the most reliable, most productive knotless fishing net warp knitting machines in the industry.
