FAQ about Longlongsheng Warp-Knitting Machines for Shade Nets

This article discusses the operating speed and production capacity of Longlongsheng’s warp-knitting machines for shade nets, as well as their ability to adjust web width, suitability for different raw materials, knitting density and mesh precision, equipment stability and failure rates, energy consumption and operating costs, and after-sales and technical support.

Machine Operating Speed and Production Capacity

Hello, our Longlongsheng equipment performs exceptionally well in terms of speed and production capacity. For example, our proven GE2819 double-bed shade net machine can reach a maximum speed of 600 rpm, effectively meeting the demands of high-efficiency production. Meanwhile, models such as our SGE2319TL maintain a stable weaving speed of 200–450 rpm, ensuring consistent output during prolonged high-speed operation.

Web Width Adjustment Capabilities

We fully understand our customers’ diverse requirements regarding web width and therefore offer highly flexible options. Our widest model, the SGE2319TL single-bed warp knitting machine, boasts an impressive working width of up to 532 inches (approximately 13.5 metres). The working widths of our standard models also cover a wide range of specifications, from 42 inches (approx. 1.1 metres) to 434 inches (approx. 11 metres), allowing you to customise flexibly according to your own production needs.

Raw Material Compatibility

You can rest assured regarding raw material compatibility. Our warp knitting machines are perfectly suited to monofilaments spun from HDPE (high-density polyethylene), PP (polypropylene), as well as various synthetic fibres such as nylon, polyester and viscose. Whether flat or round yarns, our warp feeding system ensures stable and precise operation, thereby guaranteeing consistent quality in the finished shade net products.

Weaving Density and Mesh Precision

We place great emphasis on the final product quality, which is why we have devoted significant effort to weaving precision. Our equipment can precisely control mesh size and fabric density by adjusting the density range (for example, the GE2819 model has an adjustable range of 2.0–14.5 turns per centimetre), meeting various shading requirements. This is underpinned by our commitment to quality from the very outset; we have invested heavily in high-precision machine tools—including vertical and horizontal machining centres and gantry milling machines—to manufacture core components, ensuring stable equipment operation and a finished mesh surface that is neat and uniform in mesh size.

Equipment Stability and Failure Rate

The stability of our equipment is the cornerstone of our business. Taking the GE2819 shade net machine as an example, it employs a robust double-needle-bed Raschel structure, combined with four sets of three-roller active warp feeders and an oil-immersed eccentric connecting rod mechanism (widely used in the HSGE, SGE2318 and other series), ensuring the machine remains smooth and reliable even during high-intensity production. With nearly three decades of warp knitting expertise in the shade net machine sector, our products enjoy a high market share both domestically and internationally, which serves as further testament to their low failure rate and exceptional reliability.

Energy Consumption and Operating Costs

We fully understand the importance of energy saving and cost reduction to you. Taking the GE2819 shade net machine as an example, its main motor power is 5.5 kW, whilst the SGE2318 model also has a main motor power of 5.5 kW. Of course, specific energy consumption depends on the configuration, but this demonstrates that we have prioritised energy efficiency from the very outset of the design, striving to enable you to create greater value at a lower electricity cost.

After-sales and Technical Support

We provide comprehensive, end-to-end after-sales service to ensure you have complete peace of mind. Our support covers everything from installation and commissioning, through to operational training, fault diagnosis and the supply of spare parts. As a high-tech enterprise with nearly 30 years of industry experience, we remain committed to our service philosophy of ‘customer first, integrity above all’. Whatever issues you may encounter, our team will respond promptly to provide you with professional and efficient solutions.
