A Raschel warp knitting machine can typically produce about 1–3 tons of net per 24 hours under stable operating conditions. However, there is no single output figure for every machine or net product. Actual production depends on the machine width, net weight, mesh structure, yarn type, operating speed, working hours, and production efficiency.
For buyers planning a new net factory, calculate output based on the required finished product rather than machine speed alone.
Daily output can be estimated with the following formula:
Daily output (kg) = Working width (m) × Fabric speed (m/min) × Net weight (g/m²) × 60 × Operating hours × Efficiency ÷ 1,000
“Fabric speed” means the actual net take-up speed. It is not the same as the machine’s rpm because different mesh patterns require different numbers of knitting courses.
Take the Chenye HSRO-220 single needle bar Raschel machine as an example.
According to the HSRO Raschel knitting machine specifications, this model has:
· Working width: 220 inches, or approximately 5.59 meters
· Machine speed: 200–550 rpm
· Suitable net weight range: approximately 20–350 g/m²
· Applications: shade net, safety net, greenhouse net, breeding net and agricultural net
Suppose the machine produces a 100 g/m² net at an actual take-up speed of 3 meters per minute with 85% operating efficiency.
Production Schedule | Estimated Net Area | Estimated Weight |
8 hours per day | About 6,840 m² | About 684 kg |
20 hours per day | About 17,100 m² | About 1,710 kg |
24 hours per day | About 20,520 m² | About 2,052 kg |
This example is for production planning only. Confirm the final output through a test using the buyer’s yarn and net specifications.
Not necessarily. A high machine speed can increase production, but RPM alone does not determine how many kilograms of net can be produced.
For example, the Chenye RS-1 Raschel knitting machine is available in working widths from 130 to 260 inches. Depending on the width, its listed speed reaches 800–1,000 rpm. However, a lightweight mosquito net, a knotless fishing net, and a heavy safety net will have very different daily outputs even when produced on the same machine.
A dense or complicated mesh normally requires more knitting courses and may reduce the fabric take-up speed.
The main factors include:
A wider machine produces more square meters of net during each operating hour, provided that other conditions remain similar.
Net weight is normally measured in grams per square meter. Heavier net produces more kilograms from the same area, but it may require more yarn and a lower production speed.
Large, simple mesh structures are generally faster to produce than small, dense or complicated patterns.
HDPE flat yarn, PP yarn, monofilament, multifilament, and other materials require different yarn tensions and machine settings.
Yarn changes, machine cleaning, maintenance, pattern adjustments, and unexpected stops reduce effective production time. For factory planning, using an efficiency rate of 80–90% is usually more realistic than assuming uninterrupted production.
Before selecting a Raschel warp knitting machine, provide the manufacturer with:
· Net application
· Net width and mesh size
· Net weight in g/m²
· Yarn material and yarn specification
· Required daily output
· Planned operating hours
Chenye can use this information to recommend a suitable machine width and configuration. If possible, sending a finished net sample or detailed product photos will make the production estimate more accurate.
For many common agricultural, construction, and packaging nets, a practical planning estimate is approximately 1–3 tons per machine per 24 hours. Nevertheless, the correct figure depends on the exact net and operating conditions.
