Heavy Duty Chemical Fiber Winding Tube

Our Heavy duty chemical fiber winding tube is a top-level heavy-load paper tube developed for ultra-heavy-load chemical fiber winding scenarios. For extreme production conditions of super large packages and ultra-high tension, we have created a paper tube product that can partially replace metal cores and plastic cores. With the development of chemical fiber equipment towards large-scale and high-speed, the package weight and winding tension of some special chemical fibers far exceed the bearing limit of conventional industrial paper tubes. Metal cores and plastic cores have high cost, heavy weight and inconvenient operation. Our Heavy duty chemical fiber winding tube achieves ultimate bearing capacity through multi-layer composite reinforced structure, while retaining the advantages of paper tubes such as light weight, low cost and easy processing, helping customers reduce heavy-load consumable costs.

In terms of structural design, Heavy duty chemical fiber winding tube adopts a multi-layer composite structure of "high-strength base paper + rigid reinforcement layer". The tube wall thickness and number of layers far exceed those of ordinary industrial paper tubes. Matched with high-pressure curing process, the overall rigidity and deformation resistance reach the top level of paper tube products. Its radial compressive strength and axial load-bearing capacity are 4-5 times that of ordinary industrial paper tubes, which can withstand the continuous heavy pressure of super large packages and the winding tension of ultra-high tension, and will not lose roundness, delaminate or crack during long-term use. We can also customize exclusive structure and size according to customers' heavy-load equipment parameters to ensure perfect adaptation. As a National High-tech Enterprise, we master the core composite technology of heavy-load paper tubes, and can customize Heavy duty chemical fiber winding tube with different heavy-load grades according to needs.

• Super large spinning equipment: large package heavy-duty chemical fiber spinning production lines

• Special heavy-load chemical fiber: winding of ultra-high-strength and coarse denier special chemical fibers

• Alternative to metal / plastic cores: reducing procurement cost of heavy-load winding consumables

We support in-depth customization services for heavy-load scenarios. Customers can customize basic dimensions such as inner diameter, length and wall thickness of Heavy duty chemical fiber winding tube according to equipment parameters, package weight and tension requirements, and can also customize products with different load-bearing grades by adjusting the number of reinforcement layers and material formula. For special needs of extreme heavy load, our R&D team can provide exclusive structural design solutions and cooperate with customers to complete load testing and on-machine verification. The development cycle of customized samples is about 2 weeks. Samples are provided free of charge, and only logistics fees need to be borne. Small-batch trial orders are supported to verify load-bearing performance.

For the extreme performance requirements of heavy-load paper tubes, we implement the strictest quality inspection standards. Each batch of raw materials must undergo a full strength test to ensure that raw materials meet heavy-load grade requirements. During production, the winding tension and glue application amount of each layer are precisely controlled to ensure uniform and firm interlayer bonding. At the finished product stage, static pressure failure test and long-term load test are carried out through professional pressure testing machines to verify the ultimate bearing capacity and deformation resistance. All Heavy duty chemical fiber winding tube undergoes 100% full appearance and size inspection before packaging, supports mechanical performance testing by third-party authoritative institutions, and each batch is accompanied by a complete strength test report, ensuring that products reach the designed heavy-load grade.

We have 16 years of R&D experience in special industrial paper tubes, and are one of the few enterprises in China that master heavy-load composite paper tube technology. The production base covers an area of 15,000 square meters, equipped with special production equipment for heavy-load paper tubes and mechanical performance testing centers, which can complete pressure tests up to 10 tons. The R&D team is composed of senior structure and material engineers, holding multiple core invention patents for heavy-load paper tubes. Our heavy-load paper tubes have been applied to the special production lines of many large domestic chemical fiber enterprises, with remarkable effect of replacing imported metal cores, helping customers significantly reduce consumable costs.
