Buy & Import Carbon Fiber Tubes from Nantong Toptek Composite Materials Co., Ltd. - Wholesale Supply

Nantong Toptek Composite Materials Co., Ltd. supplies carbon fiber tubes manufactured in Jiangsu, China. The tubes contain approximately 75 % carbon fibre by weight and are produced with an outer‑diameter tolerance of ±3 % and an ellipticity tolerance of ±2 %, ensuring dimensional accuracy for precision components. Each tube is 60 cm long, and the linearity deviation is limited to 15 % across the length, which is suitable for applications that demand straightness. The composite matrix uses a standard epoxy system that provides good heat resistance and electrical conductivity.

For carbon‑tube products of this size, a typical wall thickness ranges from 0.8 mm to 2 mm, and the resin system commonly meets a glass transition temperature of at least 180 °C. Standard industry practice calls for a surface finish that is smooth to the touch, with a typical outer‑diameter tolerance of ±0.3 mm after curing. The tubes are usually packed in cardboard cartons, each containing 10 pieces, with additional protective foam inserts to prevent impact during transit. These typical specifications align with the requirements of model‑aircraft manufacturers and medical device makers that need high stiffness and low mass.

Potential buyers include manufacturers of lightweight structural components for model aircraft, sporting equipment, and certain medical devices where biocompatibility and X‑ray transparency are valued. The supplier can accommodate order quantities that match production needs and offers trade on FOB or CIF terms, with payment accepted via L/C or T/T. Prospective customers should request the specific test reports for tensile strength, dimensional inspection, and biocompatibility to verify that the tubes meet their regulatory standards.

Frequently Asked Questions About Carbon Fiber Tubes from Nantong Toptek Composite Materials Co., Ltd.
The tubes contain 75 % carbon fibre by weight, which provides high specific strength and stiffness; buyers should request a fibre‑volume‑fraction test report to confirm this figure.

Sourcing Carbon Fiber Tubes from Nantong Toptek Composite Materials Co., Ltd. - China Import Guide

When evaluating Nantong Toptek, confirm the factory address in Rugao and ask for recent on‑site photographs or a third‑party audit to verify production capability. Request the material safety data sheet for the epoxy resin and the fibre‑volume‑fraction analysis to ensure the 75 % carbon content meets your design criteria.

Agree on the Incoterm - FOB Rugao or CIF to your destination port - and obtain a detailed freight quote based on the carton dimensions and weight. Discuss the expected lead time, which will depend on the order volume and any required custom machining, and request a production schedule with milestones. Payment can be arranged via irrevocable L/C at sight or T/T after receipt of the inspection certificate, as mutually agreed.

Plan for a pre‑shipment inspection conducted by an independent agency, focusing on dimensional tolerances, wall thickness, and resin cure quality. Insist on receiving a full inspection report together with the tensile strength and linearity test certificates. Retain all documentation, including the packing list and certificates, to streamline customs clearance and future quality audits.
