Sailun Establishes Retread Demonstration Centre

Sailun Co., Ltd. created its experimental demonstration centre for tyre recycling in 2007. The centre was established and developed as a professional tyre recycling business, which focussing on tyre retreading, retread materials manufacturing, rubber powder production and application, R&D and the production of a range of retreading equipment, providing clients with a complete solution to tyre retreading issues, and also assisting clients with professional services on tyre management for their vehicle fleets.

At present, the Centre has established a precured retread production line for truck tyres and Sailun's Retread Demonstration Centre is a state of the art showcase for its products passenger car tyres, which has reached an advanced international level and is capable of retreading 150,000 tyres per year. All levels of inspection equipment are used before retreading, including a nail hole inspection machine, loose spot laser checking machine and a tyre pressure checking machine used to ensure the quality of the retreaded tyres.

In 2008, the centre was recognised as the demonstration centre for tyre retreading in Qingdao, even for the whole of China. Additionally, the centre shouldered the responsibility for several important technical and industrial projects issued by the National Development and Reform Committee, known as the Rubber and Tyre Cycling Utilization Project.

The centre possesses 38 items of patented equipment. The centre is also participating in or taking charge of national standards and industrial standards for a total of 6 items, such as methods for dealing with waste and worn tyres, setting up qualifications for tyre retreading enterprises, and technical standards for tyre retreading.

In co-operation with MESNAC, Sailun has been researching and designing an entire set of equipment used for tyre retreading and inspection to meet the requirements of medium and high-end clients both at home and abroad. The techniques used meet international standards. The inhouse developed equipment includes a pin hole inspecting machine, a holographic laser inspection machine and a highpressure tyre inspection machine. The centre utilises advanced precured retreading techniques including double envelope curing and the use of precured tread strips. Moreover, the centre strictly controls the process in terms of tyre carcass examination standards with a flow chart for retreading, with operation instructions (process procedure) in every position, checking standards for finished products, repair standards and so on. Inspected by the China National Tire Quality Supervision and Inspection Centre, all retreaded tyres from the centre are up to the highest standard.

Technical Features:

The Centre says it offers advanced precured tyre retreading techniques and reached an international standard in the 1990s. The equipment used includes the latest developments in retreading throughout its processes. The equipment is specially designed for local users and provides them with integral solutions.

The tread rubber produced by the facility is available in a dualcompound formulation, which is claimed to be superior to overseas products using single formulations. The anti-abrasion performance can reach beyond the level of new tyres with as much as 15 per cent higher mileage. The heat dissipation capability is also claimed to be superior to overseas products.
