Invested RM800,000.00 into Latest Shearography Machine for Sun Tyre
October 2007
Sun Tyre Industries Sdn. Bhd. has recently invested more than RM800,000.00 into the latest shearography machine. The machine has been developed specifically to inspect the tire carcasses that are suitable to be used for the retreading industry.
The technical basis of the systems is the phase shearography system. During the test cycle, a pressure difference (vacuum, e.g., 50 mbar) is generated in the vacuum chamber, thereby inducing deformations which are caused by the expansion of air pockets occurring in faulty areas in a tire carcass.
With the phase shearography technique - a holographic measurement method which reliably detects material deformations in the range of microns - faulty areas can be localized clearly and reproducably.
The intact tire test systems by Steinbinchler Optotechnik have successfully proven their functionality in the worldwide car truck, and aircraft industries, as well in the Formula 1 racing tire business by phase shearography the interferogram is directly recorded by a CCD-video camera.
The phase image of the original state of the tire at normal pressure is stored in the image memory of the computer. The phase images of the deformed states of the tire at decreased pressure are subtracted from the stored phase image in real¬time. Fault-typical deformations are displayed as phase difference and interference fringes on the system monitor.
The results can be stored for documentation on: hard disk of computer, CD, DVD, laser printer, customer network.
- On line evaluation, thereby enabling a direct quality verdict of the casing immediately after test procedure.
- No influence by vibration in comparison to conventional interferometric methods.
- No flim material is consumed.
- Compact, reliable set-up.
- Operation by semi-skilled staff
With this new shearography machine, Sun Tyre now able to upgrade the quality of its retread tyre by minimizing ply separation where normally cause by blister in tyre carcasses which cannot be visually inspected.
Sun Tyre today is one of the largest retread tyre manufacturer in Malaysia that has won several awards such as Golden Bull Award 2005, SMB Brand Excellence Award etc…
Sun Tyre is the first retread tyre manufacturer in Malaysia that has obtained the MS224:2005 product certification license.
Sun Tyre is also the association company of Sun Rubber Industry Sdn. Bhd. who is also one of the leading compound producer in Malaysia.
The company also export its products to more than 30 countries worldwide include Japan, Australia, New Zealand, Fiji, Indonesia, Singapore, Vietnam,. Saudi Arabia, Myanmar and United Kingdom.
