BTJSLNDT Series Tire Speckle and Nondestructive Laser Testsing System

Brief Introduction: BTJSLNDT series tire speckle and nondestructive laser testsing system is a new generation tire nondestructive test instrument that was researched and developped by China engineers. It is applicable to the tire quality detection in design, research and production enterprises, especially system becoming the most effective means to control the quality of aviation tires, steel radial car tires, and OTR tires. It also applies to retread tires, being an ideal device for test classification prior to tires retreading and quality test after retreading. This system is mainly used for detection of such defects as bubble and layers separation to prevent detective tires leave the factory, thus ensuring the safety of plane flight and automobile driving.

System Characteristics:

• Usually according to the circumstance 360 angles, the surface of the tire can be divided into 6-12 sectors. Tires are delivered to a vacuum case horizontally before test. A measure probe stretched into the tire case and automatic placed for testing. This system has the high adaptability, it can measure any tire of different external diameter and sectional height. It also can take pictures outside.
• The system can detect the tire inner defects and cause tire to attain high security standard, especially in the retreading industry, because any unqualified tire will be vanished in the pretreatment, so to avoid wasting manpower and resource and economy lost. After tire retreading, this equipment can detect the quality of the retreading tire whether up to the control equipment.

Applications: Apply to the aviation tire, car tire, trunk tire, OTR tire and retreading tire, not only for radials structure, but also for bias, besides the system also applies to the measurement of compound material articles.

• BTJSLNDT 800 suitable to mini aviation tire and car tire
• BTJSLNDT 1200 suitable to car tire, truck tire and OTR tire
• BTJSLNDT 1600 suitable to truck tire, OTR tire and aviation tire
