Hello! I am Xiong Yejun, general manager of Dongguan STL Metal Products Co.,Ltd. First of all, I would like to extend my sincere gratitude to China Fastener Directory for offering me a great opportunity to introduce my company periodically. In this issue, I will give my presentation of the testing equipment performance  at STL.

The DIN65151 transverse vibration testing equipment, currently the world’s most advanced vibration anti-loosening testing equipment, is effective for inspecting the anti-loosening characters of fasteners in the vibration condition. The machine simulates the continuous high frequency of strong vibration environment by applying the maximum load of reciprocating vibration impact on locking washers, so as to ensure that the locking washers meet the anti-loosening performance during installation.

As the saying goes, “A thing is valued in proportion to its rarity”. The DIN65151 transverse vibration testing equipment has the state-of-the-art technology and is sold by only few companies. Therefore, its price will be more expensive accordingly. From the cost perspective, most of the companies cannot afford to buy it even though they are in want of it. STL is the first fastener manufacturer in China equipped with this transverse vibration testing equipment.



A qualified locking washer must be strictly implemented production process control and quality process control. From this aspect, the testing on product function is particularly important. If our products can merely meet the appearance requirement but go far from the function, the risks are very likely to occur. As an influential locking washer brand manufacturer in the industry, we have obtained various quality control certificates. We have been strictly following the quality process by applying various quality control methods (including testing equipment, testing standards, testing procedures). Our business goal is to pursue the quality concept of zero defects, making the world believe in made-in-China products.



In terms of the goal of STL factory, we are committed to offering locking washer applications and solutions, and ensuring the security and reliability of locking washers with brand name “SZJYD-LOCK”. We have been working on locking washers for ten year and we will always provide our users with safe and reliabe locking washers.
