[INQ. NO. 2207M10] CTR Co., Ltd. is an automotive parts manufacturer that under the slogan of “Central to your safety mobility,” aiming to become a leading provider of safe products and services related to all transportation.
The company started as Shilla Machinery Store in 1952, selling auto parts in a small store, and grew into a global business. Its product line includes ball joints, which make up more than 10% of the global market, as well as suspension, powertrain, and steering part items.
CTR operates an OE business that supplies products to car makers and AM (Aftermarket) businesses. It is also distinguishing itself in the future eco-mobility industry, with more than 25% of the world’s EVs using CTR’s lightweight parts.
Featuring the world’s first utilization of the insert injection method
CTR’s ball joint is distinguished by being the world’s first to utilize the insert injection method, which grants the aspherical ball stud the freedom to rotate and move. By implementing this injection method, CTR has successfully stabilized performance by eliminating errors in processing dimensions or assembly loads.
Additionally, CTR has incorporated high-strength and high-performance materials, such as high-heat-resistant plastics that surpass previous specifications by 2.4 times, to enhance durability by minimizing torque magnification, increasing pull-out strength, and improving overall durability.
The upper caulking technology developed to improve corrosion problems
Furthermore, CTR developed upper caulking technology to improve corrosion problems caused by exposure of lower machining parts (unpainted parts) that is a problem with the lower caulking type. The upper caulking type whose machining part (unpainted area) is formed toward the upper direction and is not exposed outward after the final boot is assembled, which is beneficial to suppressing corrosion.
CTR’s upper caulking technology was first applied to domestic automobiles and completely eliminated issues such as bad caulking and excessive gaps. Consequently, this technology has proved to be superior, and furthermore registered a patent — and now it is being widely applied to domestic and overseas automobiles.
