South KoreaSAMSOL Group was established in 1986 and is located in Gyeonggi-do, South Korea.SAMSOL springs feature unique production processes, being the world's first mold springs with all specifications and models side-marked. This greatly facilitates users in immediately identifying the spring's specifications and models, as well as simplifies daily management. SAMSOL's end-face grinding adopts a progressive grinding method, unlike the forced grinding used for other springs, which significantly ensures the spring's lifespan and maintains its perpendicularity below 1.2°, far exceeding industry standards.

SAMSOL springs possess a unique manufacturing process technology patent—wire arrangement engineering. From the user's perspective, it focuses on the stability of spring force values and the research on fatigue relief effects, providing customers with high-quality products. To enhance the mechanical strength and fatigue resistance of the springs, effectively extending their service life, all SAMSOL springs undergo two shot peening treatments, including coarse and fine shot peening, ensuring more thorough removal of residual stress on the spring surface. SAMSOL's coating is uniform inside and out, making it less prone to rust and breakage. SAMSOL mold springs are manufactured according to the Japanese JIS standard, with a lifespan of 1 million cycles for P1 mold strokes, 500,000 cycles for P2, and 300,000 cycles for P3. We compare prices for the same quality and compare services for the same price.
