Transmission Spring Solution: Challenge & Response

Challenge	CATALOG’s Response	Outcome
Small coil ratio makes winding difficult, resulting in poor verticality and high force-value precision requirements. This affects both assembly and functional performance.	• Apply advanced winding techniques to overcome processing challenges. • Implement a custom grinding-disc process to ensure perpendicularity. • Use pre-setting treatment to control force-value accuracy.	High-quality springs with precise force output, guaranteed verticality, and seamless installation and validation.
