Precision Capabilities
The CRM Spring Steel Flat Wire Drawing Machine is engineered for controlled dimensional reduction and stable cross-sectional geometry throughout the drawing process. Under suitable material conditions, tooling selection, lubrication, and reduction schedules, the system can achieve thickness tolerances down to approximately ±0.005 mm and width tolerances of approximately ±0.01 mm. For tighter requirements, the final sizing and tooling configuration can be optimized according to the specific spring steel grade, starting dimension, target profile, and production conditions.

Advantages of Flat Spring Steel Wire Drawing Machines
Flat spring steel wire drawing systems are designed to produce consistent flat wire with controlled dimensions and surface quality. The drawing process can be adjusted according to the steel grade, starting wire size, target profile, and required reduction, giving manufacturers greater control over the final wire properties and production results.
Consistent Dimensions: Precision dies and controlled drawing conditions help maintain stable width and thickness throughout production.
Controlled Work Hardening: A suitable reduction schedule helps control work hardening and residual stress during multi-pass drawing.
Good Surface Quality: Proper die selection and lubrication help reduce friction, surface defects, and die wear.
Flexible Process Configuration: The system can be configured for different spring steel grades, starting sizes, cross-sections, and reduction requirements. Intermediate heat treatment can be added when required.
Stable Production: Controlled drawing speed, wire tension, and take-up help maintain consistent production conditions throughout the line.
Wide Material Compatibility: The system can process carbon spring steel, alloy spring steel, and stainless spring steel according to the required finished-wire specifications.
