ADVANTAGES OF NICKEL COATING
No Additional Coating Prior To Coiling
Nickel plated wire has excellent lubrication performance to minimize friction during the coiling process. No additional lubrication is required even for high speed coiling or the production of intricate springs with D/d of 3.
High Productivity And Low Cost
The consistent and uniform lubrication helps provide stable spring dimensions and less load variations during coiling. Nickel coating allows you to produce springs of tight tolerance in an economical manner with much higher yields and greater throughput on your equipment.
No Preparative Treatment Prior To Heat Treatment
The need for pretreatments, such as pickling and degreasing, is eliminated prior to heat treatment. During heat treatment, expect no major color change even under the recommended temperatures of 700F to 800F. Nickel coating allows you to save time, cost and headaches by reducing the number of manufacturing steps required.
Durable And Consistent Finish
The characteristics of nickel coating allow the springs to retain its same bright, consistent finish even after heat treatment. Nickel coated stainless springs are cosmetically and functionally interchangeable with non-coated stainless steel springs.
