FAQ
What types of spring components can you manufacture?
We specialize in three main categories: precision stamped spring components, CNC machined spring parts, and custom non-standard spring solutions. Our capabilities include compression springs, torsion springs, leaf springs, and various specialized spring forms for industrial applications.
What materials do you use for spring component production?
Our standard materials include cold-rolled steel, stainless steel (304, 316), brass, phosphor copper, aluminum, and various alloys. We can also source specialized materials based on customer requirements for specific environmental or performance needs.
How do you ensure the quality of your spring components?
Quality control begins with material inspection and continues through every production stage. We use advanced measuring equipment and statistical process control to maintain tolerances. Final inspection includes dimensional verification, functional testing, and surface inspection before packaging.
What is your minimum order quantity for custom spring components?
We accommodate both small and large production runs. Our minimum order quantity typically starts at 1,000 pieces for custom designs, but we can discuss lower quantities for prototype or initial production needs. For standard components, we maintain inventory for immediate shipment.
How long does it take to produce custom spring components?
Production lead times depend on component complexity and order quantity. Simple designs can be produced in 2-3 weeks after final approval, while more complex components may require 4-6 weeks. We provide detailed timelines during the quotation process.
