FAQ
What factors determine the quality of compression springs?
The quality depends on material selection, wire diameter precision, coil consistency, and surface treatment. At Nanpi Haokai, we control all these factors through advanced equipment and strict quality management systems to ensure each spring meets specifications.
How do you ensure consistent quality in mass production?
We implement several quality control measures including statistical process control (SPC), in-process inspections, and final product testing. Our CNC equipment maintains tight tolerances throughout production, while our quality team performs regular checks at each stage.
Can you produce springs with special requirements?
Absolutely. As a custom spring manufacturer, we specialize in producing springs to specific customer requirements. This includes unique dimensions, materials, load capacities, and even special coatings or treatments for specific environments.
What is your minimum order quantity for custom springs?
We understand that different customers have different needs. While our production is optimized for larger quantities, we can accommodate smaller orders depending on the complexity of the spring design. Please contact our sales team with your specific requirements for a quotation.
