FAQ
What is the minimum order quantity for custom electronic springs?
We accommodate both small and large production runs. Our minimum order quantity typically starts at 1,000 pieces for custom electronic springs, but we can discuss lower quantities for prototyping or initial production runs depending on the complexity of the design.
How do you ensure the quality consistency of electronic springs in mass production?
Quality consistency is maintained through our comprehensive ISO9001:2015 certified quality management system. We implement statistical process control (SPC) methods, conduct regular in-process inspections, and perform final inspections on 100% of produced electronic springs to ensure consistent quality throughout mass production.
What lead time can I expect for electronic spring production?
Production lead times vary based on order quantity and complexity. For standard electronic springs from our inventory, we can typically ship within 5-7 business days. For custom orders, the lead time is usually 3-4 weeks from sample approval to mass production completion, with expedited options available for urgent requirements.
Can you provide material certification for electronic springs?
Yes, we can provide material certification documents including mill test reports (MTRs) that verify the chemical composition and mechanical properties of the materials used in your electronic springs. These certificates comply with international standards such as ASTM, EN, or JIS depending on your requirements.
