Custom Non-Standard Compression Springs
Specializing in small batch manufacturing and fast sampling of precision compression springs for R&D and trial production applications.
Compression Spring Overview
During product R&D or small-batch trial production, standard springs often fail to meet specific requirements. With 15 years of precision spring manufacturing experience, we specialize in non-standard, small-batch, urgent-delivery compression spring customization. Our engineering team provides DFM feedback within 24 hours and delivers qualified samples within 48 hours, serving as your engineering solution provider for challenging "can't buy, can't wait" scenarios.
Engineering-Driven Custom Solutions
In precision equipment and mechanism design, standard springs frequently compromise performance or delay market entry. Our flexible production system within our 5,000㎡ factory enables true non-standard customization. Simply provide drawings or load requirements, and our engineering team conducts immediate design and process reviews, offering optimization suggestions for improved performance and manufacturability.

Frequently Asked Questions
Can you handle complex custom designs and provide design optimization suggestions?
Absolutely. This is our core expertise. We provide free DFM analysis within 3-5 days, often helping clients achieve 15-30% cost reduction through design for manufacturability.
How do you ensure quality consistency and handle defect issues?
We implement a rigorous 4-stage QC system with 100% full inspection. Our track record shows 99.99% qualification rate.
What are your lead times and how do you handle urgent orders?
Standard lead times: 3-7 days for prototypes, 7-15 days for mass production. We offer VIP prioritization cutting lead times by up to 30%.
Will I get timely responses and professional support throughout the project?
Yes. You get a dedicated consultant with 1-hour initial response commitment and 24-hour technical support.
Can you provide material certifications and environmental compliance reports?
Yes. We provide material certifications and environmental test reports (RoHS, REACH compliant) upon request.
How do you protect my designs and intellectual property?
We start with mutual NDA and implement strict mold ownership protection and confidential data security measures.
What are your payment terms and MOQ requirements?
We offer flexible payment terms (T/T, L/C at sight) and MOQ from 1 piece for prototyping.
