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.
