Conical Compression Spring Progressive Force Variable Diameter
Custom
Conical compression springs feature coils that gradually increase
from top to bottom, providing progressive force characteristics
within limited height constraints.
Compression Spring Quick Detail
Conical compression springs provide progressive force—soft
initially to absorb light shock, then increasing stiffness for
rigid stop. Solid height is extremely low, saving installation
space. Custom top/bottom OD, free length, and force curve available
with 48-hour sampling.
Compression Spring Product Description
Unlike standard cylindrical springs, conical springs achieve a
final solid height just slightly greater than a single wire
diameter as coils sequentially bottom out—dramatically saving
vertical space. The progressive force characteristic offers unique
advantages in battery contacts and shock buffers: low initial force
for easy battery insertion; high final force for reliable
electrical contact or rigid support.
Tingfeng Hardware precisely designs taper ratio and pitch
distribution to achieve specific force curves. Using CNC spring
formers for direct manufacturing eliminates tooling requirements.
We can reverse-engineer designs from target forces at different
compressed heights or manufacture directly from CAD models. Small
batches from 100 pieces with 48-hour sampling and 15 years of
spring manufacturing experience.
Frequently Asked Questions (FAQ)
Q: Can you handle complex custom designs and provide design
optimization suggestions?
A: 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.
Q: How do you ensure quality consistency and handle defect issues?
A: We implement a rigorous 4-stage QC system with 100% full
inspection. Our track record shows 99.99% qualification rate.
Q: What are your lead times and how do you handle urgent orders?
A: 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%.
Q: Will I get timely responses and professional support throughout
the project?
A: Yes. You get a 1v1 exclusive consultant with 1-hour initial
response commitment and 24-hour technical support.
Q: Can you provide material certifications and environmental
compliance reports?
A: Yes. We provide material certifications and environmental test
reports (RoHS, REACH compliant) upon request.
Q: How do you protect my designs and intellectual property?
A: We start with mutual NDA and implement strict mold ownership
protection and confidential data security measures.
Q: What are your payment terms and MOQ requirements?
A: We offer flexible payment terms (T/T, L/C at sight) and MOQ from 1
piece for prototyping.
