Product Name: Shock Absorber Base Valve / Foot Valve, manufactured
from Raw Materials MPIF FC-0208 iron-based powder metallurgy. This
precision valve is produced through advanced powder compaction
molding technology, where metal powder is compacted in a die under
high pressures with vertically oriented tooling. The compacted
shape is then ejected from the die cavity, requiring minimal
additional work for its intended use, making for highly
cost-efficient manufacturing.
Full line products for shock absorber systems are available,
including powder metallurgy piston, rod guide, foot valve, PTFE
band for piston, and DU bearing for rod guide. PPAP Level III
documentation is submitted accordingly.
Powder Compaction Molding TechnologyPowder compaction is the process of compacting metal powder in a
die through the application of high pressures. Tools are held in
vertical orientation with the punch tool forming the bottom of the
cavity. The powder is then compacted into shape and ejected from
the die cavity. This process yields parts requiring very little
additional work, making for extremely cost-efficient manufacturing.

Frequently Asked Questions (FAQ)Q1: What is MPIF FC-0208 material and how does it compare to
FC-0205?
MPIF FC-0208 is an iron-copper-carbon powder metallurgy material
with higher carbon content compared to FC-0205, providing enhanced
hardness and wear resistance. With surface hardness reaching
HRB65-95 and density of 6.8 g/cm3, this material is ideal for shock
base valves that require superior surface durability and stable
performance under millions of compression cycles.
Q2: What is powder compaction molding and why is it cost-effective?
Powder compaction molding compresses metal powder in a precision
die under high pressure using vertically oriented tooling. The
process produces near-net-shape parts with excellent dimensional
accuracy, requiring minimal secondary machining. This translates to
significant cost savings through reduced material waste, shorter
production cycles, and lower machining requirements compared to
traditional manufacturing methods.
Q3: What does your PPM 60 quality target mean for customers?
PPM (Parts Per Million) 60 means our quality target is no more than
60 defective parts per million produced, equivalent to a 99.994%
quality rate. This automotive-grade quality standard, combined with
our IATF16949:2016 certification and CPK measurement reporting,
ensures reliable, consistent product performance for your shock
absorber applications.
Q4: What documentation do you provide with each shipment?
We provide comprehensive quality documentation including
measurement reports with CPK values, corresponding bubble drawings,
material certificates, and hardening/surface treatment reports
where applicable. All parts are inspected before delivery to ensure
they are in good condition. PPAP Level III documentation is also
available for automotive customers.
Q5: What is your MOQ and sample lead time?
Our standard MOQ is 1,042 pieces per order with a monthly supply
capacity of 50,000 pieces. New sample development takes
approximately 25-30 working days. We accept T/T, , and L/C payment
terms. Products are individually packed in plastic boxes, then in
cartons with standard export packaging.
Q6: What materials can you work with for powder metallurgy parts?
We have extensive experience with three major categories: copper
alloys, iron alloys (including FC-0205 and FC-0208), and hard metal
alloys. Our full product line covers shock absorber components
including pistons, rod guides, foot valves, PTFE bands, and DU
bearings. We also produce gears and custom sintered parts for
automotive, motorcycle, pump, and industrial applications.
Q7: Can you support synchronized development with our engineering
team?
Yes, we offer synchronized development design services to
collaborate with your engineering team from concept through
production. Supported by our comprehensive testing laboratory (CMM,
metallurgic microscope, universal material tester, profilometer,
and more), we provide technical consultation and design
optimization to meet your exact specifications. Our 7-day 24-hour
online service ensures continuous support across time zones.
