Q1: What is MPIF FC-0205 material and why is it used for shock base valves?
MPIF FC-0205 (equivalent to DIN 30910-4 Sint C10) is an iron-copper-carbon powder metallurgy material with Fe as the base, 1.5-3.9% copper, and 0.3-0.6% carbon. This composition provides an optimal balance of strength, wear resistance, and dimensional stability, essential properties for shock absorber base valves that must endure millions of compression cycles under variable loads.
Q2: What does steam oxidation treatment do for powder metallurgy parts?
Steam oxidation exposes sintered parts to high-temperature steam for 2 hours, forming a controlled Fe3O4 (magnetite) layer of 0.004-0.005mm thickness with 2-4% oxidation degree. This treatment seals surface porosity, dramatically improves corrosion resistance, enhances surface hardness, and increases wear resistance, all while maintaining precise dimensional tolerances critical for shock absorber valve performance.
Q3: Are you able to provide PPAP documentation for automotive customers?
Yes, we submit PPAP Level III documentation as standard for automotive customers. Our quality management system is certified to IATF16949:2016, and we apply core automotive quality tools including APQP, FMEA, MSA, PPAP, and SPC throughout our production process to ensure full traceability and compliance.
Q4: What is your minimum order quantity and production capacity?
Our standard MOQ is 1,000 pieces per order. We maintain a production capacity of 100,000 sets per month, supported by multiple hydraulic presses (up to 800T capacity) and six sintering furnaces. Sample orders can be delivered within 10 working days, with bulk production lead time of approximately 30 days.
Q5: What other shock absorber components do you manufacture?
We offer a complete product line for shock absorber systems including powder metallurgy pistons, rod guides, foot valves (base valves), PTFE bands for pistons, and DU bearings for rod guides. Our product range also covers gears and other sintered parts based on iron-based or stainless powder materials for various automotive, motorcycle, and industrial applications.
Q6: How do you ensure dimensional accuracy and surface quality?
We maintain tolerances per customer drawings or ISO 2768-m / H14, h14, IT14/2 standards. Our inspection equipment includes CMM (Coordinate Measuring Machine), Three-D measuring machines, optical projectors, pneumatic measuring instruments, electrical profile meters, and precision calipers/height gages. Every part undergoes 100% inspection before shipment, with appearance checked for freedom from crumbling, cracks, exfoliation, voids, and metal pitting.
Q7: Can you produce custom specifications based on our design requirements?
Absolutely. With over 3,000 existing molds and comprehensive in-house tooling capabilities (EDM, wire cutting, CNC machining), we can develop custom powder metallurgy components to your exact specifications. Our independent RandD team works closely with customers from prototyping through PPAP submission to mass production, ensuring your design intent is fully realized.
