Frequently Asked Questions
What is a 40mm base valve and what is its function in a shock absorber?
The 40mm base valve (also called foot valve) is a critical component located at the bottom of the shock absorber's inner working cylinder. With a 40mm diameter, it precisely regulates hydraulic oil flow between the reservoir and compression chamber. During compression, it controls oil passage to generate consistent damping force, directly influencing vehicle handling stability and ride comfort. The 40mm size is a common standard used in passenger car and light truck shock absorbers.
What materials are available and which is recommended?
We offer 9 material options: P/M Copper and Copper Alloys, P/M Iron and Carbon Steel, Iron and Carbon Steel, Iron-Copper and Copper Steel, Iron-Nickel and Nickel Steel Low Alloy Steel, Commix Low Alloy Steel, Sinter Hardened Steel, Diffusion Alloyed Steel, and Copper Infiltrated Iron. Our standard recommendation is FC-0208 (Fe-C-Cu), which provides 65HB hardness with density exceeding 6.5 g/cm³ — an optimal balance of strength, wear resistance, and cost for automotive shock absorber applications.
What quality certifications does XIAYI hold?
XIAYI is ISO 9001:2008 certified with extensive familiarity with TS16949 (now IATF 16949) quality management systems. Our quality control process spans incoming material inspection (IQC), in-process monitoring, and final QC. Our testing laboratory features 9 categories of precision instruments including CMM, carbon sulfur determinator, metallurgic microscope, universal material tester, and specialized durability/vibration test stands for complete product validation.
What is the minimum order quantity (MOQ)?
The standard MOQ is 1,023 pieces. Sample development time is approximately 25 days for custom designs, with delivery time of around 30 working days for new sample orders after technical details are confirmed. Our monthly supply capacity is 50,000 pieces.
What surface treatments are available and which is best for shock absorber valves?
Six surface treatments are available: sand blasting, zinc/chrome plating, rust-preventive steam treatment, painting, electrophoresis, and powder coating. For shock absorber base valves, steam treatment is the recommended standard. It creates a durable magnetite (Fe₃O₄) surface layer through controlled oxidation, which enhances surface hardness, improves wear resistance, provides corrosion protection, and has the advantage of no dimensional change — critical for precision-fit components.
Can XIAYI customize the base valve to our specifications?
Yes. XIAYI provides full OEM and ODM services. We can produce base valves according to your drawings or samples with our experienced industrial design and quality engineering team. Our aim is to optimize your design and reduce costs based on our cross-process technology expertise — covering powder metallurgy, casting, and CNC machining. We will review your requirements and provide material recommendations, process optimization suggestions, and a sample timeline.
What testing and validation does each product undergo?
We operate a comprehensive testing facility with high-low temperature chambers, vibration test stands, durability test rigs, performance simulation test benches, X-ray material testing, hardness and roughness measurement, and specialized customized testing equipment for powder metallurgy parts. Combined with 9 categories of precision measurement instruments, every production batch is validated for material chemistry, mechanical properties, dimensional accuracy, and functional performance before shipment.
What is the typical delivery time for bulk production orders?
For ongoing production orders, delivery is typically within 30 working days. For new custom designs, sample development takes approximately 25 days with subsequent production delivery of 30 working days after sample approval. Packaging uses individual plastic box protection within cartons with standard export packaging to ensure safe international transit.
What are the advantages of powder metallurgy compared to traditional machining?
Powder metallurgy offers several advantages for shock absorber components: (1) Near-net-shape production minimizes material waste and secondary machining; (2) Controlled porosity enables oil impregnation for self-lubrication; (3) Consistent density and hardness distribution throughout the component; (4) High-volume cost efficiency — our 80-150T presses produce 50,000+ pieces monthly; (5) Excellent repeatability with tight tolerances maintained across production batches; (6) Ability to create complex geometries with integrated features that traditional machining cannot achieve cost-effectively.
What payment terms do you accept and where do you export?
We accept T/T (Telegraphic Transfer) and Western Union. Pricing is negotiable based on order quantity and specifications. XIAYI exports powder metallurgy components to customers worldwide, with established supply relationships across Asia, America, and other international markets. All products are shipped in standard export packaging with individual product protection for secure delivery.
