Welcome to Anping County Boli Hardware Wiremesh Products Factory – your trusted manufacturer of high-performance filtration solutions since 1998. Our Customized Sintered Powder Metal Filter is engineered to deliver exceptional durability and precision in demanding industrial environments. Available in 304 or 316L stainless steel with a filtration range of 5–100 micron, this product is fully customizable to meet your specific requirements. Backed by over two decades of manufacturing expertise and an annual export value of US$5–10 million, we provide comprehensive technical support to ensure optimal performance in your application.
Our sintered powder metal filters are produced through a controlled powder metallurgy process, where metal powders are compressed and sintered at high temperatures to form a rigid, porous structure. This manufacturing method creates a uniform pore distribution and high mechanical strength, making these filters ideal for fine filtration, backwashing, and high-temperature or corrosive environments. Below are the key features and specifications:
Key Features & Technical Specifications
- Material Options: 304 stainless steel (general corrosion resistance) or 316L stainless steel (superior resistance to chlorides and acids). Both are food-grade and suitable for pharmaceutical, chemical, and water treatment industries.
- Filtration Precision: Available from 5 micron to 100 micron, with a narrow pore size distribution for consistent filtration efficiency.
- Customizable Shapes & Sizes: We can produce tubes, discs, plates, cylinders, or custom geometries according to your drawings or samples. Diameter, length, thickness, and end caps are all adjustable.
- High Mechanical Strength: The sintered structure provides excellent pressure resistance and can withstand backwashing and cleaning cycles without deformation.
- High Temperature & Corrosion Resistance: 304/316L grades allow operation up to 600°C (in non-oxidizing atmospheres) and resist a wide range of chemicals.
- Easy Cleaning & Regeneration: The porous metal filter can be cleaned by backwashing, ultrasonic cleaning, or chemical washing, extending service life.
- ISO Standard Compliant: Our manufacturing process follows international quality standards to ensure consistent product performance.

Frequently Asked Questions
-
Q: What is the difference between 304 and 316L sintered filters?
A: 304 offers good general corrosion resistance and is cost-effective. 316L has added molybdenum, providing superior resistance to chlorides, acids, and pitting. For harsh chemical or marine environments, 316L is recommended. -
Q: Can you produce filters with a specific micron rating, e.g., 15 micron?
A: Yes, we can customize the filtration rating within the 5–100 micron range. The actual pore size is controlled by powder particle size and sintering parameters. Please specify your requirement. -
Q: What is the maximum pressure drop these filters can handle?
A: The pressure drop depends on the shape, thickness, and porosity. Typically, our filters can withstand differential pressures up to 10–20 bar. For higher pressure applications, we can reinforce the structure. -
Q: How do I clean a sintered metal filter?
A: Common methods include backwashing with clean fluid, ultrasonic cleaning, or chemical cleaning with mild acids/solvents. Avoid using abrasive tools. Our filters are designed for repeated cleaning. -
Q: Do you provide samples for testing?
A: Yes, samples are available for evaluation. Please contact us with your dimensions and material preference. We can produce small quantities for trial purposes. -
Q: What is the typical lead time for custom orders?
A: For standard sizes, lead time is 7–15 days. For complex custom shapes, it may be 20–30 days depending on quantity. We can expedite for urgent orders. -
Q: Are these filters suitable for food contact applications?
A: Yes, 304 and 316L stainless steel are food-grade materials. Our filters are manufactured under clean conditions and can be used in food & beverage filtration. -
Q: What quality certifications do you have?
A: Our products comply with ISO standards. We can provide a material test report (MTR) and dimensional inspection certificate upon request. Third-party testing is also welcome.
