Raw Material Excellence

Our journey to excellence begins at the source with our raw material selection. We procure only the highest-quality stainless steel from certified suppliers, chosen for its resilience and purity.

Each batch undergoes a two-fold inspection:

1. Chemical Composition Analysis of Raw Materials:

The primary tool we utilize is a spectrometer, capable of rapidly and accurately analyzing the chemical composition of metal alloys.


  • Sample Preparation: Initially, representative samples are extracted from each batch of raw materials.
  • Surface Preparation: Ensuring the sample surfaces are clean, and free of oil, and oxides, to prevent interference with the test results.
  • Spectroscopic Testing: Samples are excited within the spectrometer, prompting their atoms to emit light at distinct wavelengths.
  • Data Analysis: The spectrometer captures this light, enabling us to determine the concentration of each element within the sample.
  • Result Evaluation: Test results are compared with international standards or customer specifications to ensure that the content of each element is within the prescribed range.

2. Mechanical Property Tests of Raw Materials:

  • Hardness Test
  • Tensile Test

Meticulous Manufacturing Process

During the manufacturing process, we employ advanced process monitoring systems to continuously monitor production parameters in real time. Weld quality is subjected to non-destructive testing to ensure the integrity of the welds.

Precision measuring tools and equipment are utilized to ensure the accuracy of product dimensions.

Rigorous Finished Product Testing

Each filter housing must pass a series of rigorous tests before it leaves our facility.

A critical component of this testing is the pressure test, an essential step to validate the seal integrity and structural soundness of our stainless steel filters.

Pressure Test Procedures:

  • Test Preparation: Install the filter on a dedicated pressure testing bench and ensure all connections are sealed.
  • Pressurization: Gradually increase the pressure inside the filter by injecting air or water through a pressure pump.
  • Pressure Maintenance: Once the predetermined test pressure is reached, maintain that pressure for a specified period, usually ranging from a few minutes to several hours, depending on the product type and customer requirements.
  • Observation and Recording: During the pressure maintenance phase, observe the filter for any leaks or other anomalies. Meanwhile, monitoring equipment will record any pressure drops to assess the product’s sealing performance.
  • Pressure Release: After the test, slowly release the pressure to avoid damaging the filter.
  • Result Assessment: If the filter exhibits no leaks and maintains stable pressure throughout the test, it is deemed to have passed the pressure test.

Careful Packaging and Transportation

Our commitment to quality extends to the careful packaging and transportation of our products. Each filter housing is secured in custom packaging designed to protect it during transit.

We collaborate exclusively with reliable logistics partners to ensure that each filter reaches its destination in pristine condition.

Customer Feedback and Continuous Improvement

We actively gather customer feedback to continuously refine and enhance our products.

Additionally, we conduct regular internal audits and quality reviews to ensure our production processes consistently meet the highest standards, demonstrating our commitment to excellence and customer satisfaction.
