Control Instrument

Supplied Raw Materials Management

Critical management of suppliers: As an important part of quality control ,we choose every component critically from the beginning.

Shanghai LIVIC Filtration System Co., Ltd.

Positive Material Identification: Check all the indefinite materials by the specialized instruments from Germany

Dimension check: According to the drawings and specifications, check all the dimensions of the components

Strict management of material storing: The warehouse is divided into Qualified Product Area, Unqualified Product Area and Uninspected Product Area. Distinguish strictly the acceptable materials from the others, and correctly handle the defective raw materials. Only the qualified materials could be transferred to the next process.

Process Quality Control

Radiographic testing： a nondestructive testing (NDT) method of inspecting materials for hidden flaws by using the ability of short wavelength electromagnetic (high energy photos) to penetrate various materials

Penetrant Testing:Find out the surface flaws as much as possible with the Capillary Phenomenon help

Filter Element Precision Detection:Inspect the micron range to make sure it is fine enough to strain out impurities.

Magnetic Flux Density Detection: The magnetic flux density must meet the demand of designing so as to achieve a perfect effect

Final Inspection

Surface Roughness Detection： Detecting the micro-height of the inner or outer surface to make sure the surface roughness is fine enough to satisfy the requirements from some special industries, such as food , pharmaceutical, and cosmetic fields

Ultrasonic Thickness Measurement: Make sure the final thickness satisfies the requirement of design minimum thickness

Hydrostatic Test: Design strength verification

Functional Test: Guarantee the function to satisfy the requests from clients

Technological Level

Precise control of opening dimension by using Wire Electrical Discharge Machining

Precise assembly operation

One side welding, no back gouging, full-penetration butt weld

Control the deformations in a sound and effective way
