KOSUN technologies manufactures high performance shale shaker screens designed to handle large liquid flow rate capacity, plugging & blinding resistance, durable & long lasting construction at an economical price. Mechanically, the goal of a powder-coated pretensioned screen is to laminate multiple layers of wire mesh to a perforated steel plate and welded steel frame. As such, the quality of a powder-coated pretensioned screen is related to the bonding strength of the powder coat and the chemical and thermal resistance of the powder coat to environmental attack. KOSUN's shaker screens meet those standards and provides our customers with a high quality dependable product capable of achieving a cut from 925 to 98 microns (D100 API rating).

Process and Quality Control When curing temperatures and raw material preparation are not carefully controlled, failures become highly likely with respect to screen to frame fusing, powder coat bonding, and screen surface strength. Ultimately, screens prematurely delaminate or tear.
As a result of these efforts, KOSUN has developed a sophisticated quality assurance program. This program includes sand-blasted frames to ensure a high-grade anchor profile capable of supporting a quality coating bond, thoroughly cleaned perforated plates to ensure that no remaining oils or contaminants remain, and carefully examined stainless steel wire mesh to ensure that no defects are present.
To ensure that each KOSUN shale shaker screen meets minimum quality standards, the temperatures, melt times, and hold pressures are carefully monitored with calibrated instrumentation. From each batch, screens are selected for destructive quality control testing. Screens are submitted to a battery of quality control inspections, including coating consistency, coating adhesion properties, and mechanical strength.
Verification and Field Testing KOSUN has conducted a host of chemical immersion tests, including; diesel, alpha-olefin, calcium chloride, caustic soda, and kerosene. In all cases, KOSUN’s new polyester powder-coated screens demonstrated superior environmental exposure resistance, when compared to competitor screens.
Upon successful lab testing, KOSUN submitted hundreds of screens to actual field trials. It was these field trials that confirmed that KOSUN had achieved a significantly higher level of quality and value. http://www.kosunservices.com/solids_control_equipment/decanter_centrifuge.html
