R&D Organization
EF Technology operates a dedicated R&D department recognized by the Ministry of Science and ICT (registered with the Korea Industrial Technology Association, KOITA, No. 2024156773, October 2024). The department researches anodizing process optimization, component durability evaluation and reduction of the environmental impact of process by-products in the fields of surface treatment, electrochemistry, mechanical engineering and environmental engineering.
The department is equipped with a surface roughness tester, coating thickness gauge, Vickers hardness tester, salt spray tester and cross-section specimen preparation equipment (cutter, mounting press, polisher). Research projects are funded by the company's own budget, and the results have led to four registered patents and on-site process improvements.
Core Research Areas
01Atmospheric-Pressure Plasma PretreatmentA non-contact pretreatment technology that cleans and activates metal surfaces with atmospheric-pressure plasma, without chemicals.OutcomesThree registered patents (process, transfer and hanging structure); concept design of the generation module completed
StatusPreparing for prototype verification
02Anodizing of Die-Casting AlloysA process technology that forms a uniform soft coating on high-Si die-casting alloys.OutcomesOptimized rectification method and electrolysis conditions; applied to mass production control criteria
StatusReviewing application to large components
03Root Cause Analysis of Appearance VariationAn analysis technology that identifies the causes of coating appearance variation through SEM-EDS and process-stage tracing.OutcomesEstablished a root-cause procedure for appearance variation; established a framework for agreeing appearance criteria
StatusOperated as a standard analysis procedure
04Cross-Section Coating Thickness VerificationA measurement technology that directly verifies coating thickness on areas with different surface conditions by the microscopic cross-section method.OutcomesDemonstrated equal thickness on forged and machined surfaces
StatusApplied as the standard method for checking thickness by area
05Chemical Conversion Coating ProcessA chromate conversion coating process to MIL-DTL-5541 and the dedicated line technology.OutcomesDesigned comparison tests by pretreatment route
StatusEvaluation of prototype appearance, corrosion resistance and electrical contact properties in progress
06Black-Dyed Anodizing of 7075A process technology that achieves both a uniform black appearance and coating performance on high-strength 7075 alloy.OutcomesBuilt a test framework to identify the stage at which stains occur
StatusStandard conditions to be finalized after prototype measurement
Technical Resources
Research results and literature summaries are published in Resources › Research Papers, and cited standards in Standards.
EF Technology systematically collects and manages domestic and international academic literature, published patents, and material and surface treatment standards. Every research note is linked to its source literature, and process control criteria are finalized based on in-house testing and customer approval, not external literature.
