• - 8 units of injection molding machines for mass producing heating panels: Capa. 10,400 tons/year

  Sales (Oct. 2021 – Feb. 2022): 400 million KRW, Employment creation: 15 employees

Technology issuesThe company requested technology support and advice to address issues of quality deterioration of the products and increase in the cost of prototype development due to rough surface and defects on the surface of the 3D-printed objects.

Technology support The causes of defects on the surface of the objects are identified. The surface quality of 3D-printed objects is improved by controlling process conditions including the arrangement of objects, powder filling rate, and gas flow rate.

Surface of objects according to process conditions of 3D printing

Outcomes of technology supportReduced cost and defect rate thanks to improved surface quality of the objects

• - Saved 24 million won as prototype development took 6 months less
• - Defect rate of the object manufacturing is decreased by about 30%.

Technology issuesSince there are no clear reliability evaluation methods of VCSEL, the company requested technology advice for VCSEL lifetime evaluation and warranty life calculation to ensure the reliability of their products.

Technology supportThe causes of errors in the company’s reliability evaluation are analyzed. Arrhenius model is applied to a new formula for accurate lifetime prediction. Analysis of VCSEL reliability database found that the failures of VCSEL have to do with degradation. Data analysis methods using B10, B50 reliability levels and Weibull distribution that are suitable for degradation are proposed.

Outcomes of technology supportEstablished reliability evaluation and data analysis methods can provide accurate reliability data to companies. High reliability can lead to new export trade partners.

• - Sales of 6.7 billion KRW in 2020. Sales of 9.1 billion KRW in 2021. Forecast of 12 billion KRW in 2022.
