NCC Product Lineup

**Customer Concerns** - Defects caused by dust and foreign objects occurring in existing paint rooms and booths. - Consultation with NCC regarding the complete removal or installation of paint booths and the establishment, manufacturing, and installation of paint rooms with thorough measures against dust and foreign objects for mass production of new products. **NCC's Proposal** We propose the use of an "intake filter" to purify the air supplied within the paint room and a "3-in-1 multi-dry filter R" to purify compressor air, aimed at suppressing defects caused by dust and foreign objects. **Implementation Effects and Feedback** - Even after one month of operation, there have been no defects in painting caused by dust, foreign objects, or compressor air. - We are glad we chose to consult with NCC, which has a high sensitivity to measures against dust, foreign objects, and painting defects.

**Customer Concerns** - Holes have formed in the eliminator of the water-based painting booth, making it difficult to adequately capture paint mist. - Paint mist that passes through the eliminator adheres to the fan, causing unusual noises. - Concerns about the impact on neighboring areas. **NCC's Proposal** We propose the introduction of a water-based painting booth made with thick steel plates that have high resistance to corrosion, preventing the formation of holes and allowing for long-term use. **Implementation Effects and Feedback** - The noise from the fan has decreased compared to before. - The collection efficiency has improved. - NCC handles all aspects of the project, including dismantling, removal, waste disposal, new installation, and duct work, eliminating hassle and burden.

**Customer Concerns** - The painting work is concentrated at the headquarters factory, and we want to reduce the burden. - We want to establish risk avoidance measures for emergencies like disasters or the COVID-19 pandemic. - The operating hours of the headquarters factory are very long, resulting in a significant burden on the workers. **NCC's Proposal** We propose utilizing the available space at the subsidiary factory with a compact "powder coating equipment" that can also accommodate space-saving needs. **Implementation Effects and Feedback** - The painting burden at the headquarters factory and the burden on workers have been alleviated. - A greater than expected reduction in defect rates.

**Customer's Concerns** - Loss of time due to the outsourcing of powder coating operations, resulting in delays in the movement of coated items. - Considering in-house powder coating and wanting to expand equipment. - Inefficient work due to the long curing time of the existing solvent booth. **NCC's Proposal** Proposing a powder coating line that allows for a consistent workflow for painting-related tasks and a custom-made large painting booth with improved air supply to reduce work time. **Implementation Effects and Feedback** - Comparing before and after implementation, production capacity has nearly doubled.

【Customer's Concerns】 - Traditional paint booths have become dust collectors due to the effects of negative pressure, leading to frequent occurrences of dirt and foreign material defects. - Although efforts were made internally to improve the defect rate, significant results were not achieved. 【NCC's Proposal】 We propose a total coordinated painting line that reduces the defect rate and improves workability. 【Implementation Effects and Feedback】 - The previously problematic defect rate has been significantly reduced. - Productivity has also improved.

**Customer's Concern** - The unusual noise and vibration from the exhaust fan of the large painting booth being used is causing stress. **NCC's Proposal** We propose the "Professional Cleaning Service," which specializes in the manufacturing and maintenance of exhaust systems, to remove the large amounts of paint residue that have accumulated. **Implementation Effects and Feedback** - After implementation, there were no more abnormalities with the exhaust fan, making work comfortable. - The cleaning resulted in a noticeable improvement in the working environment. - Prevented the occurrence of painting defects in advance.

**Customer Concerns** - The micro motor core is coated with a thick layer of powder coating that has insulation properties, with half of the coating process done in-house using electrostatic painting and the other half externally using fluidized immersion coating. - Due to the aging of both in-house and outsourced equipment involved in the coating process, there are difficulties in obtaining parts and issues with the quality of the coating appearance, such as gloss. - They are looking for a reliable consulting partner to achieve complete in-house coating. **NCC's Proposal** We propose a "fluidized immersion powder coating machine" that can accommodate a wide variety of core shapes and allows for flexible thickness management to improve coating quality. **Implementation Effects and Feedback** - Improved quality resulting in a glossy coating. - The coating hardness meets the requirement to withstand strong friction when copper wire is wound around it. - Enhanced insulation performance due to improved coating quality. - A reduction in powder usage by 30-40% due to high coating efficiency. - Anticipated cost reductions across the entire coating process in the future.
