日栄 List of Products and Services

Nihon Ei aims to realize the vision of development engineers for the ideal resin gears of the times. We support the challenge of manufacturing by investing all our technical expertise and equipment resources, from consulting to materials, prototyping, testing, verification, durability evaluation, and molding. <<Past Consultation Topics>> ■ We want to create lightweight yet highly durable resin gears. ■ We want to achieve quiet operation even in high-load and high-speed environments. ■ We previously attempted to use resin but gave up because we couldn't identify the cause. ■ With so many demanding requirements, it's impossible to achieve this with plastic, right? Nihon Ei realizes high-level metal alternatives through super engineering plastic injection molding. *For more details, please refer to the PDF document or feel free to contact us.
