We uphold the company philosophy of technological innovation and people-oriented management. While introducing cutting-edge communication technology and equipment from abroad, we sincerely invite domestic talents who are dedicated to this field to join us.
Our strong R&D team provides customers with comprehensive services from design to process development and then to large-scale production.
Shanghai Yongyi adheres to the concept of "providing first-class services and producing first-class products for first-class customers" and has long served top customers in the optical communication industry. We can provide customers with the entire process from design and development to samples and mass production.

Through years of technical accumulation and experience, Shanghai Yongyi can help customers prepare for mass production during the design and development stage, avoiding problems such as long cycles, frequent changes, and high costs from design and development to mass production.

By introducing automated production and retaining core operational staff, Shanghai Yongyi has solved the problems of manual operations and low production flexibility in passive optical products. We have now reserved over 30% production capacity for customers' mass production, capable of withstanding normal production fluctuations. At the same time, in the face of sudden demand growth, we can complete capacity expansion within 2 to 4 weeks.

Shanghai Yongyi fully understands customers' cost reduction requirements and has the capability for continuous cost reduction by focusing on product development, process design, yield control, and other aspects. We can provide customers with products with sufficient price competitiveness, helping them gain an advantage in market competition.

We have a vibrant yet experienced R&D team that is daring and creative. Innovation is our driving force, and being distinctive is our relentless pursuit. The team possesses capabilities in optical design, process R&D, mechanical design, various fixture design and development, and various high-precision measurement and testing. Our technical strengths are:

(1) Sub-micron high-precision processing and measurement capabilities.

(2) Micron-level precision injection molding product design and manufacturing capabilities.

(3) Precision optical alignment, packaging, grinding, and optical performance testing capabilities.
Corporate Culture
Ideals are not practical things; they often cannot bring you worldly enjoyment. Therefore, you must get used to being unappreciated, learn to enjoy spiritual satisfaction, and learn to be different from others.

Overcoming yourself is more arduous and meaningful than conquering others. No matter how world trends change, people's excellent qualities are eternal: integrity, courage, and independence. Excellent enterprises also remain: focused, professional, and serious.

Ability is more important than academic qualifications, moral character is more important than ability, and income is based on contribution.

Management personnel are cultivated internally, and technical talents are continuously introduced.

There is no best talent, only the most suitable talent.

Emphasize cultivating and retaining talented individuals with good moral character who can create substantial value for the enterprise.
