Colonis's Work
Synthetic resins are now indispensable in our daily and social lives. For over 30 years, Coronis Co., Ltd. has provided customers with products made from this versatile and highly convenient material.
We combine our cultivated processing expertise and solid experience with state-of-the-art equipment, offering meticulous responsiveness to meet your needs.
The Engineer's Vision
We place particular emphasis on quality in our production.
For example, the indoor temperature at our machining plant.
To minimize thermal expansion and contraction, we maintain a constant temperature of 25 degrees Celsius year-round.
Furthermore, our policy is to accommodate customer quality requirements whenever possible. To this end, we maintain equipment including 3D measuring instruments, surface roughness testers, projectors, and dimensional magnification microscopes.
We perform inspection on all items to ensure compliance with requested inspection criteria before shipment.
