Bodies, brackets, and extensions for automotive lamps
These products for automotive lamps achieve both functionality and design appeal through advanced injection moulding technology and quality control systems.

Film insert products
These products achieve high design appeal by insert moulding (simultaneous moulding) a film onto the surface or back. We are working on further development to add new possibilities to synthetic resin products, such as moulding methods that support three-dimensional shapes and combinations with three-dimensional wiring.

Millimetre-wave radar compatible emblems
By constructing emblems, the "face" of the brand, using insert moulding with a metallised printing film (metal-free) with added three-dimensional shapes to avoid interference with millimetre waves, we have added the function of a millimetre-wave radar cover.

Inner lenses and light guides for automotive lamps
These are thick-walled lenses with a continuous prism structure, built into automotive lamps, that enhance vehicle visibility by lighting up and flashing in various patterns using LED light sources, contributing to the safety of pedestrians and occupants, while also reflecting the designer's intent to express the individuality of the brand and vehicle. With the advancement of high-performance LED light sources, the lenses themselves are becoming increasingly complex three-dimensional shapes.

Aspheric (freeform) lenses
Aspherical (freeform) lenses that control the light distribution of automotive headlamps, these are extremely important products for protecting the safety of pedestrians and occupants. With the shift to LED light sources for headlamps, there is a rapid replacement of conventional glass lenses with synthetic resin ones, which also contributes to improved environmental performance through weight reduction.

Clinical diagnostic containers
These are medical components necessary for tests to determine the presence of illness and for disease management. They are containers for holding samples and separating precipitates from supernatant through centrifugation. We also support secondary processing such as sterilisation according to customer requirements.
