Acetate Frames
Precision CNC machining is paired with hinge work, core-wire processing, tumbling, hand polishing and final fitting. Material thickness, color placement and edge character are considered from the first engineering review.


Japanese Eyewear Manufacturing
We match product requirements to the right Japanese factory, process and specialist partner.
Your design determines the route.
EIDAI provides a strong manufacturing base in injection molding and acetate CNC. Sabae Optical expands from that core into Japan's wider eyewear production field.
We coordinate the material, process, component and finishing requirements that turn a product definition into a finished frame.
Design intent, quantity, price position and timing are translated into viable manufacturing decisions.
Frame materials, components, lenses and finish standards are defined as one connected specification.
Each operation is assigned to the Japanese factory or specialist best suited to the requirement.
Samples, approvals, finishing, assembly and inspection remain visible through one project route.
Each category can stand alone or connect to a broader frame program with coordinated components, lenses, finishing and final assembly.

Lightweight constructions are developed with Japanese partners experienced in forming, joining and precise frame completion. Bridge geometry, rim profiles, temple systems and surface specifications are coordinated as one product.

EIDAI connects mold engineering, 3D prototypes, tooling, robotic handling and secondary processing in one route. The program can continue through coloring, lens fitting, assembly and final inspection.

Specialist metal production supports refined optical and sun frames in stainless steel and selected alloys. Structural choices, soldered or joined details, components, plating and final fit are reviewed together.

Acetate and metal systems brought together through coordinated engineering, component sourcing, fitting and finishing.

Prescription-ready programs cover acetate, titanium, metal, injection and combined material constructions. Lens interface, eyewire consistency, size grading, nose fit and final adjustment are considered for reliable everyday use.

Fashion and performance sun styles are developed with coordinated frame, lens, color and finishing requirements. Lens base curve, tint direction, coatings, fit and assembly method enter the same technical review.

Japanese sourcing for hinges, core wires, nose pads, lenses, cases and related components, aligned to the frame program.

Uncommon details deserve a direct technical review. We identify suitable Japanese partners for specialist surfaces, laser work, custom components, decorative treatments and finishing operations outside a standard frame route.

A complete specification is useful, but it is not required. We can begin from different levels of product definition and clarify the next engineering decision.
For brands defining a new construction, material direction or market position before detailed engineering.
For teams ready to test dimensions, structure, manufacturability and the path toward a first physical sample.
For sourcing teams seeking a suitable Japanese factory route, quotation structure and controlled production handoff.
For a component, finish or technical detail that requires targeted partner research rather than a standard program.
Yes. Send sketches, reference samples, preliminary CAD or a production-ready package. We identify the engineering decisions required before sampling.
No. EIDAI is a core manufacturing base, while additional Japanese specialists are coordinated when the material, component or finishing requirement calls for them.
Programs may include acetate, injection, titanium, metal and combination frames, plus optical frames, sunglasses, lenses, parts, cases and accessories.
Yes. The exact scope is confirmed project by project and aligned with the frame specification, destination market and final delivery requirements.
Share the product type, target material, drawings or references, expected quantity, timing, destination market and any known testing or packaging requirements.
Send the design and the decisions already made. We will focus the first review on what still needs to be resolved.
