The design focuses on depth, proportion and material contrast.

Rather than relying on decorative elements alone, different surface levels are introduced into the acetate front to create a more dimensional appearance. The translucent material further enhances the effect by allowing the contours and polished edges to remain visible from different viewing angles.

The temple continues this design language through contrasting acetate and a carefully controlled transition from a wider front section to a slimmer rear profile.

Multi-Level Front Design

One of the key features of this frame is its multi-level acetate front.

Different depths, contours and surface heights are created around the eyewire, giving the frame greater dimension than a conventional flat acetate front.

Transparent and translucent acetate make these details particularly visible, as light interacts with the different surfaces and polished edges.

The depth, width and contour of each level can also be adjusted during custom development to create different visual effects.

Two-Part Acetate Temple Design

The temple uses a two-part acetate construction, combining a patterned acetate section near the hinge with a contrasting acetate section forming the main temple body.

The main temple section is shaped with a wider front connection area and a slimmer rear profile. The patterned acetate is precisely joined to this wider front section, creating a clear contrast between the two materials while maintaining a smooth, flush surface after finishing.

This construction allows different acetate patterns and colors to become part of the temple structure itself, rather than simply adding a decorative surface effect.

Manufacturing & Engineering Highlights

5-Axis CNC for Multi-Level Structures

For more complex multi-level designs, 5-axis CNC machining can be used to create different depths, angled surfaces and three-dimensional contours directly from the acetate material.

Compared with a simple flat cutting process, multi-axis machining provides greater control over the relationship between each surface and helps maintain consistency across the frame.

For less complex structures, the dimensional effect can also be achieved through controlled multi-step CNC machining and milling according to the design.

The machining program, tool path and cutting depth are adjusted according to the required geometry so that the intended levels remain clearly defined before finishing.

Acetate Lamination & Temple Shaping

The contrasting temple detail is created by joining two different acetate sections—a patterned acetate section near the hinge and a second acetate color for the main temple body.

The main temple section retains a wider area at the front for the laminated connection, while the rear section is machined into a slimmer temple profile.

After the two acetate sections are precisely joined, further machining and finishing ensure:

* A clean junction between the two acetate colors
* Accurate matching between left and right temples
* A smooth, flush surface at the joined area
* A well-defined wider front section and slimmer rear temple profile

This process integrates the acetate color combination directly into the temple construction, creating both structural and visual detail.

Surface Finishing & Polishing

For transparent and multi-level acetate frames, polishing quality directly affects how clearly the dimensional structure can be seen.

During the tumbling stage, we use Italian-imported high-gloss polishing compound, helping the acetate achieve a smooth and bright surface even before final hand polishing.

Experienced polishing technicians then work from multiple angles, paying particular attention to the layered contours, edges, corners and laminated transition areas.

The objective is not simply to make the frame glossy. The polishing process must also preserve the CNC-defined levels and fine structural details, while achieving a clean and refined surface.

Custom Development

The multi-level structure can be adapted to different frame shapes and design concepts. Acetate colors, patterns, laminated combinations, CNC contours and temple proportions can all be developed according to project requirements.

This gives brands more flexibility to create their own dimensional acetate designs rather than simply changing the color of an existing frame.

 

FAQ

How is the multi-level front structure produced?

Depending on the complexity of the design, the different depths and contours can be produced through 5-axis CNC machining or controlled multi-step CNC machining. This allows the surface levels to be accurately defined before polishing.

Can the depth of the different levels be customized?

Yes. The depth, width, contour and positioning can be adjusted according to the frame design and desired three-dimensional effect.

How is the contrasting temple effect produced?

Different acetate colors or patterns can be combined through laminated acetate construction, followed by precision machining and finishing to create a smooth transition and the required temple profile.

Can different acetate colors and patterns be combined?

Yes. Transparent, translucent, solid and patterned acetate can be combined according to the design concept and material compatibility.
