The Workshop, Up Close.
Three materials, four signature techniques, one team. Acetate, combination, titanium — produced under one roof, by one workforce, against one standard. Below: the patented and proprietary techniques that separate CIC from generic OEM.

Four Methods, One Workshop.
CIC ships standard acetate, combo, and titanium at scale — but the work below is what partner brands quietly buy us for. Patented pressing, proprietary mold libraries, and an automated lamination cell rare in Heyuan.

The Push-Thru Technique.
Patented pressing method — China patent ZL 2015 1 0558145.8 (Wang Daomin). Eliminates the step-down effect of traditional lamination.
Heat and pressure push coloured acetate layers through other layers on the same plane via a mold, producing a smooth multi-coloured surface with vibrant depth and dimension. Unlike step-milled lamination, Push-Thru runs in 2-layer (1.0 mm + 5.0 mm) or 3-layer (1.0 mm + 0.5 mm + 4.5 mm) constructions, and two 3-layer Push-Thru fronts can be laminated together for a 6-tone effect popular in the French market.
- Method
Heated mold press through coloured layers on a single plane — no step-down.
- Construction
2-layer 1.0 + 5.0 mm · or 3-layer 1.0 + 0.5 + 4.5 mm.
- Custom molds
Wide pattern library — flowers, geometrics, brand marks.
- Sustainability
Zero acetone — traditional lamination requires solvent glue. Eligible for ISCC PLUS sustainable acetate.
- Cost
Lower than traditional lamination — fewer steps, no solvent, less waste.
- 6-tone effect
Two 3-layer Push-Thru fronts laminated together — popular in FR market.

Sculptural & Wrapped End-Pc.
Mold-pressed sculptural detailing with seamless wrapped end-piece construction. Density rises after pressing, so the front resists deformation over time. Unlike CNC engraving, mold work delivers a flawless, scratch-free surface with finer relief — and is faster and lower-cost than CNC.
- Method
Mold-pressed front and end-piece in one shot.
- Density gain
Pressing increases material density; reduces long-term warping.
- vs CNC
Smoother bevels, finer relief, no tool-mark artefacts.
- Use cases
Sporty wrap-arounds, bevelled fronts, signature side detailing.
- Throughput
Faster and more efficient than CNC sculpting.

Metal Inlay, Chain & Stone Lamination.
Stone-lamination process patented — China patent ZL 2016 1 0168786.7 (Wang Daomin). Metal and stone secured without pins, screws or glue.
Metal embellishments, silver chains, or stones laminated directly into the acetate body — top, sides, and all around the rim — secured without any pins, screws or glue. Automated lamination machinery gives flawless, repeatable results, and the metal can be plated for a richer, more colourful product.
- Method
Pressed and laminated — chains, plates, stones, foils, micro-text.
- No fasteners
Secured without pins, screws or glue. Nothing to loosen.
- Surface
No visible bond line, no inclusion bubbles.
- Consistency
Defect-free finish, machine-repeatable across runs.
- Use cases
Jewellery-grade acetate, hidden brand marks, plated chains.

Wrapped Push-Thru Fusion.
Confidential prototype — combined Push-Thru effect inside the wrapped end-piece area.
A new fusion concept: the Push-Thru colour effect rendered inside the Wrapped End-Pc area. Merges sport wrap silhouette with multi-tone editorial colour layering. Already previewed with select US and EU partners under NDA; first public showing at SILMO.
- Exclusivity
Net-new construction never seen in market — first-mover advantage for the partner brand.
- Design upside
Sport silhouette + editorial colour at the end-piece — new collection territory.
- Sampling
Bespoke molds per brand · NDA + sample protocol.
- Lead time
Quoted per project — typical 90–120 days first run.
