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.
