IN Brief:
- TactoTek has signed Suzhou Rixian Optical Technology as a licensee for IMSE design-phase validation in China.
- The agreement adds local rapid prototyping for functional IMSE parts used in automotive smart surfaces and lighting.
- The move supports structural electronics development as vehicle interiors and exteriors become thinner, lighter, and more interactive.
TactoTek has signed a licensing agreement with Suzhou Rixian Optical Technology to expand design-phase validation capability for In-Mold Structural Electronics in China.
Under the agreement, Suzhou Rixian will provide rapid prototyping of fully functional IMSE parts for local automotive OEM development programmes. The company is based in Suzhou and specialises in automotive lighting prototype services, including CNC optical prototypes, silicone moulding for low-volume manufacturing, 3D-printed plastic components, and high-precision optical prototype production.
TactoTek’s IMSE technology integrates lighting, touch controls, electrical components, and circuitry directly into three-dimensional moulded structures. The approach replaces conventional multi-component assemblies with smart surfaces that can combine electronic function, mechanical structure, and decorative finish in a thinner and lighter format.
The licensing agreement gives Chinese vehicle developers a local route for early-stage IMSE prototyping and design iteration. Structural electronics depend on mechanical, optical, electrical, and aesthetic design choices being validated together rather than treated as separate workstreams.
Automotive lighting and interior controls are among the clearest applications. Vehicle manufacturers are moving toward illuminated emblems, interactive trim, capacitive control surfaces, ambient lighting, and exterior communication elements. These functions are difficult to package neatly using conventional assemblies of circuit boards, wiring, light guides, diffusers, mechanical carriers, and decorative layers.
IMSE compresses those layers into moulded structures, reducing assembly complexity, part count, weight, and thickness. It also allows designers to place electronic functions into shapes and surfaces that would be awkward or impossible with rigid PCB-based assemblies. The technology still requires early validation because changes to geometry, materials, printing, optics, moulding, and electronics can all influence the finished part.
Rapid prototyping is central to that process. A smart illuminated panel or touch-enabled surface needs to be evaluated for optical uniformity, tactile response, electrical performance, thermal behaviour, durability, appearance, and manufacturability across multiple iterations. Local prototyping shortens the loop between design intent and working demonstrator.
The China focus adds a commercial and engineering dimension. Chinese automotive development cycles are among the fastest in the world, particularly in electric vehicles and digitally differentiated interiors. Suppliers that support fast local iteration can influence platform decisions before designs are frozen.
The agreement follows wider development of TactoTek’s IMSE ecosystem across prototyping, manufacturing, and application development. Structural electronics sit between printed electronics, injection moulding, optical design, human-machine interface development, and automotive-grade qualification, making ecosystem depth important to production adoption.
IMSE changes the boundary between circuit and structure. Conductive traces, components, lighting elements, and user-interface functions are no longer confined to flat boards mounted behind a surface. They become part of the surface itself. That can reduce packaging volume and open new user-interface concepts, while forcing electrical design to be considered alongside mould flow, decoration, mechanical stress, and long-term reliability.
Suzhou Rixian’s role as a lighting prototype specialist gives the partnership a practical starting point in optical validation, a critical step for automotive smart surfaces. As vehicles continue to merge electronics with interior and exterior design, local design-phase validation will play a larger role in moving structural electronics from demonstrators into production programmes.
