Who We Are
ROTADIE is a precision die-cutting and converting factory based in Shenzhen, China — one of the world's largest electronics manufacturing hubs. We specialize in converting functional materials into custom die-cut parts: adhesive tapes, foams, insulating films, EMI shielding materials, protective films, dust-proof meshes, thermal interface materials and multi-layer laminated assemblies.
What We Do
We work from your drawing — DXF, PDF or a physical sample. Our engineers select the right material stack-up for your application, advise on tolerances and DFM (design for manufacturing), build the die tooling, and run production with in-process inspection. From a single prototype run to recurring mass production, every part ships with 100% outgoing inspection.
Who We Serve
Our die-cut parts are used in consumer electronics (smartphones, TWS earphones, wearables, smart speakers), automotive electronics (dashcams, sensors, infotainment), medical and hearing devices, security cameras, LED lighting and industrial control equipment. We ship worldwide with export-standard packing.
How We Work
One engineer is assigned to your project from quotation to delivery. Material selection advice, tolerance feedback and sampling are handled in-house — no broker, no middleman. Fast sampling (as fast as 48 hours for standard designs) keeps your project validation moving.
Why ROTADIE
- Custom per drawing — every part is made to your spec, not from a catalog.
- Factory-direct — in-house slitting, laminating and die-cutting, transparent pricing.
- Fast response — quotation in 1–2 working days, sampling in as fast as 48 hours.
- Verified quality — incoming, in-process and 100% outgoing inspection, dimension report on request.
