Yes — SunYin Sapphire accepts small trial batches of sapphire HUD heat-dissipation screens below standard production quantities. A single unit can be sampled for qualification, and runs of 100+ pieces are where unit pricing becomes most efficient. Prototypes run 1–2 weeks; mass production about one month.
Why automotive programs start small
A sapphire HUD thermal screen has to prove optical clarity and heat-spreading performance inside a vehicle-grade module before volume tooling is locked. A small qualification batch lets your optical and thermal team validate the part, then scale to production without re-qualifying.
Why we can take small batches
Sapphire is our own process from crystal growth to coating — not a brokered resale — so a trial run does not depend on an outside supplier's minimum. Coating runs in an ISO Class 6 cleanroom on Showa and Hanil lines covering both high-precision AR stacking and large-size coatings.
