Yes, the same MPCVD equipment can be fully shared for producing both lab‑grown diamonds and diamond heat sinks.

This is not a theoretical conjecture but a mature solution validated by industry practice. Various data have demonstrated that the same MPCVD platform can be flexibly switched to produce these two different products. The shared use of MPCVD equipment is rooted in the same underlying technical principle, i.e., microwave excitation of carbon‑containing gases (mainly methane and hydrogen) to form a plasma, causing carbon atoms to deposit and grow on a substrate. Whether for lab‑grown diamonds (single crystal) or diamond heat sinks (mostly polycrystalline), the fundamental growth process is identical.

However, the growth processes for the two are not directly interchangeable; the process windows—in terms of gas pressure, power density, temperature field, and deposition rate—differ considerably between the two material types.

Wattsine offers a modular process switching solution. Its HMPS series MPCVD equipment supports storage and switching of parameter recipes, catering to enterprises' dual needs for small‑batch single‑crystal R&D and polycrystalline heat‑sink mass production.
