Frequently Asked Questions
What materials and process are used for High Power Heat Sink?
High Power Heat Sink is made from Tungsten copper (W–Cu), high-conductivity copper and is formed by MIM/PM (metal injection molding / powder metallurgy) near-net-shape and sintered to a relative density of ≥ 98%, which keeps mechanical properties close to wrought material.
What tolerances can High Power Heat Sink hold?
Typical as-sintered dimensional tolerance is ±0.3–0.5% of the dimension. Tighter tolerances are achievable with secondary sizing or machining, agreed per part during quoting.
What is the MOQ and lead time for High Power Heat Sink?
MOQ is 1000 pcs. Mold lead time is about 20 days (mold fee typically RMB 20–40k depending on part geometry), and production lead time is about 7 days once the mold is validated; secondary processing adds 3–5 days.
