Every Skived Fin Heat Sink Starts on Our Own CNC Skiving Equipment
BY Thermal (Dongguan Baoyue Technology Co., Ltd.) manufactures custom skived fin heat sinks using CNC skiving machines designed and built by our sister factory, Dongguan Weihang Industrial Co., Ltd. That is how we hold 0.05 mm fin thickness, control lead time end-to-end, and support your project from prototype to production under one roof.
Self-Owned Machines Mean Your Heat Sink Is Under Our Control
Most custom heat sink suppliers outsource skiving. BY Thermal doesn't — our machines are designed and built by our own team, so quality, cost and delivery stay in one factory.
Consistent Precision
In-house skiving holds tight fin geometry across every batch — no third-party tolerance drift, no rework surprises.
Controlled Lead Time
Prototypes ship in 15–25 days because we don't wait on external machine capacity. Scheduling is fully internal.
Cost Advantage
No machine-hour markup from external processors. You pay for the heat sink, not a middleman's equipment overhead.
Design–Build Loop
Our engineers tune machine parameters with our design team, so DFM feedback is real, fast and applied before quoting.
The Machines Behind Your Heat Sink
Five skiving machine platforms cover everything from compact prototypes to 3.5-meter industrial heat sinks. All five are designed and built by our sister factory, Dongguan Weihang Industrial Co., Ltd. — same owner, one group, full control over your production.
