Product Overview
What Are Heat Sinks & Thermal Components?
Heat sinks and thermal components transfer heat away from electronic devices, power modules, motors, LED systems and industrial equipment. Their performance depends on thermal conductivity, contact quality, airflow design, surface condition and manufacturing precision.
OEM thermal management parts may include extruded heat sinks, CNC machined heat sinks, skived fin components, liquid cold plates, thermal housings and interface plates. FSD supports custom thermal component manufacturing through material review, process selection, machining, finishing and inspection.
Heat sinks and thermal components can also be reviewed for EV charging and power electronics applications where heat-dissipation geometry and mounting interfaces are defined by the assembly.
For energy-related applications, these thermal components can also be reviewed as part of new energy and energy storage equipment projects.

FAQ
Heat Sinks & Thermal Components FAQ
What aluminum is best for heat sinks?
6063 aluminum is commonly used for extruded heat sinks because it supports extrusion and thermal performance. 6061 aluminum is often selected for CNC machined thermal components.
Should I choose CNC machining or extrusion for heat sinks?
Extrusion is suitable for repeatable fin profiles and higher volume applications. CNC machining is better for complex geometry, prototypes, precision interfaces and custom mounting features.
Can FSD customize thermal components?
Yes. FSD supports custom heat sinks, machined thermal components, extruded heat sinks, cold plate components and thermal housings based on CAD drawings and application requirements.
What drawings are required?
Provide 3D CAD files, 2D drawings, material requirements, quantity, surface finish notes, interface requirements and any thermal performance expectations for engineering review.
Can you support prototype heat sinks?
Yes. Prototype heat sinks can be reviewed and manufactured through CNC machining before moving toward extrusion, tooling or production manufacturing after validation.
How does surface finish affect thermal performance?
Surface finish affects protection, durability, appearance and interface contact quality. Critical thermal contact areas may require flatness and roughness control.
What inspection is required?
Typical inspection includes flatness, dimensional checks, surface roughness review, interface inspection and finish verification for critical thermal areas.
How do I select thermal components?
Selection depends on heat load, airflow, material, fin geometry, interface contact, production volume, finish requirements and inspection needs.
