Sandblasted 5-Axis CNC Milling Aluminum Alloy Hemisphere Heat Sink Housing Custom Precision Machining Light Housing Components

Brief Introduction

This custom 5-axis CNC machined aluminum hemispherical heat sink housing comes with sandblasted surface finish. Made of premium aluminum alloy, it features internal reinforcing heat dissipation ribs, side mounting lugs and flange bolt holes. With excellent thermal conductivity, high rigidity and uniform matte texture, it is widely used as heat dissipation shell for high-power LED lights, industrial lighting and special light sources. OEM & ODM custom machining service available, factory direct supply with reliable quality.

Product Overview

This dome-shaped lamp housing is manufactured by advanced 5-axis CNC milling. The hemispherical contour, internal heat sink ribs, side connection bosses and flange mounting holes are finished in one clamping process, ensuring high dimensional accuracy and perfect assembly fit. Sandblasting treatment removes machining tool marks and forms uniform matte metal surface, improving scratch resistance while maintaining good heat transfer performance.

All finished parts go through strict dimensional inspection before shipment. We accept custom manufacturing according to your CAD drawings or physical samples. Both prototype trial orders and mass production orders are supported.

FAQ

Q1: What material is this sandblasted aluminum hemispherical heat sink housing?

A: Standard material is 6061 aluminum alloy with sandblasted surface finish. We also support 6063 and 7075 aluminum alloy for custom orders.

• 6061: General purpose, balanced strength and machinability, most widely used for CNC heat sink housing parts.
• 6063: Excellent anodizing performance for uniform surface appearance.
• 7075: High-strength aerospace aluminum for heavy-load working conditions.

Q2: Can you produce according to my 2D or 3D CAD drawings?

A: Yes. Please send us your files in STEP, IGES or PDF format. Our engineering team will evaluate your drawing and provide quotation. We also accept physical samples for reverse engineering.

Q3: What is sandblasted finish? Can I choose other surface treatments?

A: Sandblasting is a surface processing method to create uniform matte metal texture and remove tool marks. Other available options include clear anodizing, black anodizing, brushing and polishing.

Q4: What is your MOQ? Can I order 1 piece for sample testing?

A: MOQ is 1 piece. We support prototype sample before mass production.

Q5: What is your production lead time?

A: Sample order: 3–7 working days. Mass production: 7–20 working days depending on order quantity.

Q6: How do you guarantee product quality?

A: We inspect dimensions with calipers, micrometers and CMM. Every part will be checked before packing. Inspection reports can be provided upon request.

Q7: What is T/T payment term?

A: T/T stands for Telegraphic Transfer, also known as wire transfer. It is the most common international payment method. For sample orders, we accept 100% T/T in advance. For bulk orders, common terms are 30% T/T deposit before production and 70% T/T balance before shipment.

Q8: Can you also make parts from stainless steel or alloy steel?

A: Sure. We manufacture custom turned and milled parts in aluminum, stainless steel, alloy steel, brass and engineering plastics.
