Aluminum Die Casting CNC Machining Heat Sink

Our heatseak focus on mid-to-high-end customers in Asia, North America, Europe, Israel, Japan, South Korea, Malaysia, Singapore and other regions, and are used in communication, machinery, automobiles, wind power generation, engineering machinery, air compressors, railway locomotives, household appliances, etc.

Features

CNC Machined & Die-Cast

CNC machined aluminum die-cast radiator designed for mid-to-high-end global industrial applications.

Light Weight

Our radiators are made of innovative aluminum alloy, which is much lighter than traditional radiators.

Strong Corrosion Resistance

Our radiators are made of aluminum and zinc alloy, ensuring a long service life even under wear and tear conditions.

High Temperature Resistance

We pay great attention when designing the radiator so that it can withstand high temperatures without losing functionality.

Optimum Heat Dissipation

Our radiator’s superior heat dissipation capability is its main selling point.

Process

Step 1

Aluminum die casting

Equipment & Specifications

Equipment: One 300-ton die-casting aluminum machine

Contents: ADC12

Process characteristics:

a. The furnace temperature is 670°±20°, and the material handle is 20±2 mm.

b. It is impossible to utilize secondary materials.

c. Material composition must be tested to ensure it is suitable for production.

d. After die casting, the first piece must be confirmed.

Note

a. It is necessary to verify the filling quality of the surface. It’s not the bulge, it’s not the cold insulation, it’s not the lack of material in the pillars.

b. Pay attention to the surface to prevent poor ejector pin crown, mold pulling or mold sticking.

c. For non-machined surfaces and machined surfaces, the ejector pins are concave by 0-0.2 mm. The convexity of the ejector pin must be 0-0.2 mm.

Step 2

Take out the nozzle (saw nozzle) and pull out the slag bag

Equipment

Hydraulic Press

Note

a. Pay attention to the surface and don't damage it or use insufficient material.

b. Manage size and appearance.

Step 3

IPQC inspection

Testing Tools

Calipers, projection, 3D, visual inspection of appearance are examples of testing tools.

Precautions

Check dimensions against drawings and use accurate measuring equipment.

Step 4

Shape Product front shape

Equipment

Hydraulic presses, forming tools and blade rulers

Precautions

Within 0.25 mm from the front plane of the product.

Step 5

IPQC inspection

Inspection Details

Appearance visual assessment

Step 6

Shape the back of the product

Tools

Forming tools, blade ruler

Note

Within 0.15mm from the large surface of the product

Step 7

Tapping and drilling

Specifications & Equipment

Use the following equipment to drill D2.05 hole depth 6 and tap M2.5 hole depth 5.5: height gauge, bottom hole pass gauge, M2.5 pass gauge

Precautions

Avoid contact with scratches, flange burrs, missed taps, broken taps and residual metal fragments.

Step 8

IPQC INSPECTION Visual inspection

Inspection Details

Visual check parameters for surface finish and structure.

Step 9

Chemical conversion film for cleaning and leather coating

Precautions

No obvious color, unclean, no contact, no scratching

Step 10

100% visual inspection (appearance) before powder coating

Inspection & Consumables

Thoroughly inspect the goods and packaging

Consumables: dividers, containers, bubble wrap and desiccant

Note

a. Appearance needs to be checked based on samples. There should be no dents, scratches or other blemishes on the surface and the glue application should be smooth and flawless!

b. The pass and stop inspection requirements of the tooth profile must be met.

c. After the product is inserted into the knife card, the top layer is covered with a flat cardboard and wrapped.

Step 11

FQC exam

Testing Instruments

Calipers, projectors, pin gauges, tooth gauges, visual and packaging inspection are all examples of testing instruments.

Note

If the measuring device is still within its calibration window.

Step 12

Shipping notes

Note

a. Confirm that the amount matches the order.

b. Label and stamp the outer box.

c. Send reports on shipments.

Step 13

Qualified transportation inspection

Testing Instruments

Calipers, projectors, pin gauges, tooth gauges, visual and packaging inspection are all examples of testing instruments.

Precautions

Verify that the measurement device is still within its calibration window. Whether it meets both customer and SIP requirements.

Step 14

OQC shipment inspection

Testing Instruments

Testing instruments include calipers, projectors, pin gauges, tooth gauges, outer packaging inspection, etc.

Note

If the measuring device is still within its calibration window. Whether it meets both customer and SIP requirements.

Frequently Asked Questions (FAQ)

Q What industries and applications are these heat sinks designed for?

Our heat sinks are widely used in communication, machinery, automobiles, wind power generation, engineering machinery, air compressors, railway locomotives, household appliances, and other fields.

Q What are the main performance advantages of your CNC machined die-cast radiators?

They offer four key advantages: light weight (due to innovative aluminum alloy), strong corrosion resistance (made of aluminum and zinc alloy), high temperature resistance without losing functionality, and optimum heat dissipation performance.

Q Which regions are your target market customers located in?

We focus on serving mid-to-high-end customers located in Asia, North America, Europe, Israel, Japan, South Korea, Malaysia, Singapore, and other global regions.

Q What material and equipment are used in the die casting process?

We utilize high-quality ADC12 material and process it using a 300-ton die-casting aluminum machine. Our process strictly avoids the use of secondary materials and requires material composition testing before production.

Q How do you guarantee product quality during production and before shipping?

Our quality control includes multiple IPQC inspections throughout the forming, tapping, and cleaning stages, followed by a 100% visual inspection before powder coating. Finally, we execute rigorous FQC, Qualified Transportation, and OQC shipment inspections using calibrated instruments like calipers, projectors, pin gauges, and tooth gauges to meet customer and SIP requirements.
