Features
CNC machined aluminum die-cast radiator. Our heat sinks are widely used in communications, machinery, automobiles, wind power generation, engineering machinery, air compressors, railway locomotives, household appliances and other fields. Our target customers include mid-to-high-end customers in Asia, North America, Europe, Israel, Japan, South Korea, Malaysia, Singapore and other regions.
a. Light weight
Our radiators are made of innovative aluminum alloy, which is much lighter than traditional radiators.
b. Strong corrosion resistance
Our radiators are made of aluminum and zinc alloy, ensuring a long service life even under wear and tear conditions.
c. High temperature resistance
We pay great attention when designing the radiator so that it can withstand high temperatures without losing functionality.
d. Optimum heat dissipation
Our radiator’s superior heat dissipation capability is its main selling point.
Process
1 Aluminum die casting
Equipment & Contents
Equipment: One 300-ton die-casting aluminum machine
Contents: ADC12
Contents: ADC12
Process Characteristics
- The furnace temperature is 670°±20°, and the material handle is 20±2 mm.
- It is impossible to utilize secondary materials.
- Material composition must be tested to ensure it is suitable for production.
- After die casting, the first piece must be confirmed.
Note
- 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.
- Pay attention to the surface to prevent poor ejector pin crown, mold pulling or mold sticking.
- 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.
2 Take out the nozzle (saw nozzle) and pull out the slag bag
Equipment
Hydraulic Press
Note
- Pay attention to the surface and don't damage it or use insufficient material.
- Manage size and appearance.
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.

10 100% visual inspection (appearance) before powder coating
Details & Consumables
Thoroughly inspect the goods and packaging.
Consumables: dividers, containers, bubble wrap and desiccant.
Consumables: dividers, containers, bubble wrap and desiccant.
Note
- 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!
- The pass and stop inspection requirements of the tooth profile must be met.
- After the product is inserted into the knife card, the top layer is covered with a flat cardboard and wrapped.

Frequently Asked Questions (FAQ)
Q1: What industries are your aluminum die-cast radiators used in?
Our radiators are widely applied in communications, machinery, automobiles, wind power generation, engineering machinery, air compressors, railway locomotives, household appliances, and other related fields.
Q2: What regions and markets do you focus on?
We focus on mid-to-high-end customers in Asia, North America, Europe, Israel, Japan, South Korea, Malaysia, Singapore, and other global regions.
Q3: What materials are used in the die-casting process?
We use high-quality ADC12 material in our 300-ton die-casting aluminum machine. Secondary materials are strictly not utilized in order to maintain structural integrity.
Q4: How do you ensure the precision of the mechanical dimensions?
We implement strict IPQC, FQC, and OQC inspections using professional tools such as calipers, projection, 3D measurements, pin gauges, and tooth gauges, ensuring all measuring instruments are within their calibration windows.
Q5: What are the core product features of your heat sinks?
Our heat sinks feature lightweight construction due to innovative aluminum alloys, strong corrosion resistance via aluminum-zinc alloys, high temperature resistance, and optimum heat dissipation performance.
Q6: What steps are taken before powder coating?
We perform a 100% visual inspection based on reference samples to check for surface defects like dents or scratches, verify tooth profile pass/stop requirements, and wrap the products securely using dividers, bubble wrap, and desiccant.
