SK-4012H is a versatile model in our CNC Machine Tools lineup, designed for manufacturers producing both air cooling and liquid cooling heat sinks.
The machine adopts double shaft structure matched with thickened linear rails, which bears heavier load and maintains precise positioning during long-hour continuous operation. Its maximum cutting length reaches 1200mm, supporting aluminum width up to 380mm and copper raw material up to 200mm.
With adjustable shovel chip thickness from 0.15–1.0mm, this equipment balances production speed and processing range, suitable for medium-batch mixed radiator manufacturing orders.

1、Independent R&D & Authorized Patents
We hold nearly 100 authorized patents focusing on shovel tooth processing and heat sink manufacturing technology. Our production bases cover the Guangdong-Hong Kong-Macao Greater Bay Area, Yangtze River Delta and Southeast Asian markets, building integrated supply chain support for global thermal solution clients. We coordinate multi-site production capacity to provide flexible, one-stop manufacturing solutions for liquid cooling and air cooling factories.
2、Stable Business Capacity Growth
Our operation scale maintained steady growth from 2020 to 2024:
2020: Annual revenue RMB 355 million, mainly fan heat dissipation accessory manufacturing
2024: Annual revenue RMB 1.094 billion, liquid cooling products account for over 30% of turnover
We launched mass liquid cooling radiator production in 2023, expanding our full range CNC Machine Tools including heavy-load SK-4012H to cover diversified heat sink processing demands.
SK-4012H equips reinforced dual linear rails to carry heavier processing loads, with 1200mm longer cutting stroke, suitable for mixed production of air cooling and liquid cooling heat sinks of medium batch size.
