Frequently Asked Questions
Aluminum alloys are preferred for weight reduction and better thermal conductivity, while cast iron is used for extreme durability and heavy-duty industrial applications.
Gravity casting is more cost-effective but offers lower precision. Die casting involves forcing molten metal into a mold under pressure, resulting in higher precision and faster production cycles.
In sand casting, specialized sand cores are installed within the upper and lower dies to create the hollow internal passages necessary for coolant flow.
Yes, we provide full OEM services including precision machining of threaded holes, positioning pin holes, and specific cylinder cavity boring using milling and boring tools.
The price is primarily determined by the chosen material, the casting process (sand vs. die), the complexity of the size, and the degree of post-casting machining required.
We utilize controlled heating cycles (up to 350°C) and precision machining of mating surfaces to ensure an airtight and watertight seal upon assembly.
