Lost Wax Casting
Dimensional Accuracy: Our Heavy-Duty Precision Cast Carbon Steel Components boast exceptional dimensional accuracy, with tolerance grades ranging impressively between CT6-CT9. The stability of these dimensions ensures that they surpass the standards required for most construction machinery castings. Thanks to the innovative process where patterns vaporize during pouring, potential dimensional discrepancies that typically occur in traditional pattern drawing and core setting are entirely eliminated.
Surface Quality: Embrace the superior surface quality of our components, marked by an Ra value ranging from 6.3 to 12.5μm. The absence of parting surfaces on our castings significantly reduces common defects like flash and burrs, resulting in an extraordinary appearance quality. These components are ideally suited for visible parts or exposed elements of construction machinery where a flawless aesthetic is paramount.
Internal Quality: Our innovative casting process involves filling and solidifying the molten metal under negative pressure, enhancing both the density and overall quality of the castings. This method effectively minimizes common defects such as air holes and slag inclusions. Additionally, with the aid of the pattern, our process ensures that even castings with intricate structures, like those with internal cavities found in construction machinery, maintain impeccable shape and dimensional accuracy.
