Sophisticated Lost Wax Casting Process
Dimensional Accuracy: Experience superior dimensional precision with tolerance grades typically ranging between CT6-CT9. Our castings boast exceptional dimensional stability, perfectly aligning with the accuracy demands of most construction machinery applications. As the pattern vaporizes and vanishes during the pouring process, any potential dimensional errors from pattern drawing and core setting are effectively eliminated.
Surface Quality: Revel in exceptional surface quality, with Ra values ranging from 6.3-12.5μm. The absence of parting surfaces on the castings minimizes defects such as flash and burrs, resulting in outstanding appearance quality. Our products are ideally suited for appearance parts or exposed components of construction machinery that demand superior aesthetic standards.
Internal Quality: Our innovative process ensures molten metal fills and solidifies under negative pressure, significantly enhancing the density and integrity of the castings while minimizing defects like air holes and slag inclusions. Additionally, the presence of the pattern allows for superior shape and dimensional accuracy, particularly for castings with intricate structures, such as the structural components of construction machinery featuring internal cavities.

Transportation Precautions
Fixation and Protection:
During transportation, it is essential to ensure that our precision cast high-performance carbon steel parts are securely anchored and shielded to prevent unwanted movement and potential collisions within the transport vehicle or cabin. For our larger cast steel components, specialized brackets and sturdy ropes become imperative; while for the smaller ones, ample cushioning within the packaging is crucial to maintain stability throughout the journey.
Transportation Route Planning:
Meticulous route planning is crucial prior to transportation, considering all pivotal elements like road conditions, bridge load limits, and tunnel clearances to assure the undisturbed passage of our transport vehicles. For particularly sizable or heavy cast steel elements, it may be necessary to coordinate with road authorities beforehand, secure requisite transportation permits, and arrange for necessary escort protocols.
Transportation Insurance:
Mitigate potential transportation risks by investing in a robust transportation insurance policy for our cast steel components. Carefully evaluate the insurance options based on cargo value, chosen transport mode, and planned route to select a well-suited coverage plan that ensures peace of mind throughout the shipping process.
Loading and Unloading Requirements:
The process of loading and unloading our cast steel parts demands the use of appropriate machinery such as forklifts and cranes, handled exclusively by skilled operators. It's imperative to prevent any impact or damage to the cast steel components, while also guaranteeing the operational safety and stability of the equipment employed.
Packaging Forms
Wooden Box Packaging:
Wooden box packaging serves as an ideal solution for cast steel parts of diverse dimensions and weights, notably larger ones. These boxes offer remarkable compression resistance and protective qualities, safeguarding the components against pressure and collisions en route. The packaging process involves initially enveloping the cast steel parts in plastic film or oil paper, followed by their secure placement in the wooden box, using wooden wedges or foam for stabilization.
Carton Packaging:
For smaller cast steel parts, carton packaging emerges as a lightweight and economical choice. However, attention must be paid to the carton’s durability and moisture resistance. The procedure entails initially wrapping the parts in protective plastic or bubble wrap, then placing them inside the carton, utilizing filler materials to restrict any internal movement.
Pallet Packaging:
Mass-produced cast steel parts are often best accommodated with pallet packaging. The components are methodically arranged on the pallet and secured with stretch film or strapping tape, facilitating easy handling and transport via forklifts. This method is especially advantageous for uniform cast steel parts utilized in the agricultural and construction machinery sectors.
