Innovative Lost Wax Casting Technique
Dimensional Accuracy: Our castings boast exceptional dimensional accuracy, typically falling within the CT6-CT9 tolerance grade range. This precision ensures incredible dimensional stability, meeting and often exceeding the rigorous accuracy demands of construction machinery castings. The innovative process allows for the pattern to vaporize and disappear during pouring, skillfully eliminating potential errors that could arise from traditional pattern drawing and core setting methods.
Surface Quality: The surface quality of our castings is nothing short of outstanding, featuring an Ra value range of 6.3-12.5μm. The absence of a parting surface results in a marked reduction of defects such as flash and burrs, ensuring a superior aesthetic appearance. These qualities make it exceptionally well-suited for application in construction machinery components where aesthetic appeal and surface integrity are paramount.
Internal Quality: Our sophisticated casting process involves the molten metal filling and solidifying under a negative pressure environment. This enhances the density and overall quality of the castings by significantly reducing common defects like air holes and slag inclusions. Moreover, the presence of the pattern proves advantageous for complex structures, particularly those in construction machinery with intricate internal cavities, guaranteeing excellent shape and dimensional accuracy.

Transportation Precautions
Fixation and Protection:
During the transportation of our premium cast steel parts, it is paramount to ensure they are securely fixed and safeguarded to prevent any movement or collisions within the transport vehicle or cabin. Large cast steel parts may require specialized fixing brackets and ropes for added stability; while smaller parts benefit from ample filler material within packaging to maintain their steadiness throughout the journey.
Transportation Route Planning:
Proactive transportation route planning is essential. Assess road conditions, bridge load capacities, and tunnel heights to guarantee the seamless transit of our transport vehicles. For oversized or heavy cast steel parts, liaise with road authorities in advance to obtain necessary transportation permits and organize tailored escort measures for safe passage.
Transportation Insurance:
To mitigate transportation risks, securing insurance for cast steel parts is highly advisable. When choosing the right insurance plan, consider the value of the goods, the mode of transportation, and the route. This allows you to select an insurance plan that offers ideal coverage and peace of mind throughout the transportation process.
Loading and Unloading Requirements:
Ensure skilled professionals handle the loading and unloading of our cast steel parts using appropriate equipment, such as forklifts and cranes. Prioritize meticulous execution to avoid impact or damage. It's vital to maintain the safety and operational stability of both the cast steel parts and the equipment used.
Packaging Forms
Wooden Box Packaging:
Ideal for cast steel parts of varying sizes and weights, especially larger components. Wooden boxes offer excellent compressive strength and protective qualities, safeguarding cast steel parts from pressure and collision during transit. Begin by wrapping parts in plastic film or oil paper, then secure them in wooden boxes with wedges or foam to eliminate internal shifting.
Carton Packaging:
For smaller cast steel parts, carton packaging is a lightweight and cost-effective alternative. Ensure the carton’s durability and resistance to moisture. Begin by wrapping parts in plastic or bubble bags, and use fillers to maintain stability and prevent movement within the carton.
Pallet Packaging:
Mass-produced cast steel parts often utilize pallet packaging. Stack parts neatly on the pallet, securing them with stretch film or strapping tape for easy handling and transport via forklift. This method suits parts with uniform specifications commonly found in agriculture and construction machinery sectors.
