Lost Wax Casting: Experience the pinnacle of casting excellence with our advanced Lost Wax Casting technique. It ensures superior precision and an unparalleled finish, essential for intricate designs and high-performance applications.
Dimensional Accuracy: Our products boast exceptional dimensional accuracy, maintaining a tolerance grade typically between CT6-CT9. The stability of these castings is remarkable, ensuring they meet the stringent accuracy standards required for construction machinery. As the pattern vaporizes during the pouring process, this innovative approach eliminates potential errors from pattern drawing and core setting, offering unparalleled precision.
Surface Quality: Our castings exhibit exceptional surface quality, with an Ra value ranging from 6.3-12.5μm. The absence of parting surfaces minimizes defects such as flash and burrs, delivering an impeccable appearance. This high-quality finish is ideal for components with stringent aesthetic requirements, ensuring your construction machinery boasts both functionality and visual appeal.
Internal Quality: Our casting process harnesses negative pressure to enhance the density and quality of our products, significantly reducing imperfections like air holes and slag inclusions. The use of patterns in our methodology proves advantageous for complex structures, ensuring precise shapes and dimensions, particularly for intricate construction machinery components with internal cavities.

Transportation Precautions
Fixation and Protection:
In the realm of transportation, safeguarding your valuable cast steel parts is paramount. To ensure they remain secure and immobile during transit, it's essential to employ robust fixation and protection measures. For large cast steel parts, this might involve using specialized fixing brackets and sturdy ropes. Meanwhile, smaller parts benefit from ample padding within their packaging, ensuring their stability and preventing any unwanted movement or collisions within the transport vehicle or cabin.
Transportation Route Planning:
Meticulous planning of the transportation route is crucial before embarking on your journey. Consider road conditions, bridge load capacities, and tunnel heights to guarantee the safe passage of your transport vehicle. In cases involving large or particularly heavy cast steel parts, proactive communication with road administration authorities is recommended. By obtaining necessary transportation permits and organizing escorts if required, you ensure a smooth and secure delivery process.
Transportation Insurance:
Mitigate transportation risks by opting for comprehensive insurance coverage for your cast steel parts. When selecting a transportation insurance plan, factor in the value of your goods, the chosen mode of transport, and the planned route. By doing so, you can select an insurance plan that aligns perfectly with your needs, ensuring peace of mind and financial protection throughout the journey.
Loading and Unloading Requirements:
The loading and unloading of cast steel parts demand precision and care. Utilize appropriate equipment like forklifts and cranes, operated by skilled professionals, to handle these components. The focus should be on avoiding any collisions or damage to the cast steel parts during this process. Ensuring the stability and safety of the equipment used is equally vital, safeguarding both the operator and the valuable cargo.
Packaging Forms
Wooden Box Packaging:
Wooden box packaging stands as a stalwart choice for securing cast steel parts of varying sizes and weights, especially larger components. These boxes offer excellent compressive strength and protection, effectively preventing any squeezing or collision during transit. The packaging process begins by wrapping the cast steel parts in plastic film or oil paper, followed by secure placement within the box. Wooden wedges or foam materials further stabilize the parts, eliminating any potential shaking inside the box.
Carton Packaging:
For smaller cast steel components, carton packaging emerges as a lightweight and economical option. To maximize its effectiveness, ensure the cartons possess adequate strength and moisture resistance. Begin by encasing the cast steel parts in plastic or bubble bags, then position them within the carton. Utilize fillers to occupy any empty spaces, preventing movement and maintaining the integrity of the parts during transit.
Pallet Packaging:
In the realm of mass production, pallet packaging is the go-to choice for cast steel parts. This method involves neatly stacking parts on pallets, securing them with stretch film or strapping tape. This technique facilitates easy handling and efficient transportation with forklifts. Pallet packaging is especially suitable for cast steel parts with uniform specifications, often found in the agricultural and construction machinery sectors.
