Lost Wax Casting
Dimensional Accuracy: Experience unparalleled precision with our High-Performance Precision Cast Steel Components, boasting exceptional dimensional accuracy. Our products maintain an impressive tolerance grade, ranging between CT6-CT9, ensuring exceptional dimensional stability. This remarkable precision meets the stringent accuracy demands of construction machinery. By using a pattern that vaporizes during the pouring process, we eliminate potential dimensional errors often encountered during pattern drawing and core setting, guaranteeing superior performance.
Surface Quality: Revel in the exceptional surface finish of our castings, exhibiting a remarkable Ra value between 6.3-12.5μm. Our castings are free of parting surfaces, minimizing the risk of defects such as flash and burrs, and ensuring a superior appearance quality. These components are perfectly suited for appearance parts or exposed components in construction machinery, where high aesthetic standards are required.
Internal Quality: Our casting process ensures superior internal quality by solidifying the molten metal under a negative pressure state. This technique significantly enhances the density and integrity of the castings, effectively minimizing defects like air holes and slag inclusions. The presence of a pattern allows for precise shape and dimensional accuracy, particularly beneficial for complex structural components of construction machinery featuring internal cavities, thus ensuring high-quality performance and reliability.

Transportation Precautions
Fixation and Protection:
During transportation, it is of utmost importance to securely fix and protect the cast steel parts to prevent any movement or collision within the transport vehicle or cabin. For larger cast steel components, specialized fixing brackets and ropes may be employed, while smaller parts require ample fillers within their packaging to ensure stability throughout the journey.
Transportation Route Planning:
Prior to embarking on transportation, a meticulous route plan should be devised, incorporating crucial elements such as road conditions, bridge load capacity, and tunnel height. These steps are vital to guarantee smooth and secure passage of the transport vehicle. For particularly large or overweight cast steel parts, proactive communication with road authorities is essential to obtain necessary permits and implement any required escort measures.
Transportation Insurance:
To mitigate potential risks during transit, securing transportation insurance for cast steel parts is highly advised. When selecting an insurance plan, it is crucial to comprehensively evaluate the value of the goods, the mode of transportation, and the chosen route to ensure the most appropriate and protective coverage.
Loading and Unloading Requirements:
The loading and unloading of cast steel parts should be conducted using suitable equipment, such as forklifts and cranes, operated by skilled professionals. It is imperative to exercise caution to avoid any collisions or damage, and to ensure the stability and safety of both the equipment and the cast steel parts throughout the process.
Packaging Forms
Wooden Box Packaging:
Ideal for cast steel parts of varying sizes and weights, particularly larger ones, wooden boxes offer superior compressive strength and protection. By preventing any squeezing or collision during transit, this packaging style ensures the utmost safety. Initially, parts are wrapped in plastic film or oil paper, then placed in wooden boxes. To further stabilize them, wooden wedges or foam materials are used to prevent any movement within the box.
Carton Packaging:
For smaller cast steel components, carton packaging is a lightweight and cost-effective solution. However, attention must be given to the carton's strength and moisture resistance. Typically, parts are wrapped in plastic or bubble bags, then nestled in the carton with fillers, ensuring they remain immobile during transit.
Pallet Packaging:
In scenarios of mass production, pallet packaging is often favored. Cast steel parts are neatly arrayed on pallets, then secured with stretch film or strapping tape. This approach facilitates easy handling and transportation via forklifts, making it an ideal choice for cast steel parts with uniform specifications, especially in the agricultural and construction machinery sectors.
