Lost Wax Casting: Discover the ancient art of Lost Wax Casting, expertly employed to create our high-caliber steel parts. This time-honored technique ensures precision and durability, providing the ideal foundation for our customizable cast steel components that enhance machinery efficiency.
Dimensional Accuracy: Our cast steel parts boast outstanding dimensional accuracy, typically maintaining tolerance grades between CT6 to CT9. This ensures remarkable dimensional stability, perfectly aligning with the stringent accuracy demands of construction machinery. By eliminating dimensional errors associated with pattern drawing and core setting, we ensure that each component meets exacting specifications with unparalleled precision.
Surface Quality: Experience unmatched surface quality with our cast steel parts, featuring Ra values ranging from 6.3 to 12.5μm. The absence of a parting surface minimizes defects like flash and burrs, resulting in superior appearance quality. Ideal for components that require impeccable aesthetics, our castings are perfect for exposed parts of construction machinery where high visual standards are essential.
Internal Quality: Our casting process utilizes a negative pressure environment to enhance the density and integrity of each component, significantly reducing common defects such as air holes and slag inclusions. This method, complemented by pattern presence, ensures precise shape and dimensional accuracy in complex structural components, particularly those with internal cavities, crucial for construction machinery's intricate parts.

Transportation Precautions
Fixation and Protection:
During the crucial journey of transportation, it is vital to secure and shield our high-performance cast steel parts to prevent any movement or collision within the vehicle or cabin. For our large cast steel marvels, specialized brackets and robust ropes ensure steadfast fixation, while for the smaller parts, ample fillers within the packaging play a pivotal role in maintaining their stability throughout the journey.
Transportation Route Planning:
Before embarking on transportation, meticulous route planning is essential. Considerations such as road conditions, bridge load capacities, and tunnel heights are paramount to guarantee the safe passage of the transport vehicle. For exceptionally large or heavy cast steel parts, early communication with road authorities and securing necessary transportation permits is prudent, along with implementing escort measures to ensure a seamless journey.
Transportation Insurance:
To safeguard against potential risks during transit, it is highly advisable to procure transportation insurance for our cast steel parts. When selecting transportation insurance, factors like the product's value, chosen mode of transport, and the planned route should be thoroughly evaluated to craft the perfect insurance plan that meets all needs and contingencies.
Loading and Unloading Requirements:
In the realm of loading and unloading our prized cast steel parts, it is imperative to utilize appropriate equipment such as forklifts and cranes operated by experienced professionals. During these operations, meticulous care must be taken to prevent any mishaps or damage to the cast steel parts, all while ensuring the safety and unwavering stability of the loading and unloading equipment.
Packaging Forms
Wooden Box Packaging:
An exceptional choice for cast steel parts of varying sizes and weights, especially the larger ones. Wooden boxes offer remarkable compressive strength and protection, effectively safeguarding against squeezing and collisions during transport. Initially, the cast steel parts are wrapped with protective plastic film or oil paper, then securely placed inside the wooden box. To further ensure stability, wooden wedges or foam materials are employed, effectively preventing any movement within.
Carton Packaging:
Ideal for our smaller cast steel components, carton packaging stands out as lightweight and economically viable. However, attention to the carton’s strength and moisture resistance is crucial. Each piece is meticulously wrapped in protective plastic or bubble bags before being placed into the carton. Strategic fillers are used to ensure the cast steel parts remain immobile within, securing their safety and integrity.
Pallet Packaging:
For mass-produced cast steel parts, pallet packaging is a preferred method. The parts are precisely stacked on a pallet and secured with stretch film or strapping tape, facilitating effortless handling and transportation via forklifts. This method is particularly suitable for uniform specifications found in agricultural and construction machinery industries, ensuring efficiency and effectiveness.
