Precision Lost Wax Casting: A Revolutionary Technique
Dimensional Accuracy: Our product boasts superior dimensional accuracy, with tolerance grades ranging between CT6-CT9. This ensures exceptional dimensional stability, meeting the stringent precision requirements for a wide array of construction machinery castings. The innovative production process eliminates the need for pattern drawing and core setting, thereby minimizing potential dimensional errors.
Surface Quality: Experience unmatched surface quality with our products, featuring an Ra value between 6.3-12.5μm. The absence of parting surfaces significantly reduces the occurrence of defects such as flash and burrs, resulting in a high-quality appearance. This makes our castings ideal for construction machinery parts that demand superior surface aesthetics and durability.
Internal Quality: Produced under negative pressure, our castings achieve remarkable density and quality, effectively minimizing defects like air holes and slag inclusions. Even for complex structural components with internal cavities in construction machinery, the presence of the pattern ensures precise shape and dimensional accuracy, setting a new standard in quality and reliability.

Transportation Precautions
Fixation and Protection:
To ensure the safe journey of our cast steel parts, it is imperative to secure them properly during transportation. Whether large or small, each piece needs to be fixed and cushioned to prevent any movement or collisions inside the vehicle. For substantial components, specialized brackets and ropes are essential, while smaller items demand ample filler materials within their packaging to guarantee stability throughout their voyage.
Transportation Route Planning:
Meticulous planning of transportation routes is crucial for safety, factoring in road conditions, bridge capacities, and tunnel heights. For oversized or heavyweight cast steel parts, it is vital to liaise with road authorities, obtain necessary permits, and arrange for escorts to ensure a smooth and secure transit.
Transportation Insurance:
To mitigate transportation risks, securing an appropriate insurance policy for cast steel parts is highly recommended. Consider the value of the cargo, the chosen transportation method, and the route specifics when selecting an insurance plan that provides comprehensive coverage and peace of mind.
Loading and Unloading Requirements:
Professional handling of cast steel parts during loading and unloading is crucial. Employ suitable equipment, such as forklifts and cranes, operated by qualified personnel. This ensures the integrity of the parts and the safety of the equipment, preventing collisions and potential damage throughout the process.
Packaging Forms
Wooden Box Packaging:
Perfectly suited for cast steel parts of all dimensions, especially the larger ones, wooden box packaging offers superior compression resistance and protection. This method involves wrapping parts with plastic film or oil paper before securing them in wooden boxes with wedges or foam, effectively preventing internal movement and ensuring a secure transit.
Carton Packaging:
Ideal for smaller cast steel parts, carton packaging is economical and lightweight, but requires attention to strength and moisture resistance. Parts are placed in cartons after being wrapped in plastic or bubble wrap, with fillers added to immobilize them, ensuring safe and cost-effective transportation.
Pallet Packaging:
For cast steel parts produced in large quantities, pallet packaging is the go-to solution. Parts are methodically stacked and secured with stretch film or strapping tape, facilitating easy handling and transport via forklifts. This method is especially suited for uniform-sized parts in agricultural and construction machinery sectors.
