Lost Wax Casting
Dimensional Accuracy: The dimensional accuracy is relatively high, with the tolerance grade generally between CT6-CT9. The dimensional stability of the castings is good, which can meet the accuracy requirements of most castings for construction machinery. Since the pattern vaporizes and disappears during the pouring process, the dimensional errors that may occur during the pattern drawing and core setting processes are avoided.
Surface Quality: The surface quality is good, with the Ra value between 6.3-12.5μm. There is no parting surface on the surface of the castings, reducing defects such as flash and burrs, and the appearance quality is high. It has good applicability for some appearance parts or exposed components of construction machinery with high appearance requirements.
Internal Quality: The molten metal fills and solidifies under a negative pressure state, which is beneficial to improving the density and quality of the castings and reducing defects such as air holes and slag inclusions. At the same time, due to the presence of the pattern, for some castings with complex structures, such as the structural components of construction machinery with internal cavities, the shape and dimensional accuracy can be better ensured.

Transportation Precautions
Fixation and Protection:
During transportation, cast steel parts need to be fixed and protected to prevent them from moving and colliding inside the transport vehicle or cabin. For large cast steel parts, special fixing brackets and ropes may be required for fixation; for small cast steel parts, enough fillers also need to be added inside the packaging to ensure their stability during transportation.
Transportation Route Planning:
Before transportation, the transportation route needs to be planned, taking into account factors such as road conditions, bridge bearing capacity, and tunnel height to ensure the safe passage of the transport vehicle. For some large or overweight cast steel parts, it may be necessary to communicate with the road administration department in advance, apply for relevant transportation permits, and take necessary escort measures.
Transportation Insurance:
To reduce the risks during transportation, it is recommended to purchase transportation insurance for cast steel parts. When selecting transportation insurance, comprehensive consideration should be given according to factors such as the value of the goods, transportation mode, and transportation route to select a suitable insurance plan.
Loading and Unloading Requirements:
When loading and unloading cast steel parts, appropriate loading and unloading equipment, such as forklifts and cranes, should be used, and the operation should be carried out by professional operators. During the loading and unloading process, care should be taken to avoid collisions and damage to the cast steel parts, and at the same time, the safety and stability of the loading and unloading equipment should be ensured.
Packaging Forms
Wooden Box Packaging:
Suitable for cast steel parts of various sizes and weights, especially large cast steel parts. Wooden boxes have good compressive and protective properties, which can prevent cast steel parts from being squeezed and collided during transportation. When packaging, the cast steel parts are first wrapped with plastic film or oil paper, and then placed in the wooden box. Wooden wedges or foam materials are used for fixation to prevent them from shaking inside the wooden box.
Carton Packaging:
For some small cast steel parts, carton packaging can be used. Carton packaging is lightweight and cost-effective, but attention needs to be paid to the strength and moisture resistance of the carton. When packaging, the cast steel parts are usually first wrapped with plastic bags or bubble bags, and then placed in the carton. Fillers are used to fill the carton to prevent the cast steel parts from moving inside.
Pallet Packaging:
For mass-produced cast steel parts, pallet packaging is often adopted. The cast steel parts are neatly stacked on the pallet, and then fixed with stretch film or strapping tape, which is convenient for handling and transportation by forklifts. This packaging method is suitable for some cast steel parts with relatively uniform specifications in the agricultural machinery and construction machinery industries.
