Lost Wax Casting - A Timeless Craft: Immerse yourself in the timeless art of Lost Wax Casting. This traditional technique, renowned for its precision and versatility, ensures each piece is molded to perfection, meeting the bespoke needs of construction machinery.
Dimensional Accuracy - Precision Redefined: Our precision cast carbon steel parts boast remarkable dimensional accuracy, with tolerance grades ranging between CT6-CT9. This ensures exceptional stability and fidelity, meeting the stringent standards required for construction machinery components. The vaporization of patterns during pouring eliminates errors from pattern drawing and core setting, guaranteeing unmatched accuracy and excellence in every component.
Surface Quality - Flawless Finish: Revel in the superior surface quality of our castings, with an Ra value ranging from 6.3-12.5μm. The absence of parting surfaces enhances the aesthetic appeal, minimizing defects like flash and burrs. Perfect for components where visual appeal is paramount, these parts are ideal for exposed machinery elements that demand top-notch appearance standards.
Internal Quality - Excellence from Within: Our castings are crafted under negative pressure, optimizing the density and integrity of each piece. This method significantly reduces defects like air pockets and slag inclusions. Even in intricate castings with complex cavities, our process ensures precision in shape and dimension, making them ideal for the demanding structural components of construction machinery.

Transportation Precautions
Fixation and Protection:
To ensure the utmost safety during transit, it is crucial that cast steel parts are securely fixed and adequately protected, preventing any unwarranted movement or collision within the transport vehicle or cabin. Large cast steel components may necessitate the use of specially designed brackets and robust ropes for secure fixation. In contrast, smaller cast steel parts should be cushioned with ample fillers within their packaging, ensuring stability throughout their journey.
Transportation Route Planning:
Meticulous planning of the transportation route is imperative before embarking on the journey, considering critical elements such as road conditions, bridge load capacities, and tunnel heights to guarantee the seamless passage of the transport vehicle. For oversized or heavy cast steel parts, proactive communication with the road administration may be required. Acquire necessary transportation permits and coordinate essential escort measures to ensure a smooth and safe transit.
Transportation Insurance:
To mitigate any potential risks associated with the transportation of cast steel parts, procuring transportation insurance is strongly advised. When selecting this insurance, a comprehensive analysis based on factors such as the cargo's value, chosen transportation mode, and specific route should be conducted to determine the most suitable insurance plan, providing peace of mind throughout the journey.
Loading and Unloading Requirements:
The loading and unloading of cast steel parts demand the use of appropriate equipment, including forklifts and cranes, operated exclusively by skilled professionals. During these processes, it is paramount to prevent any potential collisions or damage to the cast steel parts while simultaneously ensuring the safety and stability of the equipment involved.
Packaging Forms
Wooden Box Packaging:
This packaging method is ideal for cast steel parts across a spectrum of sizes and weights, particularly for large components. Wooden boxes offer excellent compression resistance and protective properties, safeguarding the cast steel parts from compression and impact during transportation. Initially, the parts are wrapped in protective plastic film or oil paper, then securely placed in the wooden box. Wooden wedges or foam materials are utilized for firm fixation, preventing any internal movement within the box.
Carton Packaging:
Carton packaging presents a lightweight and cost-effective solution for smaller cast steel parts. However, attention must be paid to the carton’s strength and moisture resistance. Prior to packaging, the parts are wrapped in plastic or bubble bags and placed within the carton. Fillers are strategically added to prevent any internal shifting, maintaining the integrity of the parts during transit.
Pallet Packaging:
Pallet packaging is a favored choice for mass-produced cast steel parts. These parts are meticulously arranged on a pallet, then secured using stretch film or strapping tape, facilitating easy handling and transportation by forklifts. This method is particularly advantageous for cast steel parts in the agricultural and construction machinery sectors, where uniform specifications are prevalent.
