Innovative Lost Wax Casting Technique: Our state-of-the-art Lost Wax Casting process ensures precision and excellence. This traditional technique is elevated with modern technology, guaranteeing exceptional results that meet the rigorous demands of today's engineering challenges.
Dimensional Precision Expertise: Our castings boast exceptional dimensional accuracy, with tolerance grades typically ranging between CT6-CT9. This high level of precision ensures that our products meet the stringent accuracy demands of most construction machinery castings. The vaporization and disappearance of the pattern during pouring virtually eliminate the potential for dimensional errors that could arise in the pattern drawing and core setting stages.
Exquisite Surface Quality: Revel in the superb surface quality of our cast steel accessories, with an Ra value between 6.3-12.5μm. Free from parting surfaces, our castings minimize defects such as flash and burrs, ensuring a high-quality appearance. This makes them exceptionally suitable for visible parts or exposed components of construction machinery where aesthetics are paramount.
Unmatched Internal Quality: Our casting process, carried out under negative pressure, significantly enhances the density and quality of the final product, effectively minimizing defects like air holes and slag inclusions. Additionally, the use of patterns facilitates maintaining precise shape and dimensional accuracy for complex structures, including construction machinery components with internal cavities.

Transportation Precautions
Fixation and Protection:
During transportation, it is imperative that our robust cast steel parts receive meticulous fixation and protection to avert any movement or collision within the transport vehicle or cabin. For larger components, the employment of specialized securing brackets and ropes is essential, whereas smaller parts should be cushioned with adequate fillers inside their packaging to maintain unwavering stability throughout their journey.
Transportation Route Planning:
Prior to embarking on transportation, a comprehensive planning of the route is crucial, considering factors such as road conditions, bridge load capacities, and tunnel heights to ensure seamless and safe transit of the vehicle. In the case of particularly large or heavy-duty cast steel components, prior coordination with road authorities is recommended to procure necessary transportation permits and to arrange for any required escort services.
Transportation Insurance:
To mitigate transportation risks, it is advisable to secure transportation insurance for our esteemed cast steel parts. A judicious selection of an insurance plan should be based on a thorough evaluation of factors like the value of the items, mode of transport, and chosen route, ensuring you opt for the most appropriate insurance coverage.
Loading and Unloading Requirements:
The loading and unloading of cast steel parts necessitate the use of suitable equipment such as forklifts and cranes, operated by skilled professionals. It is vital to execute these operations with utmost care to prevent any collisions or damage, while concurrently ensuring the operational safety and stability of the loading and unloading machinery.
Packaging Forms
Wooden Box Packaging:
This packaging is ideal for cast steel parts of varying sizes and weights, especially the larger ones. Wooden boxes offer superb compressive strength and protection, safeguarding the parts from pressure and contact during transit. The procedure involves initially encasing the parts with plastic film or oil paper, positioning them in the wooden box, and securing them with wooden wedges or foam to avert any internal movement.
Carton Packaging:
For smaller cast steel components, carton packaging is a pragmatic option. Lightweight and economical, carton packaging demands attention to the durability and moisture resistance of the materials. The process involves wrapping the parts in plastic or bubble bags, placing them within the carton, and adding fillers to restrain any internal movement.
Pallet Packaging:
Mass-produced cast steel parts are typically packaged on pallets, allowing for orderly stacking and fastening with stretch film or strapping tape. This method facilitates efficient handling and transport via forklifts, and is particularly beneficial for parts with consistent specifications in industries like agricultural and construction machinery.
