The sunshade head is made using silica sol precision casting, primarily because it perfectly matches the triple requirements of this type of hardware: surface quality, dimensional accuracy, and complex structure.

Extremely High Surface Finish, Ideal for Subsequent Sandblasting:

The silica sol mold shell is dense and heat-resistant, resulting in a stainless steel head with good surface roughness, virtually free of adhering sand and inclusions. This perfectly matches the ideal substrate condition for glass bead sandblasting—creating a fine and uniform matte finish after sandblasting, avoiding localized reflections or uneven coating adhesion caused by numerous pits in the original casting, directly enhancing the product's texture.

High Dimensional Accuracy, Ensuring Assembly of the Transmission Structure:

Silica sol precision castings offer dimensional stability and minimal seam allowance. This ensures smooth assembly of the head with the sunshade shaft, springs, and other components, preventing jamming and abnormal noise during repeated pulling, and reducing the cost of subsequent CNC finishing.

Suitable for Complex Thin-Wall One-Piece Molding, Balancing Strength:

The good fluidity of the silica sol slurry allows for clear replication of the fine structure of the wax model, enabling the one-piece casting of thin-walled heads with internal cavities. Stainless steel offers high corrosion resistance while maintaining wear resistance and strength under high-frequency torsion.

It boasts excellent material adaptability and is clean and environmentally friendly：

Modern silica sol technology further enhances environmental friendliness, aligning with the quality control trends of high-end building materials and home hardware.
