Who we are
SND has been producing and selling metal goods for about 20 years.By using manufacturing techniques including sand casting, lost wax casting, lost foam casting, and precision machining, the company has been supplying goods made of materials like cast iron, steel, stainless steel, aluminum, etc. Additionally offered are surface finishing and assembly services.
Our company has successfully created products in a variety of industries, including automotive, rail transportation, agricultural machinery, chemical, energy, electricity, water, air compressor, and construction, thanks to our consistent efforts over the past few years.
Our factories' ISO9001-accredited quality control systems guarantee a consistent and dependable quality for each and every component.
Spectrometer, ultrasonic, magnetic, permeability, elongation, tensile/yield strength, and other inspections are carried out as part of routine production procedures.
Manufacturing Process
Material Preparation: High-quality pig iron and scrap iron are melted together, with magnesium added to create a ductile iron alloy.
Casting: The molten iron is poured into molds to form the basic shape of the manhole cover. Sand casting is a common method due to its precision and efficiency.
Heat Treatment: The cast pieces are treated with heat to improve strength and flexibility.
Surface Coating: Anti-corrosive coatings are applied to ensure longevity in various environments.
Quality Control: Each cover undergoes rigorous testing for load-bearing capacity, tensile strength, and dimensional accuracy
