Construction Machinery Parts Manufacturer

Why Choose WKPT for Construction Industry?

Manufacturing components for the next generation of construction machinery requires consideration of engine air pollution emissions while simultaneously improving hydraulic system efficiency to achieve shock absorption and noise reduction effects.

Construction machinery needs to reduce fuel consumption of petrochemical fuels during operation and improve energy conversion efficiency. The next generation of construction machinery and components should focus on reducing engine air pollutant emissions in their design and manufacturing, aiming to improve hydraulic system efficiency, shock absorption, and noise reduction. WKPT integrates its supply chain, providing optimized processing technology for materials such as cast iron, aluminum alloy, stainless steel, and carbon steel. We offer a one-stop machining service for custom construction equipment spare parts, including excavator spare parts, dozer spare parts, and truck spare parts, ensuring top-quality heavy machinery spare parts for your needs.

Materials

Cast iron materials refer to iron-carbon alloys with carbon content more than 2.11%. In addition to carbon, there are also elements such as silicon, manganese, and a small amount of sulfur and phosphorus. Cast iron is usually made of pig iron, scrap steel, ferroalloys, etc. in different proportions through smelting.

Cast Iron

Aluminum alloy is the general term for aluminum-based alloys. The main alloy elements are copper, silicon, magnesium, zinc, and manganese, and the secondary alloy elements are nickel, iron, titanium, and chromium.

Aluminum Alloy

Stainless steel, also known as galvanized iron, is the common name for corrosion-resistant steel. More specifically, steel with chromium (Cr) content greater than 12% in molten steel is called stainless steel.

Stainless Steel

Carbon steel is an iron alloy with carbon elements, that is, iron-carbon alloy. Carbon steel refers to carbon content higher than 0.02% and lower than 2% (above 2% is called cast iron, and less than 0.02% is called wrought iron).

Carbon Steel

Copper alloy is the general term for copper-based alloys, mainly created by combining copper with elements such as zinc, tin, nickel, and aluminum. It features excellent electrical and thermal conductivity, high corrosion resistance, superior machinability, and non-magnetic properties.
