Whether it's onshore or offshore wind turbine, in response to extreme weather and marine conditions, WKPT's manufacturing capabilities enable the production of parts resistant to temperatures as low as -20°C. From forming, design to machining processes, we can meet all machining requirements of end customers.


In response to severe marine conditions, WKPT can provide ductile iron materials with superior low-temperature impact resistance compared to EN-GJS-LT, and continuously research the impact toughness of ductile iron for conditions ranging from -40°C to -60°C. The benefit of outsourcing wind turbine components to WKPT is that even corrosion protection coatings of ISO12944 C3M/C4H standards can be seamlessly handled along with it.


WKPT is certified through ISO 9001:2015 and IATF 16949. Parts produced through international quality management systems have passed quality assurance, which also contributes to the safety and lifespan of wind turbine equipment.

Environmental Protection

WKPT recognizes the importance of developing green and low-carbon energy sources. Therefore, we are committed to providing manufacturing services for wind energy equipment components, assisting in the localization of wind energy parts production. WKPT has also implemented the ISO 14001 environmental management system, demonstrating its commitment to environmental protection by reducing resource waste through the reduction of material and energy consumption.


We have experienced sales personnel proficient in English and Japanese who can provide you with end-to-end services from the design to the delivery of wind energy components. In addition to core manufacturing services for precision components, we also offer related post-processing services to streamline your procurement process.

Machining Cases


    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.

    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.

    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.

    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).

    Manufacturing Capabilities

    WKPT uses cast iron, steel, and aluminum alloys as materials to provide various types and specifications of wind energy equipment parts manufacturing. We have one-stop machining services such as forming, finishing, precision machining, surface treatment, assembly, and testing.

    Machining is the main business of WKPT. We use high-toughness ductile iron as the material and undergo machining processes such as cutting to manufacture wind energy equipment parts.

    In the post-processing stages of wind energy equipment components, WKPT offers surface treatment services such as liquid coating, powder coating, anodizing, and hard anodizing. Our facility is equipped with liquid coating facilities, suspended conveyor systems, and wastewater treatment systems to enhance the wear resistance and corrosion resistance of wind energy equipment components.

      WKPT is the only one supplier of wind turbine brake cylinders in Taiwan. The material selection of wind turbine components is rather strict; the wind turbine brake system is made of ductile iron material with better low temperature impact resistance than EN-GJS-LT, which can still work even at temperatures far below 0°C. In addition, the workpiece is heavy so it needs to be processed by large-scale machining equipment. The size requirement of workpiece is strict and has long and deep holes, so it needs to be machined with special tools.
