Materials
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 provides manufacturing services for commercial vehicle parts, utilizing materials such as cast iron (sand casting), aluminum alloy (gravity casting, die-casting, investment casting, forging, and extrusion), as well as steel. In addition to forming, we also offer comprehensive machining processes including precision machining, surface treatment, assembly, and testing.
The transportation industry relies on commercial vehicles to fulfill tasks related to logistics and traffic transportation, with safety being a primary concern for most expectations. Components for commercial vehicles must adhere to strict tolerances to ensure smooth operation and minimize unnecessary wear and tear. In order to meet the requirements of commercial transportation, WKPT has developed CNC precision machining processes that meet the stringent tolerances and surface roughness required for components in the transportation industry. With machining capabilities of up to 1µm precision and surface roughness of Ra0.2µm, WKPT supplies the necessary components for the commercial vehicle sector.
In addition to safety, durability is also a concern for the commercial transportation industry, so commercial vehicle components need to meet durability expectations. Achieving greater durability for commercial vehicle components can be accomplished through heat treatment or surface treatment. Whether it's achieving better mechanical properties through heat treatment, increasing r ust resistance through coating treatments, or enhancing surface wear resistance through electroplating treatments, WKPT can provide added durability value to commercial vehicle components which are entrusted us for forming or machining.

The swash plate of the oil pump has strict requirements on the size, which is not able to be done by ordinary cutting centers. To meet the customer's drawing requirements, hardness enhanced by heat treatment, and grinding process are necessary in the process. Non-contact measurement will be used on partial holes to cover where three dimensional measurements can’t do.

Exhaust gas manifold, EGR (Exhaust Gas Recirculation) body, or automotive secondary intake manifold, secondary exhaust gas upper manifold. The partial product shape and size is shaped by gravity casting aluminum alloy. The aluminum alloy workpiece by gravity casting has stable quality. This makes castings with high precision dimensions and finer surface roughness, which can reduce the range of machining. The exhaust gas manifold is used to guide the exhaust gas back to the intake manifold, making it inhaled and burned by the engine again. Product properties should have high temperature resistance and vibration resistance. The dimension and shape tolerance is required to be below 15μm, and the surface roughness is required to be below Ra1.6.
