Our Production

What is the most crucial aspect in wheels manufacturing? We see it as a mix of science and art. Combine it with continuous innovations and multistage quality check and you will get a product by YST Group.

Our production capacities entail 4 modern full-cycle plants: 2 alloy wheels plants with total output of 2 million units per year and 2 steel wheels plants producing 1.5 million units per year. Each plant meets all the requirements of ISO 14001:2004, ISO/TS 16949, ISO 9001:2008. All products have certificates of compliance TSE, CE.

Our wheels are designed and manufactured only by highly professional designers and engineers. Thanks to our recruitment system, we are always able to build a team of qualified best-in- class specialists and experts.

Virtual tests

We know everything about a wheel long before it is casted. Development of each model begins with a virtual mold simulation. Engineers design a 3D model and then take it through all types of virtual tests. Our software allows us to forecast, how a wheel will act on test benches. When a 3D model is approved, we produce a tryout batch, which is tested under real conditions.

Alloy wheels production

New model’s life cycle starts with mold casting. Our alloy and steel wheels are manufactured from raw materials of the highest quality from our trusted suppliers. Raw materials for steel wheels are supplied by Baosteel Group, worldwide renowned metallurgic giant.

Main alloy components are molten aluminum, silicon and alloying additives. In the process of production, we use aluminum cast alloy combined with T6 heat-treatment technology. It has the best heat-treatment resistance and 20% better resistance to mechanical impacts. When it’s ready, a tryout sample goes to spectral analysis to be checked for compliance with all regulations and standards.

Wheels are casted with 2 methods: low-pressure and gravity die casting. With our 25 7-axis automatic low-pressure casting stations and 20 gravity die casting machines, we ensure complete mold filling and tight alloy’s microstructure. Manufactured castings then undergo an X-ray check to exclude any internal defects.

Our highly accurate NC machines are able to cast and do the mechanical processing of any wheels sizes from 12 to 30 inches. We can also easily launch a required mold upon customer’s request.

Our paint lines installed at our plants are equipped with the cutting-edge equipment from Italy. In our production process, we use environment-friendly powder paints, which uniformly apply to wheel’s body improving the paintwork quality on even surfaces, sharp angles and edges. This method ensures high throwing power and absence of sagging, paint defects or orange peel.

Thanks to high covering power of powder paints, our wheels look great and resist to chemicals and mechanical impacts for years.

Steel wheels production

Steel wheels are manufactured from sheet metal supplied in coils. These coils are unrolled and cut separately for each wheel size. Each workpiece goes through roll-forging, pressing and welding to become a semi-finished product, which is then profiled and given the shape of a wheel’s rim.

At the assembly line, wheel spokes are pressed into the rim and welded with 4-stroke CO2 spot welding. A finished wheel is checked according to quality requirements and covered with protective and decorative coating.

Bench testing

Before they are released from production, wheels go through all kinds of quality checks on test benches in our own laboratory: test for tension, radial runout, dynamic balancing, tightness, corrosion resistance, structural integrity, micro cracks, chromatic control and paint adhesive properties.

YST Group guarantees its customers the unrivalled quality and stable consumer properties at 99.3% during the whole wheel’s lifetime of the wheel.
