Uzer Makina is a leading tyre technology provider serving top tyre makers worldwide with its tyre curing presses and moulds since 1978. Uzer Makina’s press product category consists of mechanical and hydraulic presses for all kinds of tyres, while the mould category includes tread segments, sidewall plates, container mechanisms, AG moulds and bladder moulds.
Uzer Makina recently announced the commencement of its brand-new casting foundry to produce casting tread segment moulds in-house. This used to be a process that was being outsourced in the past. However, after a long research period that took approximately three years, Uzer Makina finally developed and started its own casting methodology.
Uzer Makina has always been a company that is an expert at utilising milling technology with its state-of-the-art machines. Therefore, the primary method for producing segmented moulds has always been the engraving method. The engraving method has many advantages, such as being much more precise than casting and cost-effective while manufacturing a few moulds from a pattern/size. This precision is often required for ultra-high-performance PCR tyres to reach desired uniformity levels. However, casting methodology is obviously the better option when producing moulds with high complexity (e.g. PCR winter tyre moulds) and when a high amount of moulds from one pattern/size are requested.
The casting process of moulds is a bit complicated compared to the direct engraving method. First, CAD data is used to produce a model. The model is obtained by utilising 5-axis machines. Then, the model sipes need to be inserted into this model. After this process, a silicone mixture should be poured into the model to obtain a silicone mould, which is the doublet of the real segmented mould. Later, casting sipes should be inserted on this silicone mould and plaster mixture is poured into the silicone mould to obtain the plaster model. In this process, casting sipes should transfer to the plaster model. The final step is to make the aluminium casting. The aluminium alloy should be melted and poured into the plaster model to get the final product.
One of the most critical steps to be an expert in aluminium tyre mould casting is to manufacture all types of tyre mould sipes used on the moulds. While developing an in-house casting project, in the meantime, Uzer Makina also started its own sipe production line, which once used to be a process outsourced as it was for casting segments. More than 100 types of sipes are being produced in-house, and research and development activities continue to diversify sipe types, including regular 3D sipes and 3D-printed sipes.
Yokohama Rubber has established a new research and development centre in Hangzhou, China, as the Japanese tyre maker seeks to strengthen localised product development and speed up response times in the Chinese market.
The new facility, named Yokohama China Technical Center, began operations in May within the company’s new passenger car tyre plant in Hangzhou, which started production in November 2025.
The company said the centre would enable the local development of products specifically for the Chinese market, from initial research through to completion, helping to accelerate product launches and improve responsiveness to regional demand.
The centre will consolidate R&D functions for Yokohama Rubber’s tyre and multiple business divisions in China, while expanding engineering staff and testing facilities. Its activities will include tyre development, raw material analysis and evaluation, supplier audits, and mould drawing preparation.
Yokohama Rubber said the new operation would also support research into new raw materials and the development of local suppliers in China.
The company currently operates tyre plants in Hangzhou and Suzhou, alongside multiple business plants in Hangzhou and Weifang.

The system is intended to integrate with driving systems to provide functionalities for mobility and safety.
Pirelli is also introducing the Modular Integrated Robotised System (MIRS) at the factory. This manufacturing process uses robots to manage productivity and quality. The system creates a link between product design and application. This update is intended to increase the production capacity of the site.
The Georgia plant has operated for over two decades and includes a research and development centre. The facility uses natural rubber certified by the Forest Stewardship Council.
Claudio Zanardo, CEO of Pirelli North America, said, “The start of Cyber Tyre production in our Rome, Georgia plant is a significant milestone for Pirelli in this country. It reflects our commitment to bringing advanced technologies like Cyber Tyre closer to the market, further strengthening our industrial footprint and innovation capabilities in the United States.”
Yokohama Rubber Deploys AI And Simulation-Based Mould Design System

- May 04, 2026
The Yokohama Rubber Co., Ltd. developed a proprietary tyre mould design support system in April 2026, integrating finite element method (FEM) simulations and the company’s own artificial intelligence technology. This new tool is designed to augment the expertise of development personnel, enabling even less experienced staff to efficiently design moulds. It achieves this by providing data derived from numerous virtual experiments, which clarify how different mould design factors influence tyre characteristics.
The system accelerates mould development, lowers costs and minimises the rework typically associated with realising new designs. Furthermore, by fostering a multi-perspective understanding of the links between mould design elements and tyre performance, the tool equips Yokohama Rubber’s developers with fresh insights. These discoveries are expected to aid in creating tyres capable of achieving higher performance levels.
Developed under Yokohama Rubber’s HAICoLab AI concept launched in October 2020, the system addresses longstanding challenges. Mould design critically affects tyre traits, but traditionally understanding this relationship required expensive, time-consuming trial production and evaluations. The process also depended heavily on the tacit know-how of highly experienced staff, leading to variations in accuracy and development time based on individual expertise.
The support system resolves these issues through automated simulations and AI-based prediction and visualisation. It first generates numerous tyre FEM models with varied mould shapes and calculates their characteristics in a virtual space. These results train an AI surrogate model that instantly predicts design factor-performance relationships. By applying explainable AI technologies like SHAP and Partial Dependence Plots, the company’s developers can quantitatively visualise each factor’s impact, easily determining necessary adjustments to achieve targeted tyre characteristics.
