On June 26, 2026, the patent applied by Tietuo Machinery for “a foamed ceramic composite machine tool bed with flow channels and rib holes separated in layers” was officially authorized.
According to patent disclosure information, the new foam ceramic composite machine tool bed is based on foam ceramics and adopts a layered structure design internally. The upper layer is a cooling layer and the lower layer is a reinforcement layer. The two layers are completely isolated by a foam ceramic solid partition, structurally realizing that the cooling flow channel and the reinforced skeleton do not interfere with each other.
There are multiple parallel transverse flow channel holes arranged in the cooling layer, a sealing layer is set on the inner wall, and a medium inlet and outlet is reserved on the side wall, which can realize active temperature control during the operation of the equipment and greatly reduce the impact of temperature fluctuations on processing accuracy; a three-dimensional mesh intersection is set up in the reinforcement layer.
The fork’s strip hole structure, the internal filled reinforcement ribs and the base are solidified into one, forming a built-in reinforced skeleton, which takes into account structural strength, lightweight and high damping and vibration absorption performance. At the same time, the overall production process difficulty is much lower than that of traditional machine tool beds with the same performance, and has extremely high industrialization value.
Tietuo Machinery was founded in 2004 and listed on the Beijing Stock Exchange in 2024. It is the leading enterprise in the domestic asphalt mixing equipment track. It has long been engaged in the research and development, production and sales services of engineering machinery and equipment, and its technical strength and product quality rank at the forefront of the industry.
In 2025, the company will achieve an operating income of 375 million yuan and a net profit of 48.1827 million yuan. The core product, original regeneration integrated mixing equipment, accounts for more than 40% of the revenue. It has accumulated a large number of mature application cases in the fields of new urbanization and road infrastructure.
In addition to the foamed ceramic machine tool bed patent disclosed this time, Tietuo Machinery has accumulated more than 50 patents in various fields such as engineering machinery structural upgrades, new material component research and development, environmentally friendly exhaust gas treatment, and intelligent transformation of production processes since 2024, covering three major types: invention patents, utility model patents, and design patents. More than half of the patents have been officially authorized, and related technologies have been gradually applied to the company’s full range of products, effectively improving the market competitiveness of the products.
As global infrastructure demand continues to increase, Chinese construction machinery products backed by core technology patents are expected to gain a higher market share in the international market and provide higher-performance, more cost-effective Chinese solutions for the global infrastructure industry.
