Buzuluk

What Buzuluk does

Buzuluk a.s. is a Czech Republic-based manufacturer of industrial rubber processing machinery, headquartered in Komárov between Prague and Plzeň. The company designs, produces, sells and services a portfolio centred on calendering equipment (two-roll, three-roll and four-roll calenders, plus complete calendering lines) and mixing equipment (high-pressure internal mixers with tangential and interlocking rotors ranging from 2.5L to 437L, two-roll mills, batch-off/cooling units, twin screw extruders, roller-die calenders, and complete mixing lines), supplemented by rotary curing presses, baling presses for synthetic rubber and special calenders for non-rubber mixtures. Operations are vertically integrated around an in-house foundry that casts rolls (traceable to a 1460 ironworks origin) and an internal R&D centre for product development, with claims of more than 100 years of engineering production and nearly 90 years in rubber machinery.

The business model is enterprise B2B capital equipment sales with a lifetime aftermarket: pricing is quote-based and not publicly disclosed, machines are sold as standalone units or as complete turnkey lines through dedicated sales, spare parts and service departments, and customers are primarily global tire manufacturers and technical rubber product manufacturers (conveyor belts, seals, profiles, roofing, healthcare components, rubber boat parts). Go-to-market is direct enterprise field sales via phone, email and a multi-language corporate website (Czech, English, Russian, Chinese), supported by trade event presence, with products delivered to more than 40 countries across European, American, Russian and Indian markets. The company operates under ISO 9001 (since 1995), ISO 14001 (since 2002) and ISO 50001 (since 2018) certifications, is a privately held joint-stock company following a 2012 acquisition by DALIAN China, and its operating status is active with no parent company disclosed in the available sources.

Functional benefit

Products and services

• Three-roll calenders Three-roll calenders with Y or I configuration for foil drawing and rubberizing applications. Roll diameters from 300mm to 710mm with various lengths and power ratings. Used for rubberizing textile or steel cord and producing rubber foils for tires, conveyor belts, tyre tubes, and technical rubber products. Features include roll crossing, bending, pre-loading, and hydraulic gap adjustment for thickness accuracy.
• Four-roll calenders Four-roll calenders with F, S, or Double I configuration for foil drawing, steel cord, textile cord, conveyor belts, and PVC applications. Roll diameters from 250mm to 710mm. Features include independently driven rolls with maximum speed accuracy and friction adjustment, and each cylinder is supplied with a quality certificate.
• High-pressure internal mixers High-pressure internal mixers for preparing rubber compounds, available in tangential and interlocking rotor configurations. Mixing chamber volumes range from 2.5L to 437L. Models with special geometry are available for specific compounds, with features including X-ray testing for internal defects and water pressurization during production.
• Two-roll mills Heavy-duty two-roll mills for rubber processing. Roll diameters from 160mm to 750mm with various lengths, speeds, and power configurations. Surface hardness of rolls is 500 ± 20 HBr at depth of 10-15 mm, with both cavity cooling and under-surface drilled cooling channels available. Manufactured using the company's own foundry for roll casting.
• Batch-off units (coolers)
