Changsha VIBO New Materials Co., Ltd.

Changsha VIBO New Materials Co., Ltd. is based in the Liuyang National Economic and Technological Development Zone, Changsha, and specialises in metal-matrix wear-resistant composites. The portfolio covers vacuum-brazed bimetallic composites, cast bimetal, high-chromium and Ni-hard irons, tungsten carbide and ceramic-inserted castings — replaceable life parts for mining, cement and aggregates, sugar milling, dredging and ports, power and steel, and recycling.

Wear parts sit at the downstream metal-products stage of the advanced steel materials chain: steel plate upstream, consumable life parts for heavy industry downstream. VIBO builds upward from vacuum-brazed bimetal into cast composites, forming a single source that spans material, blank, finished part and application engineering. The company also supplies wear spares to the construction machinery chain.

The site covers 100 acres with 55,000 m² of workshop space and more than 300 employees, generating annual output value above CNY 300 million. Capacity for bimetallic composites and other metal wear parts exceeds 18,000 tonnes per year, with the flagship “Doubletuff” wear-block line contributing over 10,000 tonnes. More than 5,000 standard patterns are held in stock tooling and standard lead time is held within 30 days.

Main Products

• Vacuum-Brazed Bimetallic Wear Blocks — tips, shanks, hammers, rectangular bars and blocks, grizzly bars, sliders; Doubletuff series
• Cast Bimetal Parts — cast liners, bucket teeth, edge shrouds, cold- and hot-cast corner heel shrouds
• High-Chromium & Ni-Hard Iron Parts — high-Cr liners, concave segments, top-shell blocks, reclaimer bucket liners, high-Cr pipe fittings and flanges
• Ceramic-Inserted Castings — ceramic, carbide and TiC-rod inserted castings, ceramic-composite roller sleeves, feed chute liners (CR27+ZTA)

Manufacturing and quality

Every process step is carried out in-house with no outsourcing; single-pour capacity exceeds 10 tonnes, supported by 500–2,500 kg medium-frequency induction furnaces, vacuum brazing and heat-treatment furnaces, coated-sand and sodium-silicate sand lines, CNC machining, cutting and hardfacing equipment. The company is certified to ISO9001, ISO14001 and ISO45001 and runs six laboratories equipped with spectrometers, carbon/sulphur analysers, universal testing machines, hardness testers, ultrasonic flaw detection, metallographic microscopy, high/low-temperature impact testing and an ASTM-G65 simulated wear tester.

Standards and R&D

A Chinese standard-setter for vacuum-brazed bimetallic composites, working with the State Key Laboratory of Central South University; a high-tech enterprise since 2015, holding 15 invention patents plus utility models, and recognised as a national “Specialized, Refined, Differential and Innovative Little Giant”.
