Import Bo-Carbidesi-Carbide Venturi Sandblasting Nozzle — Buy in Bulk from Supplier in China

The Bo-carbideSi-Carbide Venturi Sandblasting Nozzle from Zhuzhou Better Tungsten Carbide Co., Ltd is a wear-resistant blasting component manufactured in Zhuzhou City, Hunan Province, China. This nozzle employs a Venturi geometry to accelerate abrasive media through a converging-diverging profile, producing higher particle velocity and more uniform spray patterns than straight-bore designs. The supplier offers three liner material options: tungsten carbide, boron carbide, and silicon carbide, each selected against the abrasiveness of the blasting media and required service life. Available nozzle types include single inlet and double inlet Venturi configurations, with sizing from 4.8 mm to 9.5 mm bore diameter indicated by the packaging data.

The nozzle body is produced through sintering and hot pressing, the standard consolidation methods for cemented carbide and advanced ceramic components. Tungsten carbide liners offer robust all-round performance for steel grit and coal slag applications. Boron carbide provides superior hardness for aggressive abrasives like aluminium oxide, though with somewhat reduced impact toughness. Silicon carbide presents a cost-effective intermediate for moderate-duty work with walnut shell or crushed glass media. Zhuzhou Better states that customised products are available, including laser marking for fleet or rental asset tracking.

Primary applications include rust and corrosion removal, surface pretreatment before coating, refurbishment of worn industrial parts, creation of decorative textures on metal and stone, and deburring of castings and machined edges. Buyers are sandblasting contractors, shipyards, automotive restoration shops, and manufacturing plants with in-house surface finishing operations. The nozzles are compatible with standard blasting hoses and couplings, with double inlet variants suited to cabinet systems where balanced abrasive flow reduces hose wear. Sourcing should clarify exact liner material, inlet thread specification, and whether the quoted price is for single units or carton quantities.

Zhuzhou Better Tungsten Carbide Co., Ltd is located at Building 12-305, Da Han Hui Pu Industrial Park, No. 1318 Huanghe North Road, Tianyuan District, Zhuzhou City, Hunan Province, China, with postal code 412000. The company operates from an industrial park setting in Zhuzhou, a city recognised as a major Chinese cluster for cemented carbide and hardmetal production. Its product focus is tungsten carbide and related advanced ceramic products for abrasive wear applications, with sandblasting nozzles representing a defined product line alongside potential broader carbide component manufacturing. The supplier's trust tier is listed as Harbor, with a response rate of 0.00% and zero average response hours, suggesting unverified communication performance that buyers should test before committing to orders.

The company emphasises material choice flexibility, customisation capability, and laser marking services as competitive strengths. It does not disclose factory size, annual output, quality management certifications, or specific export market experience in the available profile. Buyers should independently verify ISO 9001 or equivalent quality system certification, production capacity for the stated bore size range, and whether the company manufactures liners in-house or sources from sub-contractors. The supplier's technical support capability, sample policy, and complaint handling procedures are also not documented and require direct enquiry.
