Import Air Propane Supersonic Spray System Scheme — Buy in wholesale FOB from Supplier in China

Zhengzhou Lijia Thermal Spraying Machinery Co. Ltd offers the HA-2000, an HVAF (high-velocity air-fuel) Innocent system that uses compressed air and propane to accelerate metallic or cermet powders beyond 700 m/s onto a substrate. The rocket-engine-inspired spray gun produces flame velocities exceeding 2000 m/s through axial centre powder feeding, a configuration intended to improve particle heating uniformity and coating density. A full-closed-loop automatic control structure monitors all gas pressures in real time via inlet pressure sensors and regulators, with setpoints managed through a touch-screen panel.

The system stores and recalls process recipes, allowing operators to add, modify and save parameter sets for repeat jobs. A high-performance PLC governs module operation, fault alarm display and functional sequencing. Propane fuel and compressed air combustion represents the safest gas-mode configuration in the supersonic spray market, eliminating the explosion risks associated with oxygen-acetylene or hydrogen-fuelled alternatives. Coating properties include bond strength and porosity of 1 percent or lower, achieved through the high impact velocity and low oxygen content of the HVAF flame.

Typical applications include wear-resistant coatings on shafts, pump housings and turbine components; corrosion barriers for marine and chemical equipment; and dimensional restoration of oversized or worn parts. Buyers include aerospace maintenance shops, power generation overhaul contractors, oilfield service companies and heavy machinery manufacturers. The system handles up to 20 kg of powder per hour in production configurations. Because this is a customised scheme, buyers must communicate their substrate materials, coating specifications and production throughput requirements directly with Zhengzhou Lijia to define the exact equipment configuration, auxiliary components and installation support.

Zhengzhou Lijia Thermal Spraying Machinery Co. Ltd is located in Zhengzhou High-Tech Development Zone, Henan Province, China. The company presents itself as a developer rather than a pure reseller, citing an engineering team that introduced, absorbed and digested international advanced equipment and technology to create the HA-2000 system. The trust tier shown is "harbor" and the response rate is 0.00 percent, so buyers should not assume reliable digital communication and may need to engage through direct channels or a China-based representative.

No information on founding year, registered capital, headcount, annual revenue, or named clients appears in the available data. The supplier's location in Zhengzhou places it inland, with freight options including rail to coastal ports or air freight from Zhengzhou Xinzheng International Airport for urgent spares. Buyers evaluating this supplier should request references Istalled base references, proof of export experience, and documentation of after-sales support capabilities including spare parts availability and remote technical assistance.
