The company's core technology stack spans investment casting (wax pattern/ceramic shell), precision machining, sand casting, surface treatment (electroplating), heat treatment, permanent mold casting, shell mold casting, 3D printing for molds, and specialized sheet metal resistance seam welding and GTAW processes. Products include mission-critical engine, hydraulic, transmission, fuel system, and structural components for automotive and EV gigacasting; superalloy investment castings and APU components for aerospace; precision parts for medical devices; and high-horsepower engine and industrial components. Through the Impro Fluidtek subsidiary (acquired from Danfoss Jiangsu in November 2022), the company also produces patented hydraulic orbital motors (RE, RE 550, WP/WR, WS360 series), and the FSMD subsidiary adds aerospace-qualified sheet metal welding for Boeing 737 Max APU housings.

Impro operates a B2B enterprise sales-led go-to-market targeting Fortune 500 OEMs and their Tier 1 suppliers, with direct field sales supported by Sales Engineers who manage APQP-compliant quoting, pricing negotiation, and account renewal across multi-year program lifecycles. Pricing is quote-based per purchase orders with material-cost adjustment clauses, and revenue is generated primarily through one-time manufacturing and sale of custom components. End markets are diversified across automotive, high-horsepower engine, construction equipment, agricultural equipment, hydraulic equipment, aerospace, medical, and energy, with named customers including Honeywell, GE Aerospace, Caterpillar, Cummins, Bosch, Parker Hannifin, HUSCO, BorgWarner, and SANY, several with partnerships spanning 13–15 years. FY2025 revenue reached HK$5,095.5 million (approximately USD 652 million), up 8.7% YoY, with profit attributable of HK$726.2 million (up 12.7% YoY), and management has guided to mid-double-digit sales growth for FY2026.
