Core Philosophy

99 + 1 = Perfect Delivery

Water heats to 99°C yet still does not boil — all that accumulation still falls short of the crucial final step. Only by insisting on technological innovation and refining every detail to close that vital final "1 degree" can we achieve a perfect delivery.

The Core Brand Philosophy of Jiujiu Jiayi

We stay true to this original aspiration — continuously optimizing process standards and refining equipment performance to deliver tailored, full-process, customized surface treatment solutions. Every delivery is a pursuit of that final "1 degree."

Innovation Drives Growth

A professional R&D team深耕 across surface treatment, automation control, and industrial eco-protection — three verticals where our innovative strength stands out.

Precision in Every Detail

The entire production chain strictly follows the ISO9001 quality management system. All lines are equipped with eco systems, and every process parameter meets local emission standards.

Custom Process, Perfect Delivery

Process flows are tailored to workpiece material, capacity targets, and anti-corrosion & cleanliness requirements — delivered as a one-stop, full-plant, intelligent turnkey service.

R&D Strength

R&D Strength · Three Core Verticals

With 70+ invention and utility model patents, we have achieved full in-house R&D across core hardware and software — including intelligent spraying control systems, closed-loop eco treatment, ultrasonic precision pretreatment, and smart warehousing & logistics.

Surface Treatment Tech

A full range of intelligent coating lines — cathodic electrophoresis, electrostatic powder coating, dust-free liquid painting, and silane passivation — with robotic auto-spraying and constant-temperature curing.

70+ Patents

Automation Control

Our in-house intelligent spraying control system enables end-to-end automated line management, while the smart conveyor & storage system realizes unmanned, automated flow across all workshop processes.

Fully In-House R&D

Industrial Eco-Protection

Every line is equipped with water recycling, exhaust purification, and solvent closed-loop recovery — helping manufacturers achieve green, compliant, low-carbon and stable production with ease.
