Automotive brake disc automatic coating production line

Brake discs are core safety components of the braking system, and their coating quality directly determines anti-corrosion performance, export inspection approval, and overall production cost. Traditional manual spraying and outdated overhead conveyor lines often suffer from uneven coating thickness, high rework rates, limited environmental compliance, and rising labor costs. With years of expertise in brake component coating, Jimeite has developed a one-stop, eco-friendly fully automated coating production line, making it the preferred upgrade solution for leading brake disc manufacturers.

Targeted Pretreatment System

Addressing issues such as oil contamination and rust accumulation in brake disc grooves and cooling channels, the customized multi-stage degreasing and precision phosphating process ensures no residual contaminants in internal cavities, fundamentally eliminating coating delamination and local missing coating defects.

Flexible Multi-Process Options

Oil-based coating: Strong adhesion, excellent coverage, high coating hardness, and stable overall protection performance, suitable for conventional mass production and general working conditions.

Water-based coating: Low VOC and environmentally friendly. Smooth spraying without sagging, uniform and aesthetically pleasing surface finish, combining corrosion resistance and appearance quality, fully compliant with environmental regulations and export standards in various regions.

Dacromet / Geomet coating: A long-life anti-corrosion system featuring thin and uniform coating layers, outstanding salt spray resistance, and excellent resistance to corrosion, humidity, and heat. Perfectly meets high-end automotive parts and export inspection requirements.

Intelligent Fixture & Vision Positioning
Automatically identifies multiple brake disc specifications, enabling flexible multi-product mixed production. No downtime or tooling changes are required when switching models, allowing seamless changeover between different product types.

Fully Automated Process

Automatic loading → pretreatment → coating → drying → cooling & unloading. The entire line requires only 1–2 operators, reducing labor requirements by more than 60% compared with traditional production lines.

Robotic Closed-Loop Spraying System

Six-axis robots combined with workpiece rotation improve coating utilization by 30%, significantly reducing material consumption. Precise film thickness control reduces defect rates to below 1%, eliminating most rework losses.

MES Data Traceability System

The production line is equipped with an intelligent central control system. Temperature, bath solution parameters, and production data are recorded in real time, allowing instant retrieval for OEM audits and third-party inspections.
