Liquid Painting Line for Titanium Alloy Forgings Surface Treatment with Glass

Glass Lubricant Coating Line for Titanium Alloy Forgings

Customized Surface Coating System for High-Temperature Forging Applications

This glass lubricant coating production line is designed for the surface treatment of titanium alloy forgings before heating and forming.

During high-temperature forging, titanium alloys require suitable surface protection and lubrication. A glass-based protective lubricant is applied to the workpiece surface before forging to form a functional coating layer for the subsequent heating and forming processes.

The coating mainly performs two important functions:

• Surface protection: Helps protect the titanium alloy surface from oxidation during high-temperature heating and forging.

• Forging lubrication: Reduces friction between the heated workpiece and forging dies, supporting smoother material flow during forming.

The coating equipment and production process can be customized according to the dimensions, weight, geometry, production capacity, and specific coating requirements of the titanium alloy components.

Role of Glass Lubricant in Titanium Forging

Titanium alloys are processed at elevated temperatures during forging. Under these conditions, surface oxidation and friction between the workpiece and tooling can affect both processing and final product quality.

Applying a suitable glass lubricant before forging creates a protective and lubricating layer on the titanium surface.

During the subsequent high-temperature process, this coating helps:

• Reduce direct exposure of the titanium surface to the atmosphere

• Limit high-temperature surface oxidation

• Reduce friction between the forging and die

• Improve lubrication during deformation

• Support material flow during forming

• Protect the workpiece surface during the forging process

The coating material and application parameters should be selected according to the titanium alloy, forging temperature, forming process, and lubricant manufacturer's requirements.

Coating Application System

The application section can be configured according to the workpiece geometry and required production capacity.

Depending on the project, the system can combine:

• Automatic spraying equipment

• Reciprocating spray mechanisms

• Manual spray guns

• Manual touch-up stations

• Coating supply equipment

• Workpiece positioning equipment

• Ventilation and extraction systems

Automatic spraying can be used for the main workpiece surfaces, while manual touch-up provides additional flexibility for complicated geometries or areas that are difficult to reach automatically.

This combination is particularly suitable when a production line needs to process forgings of different shapes and dimensions.

Material Handling System

Titanium alloy forgings can vary considerably in size and weight. The material handling system therefore needs to be engineered according to the actual products.

Depending on the project requirements, the production line can incorporate suitable conveyor and workpiece transfer equipment to connect the coating stages.

Key design considerations include:

• Maximum workpiece dimensions

• Maximum workpiece weight

• Workpiece orientation

• Required production capacity

• Spraying position

• Loading and unloading method

• Required process time

• Factory layout

For large or heavy forgings, a heavy-duty conveyor and customized carriers can be incorporated into the production line.

Typical Process Flow

The exact production sequence depends on the selected glass lubricant and forging process. A typical coating line can be arranged around the following operations:

Workpiece Loading → Surface Preparation → Glass Lubricant Application → Coating Treatment / Drying as Required → Inspection → Unloading → Transfer to Subsequent Heating and Forging

1. Workpiece Loading

Titanium alloy components are loaded onto the designated carrier or handling equipment.

Fixtures and workpiece positioning are designed according to product geometry, weight, and required coating areas.

2. Surface Preparation

Before application, the workpiece surface should meet the cleanliness and preparation requirements of the selected glass lubricant system.

The specific preparation method is determined according to the manufacturing process and coating specification.

3. Glass Lubricant Application

The protective lubricant is applied uniformly to the required surfaces.

Application parameters are controlled according to factors such as:

• Coating material

• Workpiece geometry

• Required coating thickness

• Spray characteristics

• Product temperature where applicable

• Subsequent forging requirements

Automatic spraying and manual touch-up can be combined where necessary to achieve the required coverage.

4. Coating Treatment and Drying

Where required by the selected lubricant system, the coated components undergo an appropriate drying or conditioning process before further handling.

Process conditions are determined according to the coating manufacturer's technical requirements and the actual forging process.

5. Inspection and Unloading

After coating, workpieces can be inspected for surface coverage and coating condition before unloading and transfer to the subsequent heating and forging operations.

Advantages of a Dedicated Coating Line

Consistent Lubricant Application

Controlled coating equipment helps provide repeatable coverage compared with less standardized manual application methods.

Suitable for Industrial Production

Conveyorized material handling and automatic spraying can support repetitive production of titanium alloy forgings.

Automatic and Manual Spraying Combination

Automatic equipment can handle the main coating operation, while manual spraying provides flexibility for complicated surfaces and different workpiece types.

Adaptable to Large and Heavy Forgings

The material handling system, carriers, and coating stations can be engineered according to the weight and dimensions of the actual products.

Process-Specific Engineering

The complete system is designed around the customer's forging process rather than applying a standard powder or liquid painting line configuration.
