Heavy Machinery Automatic/Manual Liquid Spray Painting Equipment Line with Conveyor System

Heavy-Duty Protective Coating System for High-Temperature Metal Forming

CHG provides customized glass lubricant coating production lines for titanium alloys and other high-performance metal components requiring protective surface treatment before hot forging.

Unlike conventional decorative painting or powder coating, glass lubricant application is a specialized industrial process intended to support subsequent high-temperature forming operations.

The coating forms a protective and lubricating layer on the workpiece surface, helping reduce oxidation during heating and friction during forging.

This production line combines automatic liquid spraying, manual supplementary application, and a heavy-duty accumulation conveyor to handle large metal components with different shapes and coating requirements.

The conveyor system is designed to accommodate individual workpieces weighing up to 2 tons, with equipment configuration customized according to the product dimensions, process requirements, and available workshop space.

Specialized Applications in Metal Forging

The spraying system can be engineered for different categories of high-performance metal products.

Titanium alloys are widely used in applications requiring high strength, relatively low density, and resistance to demanding operating conditions.

During high-temperature forging, titanium surfaces are susceptible to oxidation and interactions with the surrounding environment.

Applying a suitable glass-based protective lubricant before heating can help reduce surface oxidation and improve forming conditions.

Selected nickel-based and other high-temperature alloys may require specialized protective or lubricating coatings during hot-working operations.

The coating formulation and application process must be compatible with the alloy, heating temperature, and forming requirements.

Certain steel forging processes may also benefit from specialized lubricating coatings.

For these applications, the coating material and processing conditions are selected according to the steel grade and forging procedure.

Main Production Line Configuration

The system integrates coating application equipment with controlled workpiece transportation.

Additional equipment can be incorporated according to the coating material, required preparation process, and project-specific operating conditions.

Automatic Glass Lubricant Application

The automatic spraying section is designed to apply the selected glass-based coating material to the required workpiece surfaces.

Spray equipment is configured according to the coating formulation, product geometry, application requirements, and desired production capacity.

Depending on the project, the automatic system can incorporate controlled spray gun positioning and coordinated workpiece movement.

Automatic spraying can provide:

• Repeatable application sequences

• Controlled spray gun movement

• Reduced dependence on manual spraying for regular workpieces

• Consistent operating conditions

• Integration with conveyor positioning

• Improved production flow for repeated component designs

The actual coating thickness and coverage depend on the material properties, spray parameters, workpiece geometry, and process settings.

Forging blanks and preforms may contain curved surfaces, recesses, irregular contours, or other geometries that are difficult to cover using a fixed automatic spraying arrangement.

Manual spray stations provide additional flexibility for these applications.

Operators can adjust the spray gun angle, distance, and working position to reach areas requiring supplementary coating.

The combined automatic and manual arrangement is particularly suitable for production involving different component designs or workpieces with complicated surface geometries.

Manual spraying can also be used when product changes require additional application flexibility.

Heavy-Duty Accumulation Conveyor

The production line incorporates a heavy-duty accumulation conveyor for transporting metal components between processing stations.

The system is designed for workpieces weighing up to 2,000 kg each.

Its mechanical structure, carriers, and drive arrangement are developed according to the actual workpiece load, dimensions, center of gravity, and required movement sequence.

The conveyor supports controlled movement and positioning of heavy components during the coating process.

Depending on the final system design, carriers can be stopped or accumulated at designated locations to coordinate spraying and handling operations.

Different forging components require different support and suspension arrangements.

Carrier design takes into account:

• Maximum workpiece weight

• Overall dimensions

• Center of gravity

• Workpiece orientation

• Required spraying access

• Loading and unloading method

• Carrier spacing

• Conveyor operating conditions

Suitable fixtures help maintain stable positioning throughout transportation and coating.

The conveyor control system can be coordinated with automatic spraying equipment so that workpieces are positioned appropriately during application.

This allows the material handling and spraying operations to function as an integrated production process.

Why Glass Lubricant Coating Is Important in Titanium Forging

Titanium alloys are sensitive to high-temperature surface reactions during heating and deformation.

A suitable glass-based lubricant can provide two important functions: thermal surface protection and lubrication during forming.

When titanium alloys are exposed to elevated temperatures, oxidation and oxygen diffusion can affect the surface condition of the material.

Certain glass-based protective coatings form a barrier that helps limit interaction between the metal surface and the surrounding atmosphere.

This can contribute to reducing oxidation-related surface degradation during the heating stage.

The effectiveness of the protective layer depends on the coating composition, application quality, heating temperature, and exposure duration.

During hot forming, friction develops between the workpiece and the forming tools.

A suitable glass lubricant can reduce interfacial friction under the intended forging conditions.

Improved lubrication may help reduce tool wear and support more controlled material flow during deformation.

Lubrication conditions influence the interaction between the forging dies and the metal workpiece.

An appropriately selected coating can contribute to more consistent forming conditions, particularly for components with complex shapes or demanding deformation requirements.

The actual performance must be evaluated according to the alloy, forging temperature, die design, and selected lubricant formulation.

Typical Coating Process

A glass lubricant spraying operation can be arranged around the following stages:

Workpiece Loading → Surface Preparation → Glass Lubricant Spraying → Supplementary Manual Application → Coating Drying (If Required) → Inspection → Unloading

The final process sequence depends on the selected coating material and forging requirements.

Forging components are placed onto suitable conveyor carriers or fixtures.

For heavy products, mechanical handling equipment may be incorporated according to the workpiece dimensions and weight.

Before applying the glass lubricant, the workpiece surface is prepared according to the coating supplier's requirements.

The objective is to provide suitable conditions for coating application and adhesion during subsequent handling and heating.

Automatic spraying equipment applies the selected protective lubricant to the required surfaces.

Spray gun arrangement, application distance, and coating parameters are selected according to the product geometry and coating material.

Operators apply additional coating to areas that require special attention.

This stage provides flexibility when processing irregular or complex forging components.

Where required by the selected coating formulation, the coated workpieces undergo drying or another specified conditioning process before subsequent handling.

The necessary conditions depend on the lubricant manufacturer's technical requirements.

After coating, the workpieces can be inspected for coverage, visible defects, and other application-specific requirements.

Finished components are then transferred to the next manufacturing operation, such as heating and forging.

Advantages of the Combined Spraying System

Suitable for Large and Heavy Components

The accumulation conveyor is designed to handle individual workpieces weighing up to 2 tons.

Automatic spraying supports repeatable operations, while manual stations provide additional control for irregular shapes and difficult-to-access areas.

The accumulation conveyor allows workpieces to be transported and positioned according to the production sequence.

Spraying equipment, carriers, and conveyor arrangements are developed around the actual forging components and coating material.

The coating system can be configured as an upstream preparation process before heating and hot forming.

Typical Industrial Applications

The system can be considered for protective lubricant application on components used in:

• Aerospace titanium alloy forging

• High-performance alloy manufacturing

• Industrial hot forging

• Heavy machinery component production

• Specialized metal forming operations

• Large forged structural components

• High-temperature alloy processing

The suitability of a glass lubricant coating process depends on the alloy, forging method, heating conditions, and required coating properties.
