【Case Study】Achieved Significant Maintenance Cost Reduction and Fully Automated Paint Removal | LF Blast Room

In blast processing for large-scale structures, aren’t the most important concerns “running costs after installation” and “ease of use in real production environments”?

“Will maintenance frequency really be reduced?”

“Can it handle special or non-standard workpieces?”

Here, we introduce successful case studies of companies that have actually installed Fuji Manufacturing’s “LF Blast Room,” along with real voices from the shop floor. These examples are sure to provide valuable insights for solving the challenges at your factory.

Case Study 1: Construction Machinery Parts Manufacturer (Reduced maintenance costs / Enabled thin-plate processing)

【Challenges】

In surface preparation before painting large construction machinery parts (up to 6 tons), the key challenges were reducing operator workload and processing thin plates, which had been difficult with conventional equipment.

【Results After Installation】

By introducing the LF Blast Room, which allows the use of alumina abrasive media, improvements were achieved in operability, cost efficiency, and processing quality.

・ Reduced operator workload:

“The hose is thin and easy to handle, and visibility is excellent, which significantly reduced the burden on operators.” (Customer comment)

・ Significant reduction in maintenance costs:

“The recovery pipes have been in use for five years without any issues caused by wear, which greatly reduced both construction costs and maintenance frequency.” (Customer comment)

・ Thin-plate processing made possible:

“With conventional steel-grit blasting, thin plates would warp and could not be processed. By switching to alumina blasting, we are now able to process thin materials, greatly expanding our product range.” (Customer comment)

Point: Because it uses an air-powered recovery system that does not rely on conveyors, the LF Blast Room enables near maintenance-free operation, even when using highly abrasive alumina media.

Case Study 2: Semiconductor Manufacturing Equipment Manufacturer (Solved installation location constraints)

【Challenges】

The customer needed to perform surface preparation before painting for large components with a maximum processing weight of 5 tons (2 m wide × 2 m long), but faced limitations due to the factory location and installation conditions.

【Results After Installation】

Thanks to the proprietary low-floor design, the LF Blast Room was successfully installed even in a factory with strict installation constraints.

・ Installable even in coastal areas:

“Our factory is located in a coastal area, and we were unable to excavate a pit deeper than 1.5 meters. However, even when aligned with the floor level, the required pit depth was less than 1 meter, allowing the equipment to be installed without any issues.” (Customer comment)

Point: The LF Blast Room can be installed even in areas with high groundwater levels or in leased factories with restrictions on foundation work.

Case Study 3: Large Roll Processing (Fully automated paint removal / Enhanced safety measures)

【Challenges】

Paint removal for extremely large rolls measuring 0.76 m in diameter, 6.2 m in length, and weighing 10 tons.

Manual operation involved significant safety risks and raised concerns about inconsistent processing quality.

【Results After Installation】

A solution was adopted in which all processes were fully automated, including loading and unloading using a self-propelled cart, roll rotation, and blast gun movement.

・ Achieving both full automation and safety:

“We adopted a self-propelled cart system for transporting large, heavy workpieces. Safety measures unique to automation were implemented, such as safety laser scanners to monitor cart movement and camera units for real-time monitoring inside the system. Combined with the automated blasting process, this allowed us to operate with confidence and peace of mind.” (Customer comment)

Point: Beyond providing a simple “blast room,” we also specialize in building unmanned and labor-saving systems by integrating robots and automated equipment.

Support System of FUJI BLASTECH (THAILAND)

We provide technical support in Thailand with the same level of quality as Fuji Manufacturing in Japan.

・ Customized design:

We design the optimal blast room size and material handling method according to your factory space and workpiece dimensions (with proven experience handling workpieces of up to 40 meters in length).

・ Local support in Thailand:

Based in Samut Prakan, our team of Japanese and Thai staff responds quickly, providing support from installation supervision through after-sales maintenance.

【Free】 Would you like to test the effectiveness with your own samples?

“I understand the catalog and case studies, but I can’t make a decision unless I test it with our own products.” For production engineering professionals who feel this way,

we offer free test processing at our demo center in Samut Prakan, Thailand.

By bringing your actual workpieces (test samples), we will select the most suitable option from over 400 types of abrasive media, allowing you to verify processing quality and equipment performance on the spot. (※Test quantity subject to consultation.)

You can also clarify questions firsthand using the actual machine such as the differences between direct pressure systems and gravity systems, and the effectiveness of alumina abrasive media.

We look forward to your inquiry.
