Steel Production Board 3d Scanning Quality Inspection

Completed with Precision Manufacturing Technology, Proven by Rigorous Quality Verification.

Samjung precisely manages the dimensional accuracy and flatness of steel production boards through precision cutting and four-stage leveling technology. We also apply systematic quality control standards from incoming materials to the final product and fully inspect the flatness of products with 3D scanning and AI vision inspection systems. Through precise quality control across the entire manufacturing process, we secure consistent product quality and stable production performance.

Flatness Made Precise,
Surface Made Harder

Leveling corrects the curvature of the steel production board, and the improvement in surface hardness from post-processing
was confirmed by testing.

To allow stable, long-lasting use in repeated production environments,
we consider flatness and surface hardness together.

Post-Processing Effect Confirmed by Testing

The same positions on an HS540 steel production board were measured before and after leveling. The surface was ground to reduce the effect of scale, and the change in hardness at each point was compared.

Test Subject
2 HS540 steel production boards, 6 points each (P1–P6)
Measuring Equipment
Mitutoyo portable hardness tester HH-411
Measured Value
Shore hardness HS (per raw material notation)
Measurement Method
After grinding the measurement area, two measurements within 3 mm of each point were averaged and compared

Hardness Measurements by Point

Changes by point ranged from −0.70 to +1.75 HS,
with hardness increasing at 9 points and decreasing at 3 points. In this HS540 specimen, hardness tended to increase after leveling.

12 points were measured, and
hardness increased at 9 points.

Board 1 · P2 22.55 23.50 +0.95
Board 1 · P3 23.10 24.55 +1.45

Frequently Asked Questions

We have compiled the production conditions and board selection criteria that are often checked before adoption.

Samjung manufactures Steel Production Boards (Steel Pallet) using not only distinctive special steel grades but also proprietary manufacturing technologies and processes protected by patents. Drawing on expertise accumulated through years of research and development and precision manufacturing know-how, we deliver quality and performance that distinguish our products from those of other manufacturers, offering Steel Production Boards backed by Samjung’s proprietary technology.

Yes. Deformation can occur depending on operating conditions and maintenance.

Repeated production with loads exceeding the Steel Production Board’s allowable load, or continuous use of only one side, can cause deflection or deformation. In addition, as corrosion reduces the steel’s thickness, its load-bearing capacity can decrease, potentially increasing deformation.

For long-term, stable use, it is important to select an appropriate thickness and specifications based not only on the products you currently manufacture but also on your production plans for the next 10 years. During use, we recommend controlling corrosion and using a flipper to alternate between both sides.

One of the most important is precision manufacturing technology that maintains flatness over long periods of use. Cutting steel at high temperatures can cause subtle thermal distortion and residual stresses. Under repeated vibration and loading, these stresses can lead to gradual deformation, potentially affecting the bottom surface flatness, compaction uniformity, and density of concrete products over time.
Samjung Industries uses a proprietary four-stage leveling process to manage residual stresses. We design and manufacture our steel mold bases to achieve precise flatness at delivery while also accounting for potential deformation during long-term use.

Samjung conducts ongoing joint research with POSTECH and Handong Global University, both located in Pohang. Our in-house R&D center also reviews ways to improve each product’s performance and manufacturing processes every year while developing technologies needed for future production environments.

Research results are incorporated into product specifications and manufacturing processes after verification. Even when there are no major visible changes, we continuously improve details such as materials, structures, and processing methods, and Samjung’s products advance every year.

These improvements are incorporated into newly manufactured products. Therefore, even when purchasing the same product again, customers receive a more advanced version that reflects the research and development achievements made since their previous purchase.
