Country: Turkey
Industry:Door Manufacturing
Equipment: Panel Bender + Press Brake
Application: Door Panels, Door Frames, Folded Door Skins, Side Panels, Reinforcement Parts, Sheet Metal Door Components
A door manufacturer in Turkey needed a more flexible and stable sheet metal bending solution for daily production. The customer produced metal door panels, door frames, folded door skins, side parts, reinforcement components, and other sheet metal door structures.
Door production requires both accuracy and flexibility. Large door panels need clean, consistent folded edges. Frame parts and reinforcement pieces may need different bending angles, different sizes, and different forming sequences. When the bending process is unstable, door assembly becomes slower and final product appearance may be affected.
To improve the bending workflow, the customer selected a combined STON solution: Panel Bender + Press Brake.

Before introducing the STON solution, the customer needed to improve bending consistency and reduce repeated manual adjustment during door panel production. The factory handled both standard door models and customized door parts, so one bending method could not cover all needs efficiently.
주요 과제는 다음과 같습니다:
For door manufacturing, bending quality directly affects assembly. If a door panel is not straight, or if a frame part is not accurate, the final door may show gaps, poor alignment, or uneven edges. The customer needed a process that could support both stable panel production and flexible part bending.
After understanding the customer’s door product structure and production workflow, STON recommended a combined solution using a CNC Panel Bender and a Press Brake.
The Panel Bender was used for repeated panel forming and edge bending. It helped the customer produce door panels and folded door skins with stable angles and consistent dimensions. The Press Brake was used for more flexible bending tasks, such as frame parts, reinforcement components, special bends, and smaller batch parts.

| 장비 | Panel Bender + Press Brake |
| 주요 공정 | 판금 절곡 및 모서리 성형 |
| 제품 유형 | Door panels, door frames, folded door skins, reinforcement parts |
| 핵심 가치 | Stable panel bending plus flexible part bending |
This combination gave the customer a more complete bending workflow instead of relying on only one machine for all parts.

The production process starts with prepared sheet metal blanks. These blanks may come from cutting, punching, or other upstream processes. After that, the parts are assigned to different bending equipment according to product type.
Large and repeated door panels are sent to the Panel Bender for automatic edge forming. Parts that need flexible bending, different tool setups, or special angles are processed by the Press Brake.
일반적인 작업 흐름:
Sheet Metal Cutting / Punching → Panel Bender for Door Panels → Press Brake for Frames and Special Parts → Door Assembly → Finished Door Production
This process helped the customer organize production more clearly. Instead of using one bending station for every part, the factory could divide work by product type and bending requirement.
The Panel Bender and Press Brake serve different roles in door manufacturing. The Panel Bender is suitable for repeated door panels and folded edges. It helps improve consistency during batch production. The Press Brake is suitable for flexible bending tasks, especially when parts vary in size, angle, or structure.

These parts require stable dimensions and clean forming before assembly. Good bending quality helps improve door alignment, surface appearance, and final product consistency.
After introducing the STON solution, the customer gained a more balanced bending process for door manufacturing. The Panel Bender improved repeated panel forming, while the Press Brake supported flexible bending for different door parts.
| Improvement Area | 고객 가치 |
|---|---|
| Bending Consistency | More stable angles for repeated door panels |
| Production Flexibility | Press Brake supports varied parts and special bends |
| Workflow Efficiency | Different parts can be assigned to suitable equipment |
| Door Assembly Quality | More accurate components support smoother assembly |
| Product Range | Better support for standard and customized door models |
| 인력 의존도 | Reduced repeated manual adjustment |
| 장기간 사용 | Suitable for daily door production and future product changes |
The main value was not only machine quantity. It was process matching. The right equipment handled the right part, making the whole door production workflow more efficient and easier to control.

The customer selected STON because STON provides CNC sheet metal automation and fabrication equipment for industrial manufacturers. STON’s product system includes panel benders, press brakes, turret punch presses, laser cutting units, flanging machines, automatic loading and unloading systems, and complete sheet metal production lines.
