Sanjun Hardware was selected for its precision sheet metal technology, professional interface design capabilities, and proven track record in industrial multimedia enclosure customization.
コア部品製造プロセス
The multimedia panel enclosure consists of the main enclosure, top ventilation cover, front interface panel, and mounting brackets. All production follows ISO 9001 quality standards and industrial multimedia enclosure specifications.
1.材料選択と、前処理
- メインハウジングと、パネル：1.0 mm冷間圧延亜鉛めっき鋼板、高い構造強度と基本耐食性を持つ。
- 前処理：全自動超音波脱脂、錆除去とリン化、洗浄、高付着力の表面基材を形成し、静電粉末塗料の理想的な選択である。
2.コア製造プロセス
- Precision Laser Cutting: 8000W fiber laser cutter with ±0.02mm tolerance, using nitrogen assist gas to minimize heat distortion and maintain material integrity. This ensures accurate cuts for ventilation holes, interface port cutouts, and mounting slots.
- CNC Bending & Forming: 9-axis CNC bending machine with custom jigs, ensuring springback ≤0.02mm and consistent structural dimensions. This is critical for the precise alignment of interface ports and the tight fit of the enclosure.
- Precision Hole Processing: Laser positioning and CNC punching technology are used to ensure the accuracy of interface port openings, mounting holes, and ventilation slots within ±0.01mm. This guarantees seamless integration with standard HDMI, USB, and power connectors.
- Heat Dissipation Structure: Precision-punched ventilation holes on the top and side panels, designed to optimize airflow and maintain optimal operating temperatures for internal multimedia components.
- せいでんふんまつふきつけ
- Assembly & Sealing: High-density foam gaskets embedded in the enclosure seams to ensure a tight seal. Reinforced mounting brackets with precision holes are integrated into the enclosure for secure wall installation, while snap-fit locking tabs enable quick and reliable assembly of internal components.
3.品質管理と、テスト
- Dimensional inspection: CMM measurement to confirm tolerance ≤±0.03mm and compatibility with standard interface ports.
- IP 54保護試験：IEC 60529標準に基づいて防塵防水試験を行う。
- 放熱試験：熱イメージングを行い、フルロード下の有効気流と温度制御を検証する。
- Interface fit test: Assembly testing with the client’s multimedia connectors to ensure seamless fit and signal integrity.
- 全機能検査：納品前に100%検査し、欠陥がない。
プロジェクトの課題と、ソリューション
1. Challenge: Precision Alignment of Multi-Interface Ports
The multimedia panel features a complex front panel with multiple interface ports (HDMI, USB, power), requiring extremely high precision to ensure seamless component integration and signal integrity.
解決策: We used a combination of laser cutting and CNC punching with real-time positioning feedback. Pre-production sample assembly was conducted with the client’s hardware to verify fit before mass production, ensuring all ports aligned perfectly.
2. Challenge: Slim Design with Structural Integrity
The enclosure must be slim for wall-mounted installations, yet strong enough to support heavy internal multimedia modules and withstand mechanical shock.
解決策: Through finite element analysis (FEA), we optimized the internal structure with lightweight reinforcing ribs, improving structural strength by 20% without increasing the overall thickness.
3.課題：小ロットでカスタマイズされた高い一貫性
The customer required 800 units with uniform appearance, size, and performance across all units.
解決策自動ラインおよび統計プロセス制御（SPC）は、加工パラメータをリアルタイムで監視するために使用される。25ユニットごとにサンプリング検査を行い、寸法、表面仕上げ、機能性能の安定性を確保した。
4. Challenge: Compatibility with Standard Multimedia Components
The enclosure must seamlessly accommodate standard multimedia modules and interface components.
解決策: We used laser positioning technology to ensure the accuracy of mounting rails and component slots within ±0.01mm. Pre-production sample assembly was conducted with the client’s hardware to verify compatibility before mass production.
プロジェクトの成果
- Delivery: 800 units completed and delivered 4 days ahead of the 30-day schedule, with a 100% pass rate in all tests.
- Performance: Enclosures operate stably in both commercial and office environments, with no overheating, dust accumulation, or structural issues reported. The slim, lightweight design has improved installation flexibility and user experience for end-users.
- Partnership: The client signed a 2-year strategic cooperation agreement, appointing Sanjun Hardware as the exclusive sheet metal enclosure supplier for its full line of multimedia panel products.
