製品概要

製品概要

これらの特注板金曲げ加工部品は、住宅用および商業用エネルギー貯蔵システムやAC/DC EV充電設備の内部構造部品として特別に開発されたもので、モジュール保護筐体、位置決め取付ブラケット、固定支持フレーム、絶縁シールドシェル、補強曲げ板などが含まれます。回路基板、配線ハーネス、変圧器、電気モジュールを安定して保持するように設計されており、充電・エネルギー貯蔵機器内部の絶縁、構造補強、耐振動性、内部空間レイアウトにおいて重要な役割を果たします。

当社が解決した主要な処理課題(中核的な競争優位性)

  1. 薄板曲げ変形問題の解決

    極薄の冷間圧延鋼板/アルミニウム合金板は、曲げ加工後に反りや反発が生じやすい性質があります。当社では、特注の曲げ金型と分割加圧成形プロセスを採用することで、反発値を精密に制御し、成形後の平面度を厳密な範囲内に維持します。

  2. 複雑な多角度および深絞り曲げ公差ドリフトを克服する

    不規則な多曲げ加工を施したブラケットの場合、従来の加工方法では寸法公差が容易に逸脱してしまいます。しかし、当社独自のCNC曲げ補正技術は、全体の公差を±0.1mm以内に抑え、内部電子モジュールの高精度な組み立て要件を満たします。

  3. 二次曲げ後の同軸穴位置ずれを解消

    曲げ線に近い穴は成形後に位置がずれることがよくあります。当社では、穴の中心位置合わせと無理な嵌め込みなしでのスムーズなねじ込みを保証するために、曲げ前の位置決め穴配置と成形後の微調整を採用しています。

  4. 狭い曲げ溝における固定エッジ崩壊およびバリ欠陥

    狭くて深い曲げ加工溝は、端が潰れたり、バリが粗くなったりする傾向があります。そのため、当社では特殊な小型曲げパンチと、研磨後のバリ取りを徹底的に行うことで、内部部品の取り付け時に端をきれいに保ち、傷のない状態に仕上げています。

当社の工場力の強み

  1. 社内一貫体制の板金加工ワークフロー

    自社所有のレーザー切断、CNC精密曲げ加工、タッピング、リベット打ち、研削、表面仕上げ加工工場を保有し、外部委託は一切行わず、コスト管理の向上と完全な生産トレーサビリティを実現しています。

  2. 新エネルギー構造部品に関する専門的な経験

    EV充電器およびエネルギー貯蔵装置の内部ブラケットおよびハウジングに関する長年の高度な加工経験を持ち、電力機器の内部組立ロジック、放熱レイアウト、および耐干渉構造設計に精通しており、組立不良率を低減するためのDFM構造最適化提案を提供できます。

  3. 厳格なバッチ一貫性品質管理

    各バッチごとに初回品検査、工程内寸法検査、完成品全数サンプリング測定を実施することで、量産時の寸法変動を効果的に回避し、長期的な受注協力において安定した納期を実現します。

  4. 柔軟なカスタマイズサービス

    図面/サンプルに基づくOEMおよびODMのカスタマイズに対応しており、材質(SPCC、SGCC、アルミニウム、ステンレス鋼)、厚み、曲げ構造、穴の位置、表面処理(粉体塗装、ブラッシング、不動態化)、カスタマイズされたロゴマーキングなど、調整可能な仕様となっています。

適用シーン

7kW/11kW/22kW AC家庭用充電器、DC急速充電ステーション、家庭用蓄電池キャビネット、産業用蓄電池キャビネット制御モジュール、オフグリッド蓄電発電所内部組立用アクセサリのための内部構造ブラケットおよびモジュール保護シェル。

😩 Typical Buyer Pain Points
