Variotempo
新專利工藝 Variotempo 為成型技術重新定義了標準。
由於 Variotempo 在冷成型工藝限制方面實現了重大突破，以前多件式複雜部件可作為單一構件進行製造。除了省去接合過程和減少材料耗費，還降低了模具投資成本。這種新工藝適用於鋼製和鋁製構件。
Variotempo 還使汽車製造業輕型結構件製造有了更多選擇。由於大幅降低每個構件的重量，最多可達 60%。故此，在加工強度在 1200 Mpa 以下高強度和最高強度鋼板領域，這種方法堪稱具有革命性意義。儘管板厚減少，但車身仍具有相同強度。
首先，該成型工藝在 Allgaier 模具製造公司工程部進行了類比，然後，才逐步開發成熟可量產使用並申報專利。目前，Variotempo 在汽車製造業用於批量生產，可用於所有結構件，例如：碰撞加強件、橫向支撐件或耐磨板。
