Product Description
Shrinker / Stretcher Metal Forming Machines
High-Precision Sheet Metal Forming Solutions for Automotive, Aerospace, Shipbuilding, Construction, and Industrial Applications
Overview
Shrinker and stretcher metal forming machines are essential tools in the field of precision sheet metal fabrication. They are specifically designed to shrink, stretch, curve, dome, and straighten a wide variety of metal sheets, ranging from thin aluminum to heavy-duty stainless steel. These machines are indispensable for shaping body panels, structural components, and decorative parts in industries such as automotive, aerospace, shipbuilding, construction, and industrial manufacturing.
Our product portfolio includes a complete line of Kraftformer (KF) machines, hand-operated formers, pneumatic-powered units, and plier-type tools. Each machine is engineered with advanced technology, ensuring high forming accuracy, stable performance, and long service life.
With adjustable forming speeds, multiple working strokes, and ergonomic designs, these machines offer both precision control for small tasks and powerful performance for large-scale forming operations. Whether you are restoring a vintage car, manufacturing aircraft panels, or constructing architectural facades, our shrinker/stretchers deliver efficiency, reliability, and repeatability.
