High-Precision Sheet Metal Forming Solutions for Automotive, Aerospace, Shipbuilding, Construction, and Industrial Applications
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.
Open Height (Between Upper and Lower Die): 210–295 mm
Adjustable Punch Feed Range: 8 mm
Punch Stroke (Oscillation): 80 mm
Vibration Frequency: 0–600 strokes/min
Maximum Forming Thickness:
Steel (σ = 450 MPa): 6 mm
Aluminum (σ = 250 MPa): 8 mm
Copper (σ = 250 MPa): 8 mm
Stainless Steel (σ = 450 MPa): 4 mm
Machine Weight: 2,542 kg
Overall Dimension: 2580 × 1321 × 2400 mm
This high-performance unit is capable of handling various metals with different strengths, ensuring reliable forming results even on high-tensile alloys.
Body panel shaping: Shrinking, stretching, and straightening of doors, fenders, roofs, hoods, and other body components.
Accident repair: Restoring deformed panels to their original contour without replacing the entire part.
Vintage car restoration: Precisely shaping curves, domes, and edges while preserving the authentic look and feel of classic vehicles.
Custom fabrication: Perfect for hot rod builders, racing teams, and prototype vehicle development.
Fuselage panels and structural components: Forming lightweight yet strong panels made of aluminum, titanium, or other alloys.
High-precision parts: Achieving tight tolerances, smooth surfaces, and stress-free shapes required in aerospace design.
MRO (Maintenance, Repair, Overhaul): Restoring or reshaping damaged aircraft skins and components to reduce replacement costs.
Hull sheet processing: Stretching and doming large sheets to form curved hull structures.
Structural component forming: Creating arched frames, bulkhead reinforcements, and deck elements.
Repair and refit: Straightening and reshaping corroded or damaged marine panels.
Roofing and facade sheet processing: Forming complex metal shapes for roofing tiles, curtain walls, and facade cladding.
Decorative and structural parts: Producing ornamental designs, curved facades, and precise angles for modern architecture.
Restoration work: Perfect for repairing or replacing decorative sheet metal details on heritage buildings.
General sheet metal forming: Ideal for enclosures, cabinets, machinery housings, and precision components.
