Wiper Die

One of the biggest challenges encountered in tube bending operations is the formation of wrinkles at the inner radius of the bend. Wiper Die, commonly known as the “Spoon,” is a critical die component designed to eliminate this problem. Wiper Die solutions produced on Somut Makina’s high-precision production line ensure flawless surface quality, particularly in thin-walled pipes and tight-radius bends.

Technical Excellence and Material Advantage

Spoon dies fit snugly against the inside of the pipe during the bending process, controlling the flow of material. This prevents metal buildup and ensures a smooth finish. At Somut Makina, the high-quality bronze alloys or specially coated steels we use in our production minimize friction, thereby extending the lifespan of both the die and the tube.

Key Technical Features:

Flawless Surface Finish: Completely prevents the formation of ripples and wrinkles on the pipe’s inner diameter.
High Wear Resistance: Options include specially heat-treated or high-quality bronze materials that maintain their shape under continuous friction.
Precise Geometry: End structure machined with millimeter-level tolerances, 100% compatible with pipe diameter and bending radius.
Easy Installation: Adjustable design that integrates quickly with standard pipe bending machines.

Every project has different bending parameters. Therefore, in addition to standard sizes, we produce customized spoon dies tailored to your pipe material (stainless steel, aluminum, copper, etc.) and the difficulty level of the bend. Thanks to our in-house production advantage, we provide full support to your business during die revisions and fast delivery processes.
