Shrinker

The shrinking process is, as expanding, the most economical means of forming and / or sizing a wide range of parts having a continuous cross-section. Shrinking is the opposite of expanding, with the product being formed or sized from the outside diameter by exceeding the material yield stress during compression. This compression is used to reduce diameters. Forces act radially inward toward the machine centerline. The force required is higher than for the expanding process. The advantage is that improvements of the material properties are generated by a lower deformation. Shrinking is preferred over other forming methods when the diameter of the part is relatively small and/or outside diameter accuracy of the finished part is critical. Shrinking can eliminate or reduce machining operations and therefore reduce cost per part, especially when the outside diameter is of importance. Advantages of our Shrinker High outside diameter accuracy No limitation on minimum diameters Unique for assembling different types of materials (ex. steel rings around rubber parts) Shrinking is the only process where a segment of a ring > 180° can be calibrated Measuring and calibrating of the outer ring diameter during the automatic cycle (gauge mode) Spring back compensation A unique programmable control system with a user-friendly interface that guarantees repeatability and accuracy Features of SizTech SizTech can help you to develop your product with shrinking technology SizTech can advise you, which applications are possible and which are NOT possible to shrink SizTech knows how to calculate the right shrinker for your application
