PivaPunch Coil Nesting

Our nesting systems today gives you multiple options to run your parts. Customer can decide the part type, amount, and the order in which you want the parts to exit the system.

The traditional way of sheet metal coil nesting is perceived as suitable for mainly big parts as large batches. For Pivatic both of these arguments are false. We challenge you with a thought: one million parts a year, each one of them different.

We have been producing coil punching machines since 1975 and have seen the trends change in part production. The batch sizes are getting smaller and the need for flexibility increases. Based on our current customers we have identified and adapted to three different production methods.

Batch Production

The most efficient way is the batch production, where you run the weekly, monthly or even yearly requirement of a single part in one go. The deciding factors are the cycle time and material optimization. Parts are usually stacked ready for storage. In Pivatic we choose the optimal coil width for nesting the required parts and split all parts from the nest with single shear strokes. You get the best possible edge quality in all part sizes.

Kit Production to optimize material

When the batch sizes are smaller, are based on orders or there is limited storage space, you might only need 10 or 100 parts at a time. To optimize material in this scenario, is usually is beneficial to produce 1-3 parts more or less since you are producing from a continuous strip instead of a standard sheet. The cost of the extra parts is usually compensated by the saved material. 

Kit Production in the correct order

When there is a follow-up process after Pivatic, most commonly assembly, it is possible to produce only the required amount of parts and in the correct order. This means that batch size of one is possible. The material optimization lacks but you will not produce any unneeded parts or skeletons to complicate the process.
