In our experience we can save our customers between 25-50% using this clever technique
In most of cases the cost of the raw material is the most expensive element of die cutting manufacture so we always try our best to maximize the part yield from the raw material. This is especially important with part drawings which call out 1 side with PSA (Pressure Sensitive Adhesive) or if the part itself is made from an adhesive tape. When purchasing any raw material which has an adhesive side it always has a high MOQ. Because the adhesive has a short shelf life the raw material must be produced by the OEM or the distributor as a order on demand – raw materials with adhesive are not held in inventory.
One of the main ways that we can keep our customers costs to a minimum is a strategy of making the dies with more than one part number on them – this is called “nesting”. There are some requirements: that the customer requires multiple parts from the same raw material and that the number required of each part number is the same quantity. In our experience using this strategy reduces the total overall costs by between 25-50%.
One of our customers had a requirement for 3 small parts to be die cut manufactured using a 3M VHB (Very High Bond) adhesive tape. 3M VHB tape is very expensive and has an exteremly high MOQ. Using our maximum yield strategy we were able to make a die with the 3 parts nested together which resulted in a price to the customer at 60% it would have cost using qty 3 dies of each of the 3 parts individually, see photo.

A few weeks ago we were asked by a potential new customer if we could cut Fabric. This is a common question and one i always tend to worry about because the answer is always "it depends". The variable inputs include how firm the fabric is, whats the thickness of the fabric and how detailed the cuts need to be. Also, there is always a "surprise" with cutting fabric - something that crops up unexpected.
This customer www.fleeceworks.com wanted a series of parts making using the same fabric but with different designs and different material thicknesses. We and the customer were up for the challenge to see if Die Cutting was the best option to manufacture the parts. There were 3 different parts using 3 different thicknesses (1/4", 1/2", 3/4") of Fabric that were required.
We met with the customer and had a few discussions of how to produce the best service in terms of optimizing the material yield while still keeping the unit cost as low as possible. The surprise was that the Fabric arrived at the shop in large quantities in 60" widths and in lengths up to 72 feet - a challenge of handling and storage. But, we have a very "get the job done" attitude" and so we spent time before taking the best action.
Our solution was to make 1 die of the 2 similar design parts "nested" together on a 4 up die so that every time we hit the die we made 4 parts. The other larger part was put on another die using common rule to minimize the material being used. We succeeded in producing the best possible yield at the lowest possible cost.
The lesson we learned is that Die Cutting Fabric is very possible but "it all depends".
