Prevent contamination in your dust cup grooves…

Now, you can keep oil and debris out of your granulation with Natoli’s dust cups.

We highly recommend using dust cups with your punches. While they are an optional accessory, their benefit far outweighs their price. You’ll also be able to interchange and reuse.Dust Cup Grooves

Dust cups will:

  • Provide a secondary barrier to the upper punch seals
  • Prevent oil and other debris from contaminating granulation
  • Ensure production runs smoothly and cut back on cleaning time

Dust cups are especially important when you’re using segmented turrets & in situations where there are clearance issues. So, what kind of dust cup do you need?


Dust Cups & Bellows

Barrel-Style vs. Standard Dust Cups

Dust cups are made in a variety of sizes but come in two different styles: barrel-style and standard.

Standard Dust Cups

Standard dust cups require a little extra work. You’ll manually cut out a hole using the upper punch, and then fit the dust cup directly to the upper punch tip.

Barrel-Style Dust Cups

Barrel-style dust cups come with pre-cut holes that were cut to fit directly on your punch barrels. You can use them with or without upper punch dust cup grooves.

All our dust cups are made with FDA compliant pharmaceutical-grade materials that are specifically selected for their:

  • Stability
  • Wear-resistance
  • Cleaning
  • Flexibility

Natoli also manufactures bellows with the same pharmaceutical-grade materials. These bellows will prevent lubricant contamination and black specks on your tablets.

The training, factory staff and instruction completely exceeded all expectations. I would come back anytime; easily one of the Top 10, if not Top 5, companies I have visited with. I spoke with Dale about what a great company Natoli is.
