Dust cups are used to seal the area around the punch head, preventing powder from entering the die table and punch guide areas. This reduces contamination and helps protect tooling.
Are dust cups necessary for tablet press operation?
They’re not required to operate the press, but they’re strongly recommended. Dust cups help reduce wear, extend tooling life, and cut down on cleaning time.
Which tablet press tooling sizes do LFA dust cups support?
LFA dust cups are compatible with B tooling, D tooling, and 1-1/4" punches. They’re made to match OEM punch dimensions.
What are LFA dust cups made of?
Our dust cups are made from FDA-compliant, pharmaceutical-grade materials that are tear-resistant, chemical-resistant, and flexible enough for easy installation and removal.
How do I install or replace dust cups?
Dust cups are easy to install manually—just slide them over the punch head. No special tools or press modifications are needed. Replacing them is just as simple.
How often should I replace dust cups?
Check them regularly for signs of tearing, cracking, or loss of shape. Replacement intervals depend on production volume and material abrasiveness.
Can I use dust cups with both upper and lower punches?
Yes. LFA dust cups are designed for both upper and lower punch applications, depending on your press configuration.
