If you have broken a plunger or just need a spare you can order them here, We stock the smaller one as they are the most commonly overloaded. If you need something else or bigger then please email us or complete the quote form.
Plungers break when they are overloaded, not inserted correctly or aligned with the pressing surfaces. The most common is when they are overloaded and this is particularly true with the smaller ones where a few pumps of the hydraulic press handle can lead to very high stresses on small-cross sectional area of the plunger.
We have tested our plungers and made 1000s of them. Please don't push the limits and please use within the recommended limits on the product page. If you are using enough force to break high strength heat treated steel, This is more than enough to compress powders together.
You you are using high pressing forces then please check out or low profile die sets.
