Selecting the right steel for each individual application is key to the successful performance of your tablet compression tooling. Good steel selection will achieve an optimum balance of the following properties:
Toughness
Abrasive wear resistance.
Adhesive wear resistance
High hardness levels
Compressive strength
Corrosion resistance
Good machinability and formability
Clean structure
All of our PharmaGrade® steels are ESR refined at no extra cost.
HPG-S (Standard)
Suitable for general-purpose applications.
FEATURES
Harder & more wear resistant compared to equivalent steels used for tablet tooling
Very high toughness properties
High strength profile
Good polish-ability (due to ESR process)
BENEFITS
Long tooling life
Resistant to fracture
Reduced tabletting problems (i.e. sticking etc)
APPLICATION
For standard application on punches. Especially deep cupped tips and complex shapes.
HPG-SS (Stainless Steel)
A great solution when corrosion resistance is a primary requirement.
FEATURES
Excellent corrosion-resistant properties
Good polish-ability (due to fine carbide structure)
Optimised for PharmaCote® products
Higher chrome content than HPG-S and HPG-P
BENEFITS
Extended tooling life when compressing corrosive formulations, using wash-in-place (WIP) systems, and/or using aggressive cleaning processes
APPLICATION
For punches and dies.
HPG-TC (Tungsten Carbide)
A sintered micro-grained tungsten carbide cemented with cobalt.
FEATURES
High compressive strength
Extremely high wear resistance insert
BENEFITS
Reduced die bore wear
Reduced die bore ringing
Good tooling life when compressing abrasive formulation
APPLICATION
Used for dies only.
Suitable for formulations that are particularly abrasive. Superior quality to other ‘premium’ steels available in the industry.
FEATURES
High wear resistance

Extremely high compressive strength
Reduced risk of formulation reacting to elements within the die material
BENEFITS
Reduces die bore wear
Reduces die bore ringing
No black marks on tablets
APPLICATION
A specialist solution for dies.
