In tablet compression machines, tooling refers to the punches and dies used to form tablets by compressing powder or granules. The types of tooling are classified based on their design, size, and standards, which are tailored to specific machine requirements and tablet shapes. Below is a concise overview of the main types of tooling used in tablet compression machines:

Types of Tooling in Tablet Compression Machines:

1.Based on Industry Standards

a.B Tooling:Most common standard for tablet presses.Punch barrel diameter: ~19 mm.Die diameter: ~30.16 mm (standard) or ~24 mm (for smaller tablets).Used for medium-sized tablets (up to ~13 mm diameter or ~19 mm length for capsules).Subcategories:BB Tooling: Smaller die diameter (~24 mm) for smaller tablets.D Tooling: Larger punch barrel (25.4 mm) and die diameter (38.1 mm) for larger tablets (up to ~25 mm diameter or ~28 mm length).

b.EU Tooling:Conforms to European standards (e.g., EU1, EU19).Similar to B and D but with metric dimensions and specific tolerances.Often used in European-manufactured tablet presses.

c.TSM Tooling:Follows Tablet Specification Manual (TSM) standards, primarily used in North America.Compatible with B and D tooling but with specific dimensional requirements.

2.Based on Punch and Die Design

a.Standard Tooling:Used for simple, round tablets with flat or concave surfaces.Basic punch tip shapes: flat, shallow concave, or deep concave.

b.Multi-Tip Tooling:Punches with multiple tips to produce several smaller tablets (e.g., mini-tablets) in a single compression cycle.Increases production efficiency for high-volume, small-dose tablets.

c.Shaped Tooling:Designed for non-round tablets (e.g., oval, capsule-shaped, triangular, or custom shapes like logos).Requires precise alignment to prevent tablet defects.

d.Core Rod Tooling:Used for tablets with a central hole (e.g., for controlled-release formulations).

Includes a rod in the die to create the hole during compression.

3.Based on Machine Compatibility

a.Single-Station Tooling:Used in single-station (or single-punch) presses, typically for small-scale or lab production.Simple design, often limited to standard shapes.

b.Rotary Tooling:Designed for high-speed rotary tablet presses.Multiple punches and dies (e.g., 16–100 stations) for mass production.Examples: B, D, or EU tooling adapted for rotary machines.

c.Fette or Kilian Tooling:Proprietary tooling for specific brands of tablet presses (e.g., Fette, Kilian).May have unique dimensions or keying systems for compatibility.

4.Based on Application

a.Standard Compression Tooling:For general pharmaceutical or nutraceutical tablets.Focuses on uniform compression and tablet hardness.

b.Effervescent Tooling:Designed for effervescent tablets, which require gentle compression to avoid damaging delicate formulations.Often uses larger dies and specialized punch tips.

c.Chewable or Orally Disintegrating Tooling:Optimized for softer or faster-dissolving tablets, with specific punch profiles to control density.

d.Coated Tooling:Punches with polished or coated surfaces (e.g., chrome, titanium nitride) to reduce sticking and improve tablet release, especially for sticky formulations.
