Tooling used in tablet punching

Tooling used in tablet punching

Which are list of five important commonly used toolings in the pharmaceutical industry?

D tooling, B tooling,  B B tooling,  D B tooling and

BBS tooling.


What are the different tooling dimensions in the pharmaceutical industry?

type of tooling, punch length, barrel diameter, dye diameter,height of dyes and maximum tablet size formed with.


What is different between TSM tooling and U tooling?

American Standard is also known as TSM Standard.

It is the sole reference on US manufacturing standards for tablets and tablet tooling, whereas

European Standard is also known as EU or UNOM Standard.

The EU standard is the most common tooling configuration used outside the USA.


What is commonly used MOC for punch and dye?

OH&S is oil hard and non shrinkable steel is commonly used for punches, whereas HCHC

that is high carbon, high chromium steel is commonly used for dyes.


What should be the replacement frequency for punches and dyes?

Replacement of punches and dyes depends on the size of wear.

Depending on the usage and wear patterns, punches may need to be replaced every one lakh to five lakh tablet compression cycles.

Dyes are typically having longer lifespan compared to punches.

Replacement frequency of punches and dyes depends on production volume, material characteristics,Tablet design and equipment maintenance.

For the punch inspection should be carried out.

5 ways that should be covered under the punch inspection procedure.

These are first visual inspection, second dimensional inspection, third wear and corrosion check,fourth functionality check and fifth documentation.


What are the consequences of damages of punches or dyes during compression?

There are the 6 important consequences of damages of punches or dyes during compression.

These are first product defects, second increased rejection rates, third loss of productivity,

fourth contamination risk, fifth machine wear and sixth very important regulatory non-compliance.


Why polishing of punches and dyes is required?

 5 reasons for polishing of punches and dyes.

One of the important reasons is polishing ensures smooth surfaces, reducing friction

and sticking.

Second important reason is polishing extend tooling lifespan by reducing wear and tear.


Same punches and dyes for different


same punches and dyes for different products is generally not recommended due to the risk of cross contamination and compromised product quality.


What is TSM in tablet tooling?

TSM, that is tooling specification manual, is the manual written by the American Pharmaceutical


The tabulating specification manual, that is TSM, is the most valuable source of tooling

information available.

What are the different type of punch tips?

There are the 6 different type of punch tips that are very commonly used in the pharmaceutical


First, flat-faced with bevel edges, second shallow concave, third standard concave, fourth deep

concave, fifth extra deep and sixth modified ball.


Which oil is commonly used for storage of punches and dyes in pharmaceutical industry?

Foodware mineral oil or white oil is commonly used for punch and dyes storage.

It gives protective coating, prevents corrosion and maintenance tooling integrity.


What are the advantages and disadvantages of using BB tooling?

BB-tooling is the short form for bolus booster tooling.

BB-tooling offers numerous advantages in terms of precision, durability, versatility,

efficiency and ease of maintenance.

It also comes with considerations such as initial cost, lead time, wear, cleaning challenges

and storage requirements.

Expand the role of tablet tooling coatings in improving tooling quality.

Tablet tooling coatings like hard chrome, diamond-like carbon or ceramic enhance the

durability, reduce wear and improve tablet quality by reducing friction, enhancing hardness

and improving release properties.

Which are the commonly done coatings for punches and dyes, titanium nitride, titanium carbon

nitride, diamond-like carbon, chromium nitride and aluminum chromium nitride are the commonly done coatings for punches and dyes.


What are the different parts of punch and issues?

You can refer below table for different parts of punch the description and use.

Punch head forms the upper surface of the tablet, whereas punch body supports the punch head

and tip.

Punch tip determines the shape and size of the tablet and other important parts are punch

shank, kiwi, taper, cup depth and cup diameter.


What is different between lower punch and upper punch?

difference between lower punch and upper punch.

The position of lower punch is below the die cavity during compression whereas position

of upper punch is above the die cavity during compression.

The function of lower punch is to support the tablet during compression and ejection whereas

the function of upper punch is to compress the powder or granules into the tablet form.

Tablet tooling taper is a slight angle on punch and die surfaces.

You can refer the diagram on a screen which is for TSM standard taper die.

It prevents tablet sticking by helping tablets release smoothly during compression process.


What should be the frequency for inspection of tooling?

Below three frequencies can be followed for inspection of tooling.

First frequency when punch head is newly received at side.

Second frequency that is after completion of tablet’s compression cycle.

Set regular maintenance intervals for example every 100 million tablets with a tolerance

of plus or minus 5 million tablets.

Third frequency whenever variation in tablet appearance is observed.


What cleaning and storage procedure is followed for punch and die was the punch and dies in

water and drive with a lint free cloth.

Clean and dry to remove all production residues.

Ultrasonic cleaning procedure is one of the recommended procedure for the cleaning of punch

and die.

Lubricate punch and dies before storing to prevent corrosion and rust.


Who are the India’s largest suppliers for punch and die?

Karnawati Engineering Limited, Riddhi Pharma Machinery Limited, Gansons Limited, JMP Technical

Solutions Private Limited, Path Engineering and Consultant are the India’s largest suppliers

for punch and dies.


Who are the world’s leading suppliers for punch and dies?

Ima Killian, Coach Elizabeth Companies, Natural Engineering Company and Fatay Compacting are

world’s leading suppliers for punch and dies.


 which guidelines are commonly referred for punch and dies in

the pharmaceutical industry?

Answer it, USP, European Pharmacopia, ISO, JMP and ISP guidelines are commonly referred for

punch and dies in pharmaceutical industry.
