Dear Sir,
We Have An Immense Pleasure To Introduce Ourselves That
ACE INTERNATIONAL is One of the Leading Manufacturer & Exporter of
Pharmaceutical Machinery Tablet Tooling can be defined as tools to craft a particular
shape. Tableting tools i.e., Punches and dies are essential tools to shape any granules
into a solid dosage form by applying compaction force in a compression machine. Any
shape be it round, capsule, animal shape, bullet shape or any special shape can be
obtained with the help of the standard tooling. Now a very common question is what
are types of tooling and what tools shall be opted for the required dosage form. Before
understanding these parts, let’s go through some basics of tooling.
ACE INTERNATIONAL Is The Result Of A Unique Combination Of A Strong
Management Team Who Leads By The Vision To Establish The Company That Can
Provide Unique Specialized Services To Satisfy All Clients. It's Our Endeavour To Be
One Of The MostCompetitive Companies In The Pharma Industry With Emphasis On
Efficiency In Operations, Reliability For Clients & Thrust On Total Customer
Satisfaction.
We Got State Of The Art Manufacturing Facility Of More Than 5,000 Square Feet
Area With Over 100+ Dedicated Workforces Including High Qualified Engineers,
High Skilled Technicians & Experienced Professionals. We Have An Advanced HiTech Engineering Tool Room Setup & Haas Automation Inc. (USA) Make
CNC Workshop With Latest Imported Measuring Instruments.
Basic Features
Head: Head which rests on the cam, moves on cam during a compression.
Head Flat: Head flatness is vital and it’s size varies depending on tooling types.
Compression rollers in a compression machine press this head flat and that’s
whereactual compaction takes place.
Head Chamfer: Head chamfer is provided to remove the sharp edges for
smoothoperation in cam.
Head Degree: Head degree facilitates smooth movement in cam.
Neck: Its acts as supporting part for head and body for fitment and allows easy
movement in the punch bore.
Neck to Head Radius: This radius helps tools for easy fitment and avoid any sharp
corners which can wear out turret surface.
Neck to Barrel Radius: This radius assist tools for easy fitment and avoid any
sharpcorners which can wear out turret bore.
Barrel Chamfer: It facilitates to avoid any damage to turret bore.
Tip Undercut: Tip undercut acts as a scraper blade for die bore to remove the
stickygranules.
Tip Radius: Tip radius offers strength to tip during compression as tip need to
travelto a particular length in Die bore.
Barrel or Body: This part of the tool is used for fitment and sliding in the punch
bore.
Key: Key is used mostly in the upper punch for aligning the upper punch tip
with respect to die and avoids any kind of rotation during compression to
prevent majoraccidents.
Groove: The grooves are designed such that dust cup can be fitted to avoid the
contamination of any foreign particles coming from upper punch turret bore.
Tip Length: Tep length defines the penetration point of the tip inside the die bore.
Tip: Tips is your actual tablet size and its cavity provides shape to the tablet during
compression.
Cavity: Cavity is the area where the powder gets filled to form a shape during
compression.
Die height: Die height is defined as per the die plate bore slot thickness.
Die O.D.(Outer diameter): Die OD is the die bore slot in die plate.
Die Groove: This is the slot where the die lock screw is fixed.
Die O.D.(Outer Dia chamfer): This chamfer reduces sharp edges which can wear
andtear die bore surface.
Die I.D.(Inner dia chamfer): This chamfer minimizes the damages of die bore
surfaceand easy movement of punches inside the dies.
Tooling Set
A single tooling set comprises of upper punch, lower punch and die. These
punchesmove vertically in turret bores through cams and compress to
form a tablet. As per international standards, i.e. TSM (Tablet
Specification Manual) and EU
(Euro Standard), tooling specs have been standardized so that inventories
worldwide can be minimized for tablet presses. All international
manufacturers follow EU standards and TSM standards mostly followed
in the United States of America and inJapan.
Upper punch: Upper punch is fitted in the turret bore and moves
vertically in bores during compression. Upper punches make the upper
cavity of the tablet. It is fitted with key for alignment with die bore in case
of shape punches. For round punches, there is no need of key in upper
punches. Upper Punches travels 5-6mm inside the die bore during
compression and as per the penetration setting done in a compression
machine. Tip Length is shorter in the upper punch compared to the lower
punch. Tip length of upper punch is generally 8mm-9mm.
Lower punch: The lower punch is fitted in the turret bore and makes the
lower cavityof the tablet during compression. Lower punch tip always
stays inside the die bore hence there is no need of key in case of lower
punch. Tip length is relatively longer in the lower punch as it has to cover
the entire height of die and eject the tablet. The lower punch tip length is
25-28mm.
Die: Die is fitted in the die plate. Die bore in die is actually where the filling
of powderis done. Upper punch tip and lower punch tip compresses the
powder in the die bore with the help of compression roller pressure applied
on the head flat during compression to make the required shape of the
tablet.
Tooling Types
There are different types of tooling i.e. D, DB, B and BB types. Apart
from these standard types, there are FS tooling, BBS tooling, A
tooling and Chinese standardtools which are totally different than
International standard tools
