Tablet-Punch & Tablet-Die


We offer Turn-Key gauging systems for Tablet-Punch & Tablet-Die Inspection.

I.SYSTEM DESCRIPTION

a.Tablet-Punch Gauging systems
We offer 3 gauging system configurations, as below:
Tablet-Punch : Fixture 1
Concentricity, Diameter & Total Length Measurement Fixture:
The Punch is loaded on the Fixture with its Body Diameter resting on a V-Block & its Head resting against a stopper.
The Operator activates a Foot-Switch.
This is the Measurement Cycle start.
For Concentricity measurement, the Punch is rotated on the V-Block to collect data for the circumference of its Head & punch Tip.
Tablet-Punch : Fixture 2
Capsule Fixture:
This is used for measurement of Oval Diameters.
Tablet-Punch : Fixture 3
Cup Depth Measurement Fixture:
Cup Depth Measurement is done by loading the Punch on the Gauge & then clamping it with a Toggle-Clamp.
Thus, the Parameters measured by the above three configurations are:
No. Parameters of the Tablet-Punch Punch-Gauging System / Fixture Number
1. Total length 1
2. Round Tip-Diameter, and Minor Tip-Diameter for Oval shape
3. Body Diameter at 2 locations
4. Tip concentricity w.r.t. Body Diameter
5. Head Diameter
6. Working length
7. Major Diameter for Oval shape 2
8. Cup Depth 3
Consider change-over Tooling to be applicable only for B-Type & D-Type Punches.
b.Tablet-Die Gauging systems
We offer 3 gauging system configurations, as below:
Tablet-Die : Fixture 1
Concentricity, Diameter & Total Length Measurement Fixture:
The Die is loaded in a Mandrel Guide.
The Operator then activates a Foot-Switch to start the Measurement Cycle.
For measuring Concentricity, the Die is rotated.
Data is collected for the Inner Diameter, Outer Diameter, and the Concentricity.
Tablet-Die : Fixture 2
Capsule Fixture:
This is used for measurement of Oval, and Oblong Diameters.
Tablet-Die : Fixture 3
Cup Depth Measurement Fixture:
Cup-Depth Measurement is done by loading the Die on a V-Block along the Die’s Thickness.
Thus, the Parameters measured by the above three configurations are:
No. Parameters of the Tablet-Die Die-Gauging System / Fixture Number
1. Die Outer-Diameter 1
2. Die Inner-Diameter (range 6 mm to ~24 mm)
3. Die Concentricity (Inner-Diameter /Outer-Diameter)
4. Inner-Diameter & Outer-Diameter Taper
5. Major-Diameter for Oval Shape 2
6. Die Thickness 3
7. Parallelism
Consider change-over Tooling to be applicable only for B-Type & D-Type Punches.

III.Advantages of our Compression Tooling Gauging Systems

  • ENSURE ACCURATE INSPECTIONS & REDUCE CYCLE TIMES
    An Easy & Well-defined Inspection Cycle is available for our Punch & Die Gauging systems. Part Loading, Data Collection & Unloading are the only tasks to be performed by the Operator. Once the Data is stored, the Gauging system generates all relevant Reports. It takes less than 10 seconds to check one Punch or Die.
  • IMPROVE PRODUCT QUALITY
    Gauge Least Count is 0.1 µm. The Repeatability is < 1 µm. This ensures that Dimensions with close Tolerances can be checked with a very high accuracy. Also, the Operator influence on measurement cycle becomes negligible, resulting in an overall improved Quality of Compression Tooling.
  • DECREASE DOWNTIME & MAINTENANCE COST
    An automated approach eliminates the need for traditional time-consuming, inaccurate, and costly inspection procedures. It also prevents press downtime during inspection, and also the critical dimensions are automatically recorded.
  • IMPROVE RECORD KEEPING
    All Inspection data is stored in Microsoft Access (or Microsoft SQL Server) Database. This helps maintain Historical data for years.
  • TOOL MATCHING REPORT
    Matching the longest length of upper Punch with the shortest length of lower Punch, can be used to minimize the deviation of tablet thickness and hardness. The Average working length of Combined Upper/Lower Punches can be made constant across Press Stations on a Turret.
