    3.What Is Tooling System In Tablet Compression Machine?

    The tooling system of tablet compression machine generally consists of an upper punch, a lower punch and a mold. These punches are moved vertically by cams in the turret bore and compressed to form tablets. They mainly determine the shape, size and quality of tablets.

    Upper Punch


    Upper Punch-sourced: hvax

    In all types of tablet compression machines, the upper punch is generally installed in the turret hole and moves vertically in the hole during the compression process. It generally forms the upper cavity of tablets and is used to align with the die hole in the case of a shape punch.

    Lower Punch


    Lower Punch-sourced: hvax

    The lower punch is also installed in the turret hole and causes the tablet to form a lower cavity during the compression process. The tip of the lower punch always remains in the die hole, and its tip length is relatively long, generally 25-28mm. Because it has to cover the entire height of the mold and eject the tablets.



    Molds-sourced: fuyimachinery

    The mold is generally installed on the template of your tablet compression machine. The die holes in the mold are actually where the powder is filled. By means of the up and down vertical movement of the upper and lower punches, the powder in the die hole is compressed into tablets of the desired shape and size.

    4.What Are The Different Tooling Systems For Types Of Tablet Compression Machine?


    Different Tooling Systems For Types Of Tablet Compression Machine-sourced: hvax

    Currently, the tooling systems for all types of tablet compression machines used in tablet manufacturing in the world are mainly divided into type D, type B, type DB, and type BB.

    D Tooling

    The barrel diameter of the D tooling is 25.4 mm and the mold diameter is 38.10 mm. It is suitable for your tablets with a maximum length or diameter of 25.4 mm. Compared to the B tooling system, the punches and dies of the D usually have larger punch diameters. This makes D type more suitable for large size tablet compression.

    DB Tooling

    The DB tooling system has a barrel diameter of 0.75 inches, a length of 5.25 inches, a head diameter of 1 inch, and a mold outer diameter of 30.16 mm. When D tooling system is used on the tablet compression machine of class B tooling system, DB tooling system is formed.

    B Tooling

    The punch diameter of the B tooling system is 30.16 mm (1.1875 inches), suitable for all tablet sizes as well as the largest size of the B punch. Compared with D tooling system, the output of B tooling system will be 20% to 25% higher than D type.

    BB Tooling

    The smaller BB tooling system has a die diameter of 24 mm (0.945 in). This type of mold is suitable for tablets with a diameter of 9 mm or up to 11 mm.

    Classification of tooling system on the basis of there sizes in the table below:

    Tooling Types Punch Barrel Diameter(mm) Punch Head Diameter(inch) Outer Diameter of Die(mm) Length(inch)
    D 25.4mm 1.25 38.10mm 5.25
    B 19.0mm 1 30.16mm 5.25
    BB 19.0mm 1 24.00mm 5.25
    DB 25.4mm 1 30.16mm 5.25

    The tooling system for different types of tablet compression machine:

      Single Punch Tablet Compression Machine Rotary Tablet Compression Machine
    Tooling Type TDP

    5.What Are The Suitable Materials Of Tooling System For Types Of Tablet Compression Machine?

    The tooling system materials of punches and molds for your tablet compression machine shall conform with CGMP. The most suitable materials for your tooling system is stainless steel. The reasons are:



    Wear-resistant-sourced: bhagwatipharma

    Because of the special way tablet compression machine works, it requires longer and more durable punches and dies. With strong wear resistance, the stainless steel is extremely compressible. This prevents your molds from deforming during continuous compression.

    Strong Stability


    Strong Stability-sourced: bhagwatipharma

    Stainless steel helps maintain the stability of the tablet compression machine mold. Molds made of stainless steel will not wear out for a long time, thus avoiding a series of problems that occur during mass production.

    Good Preservative

    The raw materials used to produce the tablets are also important, so the tooling system materials used shall be away from contamination of your tablets. Stainless steel is not easily corroded, and punches and molds made with it will not cause material contamination of tablets.

    6.Why It Is Important To Standardize The Tooling System For Types Of Tablet Compression Machine?

    Calls for merging tooling systems for types of tablet compression machines have become increasingly widespread. To standardize the tooling system is important and can benefit you in the ways of:

    Enhance Tooling Interchangeability

    When tooling is unified, the costs of your standardized tooling production, inspection, packaging, procurement, operation and maintenance will be greatly reduced, and the corresponding standardized inspection process will also be simplified.

    Improve Global Cooperation


    Improve Global Cooperation-sourced: eliz

    When a globally unified tooling system is accepted by tablet press developers, the quality and grade of tooling will be consistent across all pharmaceutical products and plants. This will greatly enhance your technical exchanges, problem solving and development of global tablet compression machines.

    7.What Are The Treating And Coating Tooling For Types Of Tablet Compression Machine?

    During your tablet manufacturing process from all types of tablet compression machines, there may be some problems such as sticking and picking up. Polishing and coating tooling for the punches are the most common methods.

    Diamond Coating


    Diamond Coating-sourced:aimspharmaengineering

    Applying diamond coatings into punch and die systems can greatly improve the durability of your punch and die systems. This method can greatly reduce the stickiness during your tablet compression. This is more suitable for tablet compression machines for effervescent tablets.

    Chrome Electroplating


    Chrome Electroplating-sourced:tincoat

    Chrome electroplating is available on most standard tablet compression machine. This coating is typically 5 microns. Another technique almost similar to electroplating chrome processing is Physical Vapor Deposition (PVD). This treatment protects your tablet press tooling system from wear and ensures better stability.

    Chromium Nitride Coating


    Chromium Nitride Coating-sourced:pharmaceuticalmanufacturer

    Chromium nitride coating is an extremely hard, inert thin film coating. It is superior to electroplating and has higher temperature resistance, making it ideal for high temperature environments. It is cost-effective and provides enhanced wear protection for your tooling systems.

    Aluminum-titanium Nitride or Titanium Nitride Coating


    Titanium Nitride Coating-sourced:jaiengineering

    Aluminum-titanium nitride or titanium nitride coating is a thin film coating developed from titanium nitride and is known for its smooth surface and high surface hardness. It has higher temperature resistance and slightly higher hardness, especially higher thermal hardness. It is the best choice for most tablet compression machines.

    8.What Are The Differences Between EU And TSM Tooling System Standards For Types Of Tablet Compression Machine?

    The EU tooling system and TSM tooling system are two different tablet press punch and die specifications for different location application. There are two standard punch and die designs to consider when you plan to invest in new tablet press tooling for all types of tablet compression machine:

      EU Tooling System TSM Tooling System
