Tablet Press Punch and Die
What is Tablet Press Punch and Die?
Tablet press die is used to manufacture tablets, vitamin tablets, candy and other solid dosage forms forming tools. The main function of punch and die is to press and shape the powder after granulation, so that the powder particles are closely combined together to achieve a certain density and shape. By pressing and forming the die of the tablet press, various flake, block, ball and shaped products with certain fastness and stability can be produced. It is very common in the pharmaceutical industry and the food industry. These molds are usually made of high-hardness, corrosion-resistant materials, such as stainless steel or special alloys, to ensure long-term use without deformation and damage.
Structure of tablet die punch
1. Punches: Divided into upper punches and lower punches, they apply pressure to the material from above and below, respectively, to compress the material into the desired shape.
2. Die ring (Die) : A round hole used to hold the material and form the shape of the final product. The size of the die ring determines the diameter of the tablet.
3. Guide post and guide sleeve: Ensure the accurate alignment of the punch when moving up and down to avoid product quality problems caused by deviation.

The key points of selecting a precision punch and die
Lorem ipsum dolor sit amet consectetur adipisicing elit.
Identify production needs
- Product Specifications: Determine the shape, size, thickness and weight of the product to be pressed. Different product specifications may require different types of molds.
- Production capacity: Considering the capacity requirements of the production line, choose the mold suitable for high output or small batch production.
- Special requirements: If there are special requirements such as lettering, engraving, coating, etc., the corresponding mold type needs to be selected.
Identify die material
- Alloy steel: suitable for most conventional production, with good wear resistance and impact resistance.
- Carbide: Suitable for high-yield and high-strength production environments, with higher hardness and wear resistance.
- Ceramic material: suitable for special occasions with high temperature and corrosion resistance.
- Chrome plating, titanium plating: the surface treatment can improve the wear resistance and corrosion resistance of the mold.
Identify die size
- Punch diameter: Select the appropriate punch diameter according to product specifications.
- Die ring aperture: Make sure the die ring aperture matches the product diameter.
- Installation size: Confirm the compatibility between the installation size of the mold and the tablet press.
Identify die shape
- Round mold: Suitable for standard round tablets.
- Special-shaped mold: suitable for polygon or curved tablets of special shape.
- Shallow concave mold: suitable for double convex tablets.
- Deep concave die: chip suitable for coating tablets.
- Bevelled mold: suitable for bevelled tablets.
- Engraving mold: Engraved on the surface of the pill drug name, dosage and other information.
- Engraving mold: The tablet surface is engraved with a dividing line, easy to take in half.
Prepare spare molds
It is recommended to reserve some spare molds according to production requirements to cope with emergencies.
The key points of maintenance the punch and die tool
Keep it clean: Clean the surface and inside of the mold regularly to remove residue and dirt and prevent mold corrosion and damage.
Regular inspection: regularly check the wear and match accuracy of the mold, timely replace the parts with serious wear, and ensure the normal use of the mold.
Correct use: When using the mold, the operating procedures and safety norms should be observed to avoid overload use and improper operation leading to mold damage.
Before using the tablet press, check whether the mold specifications meet the required specifications. Install it before the mold, wipe it with a clean cloth and then install it. During the installation process, pay attention to check whether it matches the mold, handle it gently, and do not mix old and new molds.
After using the mold, immediately clean and check the mold for any damage, if any damage should be immediately screened and repaired.
If the mold is not used for a long time after cleaning, it must be coated with anti-rust oil. During the storage process, clear identification must be set according to the setting area of the machine type and the film type.
In the storage process, the temperature and humidity of the room can be maintained, so that the mold does not rust. If the room area is too large, you can open the lid to dry it and keep the mold room clean and dry.
