Description
Technical Parameters
Tablet press punches and dies are key components used in tablet presses to compress drug powders or particles into fixed shapes and sizes of tablets. Punches are usually divided into upper punch and lower punch, which move relative to each other under the pressure of the tablet press, compressing the material into the dies to form tablets.
The mold is a hole with a specific shape and size, used to define the final form of the tablet. In the pharmaceutical industry, tablets, as one of the main dosage forms of drugs, cannot be produced without the key equipment - tablet press. The core components of the tablet press, namely punches and dies, are the key factors determining the quality, shape, and size of the tablet.

Construction and Material:
As the core components of Tablet Press, the construction and design of Tablet press punches and dies are directly related to the production quality and efficiency of tablets.
● Construction of Punches
Die is one of the key components in a tablet press used to compress drug powder or particles into fixed shapes and sizes of tablets. It usually consists of the following parts:
(1) Punch Head:
The punch head is the working part of the die, which comes into direct contact with drug powder or particles and is compressed into tablets under the pressure of a tablet press. The shape and size of the punch determine the final shape and size of the tablet. To ensure the quality of the tablets, the punch is usually made using high-precision machining technology, with a smooth surface and no burrs.
(2) Punch Shank:
The punch is the part that connects the punch and other components of the tablet press, responsible for transmitting the movement of the punch to the drug powder or particles. Punch bars usually have high strength and stiffness to ensure that they do not bend or deform during the pressing process.
(3) Connecting components:
The punching die also needs to be connected to other parts of the tablet press through some connecting components (such as screws, pins, etc.). These connecting components need to have sufficient strength and reliability to ensure that they do not loosen or fall off during the pressing process.
● Construction of Dies
A mold is a component used in a tablet press to hold and shape pharmaceutical powders or particles, and its construction also has a significant impact on the quality of tablets. A mold usually consists of the following parts:
(1) Die cavity:
The die cavity is the core part of the mold, which matches the shape and size of the punch and is used to accommodate and shape pharmaceutical powders or particles. The inner wall of the mold hole needs to undergo special treatment to improve wear resistance and demolding performance, in order to reduce contamination and damage to the tablet. Meanwhile, the diameter and depth of the mold holes also need to be precisely controlled according to the requirements of the tablet.
(2) Die Holder:
The die holder is a component used to secure the mold, ensuring that the mold remains stable and stationary during the pressing process. The mold seat is usually made of high-strength materials to withstand the enormous pressure generated during the pressing process. At the same time, the fit between the mold seat and the mold also needs to be very tight to prevent drug powder or particles from leaking out from the gaps.
(3) Auxiliary components:
The mold may also include some auxiliary components, such as positioning pins, guide sleeves, etc. These components are used to ensure the correct installation and positioning of the mold in the tablet press, as well as to improve the service life and stability of the mold.
● Structural characteristics and requirements
The construction design of tablet press punches and dies needs to meet the following characteristics and requirements:
(1) High precision:
Due to the direct impact of the shape and size of the punch and mold on the quality and shape of the tablet, their machining accuracy requirements are very high. Usually, high-precision machining equipment such as CNC machines are used for processing to ensure the accuracy of their shape and dimensions.
(2) High strength and wear resistance:
During the pressing process, the die and mold need to withstand tremendous pressure and friction, so they must have high strength and wear resistance. Usually, materials with high hardness and wear resistance (such as hard alloys, ceramics, etc.) are used for manufacturing, and their performance is improved through processes such as heat treatment.
(3) Easy to replace and maintain:
In order to improve production efficiency and reduce maintenance costs, the design of dies and molds should be easy to replace and maintain. Typically, standardized and modular design methods are used to facilitate the disassembly and installation of stamping dies and molds.
(4) Cleanliness and hygiene:
Due to direct contact between molds and pharmaceutical powders or particles, it is necessary to maintain their cleanliness and hygiene. In the design and manufacturing process, factors that are easy to clean and disinfect need to be considered to prevent drug contamination and cross infection.
Main material types:
The material selection of tablet press punches and dies is crucial for the production quality, efficiency, and durability of the tablets. The following is a detailed explanation of common materials used in product:
● High Carbon Chromium Tool Steel
(1) Characteristics:
High carbon chromium tool steel is known for its high hardness, high wear resistance, and good toughness, making it very suitable for manufacturing components that need to withstand high pressure and frequent impacts, such as stamping dies and molds for tablet presses.
(2) Application:
In the manufacturing of product, high carbon chromium tool steel is often used to make key parts of punches and molds to ensure stable shape and size during the pressing process.
● High Speed Steel (HSS)
(1) Characteristics:
High speed steel has excellent red hardness and wear resistance, and can maintain high hardness and cutting performance even at high temperatures. This makes it an ideal material for manufacturing high-speed cutting tools and molds.
(2) Application:
In the manufacturing of product, high-speed steel is often used to make components that need to withstand high-speed impacts and high temperature environments, in order to improve the durability and production efficiency of molds.
● Carbide
(1) Characteristics:
Hard alloys are made from hard compounds of refractory metals and bonded metals through powder metallurgy technology, with extremely high hardness and wear resistance. It is currently one of the hardest known materials.
(2) Application:
Due to the high hardness and wear resistance of hard alloys, they are often used to manufacture tablet press punches and dies components that require extremely high wear resistance, especially when dealing with high hardness or high abrasive pharmaceutical powders.
● Ceramic
(1) Characteristics:
Ceramic materials have extremely high hardness, wear resistance, and chemical stability, as well as good corrosion resistance and insulation properties. However, its brittleness is relatively high, and attention should be paid to avoiding impact and collision during use.
(2) Application:
In specific situations, ceramic materials can also be used to manufacture certain components of product, such as mold holes. However, due to its high cost and difficulty in processing, its application scope is relatively limited.
