Single Punch Tablet Press Machine
Product Overview
The DP12 model is suitable for smaller tablets up to 12 mm diameter, while the DP25 model supports tablets up to 25 mm diameter, making both models suitable for pharmaceutical laboratories, food research, chemical testing, and pilot-scale tablet development.
Definition
The Single Punch Tablet Press DP12/DP25, manufactured by Sinoped, is a compact laboratory tablet press machine designed for pharmaceutical research, small-batch tablet production, and material compression testing. It is mainly used to compress powder and granular raw materials into tablets with controlled diameter, thickness, and hardness.
Compared with high-speed rotary tablet presses used for large-scale manufacturing, the single punch tablet compression machine provides greater flexibility for formulation development, pilot testing, and laboratory applications. Its adjustable filling depth and tablet thickness make it suitable for different tablet formulations in pharmaceutical, chemical, food, electronics, and research industries.
The DP12/DP25 tablet press combines a stable mechanical structure with easy operation, making it a practical solution for companies and laboratories that require a reliable tablet making machine for R&D and small production environments.
How It Works
The single punch tablet press machine uses a mechanical compression principle to transform powder or granulated materials into solid tablets. During operation, the material enters the die cavity, and the upper and lower punches apply controlled compression force to form tablets with consistent dimensions.
The filling depth determines the amount of material loaded into the die cavity, while the compression system controls tablet density and thickness. After compression, the lower punch moves upward to release the finished tablet.
Sinoped DP12/DP25 adopts a four-column structure and integrated transmission system, which improves mechanical stability during operation and helps reduce vibration and operating noise. The adjustable compression parameters allow users to optimize tablet quality according to different formulations and production requirements.

Product Selection Guide
Selecting a suitable laboratory tablet press machine mainly depends on tablet diameter requirements, formulation characteristics, and application scale.
The DP-12 single punch tablet press is designed for smaller tablet production and laboratory testing. With a maximum tablet diameter of 12 mm, it is suitable for pharmaceutical formulation experiments, material testing, and prototype tablet preparation where compact equipment and flexible operation are required.
The DP-25 tablet compression machine provides a larger compression range with a maximum tablet diameter of 25 mm. It is commonly selected for applications involving larger tablet formats, pilot-scale testing, and pharmaceutical development projects that require broader formulation flexibility.
Both models provide a maximum compression force of 50 kN and adjustable tablet thickness and filling depth, allowing users to evaluate different tablet formulations before transferring processes to industrial tablet production lines.

Installation & Maintenance
Proper installation and regular maintenance are important for maintaining stable tablet quality and extending equipment service life.
The single punch tablet press machine should be installed on a stable and level surface with appropriate electrical connection and sufficient operating space. Before operation, users should check the lubrication condition, punch and die installation, and ensure that the compression chamber is clean.
During daily operation, residual powder should be removed after production. Punches, dies, transmission components, and electrical systems should be inspected regularly according to operating frequency. Proper lubrication and timely replacement of worn components help maintain compression accuracy and operational stability.
Industry Standards and Compliance
The Sinoped DP12/DP25 pharmaceutical tablet press machine is designed according to general requirements for pharmaceutical and industrial equipment manufacturing.
Depending on the application environment and destination market, tablet compression equipment may need to consider relevant standards and requirements, including:
| Standard / Guideline | Application |
| GMP (Good Manufacturing Practice) | Pharmaceutical production environment requirements |
