The single punch tablet pressing machine transforms powder or granular raw materials into precisely formed tablets ranging from 5-10mm in diameter. This versatile equipment can produce round, cylindrical tablets as well as custom-shaped tablets with text, trademarks, or patterns. With adjustable tablet weight, thickness, and hardness parameters, this machine offers exceptional flexibility for various production needs.
This tablet press finds extensive application across multiple industries including pharmaceuticals (both Western and traditional Chinese medicine tablets), food production (candy chips, coffee tablets), healthcare products (calcium tablets, propolis tablets), and chemical manufacturing (mothballs, catalysts). The machine demonstrates excellent material adaptability, particularly for non-adhesive powders.
Key operational features include both electric and manual pressing options, producing 3500-4000 tablets per hour in electric mode. The machine maintains consistent tablet quality with smooth surfaces and uniform weight distribution. Remarkably efficient, it requires only 200 grams of material for experimental batches, minimizing raw material waste.
The robust construction features a cast iron body with high-hardness steel molds, ensuring durability and long service life. Operation requires minimal training, with most staff able to master basic functions quickly. Custom molds between 5-10mm can be manufactured to meet specific product requirements.
For optimal tablet production, materials should possess three essential characteristics: good fluidity for consistent filling, proper compression formability to prevent defects, and adequate lubrication to prevent sticking. While many applications require granulation prior to pressing, recent advancements in excipient technology have expanded direct powder compression possibilities.
Common tablet quality issues and solutions include: adjusting pressure or adhesives for loose tablets, modifying formulations or equipment settings for capping problems, controlling moisture content and lubrication for sticking issues, and optimizing disintegrant ratios for delayed dissolution. Regular quality checks during production ensure consistent output.
The machine's installation requires a stable work surface approximately 600mm high, with proper anchoring and electrical connections. Die assembly follows a specific sequence (lower die → middle die → bench plate → upper die → hopper) with careful attention to alignment to prevent friction or collision during operation.
Critical adjustments include tablet thickness (via lower punch alignment), filling depth (for weight control), and pressure settings (for hardness). Proper debugging involves test runs and gradual parameter optimization until desired tablet characteristics are achieved.
Operational safety requires attention to machine rotation direction, proper belt tensioning, and avoiding overloading. The upper punch should always be in the raised position before starting to prevent jamming. In case of machine stoppage, immediate power shutdown followed by careful troubleshooting prevents component damage.
Maintenance procedures include regular cleaning, lubrication according to manufacturer specifications, and periodic inspection of all moving parts. Proper die removal techniques prevent damage to precision components. When not in use, machines should be protected from dust and moisture.
