With years of expertise in food & pharmaceutical lubrication and field visits to numerous health supplement and pharma factories, we identify carbon buildup and powder adhesion on rotary tablet press punch-and-die sets as the top costly pain point.
Conventional high-temperature greases degrade quickly under constant ~110°C operation, carbonizing and mixing with airborne fine drug/probiotic powder to form stubborn deposits inside die cavities. This causes tablets to develop permanent black spots and pits, rendering entire batches unqualified and wasting costly raw materials.
Severe Working Conditions
Rotary tablet press toolings run steadily at 110°C amid heavy ultrafine powder dust. Standard grease decomposes, blackens and hardens over time, forming carbon scale trapped between punches and dies. Flakes fall off during compression and contaminate tablets. Daily full disassembly, grinding and cleaning take over 2 hours, cutting productive runtime drastically. Persistent carbon deposits also accelerate tool wear, spiking frequent replacement costs.
These toolings face triple harsh conditions: sustained high heat, heavy medicinal dust, and periodic equipment washdown. Ordinary greases fail due to poor thermal stability, heavy coking and high powder adsorption. GMP-compliant, low-coking high-temperature grease is mandatory to cut tablet defects and downtime maintenance.
Solution: Baoxing BX-300/E (SG) NSF H1 Food-Grade PFPE High-Temperature Grease
Specially engineered for pharma/health supplement tablet press toolings:
1. NSF H1 certified for incidental food/drug contact; stable for continuous 130°C operation with minimal thermal decomposition & carbonization
2. Chemically inert base resists absorption of micro medicinal powder, eliminating die cavity coking at source
3. Waterproof and resistant to sanitization washdowns; intact protective oil film after cleaning for long-lasting punch/die protection
Proven Production Benefits
Factories switching to this grease report drastically lower tablet surface defect rates, an 80% reduction in tool disassembly & cleaning frequency, extended tool service life, and effortless GMP workshop audits. Universally compatible with all rotary tablet presses and dry granulation compression toolings. Single grease filling delivers long service intervals, slashing labor and consumable maintenance expenses.
High-value tablet raw materials make tool lubrication a critical cost-control link. Improper grease leads to persistent defective products and production halts. Replace coke-prone conventional greases with Baoxing BX-300/E (SG) high-temperature grease to lift tablet yield, stabilize output, and cut overall losses from raw material scrap and tool replacement.
