A hydraulic-driven lab press optimized for high-density cosmetic powder compaction, featuring a dual-stage hydraulic pump that balances stable pressure output and efficient pressure buildup. Designed to address the unique challenges of compacting dense formulations (e.g., mineral foundations, waterproof bronzers) that require sustained pressure to avoid cracking or crumbling post-pressing. Its robust construction supports continuous 8-hour operation in lab environments, making it suitable for both iterative R&D testing and small-scale production of high-performance cosmetic powders.
Delivers pressure fluctuation ≤0.5MPa per 5 minutes, with a 100mm large-diameter piston that distributes pressure evenly across the powder surface—eliminating edge-to-center density variations common with smaller pistons. This even pressure distribution reduces the risk of post-pressing cracks, a major pain point for high-density formulations. Compared to smaller piston designs, it cuts pumping cycles by 60%, speeding up compaction without sacrificing stability.
The piston reciprocates to apply pressure during both upward and downward strokes, a key advantage for dense powders: this bidirectional action squeezes out trapped air from the powder bed, preventing voids that can cause product breakage. Operators can adjust the stroke speed (0.5-2mm/s) to match powder flowability, ensuring optimal compaction for low-flow mineral powders.
Offers manual and semi-automatic operating modes to suit diverse testing needs: manual mode for hands-on parameter adjustment during early-stage R&D, and semi-automatic mode with a 0-60 second adjustable pressure hold function. The pressure hold feature is critical for heat-sensitive ingredients (e.g., natural oils, active botanicals), as it allows for gentle, prolonged compaction without generating excess heat.
Built with a reinforced steel frame coated in anti-corrosion epoxy, resistant to chemical cleaners (e.g., isopropyl alcohol, lab disinfectants) commonly used in cosmetic labs. All hydraulic components are sealed with food-grade nitrile rubber to prevent oil leakage and ensure compliance with cosmetic safety standards. The press requires minimal lubrication, reducing maintenance downtime.
Specialized in compacting high-density cosmetic powders that require 18-24 tons of pressure, such as waterproof pressed foundations, long-wearing bronzers, and transfer-resistant face powders. The sustained hydraulic pressure ensures these products maintain structural integrity during shipping, handling, and daily use—addressing a top complaint from consumers of dense pressed products.
Enables comprehensive texture testing for long-wearing cosmetic products, including evaluations of powder adhesion (resistance to flaking), crack resistance (after 100+ opening/closing cycles), and oil absorption (to ensure color consistency after skin contact). These tests are critical for validating formulations before scaling to mass production.
Beyond cosmetics, it is compatible with pharmaceutical powders (e.g., oral disintegrating tablets) and ceramic materials, making it a versatile asset for labs with multi-disciplinary testing needs. For cosmetic-pharmaceutical hybrid products (e.g., SPF-infused pressed powders), it supports testing of both cosmetic texture and pharmaceutical ingredient stability.
Hydraulic models excel at sustained high pressure (18-24 tons) for dense compacts, making them ideal for formulations where structural integrity is prioritized. Servo-driven models, by contrast, offer finer pressure increments (0.01 tons) for delicate, low-density powders (e.g., translucent setting powders) where precision over maximum pressure is key. Hydraulic presses also have a higher peak load capacity (up to 30 tons) for occasional over-pressing tests.
The minimum sample size is 5g per press—critical for early-stage R&D, where raw materials (e.g., rare natural extracts, high-cost pigments) may be limited or expensive. This small sample size allows teams to test multiple formula variations with minimal material waste.
Routine maintenance is simple: monthly inspection of hydraulic oil level and clarity (oil should be replaced every 6 months or after 500 hours of operation) and annual replacement of hydraulic seals. No additional lubrication is needed, and the anti-corrosion frame requires only occasional wiping with a damp cloth—keeping maintenance costs low.
