Precise Pressure Control: An analog pressure gauge (calibrated annually for accuracy) clearly displays pressure in 0-25 MPa, with a built-in conversion chart (e.g., 12 tons = 20 MPa, 8 tons = 13.3 MPa) to simplify pressure setting for different sample requirements.
Adequate Working Space: The 550*450*970mm compression chamber (with a maximum mold diameter of 80 mm) accommodates various mold sizes and shapes, including round (φ10-80 mm), square (10×10-50×50 mm), and rectangular molds (custom molds available upon request for special-shaped samples).
Manual Operation: An ergonomic hand lever (with a 1:10 force amplification ratio) requires minimal force (≤50 N) for pressure application, reducing operator fatigue during repeated use. The lever is equipped with a safety lock to prevent accidental pressure release during compaction.
Safety Protection: A built-in overload prevention valve automatically relieves pressure if it exceeds 25 MPa, avoiding damage to the hydraulic system or mold. The machine also has a protective cover (transparent acrylic) to prevent sample splashing during compaction.

The Laboratory Powder Press Machine is a versatile, bench-top device designed for cosmetic labs to press various powder formulations into testable samples. Unlike specialized presses (e.g., baking powder models), it supports multi-purpose use—from eye shadow and blush to foundation compacts—making it a cost-effective tool for R&D teams. Integrating manual and pneumatic operation modes, it balances precision and flexibility, allowing researchers to test pressing parameters (pressure, thickness, density) before scaling to industrial production. Its rugged construction and easy cleaning ensure compatibility with the fast-paced, multi-formula environment of cosmetic labs .
Wide Pressure Range: Offers adjustable pressure from 0-20T (0-28MPa) with a digital gauge accuracy of ±0.1MPa, enabling testing of delicate (e.g., loose blush) and dense (e.g., pressed foundation) formulations .
Flexible Sample Sizing: Accommodates mold diameters from 5mm to 25mm and adjustable tablet thickness up to 10mm, supporting standard sample sizes for texture, wear, and stability testing .
Dual Operation Options: The manual mode (hydraulic pump) is ideal for ultra-precise, small-batch sampling, while the pneumatic mode (6-8kg/cm² air supply) delivers 1,200 pieces/hour for larger trial runs .
GMP-Compliant Design: Constructed with anodized aluminum and SUS304 stainless steel, with a quick-release hopper that reduces cross-contamination risk. Cleaning between formulations takes only 8 minutes .
Formulation Development: Used to test powder blends (talc, mica, iron oxides) for pressing cohesion, ensuring samples maintain shape and texture under real-world use conditions .
Quality Control Sampling: Enables labs to replicate production-line pressed samples for batch-to-batch consistency checks, reducing industrial waste from formulation errors .
Student & Academic Research: Suitable for cosmetic science programs to teach powder pressing principles, with a lightweight (15kg) design ideal for classroom use .
Q: What is the minimum powder quantity needed per sample?
A: Only 3g of powder is required for a standard 15mm diameter sample—ideal for early-stage formulations where raw materials are limited .
Q: Can it press samples with embossed logos or patterns?
A: Yes. Custom molds with 2D/3D embossing are available, allowing labs to test brand-specific pressed designs without investing in industrial tooling .
Q: How does it differ from industrial powder presses?
A: While industrial presses prioritize speed (10,000+ pieces/hour), this lab model prioritizes parameter adjustability (±0.1MPa pressure, 0.1mm thickness control) and small-footprint design—critical for R&D rather than mass production .
