Pneumatic Cosmetic Powder Pressing Machine

Air-driven pressing system for cosmetic powder compaction, using a pneumatic cylinder and proportional air pressure regulator to control pressing force, dwell time, and release speed across different powder formulations.

1-10 Tons Pressing Force

25-60 Pans Per Minute

0.6-0.8 MPa Air Supply

Product Introduction

The Pneumatic Cosmetic Powder Pressing Machine uses compressed air as the driving source to compact loose cosmetic powders into pressed pans and compacts. A pneumatic cylinder, paired with a proportional air pressure regulator, controls the pressing force applied to each pan. The system performs quantitative filling, pre-pressing, main pressing, and ejection in one cycle, with pressure, dwell time, and release speed set through the PLC touchscreen. Because the drive medium is air rather than hydraulic oil, the machine avoids oil leakage risk in the powder handling area and simplifies routine maintenance. Tooling is interchangeable for round, square, oval, and custom-shaped pans. The machine is applied in eyeshadow, blush, foundation, highlighter, and bronzer production where moderate pressing force and clean operation are required.

Core Advantages

Air-Driven Pressing

Compressed air drives the pneumatic cylinder, removing hydraulic oil from the pressing area and reducing contamination risk near the powder zone.

Proportional Air Regulation

A proportional air pressure regulator adjusts pressing force in fine increments, allowing pressure profiles to be matched to different powder formulations.

Adjustable Release Speed

Exhaust flow control valves regulate punch retraction speed, reducing edge cracking and surface lamination during ejection.

Simplified Maintenance

The absence of hydraulic oil circuits reduces maintenance tasks, with servicing focused on air filter, regulator, and cylinder seal inspection.

Cleaner Working Area

Air exhaust is routed away from the powder zone, keeping the pressing area free from oil mist and limiting powder adhesion to tooling surfaces.

Interchangeable Tooling

Punch and die sets can be replaced for different pan shapes, sizes, and embossing patterns on the same machine frame.

Frequently Asked Questions and Solutions

Pressing force fluctuates between cycles

Check the air supply pressure stability, inspect the proportional regulator for contamination, and verify the air filter element condition.

Pan edges show cracking after pressing

Reduce main pressing speed, extend dwell time, or adjust the exhaust flow control valve to slow punch retraction.

Powder sticking to punch faces

Apply approved mold release agent, reduce pressing force, or lower powder moisture content before pressing.

Air cylinder movement is slow or irregular

Inspect cylinder seals for wear, check the air line for leakage or blockage, and confirm the lubricator is functioning if fitted.

Inconsistent pan weight

Check filling auger calibration, verify powder bulk density stability, and inspect the hopper for bridge formation.

Surface unevenness or lamination

Increase pre-press pressure, adjust powder particle size distribution, or extend dwell time during main pressing.

Changeover time between formats

Use quick-release tooling clamps and recall stored recipes from the PLC for each product code.

Operating Notes

Verify powder moisture content before pressing; excessive moisture causes sticking and delamination.

Drain the air line moisture trap at the start of each shift to prevent water entering the pneumatic circuit.

Check air filter and regulator elements according to the maintenance schedule to maintain pressure accuracy.

Clean the pressing area after each batch to prevent cross-contamination between color formulas.

Calibrate the filling system when changing to a powder with different bulk density.

Do not exceed the maximum pressing force specified for the installed tooling set.

Inspect cylinder rod and seal condition during routine maintenance for air leakage.

Keep the PLC ventilation filter clean to avoid overheating in continuous operation.

Store tooling in a dry environment to prevent corrosion on contact surfaces.
