Rotary Series

Rotary Cosmetic Powder Pressing Machine

Rotary indexing pressing system for continuous cosmetic powder compaction, with synchronized filling and pressing stations, servo-driven pressure control, and enclosed powder handling.

Product Introduction

The Rotary Cosmetic Powder Pressing Machine is built on a rotary indexing platform that carries pans through filling, pre-pressing, main pressing, and ejection positions in a continuous cycle. The synchronized station layout allows each pan to receive identical processing time at every stage, supporting stable pan density and repeatable surface quality. Pressure is applied through a servo-driven hydraulic system, with parameters set on the touchscreen interface and stored as product recipes. Tooling is interchangeable for round, square, oval, and custom pan profiles. The enclosed powder feeding zone, combined with a recovery channel, limits material loss during filling and pressing. The machine is suited to eyeshadow, blush, foundation, highlighter, and bronzer production lines requiring steady output and consistent pan weight.

Core Advantages

Continuous Rotary Cycle

The rotary indexing platform moves pans through each processing stage without stopping, maintaining steady production flow.

Servo-Driven Pressure

Pressing force is regulated by a servo-hydraulic system, allowing pressure profiles to be set and repeated across cycles.

Synchronized Station Timing

Each station operates on the same index cycle, so every pan receives equal filling, pre-press, and main press time.

Recipe-Driven Setup

Product parameters are stored in the PLC, reducing setup time when switching between formulas and pan formats.

Enclosed Powder Zone

Feeding and recovery are contained within the machine frame, limiting airborne powder and material buildup.

Tooling Interchangeability

Punch and die sets can be replaced to accommodate different pan shapes and sizes on the same rotary table.

Sample and Travel Palettes

Small pan pressing for sample kits and travel-size palettes using stored recipe parameters.

Frequently Asked Questions and Solutions

Uneven density between stations

Check individual station pressure calibration and inspect the rotary manifold for hydraulic pressure drop.

Pan edges show cracking after pressing

Reduce main pressing speed, extend pre-press dwell time, or adjust binder ratio in the powder formula.

Inconsistent pan weight across stations

Verify filling auger calibration per station, confirm powder bulk density stability, and inspect the hopper for bridge formation.

Powder sticking to punch faces

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

Rotary table indexing error

Inspect the index drive mechanism, verify encoder signal, and check station guide rails for obstruction.

Changeover time between formats

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

Surface unevenness or lamination

Increase pre-press pressure, adjust powder particle size distribution, or reduce main pressing speed.

Operating Notes

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

Clean each station after each batch to prevent cross-contamination between color formulas.

Check hydraulic oil level and pressure stability at the start of each shift.

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

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

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

Inspect punch and die surfaces for wear or scratches during routine maintenance.

Verify rotary table indexing accuracy after any tooling change or station adjustment.

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