Hydraulic Drive

Proportional pressure valve with pressure holding and slow-release ejection for stable pan density.

Product Introduction

The Hydraulic Cosmetic Powder Pressing Machine uses a hydraulic power unit to generate pressing force for compacting loose cosmetic powders into pressed pans and compacts. Pressure is regulated through a proportional valve, allowing the pressing profile to be adjusted for different powder formulations, particle sizes, and binding systems. The machine performs quantitative filling, pre-pressing, main pressing, and ejection in sequence, with dwell time and pressing speed set through the PLC touchscreen. Tooling is interchangeable for round, square, oval, and custom-shaped pans. The hydraulic circuit includes pressure holding and slow-release functions to reduce edge cracking and surface lamination. This equipment is applied in eyeshadow, blush, foundation, highlighter, and bronzer production where consistent pan density and repeatable batch output are required.

Core Advantages

Proportional Pressure Regulation

Hydraulic pressure is adjusted through a proportional valve, allowing pressing force to be tuned in fine increments for different formulas.

Pressure Holding Function

The hydraulic circuit maintains pressure during the dwell phase, supporting uniform density across the pan surface.

Slow-Release Ejection

Controlled pressure release during ejection reduces the risk of edge cracking and pan deformation.

Adjustable Dwell Time

Dwell time can be extended for formulas that require longer compaction to reach stable density.

Interchangeable Tooling

Punch and die sets can be replaced to accommodate different pan shapes, sizes, and embossing patterns.

Enclosed Powder Handling

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

Frequently Asked Questions and Solutions

Pan edges show cracking after pressing

Reduce main pressing speed, extend dwell time, or adjust the slow-release setting on the hydraulic circuit.

Inconsistent pan density

Verify hydraulic pressure stability, check the proportional valve setting, and confirm dwell time matches the formula requirement.

Powder sticking to punch faces

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

Hydraulic pressure drop during pressing

Inspect the hydraulic power unit for oil level, check the pressure relief valve setting, and look for internal leakage in the cylinder seals.

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.

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

Replace hydraulic oil and filter according to the maintenance schedule to maintain pressure response.

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

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

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