Automatic Blush Pressing Machine
A pressing platform configured for blush and face powder pan production, covering domed, flat, and embossed formats. The machine automates pan feeding, powder dosing, compaction, and ejection within a single cycle, with recipe driven control of fill weight, pressing force, and dwell time. Applied to single shade runs, multi shade range production, and palette bound blush pan formats.
Pan Feed
Blush pans are presented from a magazine or tray loader into the indexing plate. Pan presence and orientation are confirmed by sensor before the cycle advances.
Powder Dose
A servo auger fills each pan to the recipe weight. An inline check weigher verifies the dose, and out of tolerance pans are diverted before pressing.
Bed Leveling
A scraper or light vibration step levels the powder bed so density is uniform before the punch contacts the powder surface.
Compaction
The upper punch descends at a controlled rate to the set force and holds for the recipe dwell value. Force and position are recorded per pan.
Ejection
The pressed pan is lifted from the die and transferred to a discharge conveyor or tray loading unit. Ejection stroke is set to match pan depth.
Inspection
Pan height, surface condition, and weight are checked at an inspection point. Results are linked to the batch record for traceability.
Capabilities for Blush Production
Functions configured for blush and face powder pan formats.
Domed Pan Support
Domed and rounded blush pans pressed with a curved upper punch. Contact velocity and compaction gradient are set per recipe to protect the dome profile.
Large Diameter Pans
Pan formats from 25 mm to 75 mm diameter are supported through interchangeable die plates. Larger face powder pans are available on request.
Shade Specific Recipes
Each blush shade and formulation stores its own fill weight, force, dwell time, and ejection setting. Recipe recall is done from the HMI.
Embossed Surface Pressing
Upper punches with logo or pattern relief are supported. Approach speed and compaction gradient are reduced to preserve detail on the pan face.
Soft Formulation Handling
Lower density blush formulations pressed at reduced force with extended hold time to limit over compaction and surface cracking.
Batch Level Reporting
Fill weight, pressing force, pan count, and reject counts logged per batch. Data exportable through OPC UA or CSV for quality review.
Technical Data
Standard configuration values. Pan size, force range, and tooling defined per project.
Production Fit
Where the blush pressing machine is deployed in cosmetic manufacturing.
Single Shade Volume Runs
Long runs of a single blush shade on standard pan sizes, with output stability maintained across shifts and consistent pan hardness.
Domed Blush Formats
Domed and rounded pans produced with curved tooling, where pressing parameters protect the dome profile and limit cracking at the edge.
Seasonal Shade Range
Smaller batch campaigns where recipe recall and short changeover times support frequent transitions between shades and pan formats.
Embossed Blush Pans
Pans with surface relief or textured finish where pressing parameters are tuned to preserve the punch detail through compaction.
Palette Bound Blush
Multi pan palettes where blush pans are produced and assembled in a coordinated sequence for a single palette format.
Sample and Promotional Units
Reduced force settings and shorter cycles for sample pans and promotional formats without changing the machine setup.
Frequently Asked Questions
Common questions raised during evaluation and line integration. Select a question to expand the answer.
Which blush pan formats can the machine handle
Round, oval, rectangular, and domed pan formats are supported through interchangeable die plates. Standard range covers 25 mm to 75 mm diameter or equivalent footprint, with larger formats available on request.
How is fill weight controlled for each pan
Powder is dosed by a servo driven auger using a volumetric fill method. An inline check weigher confirms weight against the recipe value, and out of tolerance pans are diverted before pressing. Fill weight is normally held within plus or minus 0.04 g.
Can domed blush pans be pressed without cracking
Yes. Domed tooling uses a reduced compaction gradient and a lower contact velocity so the powder bed deforms progressively. Hold time is extended per recipe, which allows the binder to settle and limits cracking around the dome edge.
What tooling changeover time should be expected
A full tooling set change typically takes 20 to 45 minutes, depending on pan shape and the number of positions to be updated. Tooling is stored by recipe code and staged before changeover to minimize downtime.
Can the machine run soft or low density blush formulations
Yes. Soft and low density blush formulations are pressed at reduced force with extended hold time. Compaction gradient is set per formulation to prevent over compaction, which would otherwise reduce powder spreadability and cause surface cracking.
What data is logged per batch
Fill weight, pressing force, dwell time, pan count, and reject counts are logged per batch. Cycle level data can be exported through OPC UA or CSV for quality documentation and process review.
What maintenance intervals apply to the press
Punch and die inspection is recommended every 500 hours, auger and dosing system cleaning at every shade change, indexer calibration every 1,000 hours, and load cell verification every 12 months. Records are kept alongside the machine maintenance log.
Can the machine integrate with existing palette assembly lines
Yes. The discharge station provides a position identified signal that downstream palette assembly or tray loading equipment can use for alignment and sequencing. Integration requirements are defined during line layout planning.
Process Deviation Reference
Situations observed during blush pressing and the corresponding corrective actions.
Dome surface cracks after pressing
Extend dwell time by 0.5 to 1 second and reduce the compaction gradient. Verify the dome punch geometry against the tooling record. Confirm powder moisture content remains between 1 and 3 percent.
Fill weight varies across positions
Run the per position calibration routine for the affected auger. Confirm powder bulk density consistency in the hopper and check the auger screw for wear. Verify hopper level remains above 30 percent during production.
Powder sticks to the upper punch
Reduce the pressing force by 10 to 15 percent and shorten the hold time. Polish the punch surface and confirm the release angle matches the tooling specification. Verify powder temperature and moisture content before production.
Pan not fully ejected from die
Verify the ejection stroke matches the pan depth setting. Inspect the ejector rod for contamination and clean the die wall. Confirm the lower punch returns fully before the next fill stage.
Embossed pattern blurs on the pan surface
Reduce the approach speed in the affected stage and lower the contact velocity. Check the punch face for powder build up and inspect for tool wear. Increase hold time slightly to allow the pattern to register before release.
Check weigher rejects exceed normal range
Verify the check weigher calibration against a reference balance. Inspect the auger and dosing barrel for powder build up. Confirm the powder supply has not shifted in particle size or moisture content between batches.
Integration Notes
Factors that affect installation, utilities, and long term operation.
Powder Supply
A buffer hopper with level feedback is recommended upstream. Powder should be dry, free of lumps, and within the specified particle size range before loading.
Downstream Transfer
The discharge station is compatible with conveyor transfer, tray loading, or robotic pick and place. A position identified signal supports downstream sorting and palette assembly alignment.
Tooling Storage
Punch and die sets should be stored in labeled racks with protective coating. Tooling records with clearance values accompany each pan format and recipe code.
Maintenance Planning
Recommended intervals cover punch and die inspection every 500 hours, indexer calibration every 1,000 hours, auger cleaning at each shade change, and load cell verification every 12 months.
