Explore the stages of brush production, from preparing the bristles to assembling and inspecting the finished product. Use the process guide to plan the specifications and quality checks for your order.
Handle preparation · on-site photograph
From the first fibre
Formed with care. Reviewed in detail.
Follow 28 illustrated operations, from bristle preparation and shaping to assembly, inspection and dispatch. Follow how the brush head, ferrule and handle are prepared and assembled.
Before approving a sample, agree the head shape, dimensions, materials and the criteria you will use to assess it.
Adhesive is applied inside the brush-head assembly. Drying follows as a separate stage in the recorded process.
The selected materials and construction determine the assembly details to confirm for your project.
How can PRETTY help me specify the brush assembly?
Bring your preferred head, ferrule and handle materials, together with the formula and care routine the brush will be used with. We can review the proposed construction for your design and put the connection checks into the sample brief.
The brush surface is shaped at the workbench. This is where the outline of the head becomes visible in the making process.
Use the sample review to discuss the head profile, proportions and the feel you want to achieve.
How can I develop a brush head with PRETTY?
Start with a brush-head reference and the application you want to achieve. Compare the outline, working width and bristle length, then send the reference with your formula and feel preferences. This gives our sample review a specific shape and use to work towards.
The ferrule is worked with a crimping tool. The connection and construction details belong in the development specification.
Check how the head, ferrule and handle fit together, and record the connection requirements in the product specification.
What should my brief include for a custom brush ferrule?
Show us the ferrule profile and finish you want, along with the head and handle it will join. We can review their fit as one assembly. Include alignment, gaps, grip comfort and any strength-check requirements in the sample brief so the review covers your intended construction.
Explore the illustrated workflow from incoming bristles to dispatch. Each numbered operation includes the factory-board reference and the points to discuss for your own product.
Use these common review topics to build the checks for your order. The method, coverage and acceptance criteria are recorded with your agreed specification.
Review topic
What to look at
Agree for your project
Material & incoming components
Identity documents, visible contamination, colour and component condition.
Define the visual and assembly checks applied to every item at step 25. A full visual check does not mean that every item undergoes every functional or destructive test.
Sampling inspection
Define the lot, random selection, defect categories and acceptance rules. ISO 2859-1:2026 is one framework to discuss where appropriate; no AQL is assumed for your order.
Packing & release
The board places sampling before packing. Check packaging and set completeness during steps 27–28, or agree a separate review of packed goods.
The checklist uses public manufacturing references and NIST’s explanation of acceptance sampling. These are proposed review topics, not a record of tests already passed by PRETTY products.
Plan the quality checks for your order Appearance, construction and sample review
Making. Checking. Confirming.
Quality checks, from bristle to brush.
Review materials, head shape and dimensions during development, with in-process and final checks included in the making sequence. Agree the methods and acceptance criteria for your order before production.
01
Steps 1, 8 and 10
Material, shape and dimensions
Begin with incoming bristles, head shape and dimensions. Keep the approved material, profile and measurement points with your product specification.
02
Steps 13 and 19
Checks during assembly
Check the assembly after ferrule forming and review the head again after finishing. Agree how your sample will be checked for shape, loose fibres, connections and appearance.
03
Steps 25 and 26
Full and sampling inspection
The production sequence includes full inspection and sample-based inspection before packing. Define the checks for every item, the checks made on a sample and the acceptance rules for your order.

What are the main stages of makeup brush production?+
The recorded workflow groups 28 operations into bristle preparation, head shaping, ferrule fitting and bonding, head finishing, handle assembly, and final inspection with packing and dispatch. Follow the illustrated process for individual operations. Order-specific materials and inspection criteria still belong in the agreed specification.
Where does brush-head shaping fit into the production process?+
The board places initial head shaping at steps 5–8, followed by ferrule fitting and later finishing at step 16. Review the intended outline, dimensions and the finished head on the sample. A shaping illustration explains the sequence but does not certify that a particular batch matches the profile.
When are makeup brush dimensions checked?+
Step 10 is the recorded dimension-check stage; step 8 reviews head shape, and later inspection stages follow assembly and finishing. Agree which dimensions will be recorded for your product and at which checks. A stage label alone does not state measurement points, tolerances or lot results.
What is the difference between full inspection and sampling inspection?+
Full inspection means checking every item for the characteristics specified for that inspection. Sampling inspection examines selected units using an agreed lot and acceptance plan. Neither term means every possible test is performed; identify the visual, dimensional and functional checks and record their respective coverage.
How should loose fibres be assessed on a brush sample?+
Agree how the sample is handled or used during the check, for how long, and how loose fibres will be counted or recorded. Compare before and after the agreed care routine if relevant. Distinguish isolated loose fibres from continuing loss, then judge against written criteria for that construction.
How do I agree a joint-strength test with a brush supplier?+
Specify the connection being assessed, loading direction, fixture, force or method, duration, sample count and acceptance rule. Agree whether the test is destructive and how results will be recorded. Do not copy a generic force value onto every brush without reviewing the materials and construction.
What should I inspect around the ferrule and handle connection?+
Look for alignment, gaps, movement, sharp edges, excess adhesive and finish damage at the joint. Review the assembly in the intended grip and after any agreed functional checks. Keep visible inspection separate from a specified strength test, because an even-looking joint does not prove its strength.
How should a brush be evaluated after an agreed cleaning routine?+
Record the cleaning method, product, water conditions, duration and drying arrangement agreed for the construction. Compare head shape, loose fibres, finish and connection condition afterwards. Report the actual observations and procedure; a passed review under one procedure is not a claim of unlimited wash durability.
What quality evidence should be recorded before packing?+
Record the product and lot reference, inspection date, sample or full-check coverage, methods, results and disposition of nonconforming items. Before release, also check the approved set contents, labels and packaging. The workflow places sampling at step 26 and packing at step 27; agree any final packed-goods review separately.
Does a production-process illustration prove that a product passed a test?+
No. An illustration explains an operation, while a test result needs an identified sample or lot, method, date and observed result. This site's process visuals include labelled illustrations and on-site photographs. Ask for order-specific records when you need evidence that an agreed check has been passed.
