The making of a makeup brush
A brush takes shape through material preparation, head shaping, component assembly and inspection. Follow the numbered workflow, then bring the details that matter to your sample review.
AI process illustrations explain the recorded workflow. They are not photographs of our workshop. See the on-site photographs
Chapter 01 · Steps 1—4
Which material and preparation requirements belong in the specification?
Check the incoming bristles against the material and sample requirements.
Sample discussion: Identify the fibre and approved reference, not only its colour.
1. 原毛检查
Prepare the bristles for the selected brush head.
Sample discussion: Record the blend and preparation for this design.
2. 准备毛
Weigh the bristles for the intended bundle.
Sample discussion: Compare fullness as well as the specified bundle weight.
3. 秤毛量
Remove unwanted fibres before forming the head.
Sample discussion: Look for unwanted fibres against the agreed appearance sample.
4. 除杂毛
Chapter 02 · Steps 5—8
Does the profile match the intended application?
Place the prepared bundle into a shaping cup.
Sample discussion: Match the cup profile to the requested head outline.
5. 放入蹲杯
Tap the cup to settle the bristles and form the profile.
Sample discussion: Compare the settled tip shape with the approved sample.
6. 墩罐
Tie the formed bundle for the next handling stage.
Sample discussion: Check that handling preserves the formed profile.
7. 捆线
Check the formed bristle profile.
Sample discussion: Review the front and side silhouette.
8. 验毛形
Chapter 03 · Steps 9—15
Are the dimensions and component fit agreed?
Fit the prepared head into the ferrule.
Sample discussion: Compare ferrule opening and exposed bristle length.
9. 套管
Check the dimensions at this stage of assembly.
Sample discussion: Use named measurement points and agreed tolerances.
10. 量尺
Remove the temporary thread used to hold the bundle.
Sample discussion: Review the bundle after the temporary tie is removed.
11. 拆线
Press the ferrule to the required profile for the construction.
Sample discussion: Check the intended round or flattened ferrule profile.
12. 压扁
Inspect the assembly before the adhesive stage.
Sample discussion: Check fit and alignment before the bonded joint becomes fixed.
13. 检验
Apply adhesive to secure the bristle assembly.
Sample discussion: Agree the adhesive specification and compatible component materials.
Dry the bonded assembly under the conditions selected for the adhesive.
Sample discussion: Use the selected adhesive data sheet, not a universal drying time.
15. 烘干
Chapter 04 · Steps 16—20
What should the finished head look and feel like?
Finish the head to the intended silhouette.
Sample discussion: Distinguish shaping the profile from indiscriminate tip cutting.
Remove unwanted hairs from the formed head.
Sample discussion: Review stray hairs without changing the agreed silhouette.
17. 拔毛
Remove loose fibres as part of head finishing.
Sample discussion: Agree a repeatable shedding check and acceptance criteria.
18. 扑毛
Inspect the head after finishing.
Sample discussion: Compare outline, dimensions and visible finish with the sample.
19. 检验
Apply a protective sleeve before subsequent handling.
Sample discussion: Check protection without crushing or bending the working head.
20. 套袋
Chapter 05 · Steps 21—24
How should alignment and connections be reviewed?
Assemble the handle and prepared head components.
Sample discussion: Compare handle, ferrule and logo orientation together.
21. 组装
Adjust alignment after assembly and before drying.
Sample discussion: Review straightness from more than one viewing angle.
22. 正洁
The English explanation is interpreted from the board and sequence. Confirm the precise operation for your product.
Dry the handle assembly under the agreed bonding conditions.
Sample discussion: Confirm handling strength and full cure requirements separately.
23. 干燥
The board shows pulling the handle after drying. The connection-check purpose is interpreted from its place in the sequence; force, duration and acceptance criteria remain project-specific.
Sample discussion: Specify the test method, force, duration and acceptance rule.
24. 拔把子
The English explanation is interpreted from the board and sequence. Confirm the precise operation for your product.
Chapter 06 · Steps 25—28
What is inspected, how is the lot sampled, and how is the order packed?
The board identifies a full-inspection stage. Agree which visual and assembly checks are included for each item.
Sample discussion: List exactly which features are checked on every item.
25. 全检
The board identifies a sampling stage. Agree the lot, selection method, checks and acceptance rules.
Sample discussion: Agree lot size, sample selection, defect classes and decision rules.
26. 抽检
Pack the products and check the agreed set contents, protection and labelling.
Sample discussion: Check counts per set, head protection and approved artwork.
27. 包装
Release the packed goods for dispatch against the order and packing documents.
Sample discussion: Match released quantity and carton details to the order.
28. 出库
Understand the process
The 28 numbered operations follow the supplied factory flow board. The explanations below add published industry context. The sample-discussion prompts are a purchasing checklist, not a claim that a test or certification has already been completed.
A shaping cup or mould helps arrange the bundle into a profile. In the traditional process documented by Chikuhodo, fibres settle in a shaped frame, the base is secured and the head is refined before metal fitting and handle assembly. This explains the principle behind several steps above; it does not mean every material or brush construction follows an identical method.
See our head-shaping sequence →The adhesive and the assembly conditions matter. Henkel describes how temperature and the mass of a two-part epoxy can affect curing. Its epoxy guidance is an example, not a specification for the adhesive in your brush. For your project, request the selected adhesive technical data and distinguish safe handling from full cure before agreeing assembly and connection checks.
Follow bonding and drying →No. Acceptance sampling uses selected items to make a decision about a lot. ASQ distinguishes attribute-based and variable-based sampling plans. An every-item visual check and a lot-sampling plan answer different questions. Define the features, defect classes, lot, sample selection and acceptance rules for the order; a sampling pass does not certify that every piece has no defects.

From the workflow to your order
This sequence follows our supplied manufacturing board for bristle brushes. Non-bristle tools and different constructions can require other operations. Inspection coverage, test methods and acceptance criteria are agreed for each project.
