The work
behind the brush.

A brush takes shape through a sequence of making and checking stages. Explore the process behind custom development.

A closer look

Small components.
Many considered steps.

These photographs offer a view of the workbench and the making process. PRETTY brings the development brief, production details and sample review into one conversation.

Each brush begins with decisions about its bristles, ferrule and handle. The steps below show how components take shape through making, assembly and inspection.

Inside the making

Adhesive application

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.

Head shaping

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.

Ferrule crimping

The ferrule is worked with a crimping tool. The connection and construction details belong in the development specification.

A finished silhouette depends on the relationship between the head, ferrule and handle. Confirm the component details together.

Making & checking

28 steps.
One considered process.

Follow our bristle-brush production workflow, from incoming material to dispatch. Open each stage to see how the brush takes shape and where inspection enters the process.

01 · Steps 1—4

Material preparation

Which material and preparation requirements belong in the specification?

  1. Incoming bristle inspectionInspection point

    Check the incoming bristles against the material and sample requirements.

  2. Bristle preparation

    Prepare the bristles for the selected brush head.

  3. Bristle weighing

    Weigh the bristles for the intended bundle.

  4. Removal of unwanted fibres

    Remove unwanted fibres before forming the head.

02 · Steps 5—8

Head shaping

Does the profile match the intended application?

  1. Place the bristles in a shaping cup

    Place the prepared bundle into a shaping cup.

  2. Tap the cup to shape the bristle bundle

    Tap the cup to settle the bristles and form the profile.

  3. Tying the bristle bundle

    Tie the formed bundle for the next handling stage.

  4. Bristle-profile inspectionInspection point

    Check the formed bristle profile.

03 · Steps 9—15

Ferrule fitting and bonding

Are the dimensions and component fit agreed?

  1. Ferrule fitting

    Fit the prepared head into the ferrule.

  2. Dimensional checkInspection point

    Check the dimensions at this stage of assembly.

  3. Removing the temporary tie

    Remove the temporary thread used to hold the bundle.

  4. Ferrule pressing

    Press the ferrule to the required profile for the construction.

  5. In-process inspectionInspection point

    Inspect the assembly before the adhesive stage.

  6. Adhesive application

    Apply adhesive to secure the bristle assembly.

    View the on-site photograph →
  7. Drying after adhesive application

    Dry the bonded assembly under the conditions selected for the adhesive.

04 · Steps 16—20

Head finishing and protection

What should the finished head look and feel like?

  1. Head-profile finishing

    Finish the head to the intended silhouette.

    View the on-site photograph →
  2. Removal of unwanted hairs

    Remove unwanted hairs from the formed head.

  3. Loose-fibre removal

    Remove loose fibres as part of head finishing.

  4. Finishing inspectionInspection point

    Inspect the head after finishing.

  5. Protective sleeving

    Apply a protective sleeve before subsequent handling.

05 · Steps 21—24

Handle assembly

How should alignment and connections be reviewed?

  1. Handle assembly

    Assemble the handle and prepared head components.

  2. Alignment adjustment after assembly

    Adjust alignment after assembly and before drying.

  3. Drying

    Dry the handle assembly under the agreed bonding conditions.

  4. Handle pull check after drying

    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.

06 · Steps 25—28

Final review, packing and dispatch

What is inspected, how is the lot sampled, and how is the order packed?

  1. Full inspectionInspection point

    The board identifies a full-inspection stage. Agree which visual and assembly checks are included for each item.

  2. Sampling inspectionInspection point

    The board identifies a sampling stage. Agree the lot, selection method, checks and acceptance rules.

  3. Packing

    Pack the products and check the agreed set contents, protection and labelling.

  4. Dispatch

    Release the packed goods for dispatch against the order and packing documents.

Use this workflow to discuss your production and inspection requirements. Connection-check methods, test forces and acceptance criteria are agreed with your product specification.

Your product. Your acceptance criteria.

Agree what
a good sample means.

Use these common review topics to build the checks for your order. The method, coverage and acceptance criteria are recorded with your agreed specification.

Full inspection

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.

Discuss your quality requirements

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

Reviews during making

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 making sequence includes full and sampling inspection before packing. Define the checks for every item, the checks made on a sample and the acceptance rules for your order.
