Custom Comb Shapes and Sizes
Put the overall profile, every tooth zone and any handle or moving part on one controlled drawing.
- Critical dimensions separated from reference dimensions
- Feasibility checked against the selected material and route
Start With the Use and a Controlled Drawing
A reference sample can show intent, but the drawing should define what production and inspection will measure. Mark requirements as fixed, preferred or open so feasibility changes remain visible.
- Start with: Intended use, material direction and an existing comb, sketch, CAD file or annotated image
- Dimension together: Overall envelope, thickness, tooth zones, tip profile, handle and branding area
- Flag for review: Small radii, thin sections, long teeth, hinges, mirrors and other assembled parts

Build the Drawing in Four Layers
Each layer answers a different production question and should stay on the same drawing revision.
1. Set the Overall Envelope
Define length, width, thickness, corners and the datums used to locate other features.
- Identify critical dimensions and reference-only dimensions
- Show front, side and section views where thickness changes
- Record the units and drawing revision
2. Specify Every Tooth Zone
Define tooth count or pitch, gap, length, taper, root and tip profile for each zone.
- Do not describe a zone only as fine, medium or wide
- Show transitions between mixed or dual-sided layouts
- Review fine, thin or long teeth against material stiffness
3. Add Handles, Tails or Moving Parts
Show the grip, tail, pivot, stop, mirror or case interface as part of the product rather than a later accessory.
- Check grip, balance, open and closed positions where relevant
- Define clearances and assembly relationships
- Use a functional sample for hinges and other moving parts
4. Confirm the Production Route
Review whether the approved geometry suits an existing route, a modified design or new tooling.
- Injection molding for suitable plastic structures
- Sheet, wood or bamboo cutting for relevant materials
- Confirm tooling, finishing, achievable tolerance and sample route in the quotation
What Must Be Approved Before Production
The drawing controls measurable requirements; the physical sample confirms form, finish and function.
Define Inputs
Send intended use, reference, material direction, target dimensions, tooth layout, quantity and functions.
Review the Drawing
Resolve open dimensions, datums, tooth zones, branding areas and any assembly details before sampling.
Approve the Sample
Record the approved drawing revision and sample as the production and inspection references.
Have a Drawing, Sample or Annotated Image?
Send it with the intended use, material direction, quantity and the dimensions that cannot change.
