Profiles and finished panels
Machine outside profiles, internal windows, cable paths and mounting patterns from the released drawing. Custom panels are quoted as finished components, not as retail sheet supply.
Custom Acrylic Fabrication Service
Acrylic CNC Service for Production Parts
Custom PMMA parts, bases and finished panels made to your released drawing.
Our acrylic CNC service takes buyer-controlled geometry from drawing review through paid sample and repeat production. Wetop machines clear, colored and frosted cast PMMA for OEM teams, product companies, laboratories and retail-fixture programs, with a production MOQ of 100 pieces per design and a standard 15-20 day production window after approval.

Paid samples take 3-5 days. Sample fees are paid separately and never credited. Production timing starts after the drawing, sample and payment gate are approved.
What we machine
Acrylic CNC Machining for Functional Geometry
CNC machining is the right acrylic process when the drawing contains pockets, stepped faces, countersinks, controlled holes or thick-stock geometry that cannot be produced by a flat cutting path alone. Wetop quotes the process against the released drawing and validates it on a paid sample before production.
Pockets and stepped geometry
Use CNC when a part needs recessed pockets, shoulders, counterbores or stepped faces that a 2D laser path cannot produce.
Holes and mating features
Define hole type, datum, mating hardware and inspection method on the drawing. We confirm the machining route before the paid sample.
Bases, fixtures and components
Build repeatable acrylic bases, holders, jigs, lab fixtures and OEM components in production quantities from 100 pieces per design.
Edge and surface finishing
Call out which edges are visible, functional or hidden. Machined edges can be left matte or finished by the approved polishing route.
Assembly and packing
Add bonded parts, inserts, labels and protective packing only after the sample proves fit, appearance and the final packout sequence.
Process decision
CNC Machining vs Laser Cutting
Use CNC for three-dimensional or fit-critical features; use laser cutting for efficient two-dimensional sheet profiles when the required edge and thickness are compatible. A mixed process is common, but the quote should state which route controls each feature.
| Drawing feature | CNC machining | Laser cutting |
|---|---|---|
| Pockets, steps and recesses | Primary route | Not a 3D pocketing process |
| Flat outside profiles | Useful when edge geometry or stock requires it | Efficient for compatible sheet profiles |
| Countersinks and controlled bores | Defined from drawing and toolpath | Requires a secondary operation |
| Visible edge requirement | Machined texture or follow-up finish | Process edge depends on material and settings |
| Fit-critical inspection | Datum and gauge agreed before sample | Profile and heat-effect review before sample |
Need the engineering tradeoff in more detail? Read the CNC versus laser cutting guide and the acrylic fabrication tolerance guide.
Specification control
What the Production Drawing Must Control
A useful CNC drawing separates functional dimensions from reference dimensions. It states the datum structure, limits, material, visible surfaces, edge condition, revision and inspection method so the sample can be approved against the same record used in production.
| Drawing field | What to state | Why it changes the quote |
|---|---|---|
| Material | Named PMMA grade, color and starting stock | Stock condition affects sourcing and toolpath review |
| Datums | Faces or features that control measurement | Workholding and inspection need the same reference |
| Critical limits | Only the dimensions that control fit or movement | Tighter limits can add setup, inspection and scrap risk |
| Machined features | Pockets, holes, threads, countersinks and edge breaks | Each feature changes tools, passes and cycle time |
| Appearance zones | Visible faces, polish route and acceptable sample | Functional and cosmetic surfaces need different handling |
| Revision | One released drawing and artwork revision ID | Prevents an old file from controlling production |
Evidence and planning
Two CNC-Heavy Programs to Review
These pages show how a drawing-controlled acrylic component or fixture can be planned. They do not replace your own drawing, material specification or sample acceptance record.
Manufacturing Case
Precision Acrylic Component Production Plan
Drawing release, first-article review, inspection planning and controlled packout for a fit-critical component.
Manufacturing Case
Custom Laboratory Rack Planning Model
Hole geometry, material limits, physical sample review and production control for a multi-position rack.

Send These 8 Inputs for a CNC Quote
A complete brief lets engineering identify the process, sample scope and inspection plan without guessing. If the design is early, send the known inputs and label the open decisions.
- Released STEP, DXF or dimensioned PDF, with one controlling revision ID
- Quantity per design and the quantity tiers you want quoted
- Named acrylic grade, color, thickness or starting stock
- Fit-critical dimensions, limits, datums and mating-part information
- Hole, pocket, thread, countersink and edge-finish requirements
- Inspection records, cosmetic zones and sample acceptance method
- Packing, labeling, destination and requested Incoterm
- NDA or IP handling requirements before file release
Supplier choice
Factory, Local Job Shop or Catalog Supplier?
| Buying route | Best fit | MOQ and timing | Important boundary |
|---|---|---|---|
| Wetop factory program | Repeat acrylic parts with a released drawing and production quantity | MOQ 100/design; sample 3-5 days; production 15-20 days | Not a one-off rapid-prototyping shop |
| Local CNC job shop | One-off development, same-day iteration or onsite fit work | Often accepts very small quantity; local rate applies | Confirm acrylic-specific finishing and cosmetic handling |
| Catalog / sheet supplier | Standard stock, blank sheet or simple cut size | Stock-dependent | Does not replace drawing-controlled production and inspection |
Payment: standard production terms are 30% deposit and 70% balance before shipment. Shipping: request both FOB Shenzhen and DDP if you need a factory-price and landed-cost comparison. Inspection: agree the acceptance window and evidence required before the order starts.

Buyer questions
Acrylic CNC Service FAQ
What is the MOQ for acrylic CNC machining service?
Production starts at 100 pieces per design. A different geometry, material, thickness or controlling drawing revision may count as a separate design. A paid pre-production sample is ordered separately before the production run.
How much does acrylic CNC machining cost?
The quote is driven by starting stock, machine time, tool changes, workholding, quantity, inspection scope, finish and packing. Send the drawing and the quantity tiers you are considering; we return an itemized production quote within 24 hours. We do not apply a generic per-part price to unmatched geometry.
What tolerance can Wetop hold on a CNC acrylic part?
Tolerance is reviewed dimension by dimension against the drawing, material, stock condition, geometry, datum plan and measurement method. Mark fit-critical dimensions and their acceptable limits. We confirm the quoted capability and inspection method before sampling instead of promising one tolerance for the entire part.
Which file formats should I send?
Send STEP for 3D geometry, DXF for controlled 2D profiles and a dimensioned PDF that identifies critical dimensions, material, finish and revision. The CAD and DXF preparation guide explains how the files work together.
Should my acrylic part be CNC-machined or laser-cut?
CNC is normally the better route for pockets, steps, countersinks, controlled holes, thick stock and functional edge geometry. Laser cutting is efficient for repeated 2D profiles in suitable sheet thicknesses. The CNC versus laser guide separates the two by geometry and finish.
Can I approve a prototype before production?
Yes. Paid samples normally take 3-5 days after the drawing, material and acceptance criteria are approved. Sample fees are paid separately and never credited. Production starts only after written sample approval and the agreed payment gate.
Can Wetop sign an NDA before I share drawings?
Yes. Send the NDA requirement first and identify who controls the drawing release. We keep the approved revision, inspection plan and artwork references tied to the project record; no customer names or files are published without permission.
Can you ship CNC acrylic parts DDP?
Yes. Ask for FOB Shenzhen and DDP as separate quote lines if you need to compare factory price with door-to-door landed scope. The final DDP line depends on the packed dimensions, weight, destination and current freight and duty treatment.
