CNC & Laser Cutting

Profiles, cut-outs, holes and engraving from your DXF, DWG or STEP files — 22 machines.

Anything more complex than a rectangle runs on our CNC centres. Profiles, internal cut-outs, counterbored holes, engraved detail and 3D contour work all come off the same drawing file you already have.

CNC cutting tolerance can reach ±0.1 mm, subject to material, thickness, part geometry and drawing review.

CNC routing or laser cutting?

	CNC routing	Laser cutting
Polycarbonate	Yes — the correct method	No — leaves a yellowed, brittle edge
Cast acrylic	Excellent	Yes, frosted edge
Extruded acrylic	Fair	Excellent — polished edge
Thick material	Up to 30 mm+	Practical to about 20 mm
Fine detail	Limited by cutter diameter	Very fine

The important line is the first one: polycarbonate should not be laser cut. The heat leaves a discoloured, stressed edge that cracks in service. Any supplier offering laser-cut polycarbonate is telling you something about their process control.

Typical applications

Machine guard panels with cut-outs and fixings
Display components and retail fixtures
Engraved signage and control panel overlays
Prototype and short-run production parts
Gaskets, spacers and insulating components

Sheet Fabrication Processes

Jiangsu Xinjincheng provides diversified secondary processing to customer drawings and technical requirements.

01. Cutting

Sheets are set on the cutting machine to the required length and width.

02. Drilling

Hole diameter and position follow the customer drawing; routing equipment is used to reduce cracking risk in acrylic.

Bending and Thermoforming equipment and process

03. Bending and Thermoforming

Polycarbonate can be cold-bent at room temperature where the design permits, or hot-bent for formed parts.

CNC Routing and Engraving equipment and process

04. CNC Routing and Engraving

Parts are machined to drawings, including chamfers, bevels, rounded edges and countersinks.

Edge and Slot Milling equipment and process

05. Edge and Slot Milling

Dedicated cutters produce specified edges and internal grooves to the drawing geometry.

Screen and UV Printing equipment and process

06. Screen and UV Printing

Front or reverse printing, surface treatment and colour work can be applied to sheet components from customer artwork.

07. Polishing

Buff-wheel, flame or laser processes can be selected to improve edge clarity and finish.

08. Laser Processing

Laser engraving, cutting and marking are available where compatible with the selected sheet material.

Minimum order and lead time

Plastura’s Jiangsu fabrication team quotes CNC laser cut polycarbonate from the drawing. State the sheet material, thickness, finished dimensions, tolerance, edge finish, file format, and quantity. Standard stock sizes and colours normally run in 7–10 days; non-standard extrusion in 12–18 days; allow another 3–7 days for CNC work. The published starting point is 100 m² or 1 tonne, quoted in USD on FOB, CIF or DDP terms. See MOQ, lead time and shipping for planning details.

Questions buyers ask

Which file formats do you accept?

DXF, DWG, STEP, IGES and PDF, up to 90 MB per file through the quote form. Vector geometry is preferred; we can work from a dimensioned PDF but it takes longer.

Can you engrave text and logos?

Yes, engraved or laser-marked depending on material and depth. Send the artwork as vector geometry for the cleanest result.

Do you offer polished edges on cut parts?

Yes — diamond polished for optical clarity, or flame polished on cast acrylic. Specify per edge, since polishing every edge on a hidden part is wasted cost.

Buyer planning module

This page explains how a drawing is reviewed for CNC cutting feasibility and what must be confirmed before any tolerance is quoted.

For: It is for engineers and buyers who need cut or machined sheet parts from their own drawings.

Key variables: Variables are file format, material and grade, thickness, part size, critical dimensions, edge finish, and quantity.

Limit: CNC tolerance is an order-specific statement: achievable and quoted tolerances are confirmed per drawing and order.

Next step: Send the drawing with material, thickness, critical dimensions, finish, quantity, packing, and destination.

CNC workshop cutting polycarbonate parts to an approved drawing — CNC workshop reference from the Plastura site. Process, material, and tolerance remain order-specific until drawing review.

Send your drawing in the format your CAD system uses (for example DXF, DWG, STEP, IGES, or PDF) and ask which formats are currently accepted.

Use the existing tolerance paragraph above as the manufacturer-declared, order-specific reference; confirm the applicable value against the approved drawing, material, and quotation before release.

Distinguish capability review from acceptance: the supplier first reviews whether the drawing can be made, then states the tolerance for the specific geometry before any acceptance criteria are agreed.

Tolerance policy covers linear dimensions, hole positions, angles, thickness, and profile. Ask the supplier to state the critical dimensions and the tolerance required for each before quoting.

First-article approval: agree which critical dimensions are measured on the first article, who approves it, and which records are provided with the approval.

Kerf, tool radius, minimum hole or slot size, edge distances, stress and heat effects, protective film, and edge finish are process-specific. Ask which rules apply to your material, thickness, and geometry.

Ask how packaging of finished parts is handled and how parts are packed and protected before shipping, and state destination and target date in the RFQ.

Agree the drawing review flow: submission and revision, feasibility and tolerance review, first-article approval, then production release. Confirm the revision that will be produced.

Send the drawing, material, thickness, critical dimensions, tolerance, finish, quantity, packing, destination, and target date with the RFQ.

Do not assume laser processing is suitable for every PC or PMMA grade, thickness, protective film, or edge requirement. Ask which process, for example CNC routing or laser cutting, is suitable for your combination; the table below records order inputs and open questions, not an assertion of which process the supplier operates.

Limitations

Quoted tolerances are confirmed per drawing and order; do not assume one tolerance for every material, thickness, or geometry.
Feasibility review is not acceptance; the tolerance applied to your drawing is stated for the specific geometry.
Kerf, tool radius, edge distances, and finish rules depend on the specific material and geometry; ask which rules apply.

Evidence handling

Review date: 2026-08-26. Fact owner: Unassigned — owner approval required. Applicable grade: order-specific grades and drawings.

The date stated is the local draft evidence-gate review date, not a company fact-verification or department approval date. Ask in the RFQ which drawing-review, first-article, and material documents can be provided.

Ask in the RFQ whether a batch COA or material certificate can be provided with machined parts.

Company-declared, order-specific capability; confirm it with the quotation and approved drawing.
