Quick Answer

CNC laser cutting at H-O Products follows your CAD path through thin material with no die to build, holding detail that hard tooling cannot. It is the right process for Kapton® polyimide, APTIV® PEEK film, thin dielectric films, and features below roughly 0.020″ that a die cannot hold. Tolerance runs about ±0.002″ to ±0.010″ and thickness about 0.0005″ to 0.125″, depending on material and geometry.

Materials are selected for laser compatibility and confirmed per material: some films cut cleanly, others are better die- or knife-cut. For thicker stock and volume H-O points to die cutting, and for soft or large parts to knife cutting. All under an ISO 9001:2015 certified quality management system in Winsted, Connecticut. See the process strip for lead-time and ordering details.

When To Spec What
  • Film insulators: Kapton® and APTIV® PEEK cut into fine-feature dielectric insulators and barriers
  • Intricate flex & film parts: outlines with slots and holes below what a die can hold, straight from the CAD file
  • Fine gaskets in thin film: internal features a die blade cannot resolve
  • Prototypes of intricate film parts: first articles with no tooling commitment
  • Thicker stock or volume: die cutting; soft, thick, or large parts: knife cutting
  • Non-laser-suitable chemistries: confirmed per material and routed to die or knife cutting instead
What we do

Laser cutting, converted in-house

CNC laser cutting uses a focused laser, guided directly from your CAD file, to cut thin engineered materials with very fine detail. There is no shaped tool to build first, and the narrow beam resolves slots, webs, and small holes that a die blade cannot. H-O performs it in Winsted on materials selected for laser compatibility, then integrates finishing in the same workflow.

H-O cnc-laser operation overview, small custom image

What makes the operation different is the depth of the material inventory and the material knowledge behind it. We stock materials from Rogers Corporation, Saint-Gobain, Henkel/Bergquist, DuPont, NeoGraf, Kaneka, Victrex, and dozens of other suppliers. Not every material is appropriate for a laser: some chemistries are not laser-suitable, so material selection and parameters are confirmed per material before cutting. When an engineer specifies Kapton® HN or APTIV® PEEK, we already know how it responds and which parameters hold the cleanest edge.

In-house vs sourced

Laser cutting of laser-compatible thin films and fine-feature parts is performed in Winsted, CT. For thicker materials and production volume, we typically recommend flatbed die cutting; for soft, thick foams and large-format parts, CNC knife cutting; and for acrylic foam tapes at high volume, rotary die cutting. Material suitability for the laser is confirmed per material. See the process comparison below.

Thin films and fine features a die cannot hold

1

Thin dielectric films

Kapton® polyimide, APTIV® PEEK, and thin dielectric films down to about 0.0005″ cut cleanly with a focused beam, where a die blade would distort or drag the film.

2

Features below 0.020″

Fine slots, narrow webs, and small holes below roughly 0.020″ that a steel-rule, machined, or matched-metal die cannot resolve. The narrow kerf is the whole point.

3

Intricate flex & insulator parts

Complex insulator outlines, flex-circuit support layers, and high-detail patterns where the geometry is too intricate to tool economically, and tolerance to about ±0.002″–0.010″ is needed.

Material compatibility comes first

The laser is the right tool only when the material is laser-compatible. Many thin films and engineered insulators cut well; some chemistries are not laser-suitable and are better die- or knife-cut. Send the grade and thickness and we confirm laser suitability and parameters before committing to the process. For thicker or higher-volume parts, die cutting is usually the better answer.

Guidelines that hold fine features and edge quality

Designing parts for laser cutting means matching geometry and material to the beam. Following these rules before drawings are finalized prevents rework; our engineering team reviews every part for manufacturability first.

Confirm laser compatibility first
Material chemistry decides whether the laser is appropriate at all. Some thin films and insulators cut cleanly; others are not laser-suitable and are better die- or knife-cut. We confirm suitability and parameters per material before quoting the process.
Fine features are the reason to use a laser
Slots, webs, and holes below roughly 0.020″ that a die cannot resolve are exactly where the laser wins. Tolerance on these features runs about ±0.002″ to ±0.010″, depending on material, thickness, and geometry.
Thickness range
Best suited to thin material, roughly 0.0005″ to 0.125″. Above this range a die or knife is usually the better and faster process; confirm at drawing review.
Minimum feature and spacing
The narrow kerf supports small features and tight spacing, finer than die tooling allows. Hold a sensible minimum web for the material so thin sections do not curl or distort; we will advise the practical limit per material at review.
Edge condition
Laser-cut edges are clean and square on compatible films. Edge condition is material-dependent, so where edge appearance is critical, call it out on the drawing and we will set parameters to suit.
Design file requirements
DXF or DWG preferred for the cut path; PDF with dimensions for inspection criteria; STEP and IGES accepted for 3D reference. Include material callout and thickness, critical-dimension tolerances, edge-quality requirements, and quantity expectations.

FAQ

CNC laser cutting questions

Common questions from engineers speccing laser-cut parts.

5 questions

What is CNC laser cutting used for?

Laser cutting is for thin films and fine features that a die cannot hold: Kapton® polyimide, APTIV® PEEK, thin dielectric films, and detail below roughly 0.020″. A focused beam follows your CAD path with no die to build, holding intricate geometry on laser-compatible materials. For thicker stock and volume, die cutting is the better process.

When does laser cutting win over die cutting?

Laser wins when the part is thin, intricate, and made of a laser-compatible material, especially for features below roughly 0.020″ that a steel-rule, machined, or matched-metal die cannot resolve, and for thin films a die blade would distort. A die wins on thicker material and at production volume, where it is faster per part and lower total cost.

What tolerance can laser cutting hold?

About ±0.002″ to ±0.010″ on thin film, depending on material, thickness, and geometry. Tighter values are achievable on the right material and feature; we confirm the realistic tolerance for your part during drawing review.

What thickness range suits laser cutting?

Laser cutting is best on thin material, roughly 0.0005″ to 0.125″. Above that range a die or knife is usually faster and lower total cost, so we recommend the process that fits the thickness and volume rather than forcing the laser onto thick stock.

Which materials can H-O Products laser cut?

Laser-compatible thin films and insulators from the inventory, including Kapton® polyimide, APTIV® PEEK, and thin dielectric films and papers. Not every material is laser-appropriate: many soft foams and thick elastomers are better die- or knife-cut, and some chemistries are not laser-suitable. We confirm suitability per material before quoting the process.
