Mastering Laser Cutting: Your Go-To Solution for Precision and Efficiency
Adopting laser cutting for your fabrication processes is only natural. As an ultra-precise, high-performance, and highly scalable process, organizations are turning to laser cutting daily. From signage to structural parts, laser cutting is changing how people from different industries approach custom plastic fabrication, plastic manufacturing, and even prototyping, in a design-driven, high-tempo world.
If you’re looking for a reputable plastic manufacturer in Las Vegas with advanced laser cutting capabilities, this guide will give you the process, benefits, applications, and reasons why Welch Plastics is a great partner for precision manufacturing.
What is Laser Cutting?
Laser cutting is a fabrication process that utilizes a focused and powerful laser beam to cut, engrave, or etch materials. Laser cutters, unlike traditional mechanical cutting tools, do not come into contact with the material; they vaporize or melt the material using concentrated energy.
Benefits of contactless laser cutting include:
- Pinpoint accuracy for detailed cuts and complex shapes
- Smooth, sealed edges needing little to no post-processing
- Speed - perfect for scale jobs or fast-turn jobs
From acrylic display cases to custom electronic enclosures, laser cutting can provide solutions to any industry, from aerospace to retail.
How Laser Cutting Works
CAD (Computer Aided Design) files are the foundation of all laser cutting. A CAD file will be the path the laser beam follows to cut, mark, or engrave the plastic material.
Of all mechanical plastic manufacturing and fabrication, laser cutting plastic offers some of the most efficient and precise manufacturing methods. Here's what it looks like:
- A laser cutting machine utilizes a directed high-energy laser to the surface of the plastic.
- The material either vaporizes or instantly melts along the cut path.
- The result is a clean and sealed edge, with minimal waste.
Common types of plastics we work with are:
- Acrylic (PMMA)
- Polycarbonate (with precautions)
- PETG
- ABS
- HDPE.
Note: Not all plastics are laser-cut safe. PVC, for example, emits toxic chlorine gas when cut.
Customer signs made by laser cutting
Laser cutting plastic allows for extreme precision and accuracy which is important when making exacting pieces like the helmet cover below made for the Mclaren store Wynn Resorts and the display made for the Las Vegas Golden Knights.
Advantages of Laser Cutting in Plastic Fabrication
Laser cutting offers many competitive advantages, whether you are designing a one-off prototype or scaling up to mass production.
1. Unmatched Accuracy
Laser cutters can achieve tolerances of .001 inches with ease. Therefore, they are ideal for:
- Medical devices
- Aerospace parts
- Enclosures for electronics
- Custom logos and engravings
2. Design Flexibility
Since you are using digital CAD files, designs can easily be amended or updated on the fly. Laser cut designs can feature intricate curves, detailed cut-out patterns, meaning geometries and designs that would not have been possible using older methods of cutting.
3. Compatible with Many Materials
Laser cutting is not limited to plastics; it is also effective with:
- Wood
- Metals
- Composites
- Fabrics
- Glass (for engraving)
Because of this flexibility, laser cutting is the preferred option in many industries.
4. Faster Lead Times
When compared to CNC routing or manual cutting, laser cutting is considerably faster, making it a preferred option for low-volume or high-volume production.
5. Cost-Efficient
With low material waste, no tooling costs, and low labour costs, laser cutting can offer excellent ROI. Especially when used for custom plastic fabrication as support components for larger injection molded components.
Uses of Laser Cutting in Plastic Manufacturing
Because of the flexibility of laser cutting, it is an integral part of modern plastic manufacturing. Consider these options:
• Retail Signage & Branding
The sharp edges and intricate designs of laser-cut acrylic allow us to offer a great solution for…
- Storefront logos
- POP displays
- Directional signage
• Prototypes & Custom Enclosures
Are you looking to test a new idea? Laser cutting can allow you to prototype something quickly and at very little cost with no commitment to tooling.
• Architectural Elements
We can produce light, intricate panels and custom elements for your next interior design project or model.
• Industrial Parts & Fixtures
We have seen a lot of applications developed for heavy-screen or close-tolerance gaskets, brackets, and housing that could go right into the manufacturing line.
• Awards, Gifts, Promotional Products
Personalize corporate gifts, awards, and branded merchandise with laser etching.
Laser Cutting vs. Injection Molding
Now this brings up the question that many of our clients are asking us lately, 'Is laser cutting better than injection molding?' And while this might seem simple, the answer is complicated because there are different issues to evaluate depending on what we are trying to accomplish.
| Features | Laser Cutting | Injection Molding |
| Setup Cost | Low | High (there is a beginning commitment to mold the part) |
| Best Suited for | Prototypes & small runs | Mass production |
| Flexibility | Customizable | Fixed once the mold is created |
| Lead time | Fast | Moderate - Long |
| Design Changes | Easy | Potentially Expensive - time-consuming |
👉 Laser cutting is the right solution for shorter run jobs that need a fast turnaround or need fast custom fabrication at a low cost.
👉 Injection molding is the right solution for production that is high volume and of consistent quality.
At Welch Plastics, we offer both laser cutting and injection molding, and we will help you find the best solution for you based on your timeline, budget, and end use.

Steps to Prepare Your Laser-Cut Designs
1. Create a CAD File
Use your preferred CAD software (i.e., AutoCAD, Illustrator, and SolidWorks) to create your design, then save your CAD file in a compatible format for laser cutting (i.e., DXF, DWG, and AI).
2. Choose the Material you want to use.
- Determine the strength of your plastic.
- Determine how transparent you want your plastic.
- Choose your color.
- Determine the heat resistance needed.
3. Optimize your design to be cut.
- Remove complex design details that are not shown in the original design.
- Avoid double lines.
- Make sure you close your paths for vector cutting.
