Materials Commonly Used in Custom Plastic Fabrication

Choosing the right plastic material is critical to achieving its functionality, aesthetics, and longevity. We have great experience at Welch Plastics and are happy to share our knowledge on the best plastic material for your application.

✅ Acrylic (PMMA)

• Lightweight, optically clear, impact resistant
• Great for display cases, signs, and sneeze guards
• Now offered in a range of colors and surface textures.

✅ Plexiglass

• Brand name and is predominantly referred to as acrylic
• Great UV resilience
• In contrast to acrylic, used primarily for aquarium applications, windows, or as barriers.

✅ Polycarbonate (PC)

• Stronger than acrylic and has greater impact resistance
• Great options for guards and other safety barriers

✅ ABS (Acrylonitrile butadiene styrene)

• Good strength and longevity
• Used most commonly for enclosures and automotive and consumer electronics components.

✅ PVC (polyvinyl chloride)

• Good weather-resistant and chemical-resistant
• Used most commonly for piping, signage, and applications that are located outdoors

Fabrication Processes

Some projects lend themselves to a certain process. As a full-service plastic manufacturer based in Las Vegas, we have multiple fabrication processes to meet your needs.

1. CNC Machining

Computer-controlled allows for ultra-accurate cuts and contours. Great for :

• Mechanical components
• Precision enclosures
• Complex 3D parts

2. Laser Cutting & Engraving

Great for fine detail and sharp edges. Often used for:

• Acrylic signs
• Logo cutouts
• Custom branding

3. Thermoforming

Heated plastic sheets are shaped into molds. Applications include:

• Plastic trays
• Automotive panels
• Custom enclosures

4. Injection Molding

Best suited for high volume production. Advantages include:

• Consistency over high volume
• Fast speed of production
• Durable strength for many uses

5 Vacuum Forming

The heated plastic sheet is drawn over a mold using suction. Used for:

• Custom casings
• Lightweight packaging
• Decorative purposes
