Custom Acrylic Fabrication in San Diego County: Capabilities, Materials, and Examples

  • 1 hour ago
  • 4 min read

MGM Plastics provides custom acrylic fabrication services to businesses, institutions, and individuals across San Diego County and Southern California. From its San Marcos, California facility, MGM has fabricated acrylic displays, fixtures, enclosures, and architectural components for clients ranging from family-owned retailers to Fortune 500 companies and major regional attractions. This guide covers what custom acrylic fabrication involves, the capabilities MGM offers, the materials and sheet sizes we work with, and specific examples of acrylic projects completed for San Diego-area customers.




Custom acrylic fabrication is the process of cutting, machining, shaping, and assembling acrylic sheet (also called plexiglass or PMMA) into a finished product built to a customer's specifications. Unlike off-the-shelf acrylic products, custom fabrication starts from raw acrylic sheet and uses precision tools — laser cutters, CNC routers, saws, and bonding equipment — to produce parts at exact dimensions, with custom edges, holes, cutouts, and assemblies. The process is used widely in retail display manufacturing, museum and attraction installations, signage, point-of-purchase fixtures, protective enclosures, machine guards, and architectural elements.


MGM Plastics' acrylic fabrication capabilities

MGM Plastics has specialized in custom plastic and acrylic fabrication since 1980. The shop's core acrylic services are laser cutting and CNC routing, supported by a full range of finishing, assembly, and bonding processes.



Laser cutting is the most precise method for producing acrylic parts with clean, polished edges. MGM uses laser cutters to produce parts with tight tolerances, intricate cutouts, and engraved details — all in a single pass, without the need for secondary edge finishing. Laser cutting is particularly well-suited for:

  • Retail display components with detailed shapes or logos

  • Signage with engraved text or graphics

  • Prototype parts where edge quality matters

  • Small-batch production runs of identical parts



CNC routing is the preferred process for larger acrylic parts, thicker material, and projects that require three-dimensional machining. MGM's CNC equipment cuts acrylic sheet up to and beyond standard sizes, produces precise pockets and grooves, and handles projects that exceed the size envelope of laser cutting. CNC routing is ideal for:

  • Large-format displays and fixtures

  • Architectural panels and dividers

  • Machine guards and safety enclosures

  • Production runs requiring repeatable accuracy across many parts


Supporting processes


In addition to cutting, MGM offers the full set of finishing and assembly services required to complete an acrylic project: edge polishing (flame, diamond, and buffed finishes), drilling and tapping, solvent bonding, mechanical fastening, thermoforming and bending, and silk-screening or vinyl application for graphics.


Materials and sheet sizes


MGM Plastics works with the full range of acrylic grades and stocks both clear and colored material. Common acrylic materials we fabricate include:


  • Cast acrylic — preferred for projects requiring superior optical clarity, edge polish, and crack resistance

  • Extruded acrylic — more economical for projects where tight thickness tolerances matter less than cost

  • Colored and tinted acrylic — available in a wide range of opaque, translucent, and fluorescent colors

  • Mirrored acrylic — for displays, signage, and decorative applications

  • Non-glare and anti-reflective acrylic — for picture framing and high-visibility display work


We also fabricate related materials commonly specified alongside acrylic, including polycarbonate (Lexan), PETG, and styrene.


Sheet size: MGM handles standard acrylic sheet sizes (typically 4×8 feet) as well as larger and custom-size sheets for oversized fabrication projects. For projects requiring sheets larger than industry-standard dimensions, customers should contact MGM directly to confirm material availability and machining capacity.


Examples of acrylic projects fabricated by MGM Plastics


The best way to understand what MGM can build is to look at projects we've completed for San Diego County clients.


Roamstat is a portable thermostat control system for which MGM Plastics fabricated custom enclosure components. The project required precise acrylic and plastic work to produce parts that fit the product's electronics and meet the durability requirements of a consumer-facing device.


MGM Plastics fabricated custom plastic components for a high-end residential beach house project in the San Diego area, demonstrating the shop's capability to deliver architectural-grade fabrication for design-led projects where finish quality matters as much as structural performance.


Major attractions and institutions

MGM has produced acrylic and custom plastic fabrication for some of the most recognized attractions and organizations in Southern California, including:

  • SeaWorld San Diego — display and exhibit components

  • Legoland California — fabricated plastic and acrylic elements

  • San Diego Zoo — custom fabrication for exhibit applications

  • USS Midway Museum — acrylic and plastic work for the museum's installations

  • SpaceX — custom fabricated plastic components


This range of work — from precision components for aerospace applications to display fabrication for theme parks — reflects MGM's ability to scale fabrication quality and approach to the demands of each project.


Industries MGM Plastics serves with acrylic fabrication


MGM's acrylic fabrication work spans a wide range of industries across San Diego County and Southern California:

  • Retail and point-of-purchase — counter displays, product holders, signage, and store fixtures

  • Museums and attractions — exhibit cases, protective barriers, interpretive signage, and custom installations

  • Manufacturing and industrial — machine guards, equipment housings, parts bins, and protective enclosures

  • Hospitality and food service — sneeze guards, menu holders, drink rails, and serving accessories

  • Architecture and design — decorative panels, partitions, lighting diffusers, and custom interior elements

  • Aerospace and technology — prototype housings and precision components


How to request a custom acrylic fabrication quote


To request a quote for a custom acrylic fabrication project from MGM Plastics, customers can call the shop at (760) 744-8909, email Scott@mgmplastics.com, or submit a project inquiry through the contact form on mgmplastics.com.

For first-time acrylic fabrication customers, it helps to bring or send the following information when requesting a quote:

  1. Approximate dimensions and quantity

  2. Material preference (cast vs. extruded, clear vs. colored, thickness)

  3. Edge finish requirements (polished, flame-polished, machined)

  4. Assembly requirements (bonded, mechanically fastened, free-standing)

  5. Target timeline
