Key Takeaways
- Plexiglass fabrication (PMMA) delivers glass-like clarity with superior impact and weather resistance.
- Acrylic is easy to machine and from, even with woodworking tools when protected.
- As a thermoplastic, it supports heat bending and thermoforming for complex shapes.
- Lightweight sheets are durable for transport and everyday use; ideal for partitions, displays, and enclosures.
- Use generous cold-bend radii and anneal bonded parts to reduce cracking/crazing.
Understanding plexiglass fabrication and forming is the first step in deciding if it’s the right plastic product for you. Fortunately, Polymershapes is an expert in the fabrication and formation of plexiglass.
We’re here to explain the process and answer all of your questions. Feel free to reach out to us to discuss your next product, too. We can help you determine whether plexiglass is the right plastic for you (and often, it is!).
The 411 on Plexiglass
The first thing that you should know before we discuss plexiglass fabrication is its proper name, which is Acrylic Polymethyl Methacrylate, or PMMA. It’s also known as Acrylic Plexiglass. There are a variety of branded names, but they all mean the same thing.
Fabrication itself is effortless because plexiglass is incredibly easy to form. It can even be formed with traditional woodworking tools, as long as you take care not to scratch it.
We have the tools necessary to get the job done, allowing for plexiglass fabrication into sheets of nearly any shape.
Advantages of Plexiglass
Since plexiglass is a thermoplastic, it can also be thermoformed. That increases its versatility by a large margin.
Plexiglass provides a brilliant clarity which is fittingly as clear as glass. However, because it is resistant to impact and weather, it’s considered much more practical than glass, which can break and shatter.
Plexiglass is also a lightweight material. That, too, makes plexiglass forming into different shapes very easy. It’s ideal for transportation, as well. Fortunately, because it’s a durable material, there’s little worry about damage.

Frequently Asked Questions
Can plexiglass be cold-bent during fabrication, and what’s the tightest radius?
Yes. For many grades, the minimum cold-bend radius is about 330× the sheet thickness. Tighter thicknesses require heat forming.
Should annealing be done before/after bonding?
Anneal before solvent-bonding to relieve stress and reduce crazing risk. Consider a post-bond anneal to strengthen joints; heat around 1800F for about 1 hr per mm thickness, then cool slowly.
Is plexiglass suitable for food-contact components?
Certain acrylic grades carry FDA food-contact listings with restrictions, yes. But we, at Polymershapes, help you verify compliance for the specific sheet used.
How do you handle residue in plexiglass fabrication?
Keep masking on during most operations; remove soon after install. If the adhesive hardens, aliphatic naphtha/hexane/kerosene can soften it; then wash off any oily film. Avoid sharp scrapers.
