Our Bead Blasted PMMA CNC Parts – PMMA combine accurate CNC machining with controlled bead blasting treatment. Since 2008, we've delivered custom acrylic solutions with tolerances as tight as ±0.02 mm for critical features. Our engineering team has worked in this field for more than 15 years and will work directly with you to improve designs and get a surface roughness of 1.6 to 3.2 μm after blasting. We guarantee consistent frosted finishes that get rid of machining marks and lower glare for prototypes that are ready in 3–7 days and for full production runs. We guarantee uniform frosted finishes that get rid of machining marks and lower glare for samples that are ready in 3–7 days and for full production runs.
You get more than just a surface treatment. The first step in our process is to carefully CNC cut and turn PMMA material. We use controlled bead blasting with small glass beads after the cutting. This gives all of your parts the same glossy look.
The blasting gets rid of tool lines that can be seen. It gives you a smooth, matte look that is polished and stays the same. Your parts become less reflective while keeping their skeletal integrity.
We change the settings of the blasting based on your needs. We can change the type of media and the pressure to meet your needs, whether you want a light frosting or a thicker thickness.

Our engineers review your drawings before production begins. You talk directly with experienced professionals—no intermediaries slowing things down.
We provide practical recommendations on material selection, wall thickness, and tolerance requirements. This approach helps you avoid common machining issues with PMMA, such as stress cracking or thermal deformation.
If your design needs adjustments for better manufacturability, we tell you early. This reduces errors and shortens your overall project timeline.
Bead blasting transforms the surface characteristics of your acrylic parts. It creates a uniform matte texture that hides minor imperfections from machining.
The frosted finish reduces glare and improves visual comfort in lighting applications. Your parts gain a premium appearance that stands out from standard clear acrylic.
Blasted surfaces also prepare components for secondary processes. If you plan to add coatings or printing, the textured surface improves adhesion.
The process has minimal dimensional impact. We maintain your specified tolerances while achieving consistent surface quality across all pieces in your batch.

We handle everything from single prototypes to large production runs. Your project receives the same attention to detail regardless of quantity.
For urgent needs, simple Bead Blasted PMMA CNC Parts – PMMA can be ready in as little as 3 days. Standard samples typically ship within 7 days after drawing approval.
We accept 100% custom orders based on your specifications. There are no standard products—every component is manufactured to your exact drawings.
Our quality control includes dimensional inspection before and after blasting. We check surface consistency and texture uniformity to ensure every part meets your standards.
Our bead blasted PMMA components serve multiple sectors:
The matte finish works well wherever you need to combine transparency with glare reduction and visual sophistication.
All raw PMMA materials come with certification. We follow international dimensional tolerance standards throughout machining.
For food-contact applications, we provide FDA-compliant material options. Surface treatment processes meet established standards for consistency and safety.
If quality issues arise within the same month of delivery, we arrange remanufacturing within one week. Shipping costs are fully covered.

Q: Can bead blasting be applied to CNC machined PMMA parts?
Yes, CNC milled, turned, or drilled PMMA (acrylic) components can undergo bead blasting to achieve uniform matte surfaces.
Q: Does bead blasting affect the transparency or optical properties of PMMA?
Bead blasting produces a matte surface, slightly reducing transparency but improving aesthetics and eliminating machining marks.
Q: What are the benefits of bead blasted PMMA parts?
Removes machining marks, provides uniform texture, reduces glare, and prepares the surface for polishing or coating.
