Acrylic Description: What is PMMA?

Acrylic, also known as PMMA or Plexiglas, is a transparent plastic material. It is an organic polymer compound, made from methyl methacrylate monomer (MMA) by polymerization. This material has excellent transparency, chemical stability and weather resistance, as well as easy processing and coloring properties. As a result, acrylic has a wide range of applications in many fields such as construction, advertising, furniture manufacturing, and transportation.

Acrylic parts machining process

machmaster provides the expertise and experience to ensure machining quality and efficiency. Through reasonable process selection and fine operation, high quality and high precision acrylic parts can be produced.

CNC machining Acrylic

According to the shape design requirements of acrylic products, acrylic sheets and rods, reduce the material processing, the formation of different shapes of graphics.

Acrylic Polishing

After the engraving is completed, the edges and surfaces of the acrylic parts are polished to eliminate rough edges and increase the smoothness and aesthetics of the parts.

Hot Bending

The acrylic material is heated to a specific temperature and then bent to the desired shape according to the dimensional requirements of the part.

Pasting and assembly

Depending on the requirements of the acrylic parts, if a taping and assembly operation is required. It is necessary to use a non-marking adhesive or a suitable adhesive to stick the parts together precisely.

What are the acrylic surface treatment methods?

Frosting treatment

The surface of the acrylic plate will be polished and then rubbed with sandpaper or grinding wheel to achieve a certain abrasive effect to make the surface smoother, and the light passing through the abrasive surface will produce a soft scattering effect.

Hot bending

The use of hot processing steel mold will be flexible acrylic sheet processing, making arc, sphere and other complex shapes, and can reduce the rupture rate of acrylic sheet to a certain extent.


If you want the surface of the product to be bright, you can apply liquid polishing wax and wipe evenly with a soft cloth to achieve the effect.

silkscreen printing

The pattern to be silk-screened (such as LOGO, publicity diagram, advertising slogan, etc.) is printed on the stencil, and then the acrylic products are placed under the silk-screening stencil, and the ink is printed on the acrylic crafts across the stencil.While four-color screen printing is used to print patterns composed of multiple colors, such as complex logos or publicity graphics


Acrylic painting surface treatment includes grinding, polishing, spraying, dust removal and other steps, can change the appearance and performance of the acrylic surface.


Fine sand particles are sprayed onto the acrylic surface by a high-speed airflow to create a variety of effects such as frosted, frosted ice flowers, frosted violets, and more.
