Acrylic CNC Machining
Acrylic, also known as PMMA (Polymethyl methacrylate), is a rigid, transparent plastic material with outstanding strength, stiffness, and optical clarity.
Acrylic is a material that resists scratches. It’s frequently used in tanks, panels, and optical applications. Clear acrylic will appear more frosted than transparent when machined, but several finishing techniques can smooth it back to an optically clear state.
Features of Acrylic plastic :
The light transmittance is above 92 percent, with transparency that resembles crystal. This material has a higher light transmittance than glass and other polymers.
High surface hardness and surface gloss. Acrylic has excellent scratch resistance.
Acrylic has good processing performance.
Wear-resistant and corrosion-resistant. Most laboratory chemicals’ aqueous solutions do not affect acrylics.
Acrylic Properties
| Tensile Strength | Elongation at Break | Hardness | Density | Maximum Temperature |
|---|---|---|---|---|
| 8,000 PSI | 6% | Rockwell M95 | 1.19 g/㎤ 0.043 lbs / cu. in. | 170° F |
CNC machining
Due to its unique qualities, PMMA is appropriate for applications requiring the greatest accuracy and surface smoothness. CNC machining is always the perfect solution for acrylics. Precision machining acrylics plastic allows for creation of complex, high-tolerance parts with excellent mechanical properties and accuracy.
RpProto offers 3-axis and 5-axis CNC acrylics plastic machining services, including milling and turning. It can efficiently produce components in both prototyping and large-volume runs.
Applications of Acrylic Plastics
Many industries use a wide variety of acrylic products. These industries include:
Automotive Industry:
These include interior light covers, indicator light covers, and others. It is a fantastic option for auto manufacturers due to its exceptional formability and surface toughness.
Lighting and Electronics:
Acrylics maximize LED lights’ ability to generate light. It’s excellent for lamp production due to its transparency and optical characteristics. Also, it has a high level of light transmission. Acrylics are scratch-resistant and optically clear.
Medical and Healthcare:
Acrylics are pure and easy-to-clean materials. They can therefore be used to create incubators, cabinets, and medical equipment in hospitals. They are also highly compatible with biologics. They are, consequently, good options for tooth cavity fillings.
Some of the most common products you can make from acrylic sheets include:
- Glove boxes
- Displays and signs
- Lighting fixture lenses
- Aircraft glazing
- Desiccators and dry boxes
- Car lights, light tubes
- Radiation shields
- Sinks, knobs, batons, and baths
- Retail fixtures
- Windows and glass alternatives
- Automotive components, including fascia panels, steering wheel, and badges
