CNC Machining in PMMA/Acrylic
PMMA/Acrylic plastic is a great alternative for glass in CNC machining processes like milling and turning relying on its notable natural properties such as excellent rigidity and transparency.
What is PMMA Plastic?
Polymethyl methacrylate, abbreviate as PMMA, also referred to as Acrylic, plexiglass, or perspex, is a thermoplastic possessing great stiffness and strength and is used in transparent sheet form. Its significant properties such as transparency, polishability, UV tolerance, flexural strength, and tensile strength set it apart from some materials like glass and polycarbonate. PMMA is readily machinable with the CNC machining technique to create lightboxes, billboards, signs, and other machined PMMA parts for chemical and construction fields. Interestingly, the hardness of PMMA can reflect its resistance to weather and high heat and the purity of raw material PMMA, and in turn, it can pose an influence on important issues of whether the plate will bend, deform, or shrink and whether the surface will be chapped in processing.
Mainly as a low-cost and lightweight glass substitute. Common applications include vehicle lamp covers and instrument dial covers.
It is determined by the desired effect and the titanium used. A tolerance of ±0.010” (±0.25 mm) is available at Runsom.
Optically clear, high impact resistance, excellent transparency, diverse colors and forms, UV-stability, and affordability.
It is mostly decided by the available machine and part geometry. A minimum wall thickness of ±0.03” (±0.8 mm) is available at Runsom.
As fast as 3 days, but it will be finally determined by part complexity and order quantity.
Max Part Size
200 x 80 x 100 cm(the available size is mostly decided by the machine and part geometry).
3-axis & 5-axis CNC milling.
Standard, Bead Blast, Custom Polishing.
PMMA/Acrylic CNC Machining Manufacturer – Custom CNC Acrylic Machined Parts
Runsom can offer several manufacturing technologies including CNC machining, injection molding, and 3D printing. Choosing Runsom for fabricating your PMMA components will be the right decision with firm assurance of high quality but low cost. We can flexibly handle different orders whose quantities range from 10,000 pieces of CNC PMMA products to one piece of prototype in a fast production cycle. While CNC machined Acrylic parts are relatively durable and versatile, this plastic is easy to fail and crack when suffering high compressive and tensile forces. Runsom has the capability to process fragile plastics carefully to avoid failure in the process of manufacturing, significantly decreasing the materials waste, saving costs, and then improving efficiency. What’s more, the accuracy of PMMA CNC parts can be ensured at high speed in Acrylic fabrication with our advanced multi-axis technologies. And if you have esthetic demands on your PMMA applications, a wide variety of surface finishing operations are available for your needs.
Acrylic CNC Machining Parts Applications
Acrylic is regarded as the secondary alternative for ceramics to make sanitary ware. It has extremely high brightness and has many more benefits, which set it apart from conventional ceramic materials. Some cases of points are great toughness, bright colors fitting diverse demands, greenness, and durability when it’s used in household items like toilets, bathtubs and basins, low costs, machinability, and lightweight. Therefore, products made from machined Acrylic are widely used in a multitude of industries and machinery accessories. Part of the common applications of Acrylic machining parts and molded components are as follows:
Medical: A variety of medical surgical instruments, baby incubators, etc.
Construction: soundproof door, telephone booth, window, etc.
Lighting: automobile lamps, chandeliers, fluorescent lamps, street lamp covers, etc.
Advertisement: exhibition rack, signboard, light boxes, etc.
Industrial: instrument cover and panel, etc.
Transportation: windows and doors of trains, cars, and other vehicles.
Our Strengths in CNC Acrylic Machining Services
- Ensure the workpiece is correctly fastened in case of vibration.
- Use a bit custom-designed to cut Acrylic.
- Cut through the Acrylic at a proper rate as rapidly and firmly as possible.
- Cool the acrylic for some time ahead of executing the cutting.
- Larger sizes of bit can perform better.
