Plastic Machining

Precision CNC Machining of PMMA

Overview

Polymethyl methacrylate (PMMA), commonly known as acrylic glass, is widely used in numerous fields due to its high transparency, good mechanical properties, chemical corrosion resistance, and ease of processing. However, achieving high-precision CNC machining of PMMA is not an easy task. It has strict requirements for processing equipment, technology, and the technical level of operators. At Kansd, we create high-quality precision CNC machining services for PMMA based on in-depth research on PMMA materials and rich CNC machining experience.

PMMA Material Characteristics and Machining Challenges

PMMA has a light transmittance of up to 92%, which is more transparent than glass. At the same time, it has relatively high mechanical strength and can withstand certain external impacts. It has excellent weather resistance, and its physical and chemical properties are stable under different environmental conditions. However, during the CNC machining process, PMMA is prone to problems such as surface scratches, thermal deformation, and stress cracking. For example, if the heat generated during processing cannot be dissipated in time, the local temperature of the material will be too high, resulting in deformation and affecting the machining accuracy and surface quality.

Kansd's Unique Advantages in PMMA Machining

With years of in-depth involvement in the industry, Kansd has overcome the difficulties in CNC machining of PMMA and developed an effective processing technology, bringing many advantages to customers:

1.

Excellent Surface Quality

By optimizing the tool path and rationally selecting cutting parameters, we can effectively avoid the generation of surface scratches and burrs. The surface of processed PMMA parts is as smooth as a mirror, and the surface roughness can reach below Ra0.8μm, meeting the requirements of application scenarios with extremely high surface quality requirements.

2.

High-Precision Assurance

We have introduced advanced five-axis 联动 CNC machines and, combined with professional programming software, can achieve high-precision machining of complex shapes. The dimensional accuracy is controlled within ±0.01mm, ensuring the consistency and interchangeability of parts.

3.

Diversified Processing Services

We can not only perform conventional processing operations such as milling, drilling, and cutting but also provide special processing techniques such as laser engraving and thermoforming to meet the diverse needs of customers.

PMMA-Machined Parts Suitable for Multiple Fields

Due to the unique properties of PMMA materials, their machined parts play an important role in multiple industries:

Advertising and Decoration Industry

The high transparency and ease of processing of PMMA make it an ideal material for manufacturing light boxes, signboards, and display racks. The PMMA advertising products we process have beautiful shapes and bright colors, which can effectively attract the attention of consumers.

Optical Instrument Industry

In the field of optical instruments, high requirements are placed on the optical properties and dimensional accuracy of materials. Optical components such as lenses and prisms processed from PMMA can meet the precise requirements of optical systems for light refraction and reflection.

Electronic Product Industry

PMMA can be used to manufacture electronic product components such as mobile phone screen protectors and tablet computer casings. It can not only enhance the appearance texture of products but also provide good protection performance.
