Acrylic, or PMMA, is a transparent thermoplastic with amazing strength and optical clarity. Moreover, the material is similar in attributes to polycarbonate. Though it shows lower impact strength, it still shows 10-24 times more impact resistance than glass.

CNC machining acrylic is a widely used procedure for the material due to its versatile properties and stability under several conditions. Commonly, it is used in the automotive and medical industries.

At Tenghui, we use modern techniques and the latest technology to ensure top-notch and reliable products. From manufacturing rapid prototypes to refined finished products, we are committed to giving customized and risk-free solutions.

Typically, acrylic sheets have glass-like qualities, like brilliance and clarity- but almost half of the weight and more impact resistance than glass. The main characteristics of acrylic are briefly stated as follows:

• Great light transmission and optical clarity properties
• More abrasive resistant as compared to aluminum
• Impressive chemical resistance
• Cost-effective and readily available
• Flexible and shock resistance as compared to glass
• UV resistant
• Available in a variety of colors
• Recyclable

CNC machining acrylic is one of the most prominent and used processes for producing acrylic parts; many industries use various manufacturing processes to ensure the precise production of acrylic parts. We offer the following acrylic machining services:

• Milling

CNC milling is a precise and accurate method due to the presence of a multi-point cutting tool that can move along multiple axes. It enables cutting from different angles and is perfect for hard materials like acrylic. Currently, many industries are using the CNC milling process to cut acrylic materials to achieve desired shapes and optimal handling strength.

• Turning

Technically, CNC turning is a process that involves holding the workpiece and rotating it along the cutting tool until the desired shape and design are formed. It is also known as subtraction machining. Furthermore, the CNC turning process helps conduct various operations, including boring, parting, drilling, knurling, facing, and grooving.

• Engrave

Engraving uses computer-controlled machines for the carving of hard materials. Additionally, milling paths are generated by CAD software based on the drawing to be designed. In addition, the process is useful for precision engraving as it has reduced the chances of errors, whether for artistic or practical purposes.

• Drilling

It is a CNC machining process that uses a rotating cutting tool to produce round holes in the stationary workpiece. Typically, these holes are made for the accommodation of molts and screws. However, the process is also used for aesthetic purposes depending on the nature and design of the components.

• Painting

Generally, a smooth and shiny surface finish is given by the painting of the product. Painting offers a wide range of colors and allows designers to manufacture eye-catching products with custom blends.

• Silk Screen Printing

The silk screening painting method requires using stencils to paint the acrylic products. The stencil is placed on the workpiece and printed with ink -a porous mesh frame supports these stencils. Ideally, the process is best suited for graphic and bold designs.

• Polish

For the best, most smooth, and refined final products of acrylic, the polishing is done on the edges or corners of the products. A polishing paste is applied on the edge of the piece and gently works with the buffing pad with light pressure. With gentle movement and little effort, the acrylic products become crystal clear and transparent.

In the modern era, acrylic components are widely used in various industries due to their transparency and impact resistance characteristics. Some major applications of acrylic across multiple sectors are as follows:

• Glass Alternative

Acrylic components are generally used as the glass alternative due to their more impact resistance properties than glass, making them reliable and robust. It is used in the manufacturing of aquariums and for submarine windows in the marine industry.

• Medical Devices

Acrylic plastic is typically used to make various medical devices due to its resistance to cracking and breaking. They are also helpful for producing test equipment like beakers and vials and surgical instruments like catheters and implants due to their high performance.

• Lighting and Electronics

Fluorescent lights have come under scrutiny as they emit a large amount of blue light, which can cause depression and mental illness. Acrylic plastic has been used recently to manufacture these light bulbs to eliminate blue light. In addition, they are also utilized in making molded products, wire and cable insulation, adhesives, circuit boards, and encapsulants.

• Consumer Products

Many safety products and other consumer safety products, like helmets, are made of acrylic plastic due to increased stability and resistance properties. Furthermore, they are also used in lenses, acrylic nails, LCD screens, and paint.

• Automotive Industry

Due to superb electrical and chemical resistance, it is used to manufacture several automotive parts, including bumpers, carpet fibers, and cable insulators.

• Construction Industry

Acrylic plastic is also used in the construction industry to manufacture and improve the aesthetic of buildings as an alternative to glass. Consequently, they are also helpful for making panel materials, signage, floorings, opaque cladding, shower trays, baths, asphalt, and many more.

Designing CNC machined acrylic parts can be tricky if design limitations are not followed carefully. Before proceeding with the manufacturing of acrylic parts, keep the following tips in mind:

• Acrylic is brittle; therefore, it is ideal to avoid sharp corners from the inside.
• The parts can be conveniently connected with special adhesives, screw metal, or machine screws at corners.
• Request the corners and edges to be polished to achieve a glass-smooth finish.
• It is better to avoid deep holes as drilling can be a bit challenging.
