The choice of finish depends on the intended use of the product. For example, in the automotive industry, exterior components often have a glossy finish to enhance their visual appeal, while interiors utilise a dull finish to limit distractions for the driver. Similarly, in the construction industry, plastic finishing techniques aim to embellish plastic elements, improving their appearance and perceived value. This is particularly important when plastic is used for furniture or building components, where an attractive finish can elevate the overall aesthetics.
Plastic finishing techniques vary depending on the product and the desired effect. For instance, spray coating is a popular method for decorating plastic products, offering customisation and an attractive finish. Another technique is excimer matting technology, which can create a deep matt finish on plastic panels while reducing nitrogen consumption and costs. Flame polishing is another effective method, particularly suitable for flat, external surfaces made of acrylic, as it provides a clear and smooth finish.
Overall, plastic finishing is a crucial step in the manufacturing process, allowing fabricators to enhance the visual appeal, functionality, and perceived quality of plastic products. By selecting the appropriate finish, manufacturers can ensure that their products not only serve their intended purpose but also captivate consumers with their improved look and feel.

There are twelve grades of plastic finish, ranging from dull to matte, semi-gloss, and shiny
Plastic finishing refers to the process of applying different techniques to give a plastic product a specific look and feel. This can involve moulding the plastic to have a certain texture or finish, or using abrasives and polishes to achieve the desired result. The finishing process can also serve to embellish plastic elements, enhancing their perceived value.
Dull finishes are characterised by their lack of gloss or sheen, resulting in a more understated appearance. They are commonly used in industrial applications where a non-reflective surface is preferred, as they reduce glare and hide fingerprints, scratches, and other imperfections. Dull finishes are ideal for parts that are frequently handled or exposed to wear and tear, such as industrial components or screen bezels.
Matte finishes have a low shine and a slightly rough texture compared to semi-gloss or shiny plastics. They are often used in consumer electronics and automotive interiors, providing a sophisticated aesthetic while reducing glare and concealing imperfections. The tactile nature of matte finishes also enhances grip, making them suitable for handheld products.
Semi-gloss finishes offer a middle ground between matte and glossy, providing some reflectivity while maintaining a functional appearance. They are commonly used in household appliances, office equipment, and automotive interiors. These finishes are created using different levels of grit sandpaper, resulting in a smooth but not perfectly smooth surface.
Shiny finishes, on the other hand, have a perfectly smooth and highly reflective surface, often created using diamond powder in oil. These finishes are used when a high level of visual impact and vibrancy is required, such as in luxury goods or plastic mirrors.
Each grade of finish has its own unique characteristics, and the choice of finish depends on the specific requirements of the product and its intended use.

Matte finishes are created using a fine stone powder polish and are used for internal parts
Plastic finishing is an important process that enhances the aesthetic appeal and functionality of plastic products. It involves applying various treatments to the surface of plastic items to achieve a desired look and feel. Finishes can range from highly polished, mirror-like surfaces to matte, satin, or textured finishes, depending on the intended use and customer preferences.
Matte finishes, in particular, are created using a unique process that results in a non-reflective, dull surface. This finish is achieved by polishing the plastic surface with a fine stone powder. The stone powder creates a uniform texture that effectively reduces the reflection of light, giving the plastic a matte appearance.
The use of stone powder polish is an economical and effective method for achieving a matte finish. It ensures that any tooling, molding, or machining marks are no longer visible on the final product. This makes it ideal for internal parts of products or components where the appearance is of minimal importance.
Matte finishes created with stone powder polish are commonly used in the automotive, construction, and consumer goods industries. These finishes are often applied to interior components, such as dashboards, door panels, or appliance housings, where a non-reflective surface is preferred.
Maintaining a matte finish requires specific care. Unlike glossy finishes, matte surfaces cannot be corrected or polished without ruining the matte effect. Therefore, cleaning with pH-neutral, wax-free soap and frequent washing are essential to prevent contaminants from building up and altering the finish.

Finishing processes include spray coating, wrapping, industrial digital printing, drying, and curing
Plastic finishing is an essential step in the plastic fabrication process, which enhances the product's visual appeal and functionality. Finishing processes such as spray coating, wrapping, industrial digital printing, drying, and curing are used to achieve the desired look and feel of the final product, as well as to improve its durability.
Spray Coating
Spray coating is a process where a coating is applied evenly to the surface of a plastic product to protect it from scratches, abrasions, and UV damage. Common types of coatings used in plastic fabrication include clear coat, UV coating, and powder coating. The coating process requires a clean and dry surface, and the choice of coating depends on the level of protection needed, environmental conditions, and heat exposure.
Wrapping
Plastic wrapping is commonly made from PVC (Polyvinylidene Chloride), although LDPE (Low-Density Polyethylene) has gained popularity due to safety concerns. Plastic wrap is produced by melting plastic granules and forcing the liquid through a die to create a tube of stretchable plastic. Compressed air is blown into the tube to form a bubble, which is then collapsed between metal rollers to create a thin plastic film. This film is rolled onto a large metal roll and later unwound, cut, and rerolled onto smaller rolls for consumer use.
Industrial Digital Printing
Industrial digital printing, specifically UV printing, is used to add high-quality photos, text, and graphics to plastic products. UV printers utilize CMYK, White, and Clear Varnish inks to achieve the desired output. This method is commonly used for promotional items, awards, and plastic signs.
Drying
Drying is a critical step in plastic fabrication to prevent cosmetic defects and maintain optimal surface appearance. Moisture content must be carefully controlled to avoid issues such as "splay" or "silver streaking", which occur when there is too much moisture during the molding process. Resin dryers are commonly used to remove moisture, and elevated temperatures facilitate faster drying, although they must remain below the softening or melting point of the material.
Curing
Curing is the process of applying heat to coated plastic products to protect their surfaces. Infrared heaters are commonly used to provide precise amounts of heat to specific areas of the product. The coated product must be heated according to the cure schedule provided by the coating manufacturer to ensure finish quality.
