Plastic machining is a process that involves the shaping, cutting, drilling, and finishing of plastic materials to create specific parts or products. Over time, this process has undergone significant changes, driven by advancements in technology, materials science, and manufacturing practices.
In this article, we’ll explore how plastic machining has evolved over time, from the early days of hand-crafting to the use of computer-controlled machines and 3D printing for custom plastic fabrication. If you’re in need of a quality plastic machining company, simply get in touch with the friendly team at Johndec Engineering Plastics WA.
Early days of plastic machining
The use of plastics in manufacturing began in the early 20th century, with the advent of materials such as Bakelite, the first synthetic plastic. At that time, plastic machining was a relatively simple process that involved using hand tools to shape and cut plastic parts. Machinists used a variety of cutting tools, such as knives, saws, and chisels, to remove material and create the desired shapes.
In the 1930s, the introduction of thermoplastics, such as polystyrene and polyvinyl chloride (PVC), further expanded the use of plastics in manufacturing. However, plastic machining remained a manual process, with workers using hand tools and manual lathes to shape and cut plastic parts.
Advancements in plastics and machining technology
In the 1950s, the development of high-performance plastics, such as nylon and acrylic, marked a turning point in the plastics industry. These materials were stronger, more durable, and more heat-resistant than earlier plastics, making them ideal for use in a wide range of applications.
At the same time, advancements in machining technology were making it possible to produce more complex plastic parts with greater precision. Computer numerical control (CNC) machines were introduced, allowing machinists to program the machines to perform a wide range of cutting and shaping operations automatically. This allowed for faster, more accurate production of plastic parts, with greater consistency and reliability.
In the 1970s and 1980s, new materials such as polycarbonate and acetal were introduced, further expanding the range of plastics available for machining. These materials offered improved strength, durability, and resistance to heat and chemicals, making them ideal for use in demanding applications such as aerospace, automotive, and medical devices.

3D printing and the future of plastic machining
In recent years, 3D printing has emerged as a powerful new tool for creating plastic parts. 3D printing, also known as additive manufacturing, involves building up parts layer by layer using a variety of materials, including plastics. This process is particularly useful for creating complex shapes and geometries that would be difficult or impossible to achieve with traditional machining methods.
While 3D printing is not a direct replacement for traditional machining methods, it is increasingly being used in conjunction with these methods to produce plastic parts more efficiently and effectively. For example, 3D printing can be used to create a prototype of a plastic part, which can then be machined to create a finished product. This allows for faster and more efficient product development, as well as greater flexibility in design and manufacturing.
Another emerging technology that is likely to have a significant impact on plastic machining is the use of artificial intelligence and machine learning. These technologies are being used to develop new algorithms and software tools that can analyse and optimise machining processes, allowing for greater efficiency, accuracy, and quality control.
What is plastic machining used for?
