Plastic CNC Machining

CNC machining is applicable to a number of different materials, including various types of plastics. By using automated computer technology, CNC machines, or Computer Numerical Controlled machines, have the ability to shape plastics into precision products. Plastic CNC machining is one of the most popular services we provide at Schantz Machine and Fabrication. Let’s discuss this method of production in more depth and discover how you can benefit from services such as plastic CNC milling

How Does Plastic CNC Machining Work?

CNC machines work by using a special computer code to direct the movement of tools. This code, known as “G-code,” is much like a road map for the manufacturing process. Special software integrates the G-code into the CNC machine to control drills, lathes, and other tools. Once the CNC machining process is complete, the final product is revealed after material has been shaved away to create a precision product. 

 

Unlike 3D printing, which is an additive process, CNC machining plastic is a subtractive process. This means the initial material often comes in a block form and is bigger than the final product will be once completed. 

Plastic CNC Machining Materials

Many different types of plastics can be used for CNC machining. Each plastic type has its own unique qualities and advantages. Here are a few of the most common plastic materials we work with:

  • Acrylic: Lightweight plastic that is resistant to heat, weather, and impact. Acrylic is ideal for glass replacement and display applications.
  • ABS: Renowned for its strength and ease of machining. ABS is often used in housing and automotive applications.
  • Nylon: Nylon is one of the most widely used thermoplastics. Common applications include the food and beverage industry.
  • PETG: Formable and with a clear appearance, PETG is a great low-cost plastic choice. PETG applications include packaging materials and indoor signage.
  • UHMW: Also known as high-performance polyethylene, the UHMW family leads all thermoplastics in impact strength. It is a self-lubricating plastic that machines easily and is an ideal choice for many plastic CNC machining projects.

Benefits of CNC-Machined Plastic

When compared to traditional machining methods, plastic CNC machining holds many distinct benefits. Some of these benefits include:

 

  • Precision: CNC machines can complete complex projects, such as those with very tight tolerances, with more precision and accuracy than traditional machining.
  • Efficiency: CNC machines are able to operate for longer hours and with less fatigue than human operators. This can amount to more efficiency and shorter lead times.
  • Cost-effectiveness: CNC machines can save costs throughout the production process by minimizing material waste and labor costs.
