In the electronics industry, product performance depends not only on circuit design and electronic components, but also on the quality of supporting structural parts. Plastic components are widely used in electronic products because they are lightweight, insulating, corrosion-resistant, and suitable for complex designs. For many customized electronic devices, precision plastic machining has become an important manufacturing solution, especially during prototyping, small-batch production, and high-accuracy component development.

In the medical device industry, every component must meet strict requirements for precision, safety, stability and long-term reliability. From diagnostic instruments and surgical tools to wearable healthcare products and laboratory equipment, plastic parts are widely used because they are lightweight, corrosion-resistant, easy to shape and suitable for various functional designs.

Plastic components play an increasingly important role in modern manufacturing. From medical devices and electronic housings to automation equipment and consumer products, plastic parts are widely used because of their lightweight properties, corrosion resistance, and design flexibility. As product requirements become more demanding, manufacturers need production methods that can deliver both precision and reliability.

When choosing materials for CNC plastic machined parts, Delrin and Nylon are two of the most commonly used engineering plastics. Both materials offer good mechanical performance, wear resistance, and processing flexibility, making them suitable for industrial components, mechanical parts, fixtures, bushings, gears, and custom precision parts.

Choosing the right plastic material is one of the most important decisions in CNC plastic machining. A well-designed part can still fail if the material does not match the working environment, mechanical load, dimensional requirements or surface finish expectations.

When developing custom plastic parts, many engineers, product designers and purchasing managers often face one important question: should the part be produced by CNC plastic machining or injection molding?
