Automotive Recreational Vehicles Machining

The automotive industry has evolved over the years, and vehicles have advanced in terms of technology and automation. The number of automotive parts with complex designs and integrated circuits has increased as well, and this is estimated to go up in the future. This huge volume of automated parts can be achieved through automotive products machining. At the same time, it is crucial that all the parts are same and flawless, and this is where automotive OEMs can rely on CNC machining. Princeton Industrial offers precision machined parts for the automotive industry. We achieve this through our metal and plastics part machining capabilities combined with vast industry experience.

Automotive CNC Machining Capabilities

Princeton Industrial is one of the trusted names in the automotive industry for plastic machined parts. Our following automotive products machining capabilities along with excellent services have earned us plenty of satisfied clients in this segment.

Common Materials Used for Automotive Products Machining

At Princeton Industrial, we work with the following materials to create automotive CNC machined parts. We use both metal and plastic for our automotive CNC machined parts. Here are the metals we use

    • Aluminum: This robust, durable yet lightweight metal is widely used in the automotive sector. We use aluminum types and alloys based on each requirement and the level of strength and hardness required. We have our own cutting tools to cut this extremely hard metal.
    • Stainless steel: We use various types of stainless steel as it is machinable, robust, non-magnetic, and corrosion resistant. We use Swiss machining, turning, and automated multiple axes machines to make these parts. We have in-house tooling capabilities for the same.
    • Alloys: Various metals are combined to get the best output in terms of robustness, flexibility, and other physical and chemical properties required to make a part. An alloy enhances the properties of the original metal. We use aluminum as well as steel alloys.

Here are the plastic materials we use for automotive parts:

    • Delrin: This is often used in bushings and gears among other automotive components. We use CNC milling, turning, and Swiss machining for Delrin components. Delrin is a plastic from the acetal family and offers the required strength, dimensional stability, friction resistance, and endurance to the part.
    • Nylon: We use CNC turning and Swiss machining for Nylon, and this plastic helps achieve tight tolerances. It can withstand high temperatures and is friction resistant. It is commonly used to make bearings, bushings, and gears.
    • Teflon: Teflon or PTFE has a high endurance and impact strength. It is resistant to friction heat, radiation, chemicals, and so on. We often use Swiss machining and CNC turning machines for Teflon.
