Choosing the right plastic material is a strategic step in the design of machined parts. Whether you are an engineering firm or a manufacturer, it is essential to select a polymer that is suited to your mechanical, thermal, chemical, and economic requirements.
At DSMP, specialists in the machining of technical plastics, we support our customers throughout the process: from material selection to mass production. Here is an overview of the most common materials we work with, along with their advantages and points to consider.
At DSMP, we work with high-performance polymers such as POM, PTFE, PA6/6, PEEK, PCTFE, PVDF, PEI, and PVC, each carefully selected according to the specific requirements of your project.
Each material has its own characteristics in terms of mechanical, thermal, and chemical resistance, as well as machinability.
Below, discover the main materials we machine at DSMP, along with their advantages and preferred areas of application.
POM - The economical and versatile plastic
POM (polyoxymethylene) is perfect for precision mechanical parts with moderate stress requirements. It combines performance and low cost, making it a go-to solution for many projects.
- Colors: Natural white or black
- Advantages: Excellent machinability, good rigidity, controlled cost
- Uses: Screws, spacers, gears, standard mechanical components
PTFE - The sealing and insulation expert
PTFE (polytetrafluoroethylene) is the ideal solution for aggressive environments or those requiring excellent electrical insulation. Its low rigidity requires a certain level of machining expertise, which DSMP has mastered perfectly.
- Colors: White or tinted on request
- Advantages: Excellent chemical resistance, very low friction, electrical insulation
- Uses: Seals, insulation for connectors, chemical and medical applications
PA6/6 - A classic to be handled with care
PA6/6 (polyamide) is an old material that is still widely used. However, care must be taken with regard to its behavior in the presence of moisture, which can cause swelling and alter the precision of parts over time.
- Colors: Ivory (natural) or black
- Advantages: Versatility, good mechanical properties
- Points to note: High moisture absorption → dimensional instability
- Uses: Seals, sealing seats, valves
PEEK - High performance for demanding environments
PEEK (polyetheretherketone) is a premium material. It offers exceptional performance but should be reserved for high-demand applications to ensure good value for money.
- Colors: Natural or filled (e.g., PEEK CA30)
- Advantages: High thermal resistance (up to 250°C), excellent stability, biocompatible
- Disadvantages: High cost
- Uses: Aeronautics, medical, space, critical precision parts
