Molded Parts

Written by: GOBA Editorial Team·March 1, 2026·5 min read

Molded parts are custom-manufactured components made from materials such as plastics, metals or elastomers. They are produced using different manufacturing processes to meet specific technical requirements that standard parts cannot cover.

What are molded parts?

Molded parts are individually manufactured components whose shape, material and properties are precisely matched to the respective application. They are used wherever standard solutions reach their limits and tailor-made components are required.

Which materials are used for the production of molded parts?

Material groups

  • Plastics: thermoplastics (PE, PP, PA) and high-performance plastics (PI, PTFE) for different requirement profiles.
  • Metals: aluminium, steel and brass for mechanically stressed components.
  • Elastomers: silicone and thermoplastic elastomers for flexible applications.

Essential material properties

  • High strength and wear resistance
  • Thermal stability across wide temperature ranges
  • Chemical resistance to oils, solvents, acids and alkalis
  • Electrically insulating properties

How does the production process for individual molded parts work?

The 7-stage manufacturing process

  1. Requirements analysis
  2. Design development (CAD software)
  3. Material selection
  4. Tool manufacturing
  5. Production (injection molding, extrusion, pressing, CNC machining)
  6. Post-processing
  7. Quality control

Modern manufacturing technologies

  • 3D printing: for prototypes and small series
  • CNC machining: for the highest precision
  • Automated production lines: for large series

Which fields of application exist for molded parts?

  • Automotive: engine components, seals, insulation
  • Electrical engineering: insulation parts, housings
  • Aerospace: heat-resistant components
  • Medical technology: precision components for medical devices
  • Construction: structural elements and seals

What are the benefits of custom-made molded parts over standard solutions?

  • Perfect fit: exact integration into existing systems
  • Improved performance: optimised properties for the application
  • Cost efficiency: reduced material consumption and less scrap
  • Longer service life: material-appropriate design for higher durability
  • Lower maintenance costs: less wear and failure

How do I find the right manufacturer for custom molded parts?
