Overmoulding For The Medical Industry

Adding functionality to a product

Medical applications have long used polymers for the many advantages they have over metals. Overmoulding of components for medical devices enables improved aesthetics, added functionality, brand identification, and increased value. Applications include hospital equipment and devices, biotechnology, and fluid management.

Why Choose Overmould For Your Medical Device Project

A leader in Low Pressure Plastic Overmoulding

Overmoulding - Medical applications

Overmoulding Materials Suitable For Medical applications

Silicone

  • Excellent compression set – Silicone can rebound to original thickness when impacted with force and survive high temperatures.
  • The materials excellent properties make it highly practical for medical appliance applications, withstanding high impact forces, environmental challenges, and vibration damping.
  • Highly resistant to chemicals and to thermal degradation
  • When used as a sub layer or pre mould, recycling of electronics is easily achieved.

Polyamide

  • Polyamide is a synthetic polymer with excellent adhesive properties also providing a strong, rigid structure with good temperature and chemical resistance.
  • This material is perfect for Low Pressure Moulding, machining and and 3D printing so its invaluable in medical electronics applications.
  • Suitable for hand held and sensitive electronics protection required in the medical sector with useful application in the wearables arena.
