Insert Moulding

Insert moulding is an important part of injection moulding as it gives medical device suppliers the opportunity to add specialised features to their products. The process allows for metal inserts, such as bushings, electromechanical parts, filtration materials and other parts to be inserted into a single component through the injection of thermoplastic around the parts (or inserts). This creates a highly robust, integrated assembly with the additional components offering new functionality to the user.

The advantages of insert moulding

A well as adding extra functionality, insert moulding can improve the strength, quality and durability of the end-product – vital when you create medical devices such as heart defibrillators.

Insert moulding has many other advantages when utilised by experts, such as introducing cost and time efficiencies into the production process.

  • Lower assembly costs – Integrating parts during the moulding process removes the need for the parts to be added in a standard production line.
  • Reduced size and weight – Because the inserted parts are integrated, there is no need for fasteners or connectors.
  • Increased reliability – With all parts firmly secured within the thermoplastic structure, there is less probability of loose parts or faults.
  • More flexibility – Perhaps the biggest benefit to be gained from insert moulding is flexibility. Developers can design in features at the pre-development stage.
