What is Overmoulding?
Overmoulding is a process that uses low-pressure thermoplastic to encapsulate and seal electronic components or cable assemblies. It protects against moisture, vibration and mechanical strain, helping you create more reliable, compact and durable products for demanding applications.

In the push for smaller, tougher and more reliable electronic devices, one manufacturing technique is gaining quiet but widespread traction: Low Pressure Overmoulding (LPM). Unlike traditional injection moulding, LPM uses gentle processing conditions that make it ideal for encapsulating sensitive components, all while cutting costs and accelerating development. What Makes Low Pressure Moulding Different? [...]
Every so often, a project comes along that reminds us why expertise and material choice matter so much—especially in the medical sector, where reliability is everything. In medical manufacturing, small components can cause big problems if they don’t perform under pressure. Recently, we were working with a medical device company based in mainland Europe on [...]
Overmoulding is a manufacturing process in which electronic components are encapsulated using a hotmelt material, for example Polyamides and Polyolefins. The low-pressure moulding process provides reliable protection from moisture, dust, and dirt as well as protecting against impact and vibration. A range of materials can be used to create durable, multi-functional products with improved protection, [...]
