Moisture can cause a wide range of issues in electronics and other devices, including corrosion of metal components and damage to sensitive electronic components. This is where the Low Pressure Overmoulding process comes to hand, as it can waterproof a wide range of electronic devices including circuit boards and connectors,

Combined Test Solutions is the leading UK provider of test equipment and instruments. We were asked to overmould two of their test products, the first being a Smart-Light, a tool for automated and quick test set up and fixturing of large harness tester interfaces.
Tim Morris of CTS explains the problems experienced before using the Low Pressure Overmoulding process provided by Overmould, how this proved to be the solution and why the chosen overmoulding material was used.
Haldex is a manufacturer of brake products, air suspension systems and products to enhance safety for heavy vehicles. Gabor Novek, Production Planner at Haldex, describes the issues and challenges involved in the recent development of a splitter cable used on the EB+ Gen 3 electronic braking system and how overmoulding proved to be the solution.
Osprey Measurement Systems manufacture precision monitoring equipment for the civil engineering industry. Their devices measure ground settlement and deformation during construction of road or rail embankments, tunnels, or deep excavations, ensuring an efficient construction process and safe infrastructure during its lifespan.
In such hostile environments one key challenge is to protect the electronics from water ingress. Overmould provided Osprey with a cost-effective overmoulding solution.
Mould sets for low pressure overmoulding are normally manufactured from aluminium and precision-machined to form the features of the desired part. Aluminium is well suited for mould-set manufacturing due to its excellent heat transfer properties (i.e. short cycle times) and is economical from a cost and time perspective.
Aluminium mould-sets are relatively soft and care must be taken not to damage the cavity surface. If the component to be over-moulded has steel or hard glass filled components, it is recommended to have steel inserts in the mould cavity to reduce any wear on key tool components. This is generally required when moulding connectors. Mould-sets can also be manufactured from tool steel such as P-20. It may be required to cross drill steel mould-sets to ensure sufficient cavity cooling.
Rapid Prototyping is a valuable step in product development. It provides a real-life product to analyse, test, and improve upon, before final production begins.
The goal in prototyping is to produce final production-like components.
The lessons learned in the prototype phase are then implemented when scaling up for volume production.
A strain relief is a standard feature in cables for relieving the stress and tensions between the rigid connector or device and the flexible cable. The point at which a cable exits a connector body or other component can be a critical failure point because of repeated flexing therefore a well-designed strain relief is vital for the mechanical and electrical integrity, optimum lifespan and general performance of all types of cables. By far the most superior strain relief in most applications, is a custom designed, overmoulded strain relief.

In electronics, encapsulation or potting is the process of pouring liquid resin over electrical and electronic components, circuit boards and completed electronic assemblies for electrical insulation and to protect the product against thermal shock, vibration, moisture and corrosive substances. Low Pressure Overmoulding is an injection process where the PCB assembly or electronic part is placed in a specially manufactured aluminium mould tool, and completely surrounded with a liquid compound that effectively forms the housing for the device. We compare the two processes.
