WH Kemp provides potting and encapsulation services from a purpose-built facility on our Wiltshire site, protecting electrical components from moisture, dust, vibration, corrosion and electric shock, and improving the reliability and longevity of the finished unit. These capabilities were added to our sub-assembly offer following demand from our own wiring harness and cable assembly customers.
Our Potting and Encapsulation Capability
Potting and encapsulation are closely related processes. Potting involves pouring compound resin into a pot to cover the components enclosed inside. Encapsulation immerses the whole device in the compound, coating the exterior of the unit.
Potted components can act as a flame-path barrier between electrical parts and flammable chemicals. We have also built strong experience in encapsulating components housed within metal enclosures. We use epoxy resins, silicones and cementitious products, selecting materials for the requirements of the application.
Our Sector Experience
Our customers operate across demanding sectors including Defence and Uncrewed Systems, Nuclear, Grid and Energy Infrastructure, and Industrial, Fire and Safety.
Many of these businesses design machines and instruments for deployment in challenging environments and climates, and rely on us to understand what reliability means in practice. As requirements have become more demanding, we have continued to invest in and upgrade our capability.
Our Process and People
Our potting and encapsulation area is fully enclosed within our factory site, with local exhaust ventilation installed and elevated-temperature curing used to improve product properties and process efficiency. The facility is staffed by an experienced team, including a chemistry graduate who can advise on the appropriate resin and process for a specific application.
Inspection and Testing
We treat every assignment as unique and work to agreed timescales throughout. For larger projects, we can establish a dedicated process area with the customer to support the required process and finished-product quality.
All products undergo post-potting inspection and testing to each customer’s requirement, which can include pressure testing, electrical function checks and leak testing.
Our Performance Controls
All products are manufactured within a Quality Management System conforming to ISO 9001:2015. Samples of resin are taken from each batch, cured alongside the product, and subjected to destructive testing and inspection. Our technicians and team leaders remain approachable and responsive throughout every project.
