Connections

Connectors are attached (soldered or welded) appropriate for the voltage/current combination of the unit.

Labels or tags are used for identification especially in the case of multiple outputs.

Preparation and Encapsulation

All COSHH requirements are fully adhered to with the provision of an extraction bay for various high fume materials e.g epoxy resins.

Many different type of batteries, sensors and electronic devices are suitable for encapsulation. This may be to prevent ingress of moisture, oils and other compounds/liquids or for achieving mechanical strength, safety requirements and possibly to provide protection against unauthorised copying.

We can accomodate different batteries such as: Ni-Mh, Li-Pol, Li-Ion, Ni-cad and many more! Also sensors, amplifiers - the list is very long!

For many purposes the encapsulant material is machine mixed and injected into or around the device. Specialist compounds are available to provide varying degrees of weigh - for example if used in weight critical applications, such as aerospace / satellite communications equipment where every gram matters as does outgassing characteristics!

We deal with batteries of varying sizes and of different accumulated voltages - packs of up to 100v or more, cells can be configured in any array to accomodate a custom location.

During curing, release of air can occur with cold curing.

To accelerate the removal of air within the encapsulant, either it can be placed in the oven and cured at an elevated temperature whilst having due regard to increased exotherm or placed in a vacuum enclosure.

Examples

Whatever your battery requirements, there exists an encapsulation process to manufacture it.

Ni-Mh, Li-Pol, Li-Fe, Ni-Cad to mention a few, at capacities up to 100amps plus!

We have considerable experience of military requirements!

Important Information

Just a small point - Ni-Cad batteries are now only authorised for use in special instances - e.g. medical instrumentation and military applications. Ni-Cad sales can be sourced by KDP but are subject to customer disclosure of usage and their end customer to comply with statutory regulations.
