West-Tek is primarily a sub-contractor to the High voltage industry, since our incorporation we have established the company as a turnkey solution for our clients and have the knowledge and expertise to provide a “conception to completion service”, from initial proposal through to completed product.
We specialise in low to medium volume production. We work closely with the client to ensure that the requirement is fully understood and delivered at each stage of the process to minimise error with a “right first time” approach.
Even the smallest air entrapment in a device working at 100s of kilovolts AC can create an area of electrical weakness which, over time, can lead to catastrophic failure in use.
We use high vacuum encapsulation using our own formulations and processing technology to ensure the best possible encapsulation.
Most moulding processes produce products with poor batch to batch reproducibility, and wide dimensional specifications to accommodate their intrinsic variability. Some of our high voltage components need to be assembled to an extremely close fit. Our process control ensures good batch to batch conformity, and enables us to work to dimensional tolerances of <250µm.
Our In-house Capacities Include:
- Mould design and manufacture
- Coil winding
- Component assembly
- Encapsulation resin formulation or specification
- Vacuum degassing of materials
- Casting (or potting) under vacuum
- Electrical testing
- Cast components up to 500mm across
- Auto dispensing systems for tight control of mix ratio and rapid production
- UV cure systems
