Bespoke Protective Cases.

Custom cases designed and built in house to your exact requirements

Sometimes it is impossible to find an “off the shelf” case that is the correct size for a specific product or application. Maybe the cases of the right size do not have suitable handles or do not feature wheels for ease of transportation. As case manufacturers, we can design and manufacture a custom case solution for you.

With an almost limitless number of configurable options, both custom flight cases and the brand new EXOCase can provide a bespoke case that is exactly as you require. When manufactured in tandem with custom foam inserts, you can also rest assured of a perfect fit between case and foam, and calculated levels of cushioning protection if required.

02: Benefits of a Bespoke Case.

How bespoke case manufacture can give your business an advantage

Looking for top quality case manufacturers? Then you have come to the right place! GWP Protective design and manufacture a range of flight cases and presentation cases at a well equipped production facility in Salisbury.

This ensures you can be confident that the cases and foam inserts you receive are of the highest quality.

With both design and manufacturing teams working hand in hand, we have supplied flight cases across the whole of the UK and beyond, and are certain that you will be impressed with the quality and performance of any case we manufacture for you.

Advantages of specifying a custom built case

  • Wide selection of custom case options available
  • Custom flight cases, EXOCase, N Case and Smart Case
  • Over 20 years as flight case manufacturers
  • Use of latest software to guarantee product protection

03: Custom Case Manufacture.

How are bespoke cases manufactured?

With a highly skilled and experienced team of designers and workshop staff, your cases can be manufactured to practically any specification.

By firstly creating a template within the latest design software, it is possible to fine tune this before passing the perfect, finalised specification to an experienced production team. This approach also means that a copy of the drawings for every flight case, foam insert and additional products is kept on file – ensuring should you ever need to re-order, you can get an exact replica within a very short lead time.

The cases that that GWP Protective manufacture in house – typically known as flight cases – are created from plywood panels (with phenolic, plastic or even aluminium layers) which are secured together with aluminium extrusion profiles and rivets.

Usually a range of hardware fittings would also be added, generally made from galvanised steel, which can include handles, locks, catches and even castors.

Foam insert manufacture
Custom foam insert being added to a case - by sourcing case and foam together the fit and compatibility will be much better.

GWP Protective are one of the few UK companies to produce the N Case and Smart Case range of presentation cases. However, if you have a specific requirement GWP can source a huge range of fixtures and fittings to match your exact needs – something non independent case suppliers simply cannot do.

Once the case is complete it is possible to further customise it through precisely engineered foam inserts that offer the optimum level of protection.

For more information on choosing foam foam inserts, or flight cases themselves, please use the links at the bottom of the page.

04: Case Components.

Components used for manufacturing cases

Below are details of the standard components that tend to used during the process of protective case manufacture. However, please note that this list is not exhaustive and if you cannot see what you require then please contact our team to discuss your specific needs.


Pre laminated or treated Plywood is used for the case panels as it is light, durable, and resistant to scratching and moisture. Beware of companies selling cheap alternatives created from MDF however, which will fail very quickly. GWP can source different panels material for additional strength if required.


Closing, locking or mating extrusions. These are used between the case and the lid to ensure a solid and secure closure, and are supplied as male / female. There are also special fittings for shallow lid and top hat constructions.

L or single angle extrusions are used as edge liners, running along the inside edge (meaning panels can be riveted to the fixture).

Custom case components
There are a large number of components that make up a custom case, giving you even more control over the performance and appearance of the finished design


Butterfly latches, usually recessed, are obviously used to keep the flight case securely closed.


Ball corners provide both a closure where the edges meet, as well as edge protection if cases are dropped. They also eradicate sharp edges on the corners, so as not to damage each other if used together in transit.


Hinges, again fairly self-explanatory, are used for the opening and closing mechanism.


Handles come in a range of shapes and sizes, although are commonly sprung and recessed. Most are now ergonomically designed so as to provide comfortable movement.

Wheels / Castors

Castors are often used on larger cases for ease of transportation, although we are happy to apply to these to any case if required.

05: Custom Cases With Foam.

Enhance any case with foam inserts

Besides the manufacture of custom cases, every case supplied (stock or bespoke) can be enhanced through the inclusion of completely custom foam inserts.

Foam conversion
Adding custom foam inserts, such as those manufactured from Plastazote®, adds a high degree of additional protection for your items

Designed and engineered by a dedicated and experienced team to ensure your items have the optimum level of protection (and the foam fits the case perfectly), your custom case inserts can even be produced with exactly calculated levels of cushioning performance.
