What makes our Pro Classic Cases the best?

About Flight Cases….. Many flight cases look similar. Black or coloured plywood panels, chunky corners, butterfly latches, lots of pop rivets etc…. It’s only when you look underneath the skin, do you come to realise that most are mere facsimiles. Many cases on the market today masquerade as flight cases but are flimsy sub-standard products; that just disintegrate at the first moment of stress, shock, vibration, impact and DROP. So what makes our Pro Classic Cases different…and more importantly…the best?

We would like to tell you about the unique features of our Pro Case Classic & Pro Rack Classic that have made these cases the most sought after flight cases in the world. And why every discerning Pro Case Classic customer chooses them. From the legendary ’70s & 80’s touring rock bands to the Blue Chip FTSE’s and Fortune 500 companies around the world.


Our history in Flight Cases

In 1971 CP Cases was impassioned to design and build the very best flight cases in the world – bar none. The two original founders were themselves, experienced semi-pro musicians, who (in their day jobs) worked in the Pro Music industry; rubbing shoulders with the touring Pro Bands on a day to day basis. The insight that gave, as to what the market really wanted in a flight case was clearly obvious. Rugged, delivered on time every time, fit for purpose and a case maker who deeply understood the needs of the customer/application.

We researched every single component part, without compromise, to find the very best raw materials. The hardest wearing surfaces, the highest quality hardware and the strongest and most long-lasting riveting techniques. No quarter was spared in trialing and performance testing our products. We road-tested them, punished them with immense impact and drop testing. We shook them, drenched them, left them in high humidity climates; in the tropical heat and in the cold of the Arctic.

Many of our customers are still using Pro Cases Classic cases that they bought nearly 40 years ago. Where the cases still perform and protect as they did when new. We know for a fact that there are many “Million Mile” cases out there that show little sign of wear and tear. Also, showing no functionality loss and will continue to faithfully serve their owners for decades to come.

CP Pro Classic is, without doubt, the Rolls Royce of all flight cases. With a choice of materials and structural design, it is a well-proven manufacturing process with quality of build. That is why all CP Pro Case Classic and Pro Rack Classic products are “Guaranteed for Life”.

Let’s start with the very basic materials…


Pro Classic Plywood

We only ever use Finnish / Baltic birch combi WBP plywood. This sustainably sourced plywood consists of thin cross-laminated sheets of birch and spruce which are bonded together. Using phenolic resin adhesives – under huge pressure and heat cured. We’re often asked if we use “marine plywood” – let’s dispel this myth about marine ply (which is only called “marine” because it is bonded using the very same phenolic resins that we use on our Baltic plywood). The big difference is that Baltic birch is much MUCH tougher and harder than lightweight marine ply. Therefore offering a far superior “fix” for rivets.

For more info on WBP plywood see here.



Pro Classic External laminate

Exactly the bonding same process is used to laminate our unique vulcanised fibre (VF) external protective skin. This gives the individual panels strength and resistance to impact and abrasion that is second to none. The combination of WBP birch plywood bonded to VF is recognised by many extreme sports equipment manufacturers. It is the material of choice for performance skis and skateboards.


Vulcanised fibre (VF)

This sheet is a laminated plastic composed of only cellulose. The 0.50mm thick material is a tough, resilient, hornlike material that is lighter than aluminium; tougher than leather and stiffer than most thermoplastics. The newer wood-laminating grade of vulcanised fibre strengthens wood laminations used in skis, skateboards, support beams and is used as a sub-laminate under thin wood veneers. VF provides an unobtrusive uniform matt black surface finish. It is almost impossible to abrade or cut through, will not burr; even after years of extreme abuse and rough handling. It is lightweight (lighter than aluminium) and readily accepts decals, stencils and screen printing.


Chippendale like furniture construction

Each panel is accurately machined to size, before adopting cabinet making techniques to pin and glue them together into a 6 sided “cuboid”. The PVA adhesive is left to cure before we trepan off the lid. This gives us a 5 sided base and a 5 sided lid that are already rigid and strong; before any edging, rivets or hardware are even fitted. This construction method is one of the “unseen” elements that ensure structural longevity, resistance to impact and performance integrity.


Pro Classic Edging

From the outset, we were worried about the handling problems of using aluminium edging. Whilst aluminium is lightweight, it burr’s very easily when dragged across rough surfaces. Handling thereafter becomes so hazardous that thick (gardening) gloves have to be worn to prevent hands and skin being ripped and torn; ask any touring roadie because you’ll get the same answer. Another concern was that of weight – whilst aluminium is perceived as a lightweight alloy, it is significantly heavier than VF.

Therefore our material of choice, inevitably, was the same vulcanised fibre that provides abrasion and impact resistance to the case panels. We carried out extensive field trials of how VF would stand up to truly abusive treatment. Abrading along a narrow edge. Continual scuffing across the tailboards of trucks. Dragging over rough ground and up metal stairs. And finally, tumble tests and straight drop tests. The results were undeniably conclusive. VF was by far the better material for edging, but we opted to increase the material thickness threefold; to ensure a lifetime of faithful service. This meant we had to cut and form strips of 1.5mm thick VF into a 90-degree right-angled edging strip – easy!

Just get yourself a set of fully geared graduated forming rollers – going from flat to >90 degrees in small increments. Ensure that each graduated pair of mating rollers have a high tonnage applied to them equally. And then (if that’s not enough) make sure that they are individually heated (and I mean very hot!). This is to ensure a consistent result of repeatable VF heat forming that finally gives us Pro Classic edging strip.


Which rivets?

There are literally 1000’s of different types of rivets in use today – choosing the RIGHT rivet for the job is not as simple as it may seem on first sight. Considerations have to be given to what the rivet is expected to do (shear, tension, compression, torsional stresses). What material the rivet is made from. What materials the rivet is fixing together. How thick are the combined substrates. What profile the rivet head should have. What is the shank length and what is the shank diameter….the list goes on….

Most flight case makers opt for an aluminium pop rivet straight off the shelf. They want it to be readily available in small quantities, in many sizes, so there is no need for investment in special machinery to set them back. They do have however many shortcomings, the most important of which are, they have very poor shear strength (very much required when a loaded case is dropped). The heads wear away very quickly when repeatedly dragged over rough surfaces, and standard pop rivets allow water to pass straight through them.

We carried our much research into finding the most suitable rivet for flight case construction. A rivet that gives excellent shear strength, excellent pull out resistance, and one that will not wear away when continually abraded or dragged over rough surfaces. The only contender that passed all tests with flying colours is a machine-driven, self-piercing, nickel-plated steel rivet. Either semi-tubular or bifurcated (depending on the substrate/application).


Build Sequence

Build Sequence is when all of the individual component parts are mustered together on the specially designed pneumatic assembly benches for the build to begin. Every Pro Classic during manufacture is accompanied by an engineering drawing. This gives a fully detailed Bill of Materials (BoM), assembly instructions (often depicting detail graphics), internal foam or compartmental designs, and any special instructions that the customer/application has requested.

After travelling through the assembly process, the case is hand-fitted with internals such as foam, dividers, compartments, drawers, struts etc. Our Foam Engineering Dept is able to craft various types of foam (PE/PU/Nitrile etc) using CNC programmed routers. Band saws, slitting saws, oscillating blade cutting is also used. And sometimes we use hand sculpting to achieve the exact fit required.

The final port of call is the cleaning and inspection department. This is where a close and personal examination of the case is made. Checked against the drawing, detail cleaned and then finally sent to the despatch dept which wraps, packs, palletises. Whatever is required to get the case to the customer’s door in pristine condition.
