Rotationally Moulded Plastic Cases / Containers
Extra tough rotomolded cases from Peli Hardigg & SKB
Roto Mold cases (also referred to as “rotomolded” and “rotationally moulded” cases) are the toughest and most durable protective cases available today.
So, if you need to transport particularly large or heavy items, or simply require the highest levels of protection during transit, rotomolded cases are the perfect option.
Peli Hardigg™ Roto Molded Cases
Toughest waterproof equipment / transit cases
Widely used throughout the military on many “mission critical” operations, Peli Hardigg rotomolded cases (including both the ISP2 and Single Lid ranges) offer more than 300 different size options and allow for a high degree of customisation. This includes castors, wheels, purge valves, catches, custom designed foam inserts and even specialist configurations (e.g. Mobile Military)
Please see below for the range of Hardigg cases you can source and customise through GWP (official Hardigg distributors).

Exceptional performance for “mission critical” applications
Put simply, rotationally moulded cases are the toughest, most durable and long-lasting waterproof transit / equipment cases currently available.
In fact, due to the reliability of rotomolded cases from both Hardigg and SKB, they are often seen as a key component in many “mission critical” operations. This refers to scenarios where equipment failure is simply not an option – thereby preventing a snowball effect of a single breakdown leading to potentially catastrophic failures further down the line.
As such, rotationally moulded plastic cases are commonly used for military / defence, marine, security, aerospace, oil and gas, satellite, and telecommunication applications,
The rotational moulding process – using a high quality polyethylene polymer – creates a finished plastic case which provides impact resistance, is watertight, airtight, dustproof and corrosion-proof.
Using this method of manufacture (instead of injection moulding seen on Peli cases for example) also creates a case with thicker material at the edges / corners whilst being thinner on the walls. This not only adds strength but helps keep weight down too.
Custom Rota Mould Case Options
There is a wide number of ways in which you can customise your roto mold cases.
Firstly, there are various standard options available (from both SKB and Hardigg™ themselves).
This includes being able to add feet, specific handles and catches, tethering points, pressure relief valves and different hinges too.
It is also possible to specify bespoke case colours (if ordering a high enough volume), plus you can specify semi bespoke sizes by using a “cut and shut” method during manufacture. This also allows you to alter the lid / base ratio if required.
There are also a number of customisation options that GWP Protective can specifically offer.
This includes custom foam inserts, which are tailored to your products exactly. These foam inserts can also be different colours, have logos and instructions laser etched directly onto the material, and can even be manufactured to provide specific levels of cushioning during transit (usually determined by the products being protected).
It is also possible to add exterior branding using screen printing, or by adding labels / vinyl graphics too.
Roto Molded Case FAQs
Common questions regarding rotomolded cases
With a staggering array of models, sizes, and colours to select from, choosing a roto mold case can be difficult. It also makes it highly likely you will have numerous questions regarding these options.
A number of these most frequently asked questions are covered below but, if you cannot see the info you need, please contact a member of the GWP team for further assistance.
What is rotational moulding?
Rotational moulding was originally developed in the 19th century but has grown steadily in popularity since around the 1940s. The process uses a heated mould that melts the plastic material (for roto molded cases this is typically Polyethylene). The mould is then rotated in order that the plastic forms to the inside of the metal mould.
How are these different from injection moulded cases?
Injection moulded cases see pre melted material injected into a mould, filling the cavity to create the required shape. However, as rotational moulding uses a heated mould (and has to be cooled before the case can be removed) it is typically a more time-consuming process. However, rotational moulding does have a number of advantages, including it being easier to manufacture larger case sizes.
Are rotationally moulded cases really the toughest cases available?
The inherent way in which rotational moulding works helps to make cases manufactured using this method considerably tougher than the majority of injection moulded equivalents. This is because the moulding process will naturally produce thicker corners and edges (adding strength) and thinner walls (keeping weight down). Corners and edges can be as much as 15 to 20% thicker when produced in this way.
Who manufactures roto moulded cases?
Can foam inserts be added to roto mold cases?
Any rotomolded case can be enhanced further with custom foam inserts. These are not only tailored to the chosen case, but also feature recesses that are a perfect fit for your specific tools, products, or equipment. This in turn provides the highest levels of protection, whilst also improving usability / organisation too.
Have roto mould cases undergone any testing?
The majority of the roto mold cases offered by Hardigg and SKB have been extensively tested. This includes 810F and 810G Mil-Spec certification, IP68 rating, and compliance with the ATA 300 (now A4A) category 1 specification.
