Electronics Enclosure Materials

Enclosure materials play a crutial role in the manufactoring process, demanding careful selection and expertise in industrial design, management and marketing. We help our clients select the right material for their electronics enclosures, whether it's for prototypes or mass-produced designs.

We know how to combine various materials, including wood, ceramics, composites and additive materials, virtually all plastics, glass, and metals. Our experience in prototyping and production of electronics helps us choose the best material options based on design needs, client preferences and budget.

We develop custom plastic cases for electronics using various types of plastics: ABS, ABS+PC, EK, PC, PE, PVC, PMMA, polyamide plastics, etc.
To create stylish electronic devices, we provide various wood species, including composite combinations, such as plastic enclosures for electronics with wooden inserts.
We produce metal electrical enclosure parts from stainless steel, aluminum, aluminum-magnesium alloys, using various technologies (stamping, moulding, milling, extrusion moulding). Our team can also create sheet metal case designs to meet your specific requirements.
Materials on request
We employ other variants that can be used in industrial processes, such as rubber, ceramics, glass, and more, at the request of the customer.

Materials for prototypes

At the prototyping stage it is not always possible to use materials that have been chosen for mass production. For example, prototyping of plastic electrical enclosures cannot be done with certain types of plastics which are nevertheless successfully used in manufacturing commercial devices. In this case, we use an analog which will reflect the characteristics of your original choice as fully as possible.

Material combinations

Combinations of different materials are often used in enclosure manufacturing. For example, when designing a plastic enclosure box for electronics, several materials may be employed at once: plastic + metal/glass/ceramics/rubber, etc.

In this case, we can provide relevant expert advice on manufacturing, which helps correctly implement jointing locations for selected materials to provide the specified requirements for integrity, flexibility and durability of the finished product, thus matching the designer’s and the customer’s preferences with real production capacities.


Choice of enclosure colour according to RAL and Pantone

We work with international colour management systems — RAL and Pantone — to ensure that the appearance of your case and mass-produced devices is clearly defined and reproduced.


Even if you are located on one continent and your production site on another, standardised colour-matching systems allow everyone involved in the project to see the final look of your device. You only need to find the right code on RAL or Pantone fans or colour charts.

Colour selection and coordination

Together with our clients, we determine the optimum colours, surface textures and degree of gloss when creating photorealistic 3D models of their new devices and reflect this information in the design documentation for production.

What we consider when choosing colours

  • Application area of your device
  • End user needs
  • How often the device will be touched
  • Internal components (if the enclosure is transparent)
  • Environmental factors

With RAL or Pantone pallets, it is possible to optimise production costs: similar shades may contain varying amounts of pigments, so if a change is allowed in the project, we can choose a more cost-effective one without losing quality.

Case studies on design and production with various colours and materials

Fish finder: industrial & mechanical design

Industrial design and construction of the new generation echo sounders.

  1. For the upper part, the “glass” is poured separately and silkscreened. This glass is used as a mortar piece, which is poured over the plastic.
  2. The resulting plastic part with glass is poured in rubber (TPU), which also forms the elastic buttons, serves as a protective bumper, and is a “gasket” to ensure the tightness of the case when assembled with the bottom part, which is produced in the same way, but without mortgaging parts.

To implement this idea, the optimal serial technology was chosen – a two-component (2k) casting, which uses a special machine with two installed moulds.


Qoobi One, a wireless vacuum tube preamp

To develop the mechanical design of a wireless tube amplifier, Qoobi One, using a ready-made design of our customer.

Non-standard materials were chosen for the production of the case:

  1. Anodized aluminum with manual polishing for an internal enclosure that cools radio tubes, hiding the device's printed circuit board with a digital-to-analog converter and a chip with Bluetooth 5.0 support.
  2. Thin quartz glass with engraving for manufacturing of the outer transparent case of the Qoobi One. It looks impressive and reveals the glowing radio tubes.

LED lighting of the device is controlled by a mobile application.


Analysis and consulting

Our projects also involve relevant calculations, computer analysis and simulation of manufacturing processes, which helps optimise enclosure designs, based on the characteristics of the material when it is cast into the mould.
