What should you check before choosing a junction box manufacturer?

Enclosure Cover

Junction Box

The enclosure cover can be set to transparent so clearly monitor the status of the equipment inside. In thermoplastic enclosures, the whole cover is either grey or transparent. Grey covers are available both in ABS and polycarbonate. Transparent covers are available only in polycarbonate. VSM Plast terminal enclosures are also made of die-castaluminium. Modular enclosures come with a hinged window available either in smoke-grey or transparent.

Enclosure walls

Junction Box

The material thickness of our thermoplastic enclosures is greater than that of similar products in the market. This helps in the machining of threads. In addition, the usage of e.g. push buttons on the cover is safer since the material is more rigid. The bases of polycarbonate enclosures with knockouts have been manufactured using high-grade polycarbonate in order to add rigidity to the enclosure walls and to make it easier to knock out the cable entries. We have a modular tooling structure, enabling cost-efficient mould modifications. This is especially efficient when making customer-specific holes and cut-outs in a large series of enclosures.


Junction Box

We use injected, jointless PUR (polyurethane) gaskets in our thermoplastic and aluminium enclosures to ensure a high protection class. The standard gasket material of our aluminium and polyester enclosures is silicon.

The gasket that we use has the following temperature operating variations:

  • Polyurethane: -40-+80°C
  • Neoprene: -40-+100°C
  • Silicone: -50-+150°C
