Bespoke Enclosure Manufacturing

__________

Penta Precision machines custom enclosures for specialised applications for our customers all over the UK.

We manufacture both from raw material as well as modifying off the shelf moulded or specialist pre-moulded enclosures.

Combining our tool making heritage and production machining expertise, we are also able to offer machining design advice, helping you take cost out of manufacture.

We can machine up to 20kg weight enclosures within our milling capacity range of 475 x 550 x 1000mm. If your requirement is outside our limits, give us a call and we will try and point you to someone who can help.

Machined Enclosure Industry Examples

__________

We have experience in machining bespoke and custom enclosures for specialised applications in the following industries:

Custom Machined Enclosure Materials

__________

We can manufacture enclosures in a variety of materials, primarily:

Notes for Designers

__________

To aid machining, reduce processing time and thus cost, consider these factors in custom and bespoke enclosure design:

  • Specify the largest internal corner radii as possible

  • Keep wall cross sections thicker and more stable

  • Keep tolerances as open as possible

  • Where not critical, specify rougher internal surface machined finishes

  • Minimise the number of faces with features that require machining to reduce set-up time

  • Deep enclosures increase cutting tool length, reducing tool stability and slows processing time. Consider moving away from an “enclosure and lid” design to have a split line 50% down the depth of the enclosure, changing to a top and bottom half style assembly.

For more detailed information on designing enclosures, read our blog 'Electronic Enclosure Design for Machining'

If you're still weighing your options and want to see how CNC machining compares to other manufacturing methods for enclosures, see our article 'Which manufacturing method is best for enclosures?'

When your design is proven, we can help with final manufacturing machining and finish design so the specification is clear and can be manufactured repeatedly to the correct quality specification.

Machined Enclosure Materials and Applications

__________

Factors to consider that affect the choice of enclosure material are:

  • Indoor or exterior environment

  • Mechanical loading

  • Risk of collision

  • Gas, chemical or dust contaminants

  • Marine and salt water exposure

  • WEEE Directive and regulations on waste management and recycling 

 

Stainless Steel

Used where cleanliness and corrosion resistance is important due to cleaning regimes or harsh environmental factors. 304 (1.4301 and 1.4307) stainless is often specified for indoor clean room environments. Enclosures can tarnish and pit in environments open to the elements, salt water and where aggressive cleaning is performed. In such situations 316 stainless is a better choice. It takes 2 to 2.5 times the machining time to process stainless steel compared to aluminium, therefore making stainless steel an expensive and rare choice of material for bespoke machined enclosures for mechanically demanding applications.

 

Aluminum

Where the enclosure needs to be more robust to cope with bumps and knocks then aluminium is worth considering. Aluminium is a common choice of material for bespoke and custom machined enclosures. Aluminium is often considered to tackle the issue of “noisy electronics and assist with EMC protection. Applications where corrosion resistance is an issue, aluminium should also be considered. Where applications have high mechanical demands stainless steel is naturally the more robust option. However designers do consider and choose to manufacture in aluminium with uprated wall thicknesses to meet the mechanical requirements being dictated.

Where volumes are higher, firstly consider off the shelf standard die cast
