The degradation can be reduced by adding a UV stabiliser or a plastic paint to the finished housing. It is also possible to add a conductive surface coating to plastic housings, but this increases costs and increases production steps. Plastic housings can be manufactured either by injection molding, which is a cost-effective choice for mass production, CNC machining parts.
Sheet metal has lower material costs than CNC machining, and most of the raw material does not have to be removed. Sheet metal is robust, scalable and durable. Sheet metal parts can be fabricated from CAD models.
Injection molding is ideal for simple plastic housings that can be used to make housing products such as handheld controllers, sensors, electronics, keys, displays and more. This is a unique process for the production of plastics, which takes into account the design criteria to produce the most economical plastic housing. NMR Technology Molding requires a technology that includes a plastic design that is used to manufacture customized electronic plastic housings, tools and molds.
Rugged Enclosure Shop is the leading manufacturer of commercially available plastic electronic enclosures and electrical boxes for OEMs in a variety of industries. Envision is proud to offer many types of customized plastic enclosures that are suitable for many applications.
If you want to build a box like the one shown above, this tutorial will show you how to make smooth custom enclosures step by step. The construction of a plastic housing begins with a dimensioned drawing or CAD file showing how the printed circuit board and electronic components orient themselves in space. If the design requires intricate details, you might want to get a CNC milling machine and use 3D CAD software to create a solid model of the housing parts.
Bending the parts in a computer controlled thermal bending machine that resembles a sheet metal and has a brake press. The bends are cut on a tailor-made table (see "sheet metal extension") to increase bending accuracy.
Tolless technology is a CNC -machining and manufacturing process relying on assembly techniques from the sheet metal and wood carpentry industries. Unlike competitors who use prefabricated housings, we use this process from start to finish from scratch. It can be used to create custom plastic enclosures, hog-outs, enclosures with bezels, machined parts and assemblies that are faster to manufacture than our 10-step process.
Another advantage of our method of building plastic housings is the fact that customers can design flexibly at any stage of the product life. At Toolless we integrate modifications on the fly as well as individual parts for recurring production with a minimum of orders.
Electrical box enclosures are box cabinets used to protect sensitive elements in electronic devices from external elements. While some electronics are made of wood or acrylic - turntables and handheld gaming equipment, for example - the vast majority of consumer electronics enclaves are made of rigid plastic or metal. Metal housings tend to be more stable and durable than their plastic counterparts and can be made of aluminum, galvanized carbon or stainless steel.
