The No Molds Required Technology

What is No Molds Required (NMR)?

The No Molds Required Technology is a very unique plastic fabrication method used to create custom plastic electronic enclosures, boxes, housings, panels, shrouds, trays and other plastic fabricated parts. It combines elements of woodworking (tongue and groove), sheet metal (forming/welding (solvent)), and of course, basic plastic fabrication. Combine all three industry techniques using additional unique process elements, and you end up with NMR Technology. Some would say we bridge a gap between sheet metal fabrication and plastic fabrication. Additional advantages of NMR are described throughout the site.

How Your Plastic Enclosure Project Flows Through Manufacturing

The process begins by taking in your hand sketches, CAD drawings, or solid models for quotation. For quotation purposes, PDF’s with overall dimensions are preferred. Once a quote is submitted and a purchase order is sent, we will begin CNC programming of your custom plastic enclosure.

The first step in the NMR plastic fabrication process is CNC Milling. We route out the plastic enclosure components in the flat. The holes, cutouts, and recesses are applied during the milling process.

After CNC routing, the parts are moved to the sawing stage. Here the parts are given a 45 deg. miter on the underside of the part. This serves as the bend location. Material is removed in this fashion to hold tighter tolerances during the bending process.

Before bending plastic enclosure components, the parts go through another operation at faceting. During this stage, the parts are deburred, chamfered, or radiused on the edges.

The bending process is also CNC controlled. A complex table made specifically for NMR Technology allows us to hold tight tolerance angles to complete the forming process of custom plastic housings.

Now the parts are ready for assembly in the bonding department. Here, component plastic parts are solvent welded together and bend joints are welded to give the part additional structural integrity.

Value added services are incorporated at different stages of manufacturing. Digital printing on plastic enclosure components is applied prior to forming, and painted plastic enclosures are sent out after bonding. In the case of EMI coating, it is applied to plastic enclosures before milling in most cases, but can be added after final assembly as well.

Lastly, the custom enclosures are packed and shipped per customer instruction along with all required paperwork.

"The Envision technology provides a welcome alternative to mold purchases during project development, and results in a significant competitive advantage in reduced costs and cycle times. The availability of this technology option will certainly continue to yield long-term benefits in development, and may provide viable future production solutions as well."
