→ Industrial design
Using the internal components and base as a reference, and working with one of our industrial design partners, an enclosure shape was developed that met our client’s aesthetic, ergonomic, and mechanical requirements.

→ 3d engineering
There are many elements that go into the proper development of the 3D database. The industrial design intent must be maintained. There needs to be sufficient room and clearance for all internal components. Mounting geometry should be sufficiently strong and also moldable. Wall thickness must be correct. Proper draft must be included, as tool-paths for the CNC machine will be generated with this data. |

→ 2d drawings
CNG Solutions knows that proper detailed documentation of the 3D database is as important as the 3D design. Critical dimensions, gate location, texture, material, and other details were specified that affect the cost and execution of the parts. |

→ choosing a factory
Many factors need to be considered when choosing a factory. Do they have experience making parts similar to the proposed design? On reviewing the mechanical design, do they have a good plan as how to handle all manufacturing considerations? Are there any capacity issues? Can they meet timing requirements? And always, can they meet cost requirements? Establishing a relationship with several factories is important, as every factory has its own strengths and weaknesses. |

→ mold drawing
Not only does the mold drawing show how the mold will be constructed, but it also allowed a final check to ensure all industrial and mechanical design constraints were being met. Gate type and location(s), knockout pin positions, side action and lifter parting lines are all just as important as water line locations, mold base size, and overall core and cavity layout. |

→ mold
Executing the construction of the mold after a proper mold drawing was fairly straight forward, but did require the continued attention of engineering when small details needed to be addressed. Mold materials should be appropriate to the expected life of the tool, as well as the plastic material being used. The mold was checked against the drawings throughout the tooling phase, before it was hung for the first time during the t1 phase (first shots off tooling). |

|
→ production parts
Each of the steps in this case study were all executed well. Once the molding parameters were established, It was very straightforward to get good production quality parts. Addressing possible issues throughout the entire process allowed for the successful molding of the enclosure. CNG understands the process! |
