Usually when a customer is looking for a Mechanical Engineer they are looking for a Mechanical Engineer who has experience with injection molded plastics to design some sort of an enclosure or test fixture. This person will have experience on electronic packaging of volume production devices, having designed with a variety of connectors, injection molded parts, etc.
Enclosures can range from something very minuscule to something very large and typically they are housing electronic components. Examples would be a cell phone housing very small components or a larger molded fixture such as a box which holds a desk top computer. Enclosures are made for all types of applications from commercial and medical to aerospace and defense.
In addition to designing the enclosure the engineer may also need to know how the air moves around inside the fixture and between the parts (air vacuum), etc., and sometimes how much stress the enclosure can withstand thus also designing it to be structurally sound. Structurally sound enclosures are necessary for all applications but especially in certain types of military or airplane devices.
Often times a Mechanical Engineer who has injection molded parts experience has sheet metal experience. They also utilize a variety of CAD applications for the design such as ProEngineer, Solidworks or AutoCAD.
It is important to find out what type of fixture the Injection Molded Engineer will be designing, the dimensions of the design and the design software used if you want to find an exact fit for you customer if you are a Technical Recruiter.
