Another example could be having one version of a part with a logo molded into it, while another version is smooth/unbranded. Using interchangeable mold inserts [...]


EMI Shielding for Plastic Parts

Copper Paint Coating for EMI Shielding If you need electromagnetic interference (EMI) shielding for plastic parts that house electronics, copper paint coating can be a good option. Copper conductive paint is widely used in higher frequency EMI shielding applications (>30 MHz). While other conductive paints like silver or nickel may be more appropriate for some applications,  copper is a common, low-cost EMI paint. There are some considerations you should be aware of when designing plastic components that will require EMI shielding. For [...]
