Custom Plastic Manufacturing Services

   Gulden has been manufacturing ophthalmic medical devices for over eighty years.  We’re still located in the USA and can proudly say that we make our products right here in Philadelphia.  If you have a project that involves some plastic work, even if it is not necessarily related to eye care, we may be able to help you achieve your goal.  Below you will find a list of our machining services as well as some pictures of our Elkins Park facility.  Fill out our Contact Form if you would like to discuss your project with us.  If needed, we are happy to sign any confidentiality agreement you may have.
