Testimonials

Innovation Company
" From start to finish of my project PROTO MFG were great, they token a keen interest in my project and taking it to account all specification and profmance requirements. The end product was exactly as designed and performing as intended. Fast turn around . I will definitely use PROTO MFG again in my future and on going projects and recommend them."
Manufacturing Company
" Very pleased with the work PROTO MFG have done. Using metal instead of plastic reduces wobble on my train axles and makes further adjustment possible as they won't snap. Accurate sizing on small delicate parts."
Assembly Company
" Excellent work. Bid a fair price within a day of the job being posted and a very quick turnaround. Received the part less than a week after first RFQ. Highly recommend PROTO MFG and will definitely use again. Thanks again."
