Prototek Manufacturing Introducing Instaquote Online Quoting


, , ,

Contoocook, NH – November 12, 2013 – Prototek Global Manufacturing has seen a need for an online quoting system for budgetary purposes. We believe our customers should be allowed to quickly choose a few variables from a drop-down list on our website, and receive an instant, accurate quote, according to their part’s requirements. As the leaders in quick turn precision prototypes, that is exactly what we intend to bring you.

Our new proprietary online quoting program, InstaQuote®, will fill the void that companies have inaccurately assumed is inherent in the industry. There will be no more need to wait for a quotation, only to find you could change a design element or two and save on manufacturing time and cost. Upon visiting our InstaQuote® page for the first time, you will request an account, and an email will be sent back to you shortly with your login credentials. Once logged into your account, there will be a quick tutorial on how InstaQuote works, and then you will be able to process as many budgetary InstaQuote®s as you would like, as well as view previous quotations, place an order, or submit payment for a job.


Using InstaQuote® is fast and simple. Customers would select their material type and thickness from a drop-down, then how many cutouts, counter sinks, taps, and bends there are, along with a few other variables that may pertain to their job. You may also feel free to go back and change any of your options at any time. After being  satisfied with your InstaQuote®, clicking a Submit button would email both parties the end result as well as saving it to your online account.


Prototek’s niche has always been quick turn precision sheet metal and CNC machined parts. InstaQuote® is the only program of its kind, and we know this will become the industry standard for prototype budgetary analysis.

The Prototek team is very excited to bring to you exactly what you have been waiting for.
