Insert Molded Plunger Assembly for the Valve Industry

(click on thumbnail to enlarge)

Advanced Molding Technologies custom built a series of plungers for one of our clients in the valve industry, utilizing our insert molding service. Using a two-dimensional, customer-supplied CAD drawing, we manufactured the plungers using top-quality polyester material. The products were constructed to meet exact sizing requirements, meeting a (+/-) .002 inch precision tolerance and a
(+/-) .2° angular tolerance.

The custom plungers contained two types of threading: an insert molded ACME 29° Special, Double Thread-RH Class 2G brass insert, and a molded 10-32 thread.
