Barbed Hose Connector Expertise

Engineering resources at automotive OEMs have shifted away from “classic” part design and toward strategic priorities, such as electrification.  As a result, the burden of part design and design for manufacturability (DFM) is falling more and more to tier 1 and tier 2 suppliers.  It's critical to find an experienced ideation, design, development, and fulfillment partner that can take on these additional responsibilities.

At Echo Engineering and Ammex Plastics, we've made automotive barbed connectors one of our top focuses and part of our core technologies.  These are some of the most complex components of a vehicle to make when it comes to injection molding.  It's not just molding a part based off a print, it's understanding how glass-filled nylon flows, gate location, parting line review, and much more. Below we've listed just some of what goes into these projects when you work with us.


Critical Elements We'll Review With You

Engineering Design Review

Engineering design is one of the most critical aspects of your project.  Our engineers will review with you your design’s wall thicknesses, sharp transitions, knife edges, tolerances & technical specs, gate locations, and materials in order to ensure we are able to manufacture the connectors to what you need.

Tooling

Quality tool engineers can balance melt flow and reduce cycle times with hot runner systems, increase cooling capacity with copper cores and forced air flows, and produce precise round parts with out-of-round tools.

Depending on the part design, material flow, and residual stresses, sometimes it takes an out-of-round tool to produce precision round parts like fluid connectors.  Below are just a few examples of what needs to be factored in towards injection molding a barbed connector that will meet tight tolerances.
