CapabilitiesVinyl Dip Molding

As one of the largest and most experienced vinyl dip molders in the world, our worldwide VDM operations service VisiPak customers with all of their needs for vinyl caps and closures. 

Vinyl Material Options

The breadth of our business and our extensive material compounding capabilities allow us to offer the largest selection of materials in the industry at extremely competitive prices. By mixing our own plastisol we avoid the mark-up that most molders pay to their compounder and we are able to recycle most of our plastisol - reducing our environmental footprint and elminating expensive disposal costs.

Over the years, we have developed over 500 formulas for the varying needs of our customers.  However, if none of our existing formulas work for your application, we can utilize our research and development lab to develop a new material.

Engineering and Prototypes

Our in-house engineering specialists around the world utilize their expertise in closure design to explore all possibilities in determining the best design and material for your packaging application. Our goal is to design your part in the most cost effective manner and to design it to deliver the highest level of performance required.

Not only do we have over 50 years of design experience, but we utilize some of the most sophisticated design and manufacturing software. We've grown with CAD CAM technology beginning in the early years of AutoCAD, then Pro-Engineer software. Collaborating with all our locations, we work seamlessly using PTC Creo and Siemens NX programs to seamlessly integrate the tooling fabrication process.

One of the primary benefits of dip molding is related to its inexpensive and accurate prototyping process. With a dedicated sample lab producing parts daily, we are able to provide prototypes for engineering and marketing tests at an insignificant cost.

The Process

The dip molding process is unique in its ability to manufacture caps and closures in extremely high volumes utilizing innovative machine designs that allow us to make many different sizes, shapes and styles of caps on closures.

Our Specialty

With over 50 years of experience, our custom dip molding capabilities are second to none. We have pioneered the market in regards to the double dip and triple dip process and invented numerous materials including Tuffoam®, Softex®, Vynaprene® and Polysuede®. As a fully integrated manufacturer, we strive to offer our customers the best value in the industry.

Benefits of Dip Molding

  • Low tooling costs...typically a fraction of injection molding
  • Quick and inexpensive prototypes
  • Short lead-times on custom tooling...weeks versus months
  • Innovative materials and textures
  • More vibrant colors can be achieved with vinyl
  • No internal stress molded into parts

Benefits of Dip Molded Caps and Plugs

  • Caps of varying lengths can be made with no tooling charge
  • Vinyl material stretches to fit odd shapes and easily conforms to beaded or flared tubes
  • Vinyl material will not crack or split like low density polyethylene
  • Vinyl material does not shred when capping or plugging threaded items
