An important chapter in our history began with the acquisition of our first injection molding machines in 1981 to produce closures for our glass vials. Over the years, we have expanded our network of molding platforms to include injection blow molding, extrusion blow molding, and injection stretch blow molding. With facilities distributed across the US and Puerto Rico, we are ready to serve your local needs for stock, made-to-order, and custom rigid packaging solutions.

Injection Molding

Representing the largest number of our presses, our injection molding machines shape thermoplastics, including engineering polymers, into a broad range of caps, tips, closures, plastic pipettes, oral syringes, and custom designs. Our presses range from 22 to 650 tons, housing molds containing up to 96 cavities. Our other capabilities include stack molding, multi-shot molding, insert molding, overmolding, and in-mold labeling. We follow scientific injection molding methods to develop and monitor our production processes.

Injection Blow Molding

The three steps of an injection blow molding machine transform commodity and specialty resins into strong and durable shapes, including round packers, Boston rounds, cylinder rounds, and custom designs for applications such as prescription and over-the-counter pharmaceutical packaging. Benefits of this processing method include high-precision-injected neck finishes and excellent dimensional stability from container to container.

Extrusion Blow Molding

The manufacture of our largest containers by volume relies on extrusion blow molding. We can produce round packers, canisters, Boston rounds, cylinder rounds, industrial containers, and custom designs in a variety of shapes and sizes, with neck finishes that are blown to reduce weight or compressed to improve dimensional accuracy. Because of their volume and neck size, powder and wipe canisters are made exclusively on extrusion blow molding machines.

Injection Stretch Blow Molding

The material properties of polyethylene terephthalate require the creation of a preform to stretch and orient the polymer before molding to achieve the desired shape, wall tolerance, and strength. The benefits of injection stretch blow molding include high-precision-injected neck finishes and excellent dimensional stability from container to container.

Our fleet of single-stage injection stretch blow molding machines create an array of clear and tinted round packers and cylinder rounds, as well as custom shapes such as square packers, specialty food and beverage containers, and heat-set containers for hot fill applications. We operate single-stage platforms rather than two-stage platforms, where preforms require reheating, to achieve blemish-free bottles, a thread start that can coincide with the bottle shape, and improved process efficiency.
