Proprietary Injection Molding

With millions of parts in inventory, we warehouse “job lot” quantities of some of the most common plastic closures used in the packaging industry. Our ability to maintain these ready to ship orders gives our customers peace of mind that their upstream supply line is secure and less threatened by constraints of JIT (just in time) inventory, purchase projection errors as well as unforeseen supply chain breakdowns. There are several testimonials in our company history in which our stock inventory saved.
