Injection blow and stretch blow moldmaker touts beginning-to-end engineering support

Big 3 Precision (Centralia, IL) announces full engineering support for customers that spans the start of the project to delivery of the ready-to-run mold, a service that it claims is rare among designers and manufacturers of injection blow and stretch blow molds.

When a converter or customer brings an idea for a new bottle design to the company, Big 3 typically begins with an evaluation: Is this a feasible design for the injection blow or injection stretch blow process? All projects begin with a kick-off meeting to verify technical details and customer expectations.

Big 3’s product development and validation lab then begins trial runs on a one-cavity prototype mold and forwards quality data from the trial run to the customer for evaluation prior to completion of the production mold. When the production mold has been built, the mold qualification process begins. The company has invested several million dollars over the past 10 years in state-of-the-art injection blow (IBM) and injection stretch blow (ISBM) molding machines. For the one-step ISBM process, Big 3 uses three Nissei machines, which include a 70DPH, 250HT and 50MB. A Sidel SBO-1 lab machine is available for the two-step ISBM process. 

To qualify IBMs, Big 3 has three 40-, 115- and 135-ton Jomar machines and three Uniloy machines, including a 54-3 ton co-injection machine and 88- and 199-3-ton machines. A Big 3 BMP 145 ton is also available for qualifying molds.

A set-up packet of the final process, a set of prints and other critical process information pertinent to the new mold is provided to the customer prior to receiving the mold.

“From beginning to end, Big 3 Precision is committed to assisting customers through the entire project until all their requirements are met,” said Alan Scheidt, President and CEO. “When the production mold is shipped to the customer, Big 3 process personnel can be on-site to ensure the mold runs as specified and produces bottles to spec. The goal of Big 3 Precision is to make it as easy as possible for our customers to not only get the best bottle design but also the optimum process for high productivity and efficiency,” said Scheidt.
