Injection Molding
New Runner-Design Concept Boosts Quality & Productivity
Why 'naturally balanced' multi-cavity molds sometimes refuse to fill evenly is a mystery that eluded solution—until now. A simple concept called the MeltFlipper allows molders to increase cavitation and maximize output of quality parts.

A year after installing an unusual new process-cooling system, Venture Packaging molds 10% more containers on 25% fewer presses with 46% fewer workers and 50% less scrap.
Read MoreSequential Gating & Gas Assist Team Up for the First Time
Two fast-growing injection molding techniques—valve-gate sequencing and gas-assist technology—have come together in one application for what is said to be the first time. The part that united the two technologies was a 14 x 30 in. x 120-130 mil computer panel being converted to plastic from metal by Hewlett-Packard Co. in Roseville, Calif. It posed a number of process problems that were best solved by combining the two procedures.

You can now can leapfrog the previous obstacles of cost, complexity, and a long learning curve.
Read MoreKeep Machines Running in Top Form With New Software ‘Wizards'
Help has arrived for overworked plant managers, process technicians, and maintenance personnel. It comes in the form of three new Windows-based "Smart Manufacturing" software modules from Hunkar Laboratories, Inc. in Cincinnati. Hunkar's Smart Manufacturing philosophy is based on the principle of pre-emptive problem solving, which translates into "Fix it before it's broke."
Read MoreRapid Tooling Is Ready For Prime Time
Despite the advantage of speedy mold building, rapid-tooling technologies have gained only a toehold in the general moldmaking arena. But that could change as new developments improve dimensional accuracy, durability, and cooling efficiency to compete with traditional methods for making production tools.
Read MoreWhat is Higher Productivity Really Worth?
The math is simple and compelling. A productivity increase of only 20% can double or even triple your profitability. Here's a look at how it works and how to get your company to make the effort.
