If you’re looking at buying a used injection molding machine, below are some things to know/ask before purchasing.
Plastic parts made using the Structural Foam process have a cellular or a structural core, surrounded with a thick outer layer (skin) that combine to give the products a greater strength to weight ratio and up to as much as twice the rigidity of the solid plastic products that are of the same material and weight.
As NPE 2018 draws ever closer, the majority of the plastics industry in the U.S., and even the world over, are putting the final touches on their marketing and tradeshow booths and assorted items as they prepare to print, package, crate, ship, tow, haul and ultimately descend on Orlando, Florida. For exhibitors, the tradeshow is undeniably their best opportunity to showcase their latest and greatest technology, products and applications to respond to the ever evolving demands and changes in the industry.
What is injection molding? Injection molding is a manufacturing process commonly used for fabricating items from plastic trinkets and toys to automotive body parts, cell phone cases, water bottles, and containers. Essentially many of the plastic parts that we use in every-day life are injection molded.
One of the many age-old debates that crisscross the plastic injection molding industry is that critical decision to either attempt to extend the life of an older machine or replace it. I would dare say that this is a topic far too familiar with plastics manufacturing in the United States, with an installed base of over 35,000 machines across the country with varying degrees of age, almost half of which are over 5 years old.
It cannot be overstated that the process of selecting the appropriate screw and barrel combination for your plastics application is a critical part of the success or failure of any particular machine cell. However, most people may not realize how often that this very selection process is done in error or even done incompletely.
The plastics industry is but one of many industrial and technological sectors of the US and global economies that are highly fixated on time. The cliché adage, time is money (and yes we’ve used that in an ad or two), is actually quite appropriate if not downright fundamentally integral to the plastics industry.
As simple as the title statement may be, and as oversimplified as the concept is often portrayed, in an industry that is measured continually in cycle times and cost of production (or even the cost resulting from loss of production, i.e., downtime) this is something that should not be overlooked.
Plastics manufacturers are some of the more safety concerned organizations in the US today. The efficacy and safety of the products they produce, whether in medical, automotive or even packaging and consumer goods is of utmost importance to their brand, their bottom line and the lives of those consumers that utilize those products. Within that list of affected audiences, are manufacturing employees.
