Injection Molding

LPIM (Low Pressure Injection Molding) – Structural Web Injection Molding

Structural Web molding technology is a variation of Low Pressure Injection Molding (LPIM) that was developed by Milacron as a proprietary molding process on our LPIM machines. It is a process that is well suited for large part/large shot sizes with good part surface aesthetics and low molded in stresses. The process also creates a part with a dual wall section (hollow) allowing for 10% to 30% part weight savings over a solid molded part with the same part geometry.

What Mold Do You Fit Into?

The plastics industry, understandably so, is a rather diverse industry; not unlike other large global industries. It is comprised of companies and organizations of all shapes and sizes, usually differentiated by organizational structure or revenue.  Aside from the typical size comparisons of companies, the diversity extends outward in a great number of ways and categories (i.e., output product type, machine type, injection/extrusion/blow, industries serviced, supplier/mold maker/machine manufacturer/part molder, etc.); so much so that I wouldn’t pretend to be able to cover even a small fraction of it in this post. What I do want to chat about this month is more in line with the self-assessment or self-classification of the company that you currently operate. In essence, let’s talk about “What is your buying type”?

5 Things to Consider While Attending NPE 2018

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?

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.

Buying Time

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.

Choosing the Right Screw and Barrel

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 Value of 1 Second

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.
