Engineering Case Studies: Raise Efficiency, Lower Costs, Maintain Quality

These days, it’s even more important to find ways to cut costs and improve efficiency while maintaining high quality standards. Many of our clients are running at 50% manpower, making business improvement projects even more crucial. For many, engineering projects that have been shelved for years, but never quite got traction, just got real.  We’ve selected a few recent projects turned success stories we think are worthy of your consideration.

The attached briefing provides highlights on five initiatives that addressed issues near and dear to many of us. Real projects that are getting real results. And we’re talking significant return with breakeven in only a few months. Check them out for yourself!

Of course, every shop is different, with demands and complexities that are always unique. Can we save you this kind of money and improve your operation like the Engineering Case Studies we’ve provided here? Quite likely yes, but we can’t know how much until we look at some specifics.

Molders Services is prepared to do just that – no charge. If such a project makes business and operational sense, we’ll propose it for your consideration. If not, we’ll continue business as usual. Fair enough? Call when you have a moment to schedule a visit – 248.930.1444.

Barrel Lead Time Update


Good news for our clients!

The average quoted lead time for barrels has dropped considerably in the last few weeks. Barrels up to 55mm (Group A) are now being delivered in 6-8 weeks and anything up to 110mm (Group B) is now quoting at 11-13 weeks. Larger barrels (Group C) are currently running at 20-22 weeks, down from a high of nearly 40 weeks a year ago. Expect lead times to continue to drop as Xaloy’s facility comes up to full volume production!

And don’t forget that MSI maintains an extensive supply base to provide even faster alternatives when needed. We can deliver re-sleeve services in as little as three weeks and can expedite new barrels with tool steel liners in as little as one week!

Are You Using The Right Screw Tip?

4-Piece and Castle Screw Tips

A good screw tip must provide positive shut off and create a consistent cushion while not restricting flow during recovery. The best tips also inhibit degradation and resist abrasion and corrosion.

How well your screw tip meets those requirements depends on the mechanics of the tip’s seal, its internal flow geometry, and its construction materials.

We’ll tell you how each screw tip style affects production efficiency, output quality, and component durability, and what causes them to fail, so you can lower replacement costs and avoid downtime.

When Good Components Go Bad

Worn screw, still processing

When should a screw or barrel should be replaced?

Keeping a bad component in production flushes dollars down the drain with every part because of reduced recovery output and quality defects, but so does unnecessarily replacing a screw that’s only 50% worn.

Understand the causes, signs and factors of wear, and know what to look for and when your components have “gone bad.”

Stop Waiting for JSW Barrel Feed Castings

JSW Feed Casting

If you have JSW presses on your floor, you know the pain and schedule disruptions caused when changing a barrel.

After the barrel is removed, it must be sent out to have the feed casting pressed off the old barrel and then pressed onto the new barrel, because the OEM will only sell new castings with new barrels — a practice that’s good for them but terribly expensive for you.

There’s a better option. MSI offers new JSW feed castings for sale independent of the barrel. We simply install the feed casting on your new premium barrel and then ship the assembly directly to you – eliminating 2+ weeks of lost production and downtime.

Improved Poppet Nozzles for Milacron PowerPAK

poppet-designAnyone who has experience with Milacron’s PowerPAK line of machines that feature the extruder / plunger setup knows the extruder requires a unique poppet style nozzle that allows it to mate with the plunger barrel. MSI has offered this component for years for substantially less than OEM prices.

Milacron recently redesigned the nozzle to avoid a rash of fatigue failures. Unfortunately, this revised design resulted in an insert-style product reminiscent of the old ball checks sold in the 80s. Aside from multiple leak paths, this poppet has a tiny forward-facing cross section that hampers reliable positive shut-off.

MSI analyzed the failures in the original and subsequent Milacron designs and came up with a superior redesign for this component. Our MSI-manufactured nozzle eliminates the fatigue failure while maintaining the trusted original design.

So if you have a PowerPAK machine and are buying poppet nozzles from Milacron, you are spending more than necessary. MSI has a superior option that costs less! Call us at (248) 585-8120 for pricing and lead time.

A Truly Universal Purge Compound


We’ve seen a near endless number of methods and compounds used to purge barrels and clean screws efficiently. After years of careful consideration and research, MSI has selected a purge compound worthy of inclusion into our product lineup.

It’s called Aquapurge, and while relatively unknown as yet in the US market, we’re confident you’ll enjoy its superior performance and its very competitive price.

It uses a complete mechanical process for scrubbing residues while leaving the metal surfaces in an unworn state. This is achieved by correct selection of filler components; ensuring they are hard enough to breakdown the carbon deposits yet soft enough not to damage metal surfaces.

  • Superior carbon removal
  • Above average color and material changing
  • Effective from 160°C (320°F) to 340°C (644°F)
  • Easily cleaned out by any material, including clear ones as well – (no milky moldings)
  • Can be used as a strip-down material

Contact us or call us at (248) 585-8120 for more information and pricing.

Comparable Quotes For Your Purchasing Department


“Document your purchase requirements and get three bids so a decision can be made in Purchasing for the lowest cost items that meet your criteria.” Sound familiar?

While this may work for commodity products like paper towels, cleaning supplies and pencils, it rarely works well or saves money for buyers of sophisticated components for precision molding equipment.

Read on to learn how we can help ensure your purchasing department — and you — get bids that really can be compared.
