3D Printing

Will 3D printing affect your manufacturing processes?  If not today, probably in the near future.  Currently Ford Motor Company utilizes 3D printing for test parts.  The current cost is still more than traditional manufacturing, but that is quickly changing as printers and materials get cheaper and  printers get faster.

How can we embrace these changes so that we are not left behind?  Learning about new technologies and integrating them into your 12-24 month business plan will ensure you know that answer.  Make sure that it will improve your production, increase sales or reduce R & D costs, before you invest.  There are many resources out there for you to utilize. Look at local and state agencies, SBA and even your competition to determine if you need to make 3D changes.  Below are a couple of articles that discuss the future of 3D printing, you might enjoy.




How Defoamants Work

How Defoamants Work
As air becomes entrained in oil, air bubbles attempt to rise to the surface. While a bubble is rising through the oil, it passes through and picks up any number of defoamant additives that are blended into the lubricant. Defoamants are a little different than most additives in that they are suspended in oil rather than dissolved. This is important because defoamants would lose their ability to minimize foam if they were in a dissolved state.

Once an air bubble traps some of these additives in the bubble wall and finally reaches the oil’s surface, the defoamant works to impair the film strength of the bubble wall. Think of it as providing a weak spot in a chain. The interfacial tension of oil is relatively high, but the interfacial tension between the oil and the defoamant droplet is much lower. At this point, the additive spreads and ruptures, allowing air to spill into the atmosphere as the bubble bursts and the stable foam on the oil’s surface is minimized.

In a perfect world, defoamants would do their job, and foam would never be a problem. However, these additives can lose their effectiveness as a result of a number of issues. Perhaps one of the most widespread is the contamination of the oil. Any contaminant that impairs the oil’s surface tension can diminish the performance of the defoamant. Water is one of the most common contaminants that reduces surface tension and leads to excess foaming. Other contaminants include detergents, solvents, fuels and oxidation byproducts. By keeping out contaminants and maintaining clean oil, you can proactively manage foaming.

Another reason defoamants become ineffective is because of their removal from the oil. This can occur due to filtration, which will be discussed later, or from the oil being stored for an extended period of time. Since these additives are suspended and not dissolved, they are prone to settling out of the oil. Without sufficient agitation, defoamants may not fully suspend when the oil is added to a machine, especially if the oil has been in storage for a considerable length of time. This is why performance testing of stored lubricants is highly recommended. It is also one of the many issues that can arise from lubricants exceeding their shelf life in storage.

When should you change your metalworking fluid?

You should check your machining fluids on a consistent schedule.  Depending on how much manufacturing you do, would determine how often you change your fluids.  According to OSHA’s website:https://www.osha.gov/SLTC/metalworkingfluids/metalworkingfluids_manual.html https://www.osha.gov/SLTC/metalworkingfluids/metalworkingfluids_manual.html

there are many signs that a fluid has undergone changes and is no longer safe to use.  It can become a hazard in you facility. If one or more of the following changes occur, it should be replaced.

  • Low sump level. Check the sump level at the start of the shift. A low sump level (30% below the full mark) shows metalworking fluid loss or water evaporation (increasing the concentration of chemicals present in the MWF). The proper concentration should be verified with a refractometer.
  • Abnormal fluid appearance. Does the color of your coolant look normal? If the fluid turns gray or black, then bacteria are often present. If the fluid picks up a yellow or brown tint then tramp oil may be present.
  • Foul smell (rancidity). If it smell bad, throw it out!  It usually means that there is uncontrolled micro bacterial growth in your fluid. These organisms can be released into the air and is a health hazard.
  • Floating matter on the fluid. If the fluid has floating chips, stringy material or mold growth, this is not normal. Try to remove as much as possible with a skimmer or have it pumped off. Proper and consistent maintenance of the filtration system and oil skimmer are necessary to assure that proper  function of machinery.
  • Tramp oil floating on the surface.  If there is too much tramp oil present, skim or pump the surface oil to remove it. These oils are not developed with repeated skin contact in mind, and some components of these machine lubricants are highly irritating to the skin. Tramp oils can be a significant carrier of metallic fines, which can be deposited on the skin and cause mechanical irritation and cause dermatitis.
  • Dirty machines or trenches. This could mean that the emulsion is becoming unstable, the cleaners in the fluid have been depleted, the contaminants are being deposited from the fluid, there is filter failure, or there is poor housekeeping.  Premier Poly-Cut™  will actually clean out your machine.
  • Other things to consider
  1. rust or corrosion of the machine tool or of the part produced;
  2. staining of the metal machined or machine tool;
  3. tool failure due to the loss of performance additives;
  4. growth of fungi that block fluid flow;
  5. change of fluid viscosity (thinner or thicker);
  6. accumulation of water at the bottom of the oil sump drain, in straight oils;
  7. dirt and grit suspended in the fluid; and
  8. failure at the workpiece-tool interface (for example, burning of a ground part due to excessive heat build-up).

Veteran-Owned Small Business

Local and Federal governments want to do business with Veterans.  For those companies that want to pursue government contracts, it is smart to partner with a  certified Veteran or Service Disabled Veteran Business.   There are millions of dollars in contracts that are set aside just for these Veterans.

It takes a lot of patience to fulfill all of the requirements to be designated as a Certified Veteran Owned Business.  That is because when the program was first introduced, it was fraught with fraud.  So, those businesses that were legitimate now have more hoops to jump through.  But when you work with a Veteran, not only are you helping those that fought for your freedom and liberty, but you are also ensuring that these small business owners are given a more level playing field against the bigger players.

With a Veteran Partner, you reduce your competition.  Less competition can lead to more contracts.  So think about the 6000+ certified Veteran businesses that you might want to partner with.  Tullco. Inc. is a certified Service Disabled Veteran Owned Business (SDVOB).  Learn more about Veteran certification http://www.vetbiz.gov.  #veterans
