Come See IMPM At The D2P Show In Atlanta!

Come see IMPM at the Design 2 Part show in Atlanta, Georgia on March 29th & 30th where we will be exhibiting our rapid prototyping and low volume production capabilities.  The D2P show is a great show to stay progressive with current manufacturing trends and find suppliers for your project, and the best part is it’s free to attend!  The show will be held at the Cobb Galleria Center at 2 Galleria Parkway, Atlanta, Georgia 30339, from 9:30 A.M. to 3:00 P.M. both days.  IMPM will be at booth 212.  Contact us to get your free registration form.

We look forward to seeing you there!

Polyester Resin (Fiberglass) Casting vs. Urethane Casting

In the product development world, many large prototypes are produced by casting a polyester resin with a filler for reinforcement, more commonly known as fiberglass.  This process is popular as materials are comparatively cheap and finished parts tend to have moderate tensile strength.  Often, however, fiberglass prototypes wont mechanically resemble their production counterparts.  For example, a fiberglass prototype won’t have nearly the same properties of the same production part that’s from an injection molded polyethylene material.  This may cause issues when testing prototypes for functionality, as you don’t get true representation of engineering intent.

For a better embodiment of production properties, urethane castings should be used to produce prototypes.  Urethane resins are constantly being improved and come in an extensive array of mechanical properties ranging from elastomeric, high rigidity, high heat resistant, high impact resistant, and various regulatory ratings like UL ratings and FDA compliancy; a lot of urethane resins are produced to mimic production plastics.  The silicone used to make the molds and the urethanes are both extremely impressionable, so the appearance of the parts can be of much higher quality if the master pattern used to make the mold is of high quality.  However, the biggest advantage casting urethane has over fiberglass is repeatability.  Once a mold is made, it takes minimal effort to produce parts, unlike fiberglass where the filler must be manually applied for every casting.  Urethane castings give you the ability to produce production quality parts that represent true engineering intent.

What You Can Expect With Aluminum Tooling

Great read about the expectations of aluminum tooling for injection molding.

Aluminum tooling is an under utilized method of mold making when it comes to injection molding.  IMPM has utilized aluminum tooling for over 20 years and has been able to fabricate molds at much lower cost and much shorter lead time than the competition.  The article in the link above outlines how other companies have utilized aluminum tooling and benefited greatly.  Definitely worth a read.

Cast Urethane Applications: Medical Devices

Congratulations! You’ve spent months designing the next medical device that’s going to change the world (or more realistically a very specific community in need of a very specific type of medical attention) and now you’re ready to test your design. What now, do you spend a ton of money on hard tooling for a device that might sell 80 units annually? Do you compromise your design to fit the model of a company promising the lowest cost injection molding tooling? Or do you utilize the best option for low-volume production? The silicone tooling and cast urethane process is the perfect fit for these types of jobs. For a fraction of the tool cost (generally thousands of dollars vs. tens of thousands of dollars), you can still achieve a production quality part that still has desired mechanical properties, the repeatability of other traditional molding processes, and a near impossible to beat lead time. Silicone tools do have a smaller yield, IMPM guarantees 100 shots from its silicone tools, which makes it perfect for these small production runs. Sure, not every medical device is going to have such small production quantities, but this process still allows you to produce the highest quality prototype (form, fit, function) without breaking the bank. Urethanes are produced to mimic almost all production materials, including materials that are:

• FDA Compliant
• Flame Retardant
• High Heat Resistant
• High Impact Resistant
• And Much More


IMPM has been the leader in the silicone tooling and cast urethane process for 25+ years.  Let us hear your concerns so we can put your mind at ease.

Additions To Our Tooling Capabilities!

We are pleased to announce the arrival of two new Haas VF2SS CNC Machines along with a new Haas TL1 lathe. The additional equipment gives IMPM the ability to process your aluminum tooling for product development and low volume production runs quicker and more efficiently. With over 40 years of experience rest assure that all aspects of your project will be handled and streamlined from start to finish. Some Advantages of aluminum tooling:

  • Tools can be created relatively inexpensive for limited runs during the testing process of Design and/or Material evaluation.  (no cooling lines, hand load, ect.)
  • Tools can be designed for above testing but with ability to be converted to a production tool.
  • Production tools have the life of 100,000 units.
  • Typical turnaround time on tooling is 3-4 weeks based on tool requirements.

IMPM stocks various injection molding materials but will have your required material in inventory prior to the completion of the tool.

Coupled with the in-house injection machines: 45 ton Arburg, 110 ton Demag & 170 ton VanDorn you now have the ability to get quick turnaround injection molded parts.

IMPM has always been the leader in product development using silicone tooling and cast urethane parts, guaranteeing 100 shots from our silicone tool. We now offer you another avenue to for your product development needs. As always we look forward to providing you with outstanding service and quality parts. Let IMPM handle your next project.
