Introducing the RSPro800 3D Printer!

IMPM has increased our 3D printing capabilities with the introduction of the RSPro800 SLA, 3D printer.  The new machine has a build envelope of 31.5 ” x 31.5″ x 21.7″, over double the size of our previous build envelope.  The SLA process produces the most accurate parts with the finest finish, so while IMPM never shied from large parts, this allows us to do so more easily with a time and cost savings benefit for you.  We are running the Somos EvoLVe resin in the RSPro800, a sturdy material designed to provide a little more functionality and ease of post-processing.  We are very excited with the addition of this new machine and cant wait to use our big machine to materialize your big ideas.



IMPM will be at the Design-2-Part and SEMA shows this fall!

Come chat with IMPM about your prototyping and molding needs at the Design-2-Part and SEMA shows!

The Design-2-Part show will be October 10-11 at the Raleigh Convention Center located at 500 South Salisbury St, Raleigh, North Carolina 27601; IMPM will be exhibiting at booth 333.  The Design-2-Part show is one of America’s largest design and contract manufacturing trade shows, exhibiting the nation’s most proven manufacturing innovators.  Find out how IMPM will take your company all the way from the product development stages into production.

IMPM will also be exhibiting at the SEMA show October 30th-November 2nd at the Las Vegas Convention Center, located at 3150 Paradise Road, Las Vegas, Nevada 89109; IMPM will be exhibiting at booth 15011 in the West Gate.  The SEMA show is the nation’s largest automotive show, displaying not only car manufacturer’s new vehicles, but all the companies that support the automotive industry as well; this includes aftermarket parts, new tools, electronics, performance parts, etc.  IMPM’s leading-edge silicone tooling technology is providing some of the best custom, polyurethane parts for the automotive industry, allowing car manufacturers to break free from traditional design boundaries and provide next level designs.  Come check out what IMPM is doing for the industry.

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.
