RTV Molding And Cast Urethane Prototypes || InterPRO

Very good service, very good models. They will go out of their way to get a job done. What more could you ask?

Just got some feedback from our customer and the results of your efforts and service were great.
Bottom line is that you guys did a great job.

We have the parts now. They are excellent quality. Our customer has made a change to the parts and we will be
redesigning this case and cover. Thanks for the quick response.

It is always a pleasure to work with all the people at Interpro. I can give them a project and not worry about
the quality of the prototype or the delivery times.

Very Pleased. Service is always great. I appreciate Interpro willing to take it upon themselves when a fit is tricky.
You didn't have to invest in a quick build to help our project but you did. Much Appreciated.

It was great. Upload a part. 2 days later it comes in a box. Thanks for the quick turnaround!

Though lowest bid is not my primary goal, I get quality and delivery with a low price.

You are our most trusted model company.

It's great to have a company that is flexible to work with and usually
beats delivery and quality promises. Keep up the good work.

EXCELLENT! Thanks for another great part.

It has always been a pleasure working with your company and employees. Every prototype that we have
received from you has always been excellent and very professional looking. Thank you for all your help on our past projects
and we look forward to working with you again in the near future.

Great service, competitive prices, and the people at Interpro have always been outstanding to work with.

We always appreciate the quick response, fast delivery and high quality of the prototypes.
We also greatly appreciate how everyone at InterPRO works hard to get the part to the customer and get done right.

InterPRO was a great find. I am happy with them and look forward to a long business relationship.

Interpro has consistently provided good service and seems to understand our needs.
Thank you again for the great job! We're all very excited about the print.

Everything is always on time and the parts always meet our expectations.
Please keep up the good work.

THIS WORKED OUT GREAT FOR US. I DEFINITELY PLAN ON USING YOU GUYS FOR EVERY NEW DESIGN WE COME UP WITH.

INTERPRO SERVICE IS CONSISTENTLY HIGH QUALITY. THEY ARE ALWAYS GOOD TO WORK WITH AND ACCOMMODATE WHATEVER IS NEEDED.

YOUR COMPANY IS VERY EASY TO WORK WITH. THE ORDER WENT SMOOTH AS IT NORMALLY DOES. THE QUALITY IS AS GOOD AS IT GETS.

RTV MOLDING AND CAST URETHANE PROTOTYPES

In under two weeks, InterPRO can deliver plastic prototypes with material properties similar to production plastics.

We do this with RTV molding, which produces cast urethane or epoxy prototypes with the look and feel of injection molded parts.

The benefits of RTV (Room Temperature Vulcanized) molding are:

Functional prototypes with complex features

Fast delivery compared to injection molded prototypes

Relatively low cost compared to direct RP

Very low cost compared to injection mold tooling process

A wide range of material properties to choose from

Cast-in color that is blended to your specification

Accuracy that is on par with rapid prototypes

Zero Draft and/or small undercuts are not a problem

Shore A, Shore D, bio-compatible, flame-resistant, UL rated and clear materials are available

Inserts can be cast into the part for maximum strength

Delivery of parts usually in 2 weeks or less

To produce molds using the RTV molding process, we start with a master pattern that is made with RP or CNC.

Liquid silicone rubber is poured around the master pattern. Once the silicone is cured, the mold is cut open to remove the master pattern. The mold is then used to cast the urethane parts.

InterPRO casts all parts under a vacuum with molding machines using computer control. This allows us to produce produce void-free castings with consistent properties in each part.

Colors are cast in, matching your specifications. Paint, texturing and/or graphics can be added.

Available Materials in Shore A & Shore D

We can find materials to match whatever physical properties you are looking for. Our most popular two-part urethanes are F-60 (createss a flexible part) and TC-850 (creates an extremely rigid part.)

See the specifications for F-60 here. See examples of F-60 in action in our gallery under Ducts.

See the specifications for TC-850 here.
