PSI Most Commonly Asked Questions


Most Commonly Asked Questions

  • What is your typical turnaround time on an average project?

    Average is difficult to define given the diverse nature of materials and processes utilized at PSI. We consider ourselves as a "Quick Turn" operation. Often providing much shorter lead times than typical industrial cutting or machining operations. Additionally giving the fact that we have so many processes in house it allows us to do the entire project (or a large piece of it) saving the customer the time and inefficiencies of utilizing several companies.

  • What type of materials do you process?

    The range of materials we process is extremely diverse from Industrial Ceramics to Carbon Fiber, from mild carbon steel to titanium is common practice here at PSI.

  • Can you provide design and engineering services or do you just produce parts to customer determined specifications?

    We are happy to take either approach. We have extensive design and engineering capabilities. We can start with your idea or casual drawing and ultimately produce parts or assemblies to your satisfaction.

  • What are your shop rates?

    Rates vary with process and we employ many processes at PSI. Basing part or project costs on shop rates assumes all similar companys operate at same level of productivity employing the same level of employees and equipment. Certainly that is not the case. We prefer to provide pricing upon detailed review of your needs. This approach is much more valuable to the customer.

  • Does PowerStream Industries provide the material or does customer need to provide it?

    The vast majority of our customers rely on us to provide all associated materials. Our high volume purchasing of metals, plastics and composites typically allow us to provide the material with very modest mark ups for less than the customers providing it. If you choose to provide the materials that is absolutely fine. Please ask us to provide information on the most efficient material size and configuration for the job.



Most Commonly Asked Questions

  • Why not use servo hydraulics actuation like the others?

    In-fact all the other manufactures producing full car dynamic test rigs for motorsports use servo-hydraulic systems. They have been producing basically the same system for over 20 years. Throughout the years the control valving systems have gotten slowly better. They have gone beyond the "Bang Bang" valving systems that have been in use for so long. However the level of control and precision is and will continue to be way behind our much more modern and advanced systems. Producing a capable dynamics test system outside hydraulics requires one to utilize the very latest in electromechanical and electromagnetic systems. With this well engineered and fully developed system you have testing capability that is much more precise, easier to use, less expensive to produce and much more environmentally responsible, all this while costing less than 50% as much to operate. We believe developing our latest systems without providing our customers the very latest in technology, superior function and the lower in operation cost would be irresponsible. It is important to us for our customers to know that we provide the latest in proven technology to provide them superior test solutions.

  • How can Geo Systems Discovery diagnose so many different areas of kinematics, compliance and dynamic movements. It seems other systems focus on one or two areas. Do the GEO Systems test platforms give up something to gain the versatility?

    It is true that 7 posters focus exclusively on dynamics testing in vertical motion and K & C systems focus on kinematics and compliance issues. Also it is true that the Geo Systems "Discovery" is the only system that provides crucial data in the areas of kinematics, compliance and dynamics. The architecture of the Geo systems discovery is unique. It is the only system designed from ground up as a motorsports test system. It is not a OEM test rig modified to work in the motorsports realm as are the others available. In design we responded to what motorsports teams needed most, this was time. Developing a system that allows so many conditions to be analyzed in one vehicle set up was the closest we could possibly come to providing them time in a box. Testing that would typically take 2 days or more can be accomplished in often half the time. There is no penalty for this.

  • You indicate elsewhere in your promotional materials that utilizing the GEO Systems test platforms was in some way more environmentally responsible than some of the other systems being used in motorsports. How can that possibly be the case?

    That point was made in comparing the dynamic operations of the GEO Systems test platforms with the commonly used servo hydraulic 7 poster test systems. To operate the hydraulic systems requires a large hydraulic power unit, these units contain approx. 300 gallons of hydraulic oil in a single test system. Depending on the system and its use this oil is replaced approx. every 1-3 years. Consumption could be higher with any malfunctioning valves, fitting or hoses of which there are many. The Geo systems use no hydraulic oils, no consumable fluids of any type. Compare this to a 10 year operational time of a servo-hydraulic system that may utilize in excess of 800 gallons of hydraulic oil that most be disposed of. Multiply that by the number of hydraulic based test systems in use and its a disturbing situation if you are concerned about the environment. Our systems also consume less than a 3rd of the electrical energy of a servo hydraulic test system, again extending that savings in resources over a large number of units in use.

  • With the GEO Systems being built differently using different technology than the established manufactureres why should someone be comfortable with your components being sure we won't be stuck in a situation that we can't get your parts?

    That concern is understandable. The components were very carefully chosen so they are not specific to our use. We have chosen Mitsubishi as our data and control system partner the largest supplier of these high technology systems in the world. Further these major components are inventoried by Mitsubishi in almost every major country in the world. So in fact the parts are much more readily available than offered by any other test system manufacturer in the world.

  • You mentioned prices associated with the test platforms but not about installation or excavation and costs associated with the under floor materials and labor. What should be budgeted for installation?

    We did not mention these costs due to the fact they are completely unnecessary. The GEO Systems test platforms mount to the floor surface. Depending upon the functionality of the system they may require an isolation pad system, a very minor cost in the scheme of things. Installation and training of these systems is typically completed in 2-5 days dependent upon machine functionality.
