The Problem
Mechanical engineering services work best when the team knows the rules your industry lives with. A bracket on an aircraft, a frame on a mining truck, and a vessel in a pharma plant share the same physics. But they face different loads, codes, reviews, and costs of failure. A generic answer misses the constraint that matters most. Then the design comes back at review, in test, or in the field. Fixing it there costs far more than getting it right on paper. The fix starts with knowing the rules.
The PPS Approach
We group the industries we serve into three bands. Mobility and defense covers aerospace, automotive, mining, and marine. Process and compliance covers pharma, EtO sterilization, and cement. Energy and facilities covers power generation, air pollution control, and data centers. Each band shares the same kinds of reviews and risks, so lessons carry across. Every band runs on the same team, methods, and gates.

Mining · Heavy equipment
Pharma · Process systems
Power Generation · Plant equipment
Why does equipment design need process knowledge? A reactor, a kiln, or a cooling unit only works if it fits the process it runs. Our engineers work on both sides. They work on the process inputs, such as flow, mixing, heat transfer, and scale-up data. They also design the equipment that delivers them. Neither side works well without the other. That is what our equipment design services mean in practice. We engineer it. Our partners build it. You run it.
PPS takes the designs we engineer as far as you need, from concept to the start of production. We never compete with the manufacturers we partner with. Our mechanical engineering design services work in three models: OEM Partner, Operator-Led, and Joint Program. For OEMs, that means OEM engineering services when you need them: an extra team for design, analysis, and release. The right model depends on your needs, and the free assessment is where we decide. You approve the data at each gate. You own the IP by default, set in your contract.
Facts about how we work, not project results. One team engineers your product from analysis to delivery, and calculations carry a PE stamp where required.

Which industries do your mechanical engineering services cover?
Our mechanical engineering services cover ten industries in three sectors. Mobility and defense covers aerospace, automotive, mining, and marine. Process and compliance covers pharma, EtO sterilization, and cement. Energy and facilities covers power generation, air pollution control, and data centers. Each page shows the equipment we engineer there. The same physics shows up in every industry, but the rules do not. Take a bracket on a jet, a frame on a haul truck, and a pharma vessel. Each faces different loads, codes, and costs of failure. An EtO sterilizer must meet the EPA's emission standards for sterilization facilities. Generic answers miss the rule that matters.
Each industry page is built around the equipment and the review it must pass. If your industry is not listed, that does not rule it out. Our methods stay the same: FEA, CFD, design, and testing, applied to the loads and codes your product faces. Send the problem and the rules you work under. The free assessment tells you whether the work fits and where to start.
Do you know the codes and reviews in my industry?
Every industry has its own rules, and our mechanical engineering services start from them. Aerospace has design reviews. Ships face class rules. Pressure vessels face ASME Section VIII. Pharma faces validation, and emissions face permits. We agree on the rules and the reviewer before we model anything at all. A design made to the wrong rules comes back at review, often after tooling or fabrication has started. In pharma, the FDA's process validation guidance treats validation as a lifecycle, so a weak change can reopen closed work. Each late question slows every step after it. The cost lands on your schedule, not just your budget.
We write the analysis and documents to answer the reviewer's questions before they are asked. We prepare the engineering that supports approval. The approval itself comes from your customer, inspector, class society, or regulator. PE-stamped calculations are available where the code requires them. If your rules are new to us, we say so in the assessment, not on your project. You approve the data at every gate.
Can PPS work with our OEM or manufacturer?
Yes. Mechanical engineering services from PPS fit the partnerships that are normal in every industry we serve. We work in one of three models. As your OEM partner, we act as your engineering team. Operator-led, we design the equipment and work with the builder you choose.
When design, build, and test sit with different companies, problems pass back and forth. The builder works from an old drawing, and each party defends its own scope. The Department of Defense's IPPD Handbook organizes programs around integrated product teams for this reason. In a joint program, the operator and the OEM work with us in one loop.
We engineer the design and coordinate the builder in one loop. Bring your own manufacturer, or work with our network of fabricators, machine shops, and test labs. You decide how far we take the design, up to the start of production. We never run production, so we never compete with your OEM. NDAs cover every party, and you own the IP by default, set in your contract.
What do you need from us to start?
To start a project with our mechanical engineering services, send what you have, in any format. That usually means CAD, drawings, or the parts themselves, plus the loads, operating data, and conditions. Add the codes and reviews that apply, any test results or failure history, and your targets for cost, life, or schedule. Photos help too. Missing data is the most common reason engineering projects stall, because a model built on guessed inputs gives a guessed answer. That is why we don't start the work until every data set is in.
Once it is, the first step is a free assessment of your project scope. We confirm what the work can and can't answer, and tell you what is still missing. Then we send a roadmap proposal with scope, targets, and approval gates. Every project is scoped on its own, so the roadmap sets the schedule, not a stock promise. NDAs are available before you share any files. For gaps in material data, NIST material measurement data is a good first stop.
Who owns the design and the models?
You own the design, the drawings, and the models from your mechanical engineering services project by default, as set in the contract. When an OEM or partner manufacturer is involved, the contract spells out who owns what. Some firms keep the models, or license them back to you, so every later change sends you back to them. That locks your product to one vendor and makes design reviews harder, because your team can't open the evidence behind the decisions. You receive the native CAD, the drawings, the simulation model files, and the documented results. Your engineers can then check the work, rerun a load case, or hand the package to a supplier or customer.
We sign mutual NDAs before any of your data is shared, and your files stay in our controlled project folders while we work. If your program has export-control or customer data rules, tell us at the start and we will set up the data handling to match them. For defense programs, the State Department ITAR guidance sets the rules we follow.
What happens if a prototype fails in test?
If a prototype fails in test, we find out why and fix the design. Hard engineering carries unknowns on any project: real loads, material lots, and assembly effects never match a model perfectly. With mechanical engineering services from PPS, you approve the data at each gate. A test result is then checked against predictions you have already seen, not a black box. A failure in test is data. It shows which assumption was wrong: a load, a material property, or a boundary condition. That data improves the model and the design.
When testing is in scope, we plan the test to confirm the margins that matter most. Then we correlate the model to the results, following ASME verification and validation practice. If the miss was ours, because something slipped through our QC review, we fix it. If the test uncovers a condition nobody knew about, we scope the change with you and update the roadmap. Either way, you get a clear answer and a path to a design that holds.
How are mechanical engineering services priced?
We price mechanical engineering services to the value they deliver, not the hours we log. Hourly billing rewards extra iterations, so the cheapest quote often becomes the most expensive project once tooling, rework, and field failures show up. Our incentive is to get the design right the first time. We engage by fit, not as a ladder. Gold (from $35K): you have one project and need help with it. Platinum (from $15K/mo): you have recurring work at a steady rhythm. Diamond (from $800K/yr): you have a long development program, often multi-year.
Gold is never required, and some clients start at Platinum or Diamond. These are starting points, not quotes; your roadmap sets the price. We price to the value we deliver, not the hours we log. If the value isn't there for you, we'll say so in the assessment. Our engineering consultant pricing page explains how each collection works in more detail.
