Design Optimization
We engineer parts and products to ship cheaper, lighter, and more reliably - DFM, FEA, materials, and process trade-offs run by the same team that prototypes and produces them.
Definition
Design optimization for manufacturing is the engineering work of refining a part so it performs against its requirements while costing less to make. It tunes geometry, material, tolerances, and process choice against a real BOM target and a real production line - not a wishlist.
Positioning
Most studios stop at a CAD model that looks correct. The cost of that model only shows up in the first quote from the toolmaker - and by then it is expensive to change anything.
LA NPDT designs the part and the way it gets made at the same time. Material, process, draft, fastener strategy, and assembly count get debated on the workbench, not after the PO is cut.
You get a part that performs to spec and a BOM that survives contact with production.
Who this is for
Design optimization engagements support clients across the lifecycle - from a single problem part to a full cost-down on a shipping SKU.
Core explanation
Real optimization is not a 30-point DFM rubric stapled to a finished CAD file. It is the discipline of moving cost out, performance up, and risk down - knowing that every change costs something somewhere else.
Full-cycle capability
The handoff between design, simulation, and the shop floor is where most cost-downs die. We remove the handoff. The engineer who edits the geometry is in the room when the prototype is cut and when the toolmaker sends the first quote.
Send the file and the cost target. We will tell you what is moveable and what is not.
Process
A repeatable path from a problem part to a manufacturable, cost-effective design. Each step ends with a decision so you control scope, cost, and timeline. Click any step to expand.
We build a cost map of the existing or proposed part - material, process, cycle time, fastener, assembly - so the optimization targets the right driver, not the obvious one.
Deliverable: Cost-driver map and target list.
We sketch the candidate redesigns, score them against cost, performance, and tooling risk, and pick the two or three worth a deeper engineering pass.
Deliverable: Concept comparison and ranked candidates.
Geometry changes are validated in FEA, CFD, or tolerance analysis against the real load case - not a generic safety factor - so the part survives the field.
Deliverable: Simulation reports and updated CAD.
Mold flow, machining strategy, bend allowance, draft, parting lines, and fastener strategy are debated against the production volume and the supplier base.
Deliverable: DFM package and process recommendation.
We prototype the optimized part in a process-relevant way - SLA, machined, vacuum-cast, or short-run molded - and verify performance and assembly before committing to tooling.
Deliverable: First-article part and verification report.
The optimization travels into the tooling kickoff, PPAP-style first-article inspection, and the quality plan so the savings actually show up in the unit cost.
Deliverable: Production-ready package.
Optimize the part you intend to ship - against the process you intend to use - on the line you intend to run.
How we approach design optimization
Concept development
Before any tool is cut, we ask whether the part as scoped is the right part to build at all. Most cost-downs reveal an assembly-level redesign that beats any single-part optimization - and that is the point.
Cheap kills, cheap re-scopes, and cheap consolidations are the goal of this phase. Expensive surprises in tooling are what we are here to avoid.
Prototyping
We prototype the optimized geometry in a way that looks like production - so the data is honest. SLA for fit, machined for stiffness, vacuum-cast for assembly, short-run molded for cycle and quality.
Why it's different
| Area | Generic DFM checklist | LA NPDT optimization |
|---|---|---|
| When applied | After CAD is frozen | From concept onward |
| Cost analysis | Quoted by toolmaker | Modeled against BOM target |
| Performance | Assumed safety factor | Validated in FEA / tolerance stack |
| Process selection | Default to molding | Picked against volume and material |
| Hand-off to production | Drawing pack thrown over the wall | Same team into tooling and first-article |
| Outcome | A part that fits | A part that ships at the right cost |
One team. One brief. The geometry and the process are the same project.

What clients say
Words from product leads and operators who used our engineering to take cost out and performance up.
They cut 28% out of our unit cost on a part we thought was already optimized. The redesign passed FEA on the first pass and the toolmaker quoted lower the same week.
R. Mendes
Director of Engineering — Consumer hardware OEM
We had two firms tell us our bracket could not get any lighter. LA NPDT topology-optimized it, ran the FEA, and shipped a part 40% lighter that passed every drop test.
T. Whitaker
VP Operations — Industrial equipment maker
Our pilot run had a 12% scrap rate. They re-engineered the parting line and the gating, ran a process-relevant prototype, and the next run came in under 2%.
L. Okafor
Head of Supply Chain — Smart device manufacturer
They did not just trim the BOM. They re-scoped the assembly, killed three fasteners, and gave us a product that is faster to build and easier to service.

Funding & business support
An aspirational gross margin is not a margin. But a documented BOM, a validated process choice, and a tooling plan - tied to a working prototype - is the artifact that closes investors and protects the launch P&L.
Pitching? Bring engineering an investor can stress-test.
Why it matters
Done right, optimization compounds - cheaper to make, faster to assemble, less to warranty, easier to scale.
Material, cycle time, fastener count, and assembly steps tuned against a real BOM target - not a wishlist.
Stiffness, fatigue, and tolerance stacks validated in simulation before tooling - not discovered in the field.
Process selection, tooling risk, and quality plan all packaged so the savings actually land in production.
From the journal
Field notes from the studio - how we run cost-downs, FEA reviews, and process selection when there is a real product on the line.
Most cost lives in three or four lines of the BOM, not where the team thinks it does. Here is how we map it before we touch the geometry.

FAQ
Design optimization for manufacturing is the engineering process of refining a part or product so it performs as required while costing less to make. It tunes geometry, material, tolerances, and assembly steps against real production constraints and a real BOM target.
Generic DFM is a checklist applied late. We run optimization as a continuous loop - mechanical, materials, and process engineers iterate the part against cost, tooling, and yield targets from concept onward. The result is a part that is cheaper, lighter, or more reliable on purpose, not by accident.
The earliest gain is at the concept stage, before tooling. The next big lever is at the prototype stage, before tooling is cut. Optimization is also worth doing on a shipping product when volume justifies a cost-down, a redesign for a new process, or a quality fix.
On parts that have never been touched by a manufacturing-aware engineer, 20-40% reductions in unit cost are common. On already-optimized parts, 5-15% is typical, often paired with weight, cycle-time, or quality improvements that pay back in service.
Yes. The same team that optimizes the design prototypes it, runs first articles, and supports short-run or full production. Findings flow straight from the workbench into the tooling and quality plan instead of being thrown over a wall.
Injection molding, CNC machining, sheet metal, die casting, additive manufacturing, and overmolded assemblies. We optimize material selection, wall thickness, draft, parting lines, fastener strategy, and process choice together - never in isolation.
If you need design optimization that actually shows up in unit cost, performance, or yield, the next step is a short engineering review tied to a real BOM target. LA NPDT delivers both under one roof.
