PLS Precision offers engineering and design consulting with a difference most consultancies cannot match: our advice is validated daily on Sinbo's own 518-machine shop floor. ## Why Outsource Engineering to a Manufacturing Group Engineering services outsourcing is a $214 billion market growing at 5.75% CAGR (Market Research Future, 2026), with manufacturing engineering its largest segment. The driver is simple: labor arbitrage plus speed. But most engineering consultancies design in a vacuum — we design against real machines, real tooling, and real cost data. ### DFM That Is Actually Checked Product design is the largest segment of engineering design services (32.5% share, $28.4B in 2025). Our DFM reviews are validated against the machines that will cut the part — not generic guidelines. ### Cost Transparency Because we manufacture, our cost-engineering recommendations come with actual production quotes attached. You see the savings in dollars, not in consultant-speak. ### Speed China's engineering talent density and time-zone offset means drawings reviewed overnight, prototypes in days — the co-innovation model the market is shifting toward. ## Services We Provide Our consulting covers the product development path from sketch to production: ### 📝 DFM / DFA Review Drawing and model review for manufacturability: tolerance rationalization, material substitution, feature simplification, fixturing strategy. Typical findings cut unit cost 15–40% on parts never previously reviewed by a machinist. ### 📊 Cost Engineering & Should-Cost Analysis Bottom-up cost models (material, cycle time, tooling, overhead) for parts you currently buy — the leverage you need in supplier negotiations. ### 🛠 Mechanical Design & Detailing 3D modeling, 2D drawings to ISO/ASME Y14.5 with correct GD&T, reverse engineering from samples, and design-for-process conversion (e.g., machined part redesigned for casting at volume). ### 🧮 Prototyping & Validation Rapid prototypes from our own shop, first-article inspection reports, and design iteration — testing and validation is the fastest-growing segment of engineering outsourcing for a reason. ### 🔌 Process & Tooling Design Fixture and workholding design, machining process planning, and cycle-time optimization for parts moving into production. ### 🔍 Supplier Technical Audits On-site engineering audits of your existing or candidate Chinese suppliers: capability verification, process control review, and corrective-action tracking. ## How Engagements Work Three engagement models, matching how engineering outsourcing buyers actually purchase: | Model | How It Works | Best For | Project-based | Fixed scope, fixed price, defined deliverables (e.g., DFM review of 20 drawings) | One-off redesigns, cost-down programs | Dedicated team | Named engineers allocated monthly, integrated into your workflows and tools | Continuous development pipelines | On-demand / hourly | Hourly consulting for design questions, tolerance calls, supplier disputes | Sporadic expert input, second opinions IP protection is the top concern in engineering outsourcing — we sign NNN agreements (Non-Disclosure, Non-Use, Non-Circumvention) enforceable under Chinese law, and design data is handled on access-controlled systems with per-project isolation. ## Where Consulting Meets Production The unique position of PLS is that consulting never ends at a report. Every recommendation can be executed: 1 ### DFM review → revised drawings → prototype parts The same team that recommends a tolerance change can cut the revised part on our machines the same week. 2 ### Should-cost model → renegotiation or re-sourcing If your current supplier's price exceeds the should-cost, we quote the part — or find and qualify a factory that can hit it. 3 ### Process design → production ramp Fixtures we design are built in-house; process plans we write are run in production with capability data (Cpk) to prove them. This consulting-to-production continuity is why customers use us as a single accountable partner rather than juggling a design firm, a sourcing agent, and a factory. ## Why PLS Precision PLS Precision is the international arm of Sinbo Precision Manufacturing Group — a 34,000 m² CNC manufacturing group in Dongguan with 518 machines and 632 employees. Our consulting team is drawn from that factory's engineering staff: ### 🏭 Practitioners, Not Career Consultants Our engineers program, fixture, and inspect parts daily. DFM advice comes from people who pay for bad tolerances with their own machine time. ### 💲 Real Cost Data Should-cost models built from actual Chinese material prices, machine rates, and tooling costs — current month, not last year's benchmark. ### 🔐 IP Protection That Works NNN agreements under Chinese law, per-project data isolation, and a commercial incentive aligned with yours — we keep your design because your production is worth more than your drawings. ### 🌐 English-Native Communication Dedicated English-speaking project engineers; weekly written reports; drawings delivered in ISO or ASME format per your standard. Frequently Asked Questions What does a DFM review typically find — and save? On parts never previously reviewed by a manufacturing engineer, typical findings include over-toleranced non-critical features, unnecessarily tight surface finishes, hard-to-fixture geometries, and material grades specified beyond need. Across our reviews, rationalizing these points typically reduces unit cost by 15–40% — and the revised drawings come back ready to quote, with GD&T corrected to ISO/ASME standards. How is your consulting priced? Three ways: project-based fixed price (e.g., a defined DFM review scope), dedicated engineer allocation billed monthly, or hourly on-demand consulting. DFM reviews are often credited against production orders placed with Sinbo — if the review leads to manufacturing with us, the engineering cost effectively disappears. How do you protect our intellectual property? We sign NNN agreements (Non-Disclosure, Non-Use, Non-Circumvention) enforceable under Chinese law — stronger in practice than a Western NDA for China manufacturing. Design files live on access-controlled, per-project isolated storage, and only the assigned engineers see them. Commercially, our incentive is aligned with yours: long-term production revenue is worth far more to us than any misuse of drawings. Why outsource engineering to China specifically? China's product engineering services market is $141 billion and growing at 8.5% CAGR — outpacing the global average — because it combines deep manufacturing engineering talent with a significant cost advantage (MarketsandMarkets, 2026). Time-zone offset also works in your favor: drawings sent at your end of day come back reviewed by your morning. The caveat is choosing a partner whose advice is grounded in real production — which is exactly our structure. Can you redesign a machined part for a cheaper process at volume? Yes — design-for-process conversion is a core service. Common conversions: machined to die-cast or powder metallurgy at 5,000+ annual volume, weldments redesigned as castings, multi-part assemblies consolidated into single designs. Each conversion comes with a should-cost comparison and a break-even volume calculation, and we can produce the converted part to validate the design. What do you need from us to start a project? For DFM: 3D models (STEP) and 2D drawings plus annual volume estimates. For should-cost: the part, current price, and volumes. For design work: a functional spec or even a sketch and sample. We return a scoped proposal with fixed deliverables and timeline within 48 hours — the NNN agreement is signed before any detailed files change hands. ## Start an Engineering Consulting Project Send us your drawings, cost problem, or design brief — we'll return a scoped proposal with deliverables and pricing within 48 hours, NNN signed first.
