DEWIN sources custom mechanical parts and assemblies from vetted factories in Vietnam and China -- giving US and European customers a built-in Plan B without managing two supplier bases.
The Problem with Your Current Supply Chain
Procurement managers at US and European manufacturers tell us the same story. Their suppliers look good on paper -- until production starts.
Get a Second Opinion on Your PartsSuppliers miss critical drawing requirements. You're stuck in costly rework loops before production even begins.
No proactive updates, no early alerts. You find out about delays when your production line is already waiting.
With US tariffs on Chinese goods at 45%+, a single-country strategy is no longer viable. You need a Plan B -- now.
Suppliers can't provide PPAP, COA, or dimensional reports. Your quality team is left guessing.
Vietnam + China Dual Sourcing
Split production between Vietnam and China based on cost, tariff exposure, capacity, or geopolitical risk -- managed by a single point of contact.
Procurement managers relying solely on China are absorbing margin losses. DEWIN's dual-sourcing model lets you split production strategically -- without doubling your supplier management overhead.
Full-Scope Manufacturing Services
DEWIN is not a factory. We're your engineering-backed supply chain team -- matching each project to the right factory, then managing quality, logistics, and documentation end-to-end.
Turning, milling, and grinding for complex geometries. Steel, aluminum, titanium, brass, and engineering plastics.
Aluminum and zinc alloy die casting with high-life tooling. Ideal for complex housings and brackets at volume.
Sheet metal fabrication for brackets, enclosures, and structural assemblies. Progressive and transfer die tooling available.
Engineering-grade plastics: PA, POM, ABS, PC, and PEEK. Insert molding and overmolding available.
One-stop trade service: factory audits (QCLDM scoring), PPAP documentation, in-process QC, final inspection, and door-to-door logistics.
Proven playbook to relocate full production lines. Vietnamese team communicates directly with local factories -- no language barriers.
How We Work
Submit drawings. Our engineers review for manufacturability issues before quoting -- catching problems that cause sample rejections later.
We score factories using our QCLDM audit system -- Quality, Cost, Lead time, Delivery, Management -- and match your project to the optimal supplier.
Our local team monitors production at the factory, not just final inspection. First Article Inspection, in-process checks, and dimensional reports included.
We handle freight, customs documentation, and last-mile logistics. You receive parts, COA, PPAP package, and invoice in one shipment.
DEWIN identified three critical tolerance issues in our drawings before production started. That alone saved us two rounds of sample rejection and at least six weeks of lead time. Their Vietnam team communicates like a local -- because they are.
Real Results
Why DEWIN
DEWIN acts as your embedded procurement and engineering team in Asia. We don't just find suppliers -- we qualify them, monitor production, handle documentation, and deliver to your door.
One contract, one contact, two countries. Split production strategically without managing multiple supplier relationships.
Our engineers catch drawing issues before production starts. This is why our clients report fewer sample rejections and shorter time-to-production.
7 local Vietnamese staff communicate directly with factories in their native language. Zero translation gaps, zero miscommunication.
Flexible O/A terms up to 90 days protect your cash flow while production is underway -- rare if you work with factories directly.
Get A Solution in 24 Hours
Share your part drawings and requirements. Our engineering team will review for manufacturability and send you a timeline within 24 hours -- no commitment required.
