Product Manufacturing Scope
Explore SUNDA’s four core product lines, built for OEM and ODM requirements.
Car Chargers
Single, dual and multi-port car chargers. We build PD 3.0, QC and PPS versions up to 230W. Housing color and logo follow your spec.
Wall Chargers
Travel and desktop wall chargers, with GaN options available. We certify them for the EU, US and China markets. Port count and plug type are yours to choose.
Charging Cables
USB-A, USB-C and Lightning cables. We match length, gauge, braiding and connector to your device. Every cable is load-tested before packing.
Phone Holders
Magnetic and clamp car mounts. We run your color, packaging and branding. In-house tooling keeps the fit consistent.
Manufacturing
In-House Manufacturing Processes
SUNDA controls key production stages inside our own factory. Your order moves from tooling to packed carton without leaving the building. That keeps lead times short and quality checks in our hands.
Tooling & Mold Making
SUNDA uses CNC, EDM and wire-cutting equipment to produce tooling and molds in-house.
Injection Molding
SUNDA uses in-house injection molding equipment to produce plastic housings and components for charger products.
SMT & PCBA Production
PCB assembly uses pick-and-place machines, reflow soldering and AOI inspection.
Product Assembly
SUNDA assembles car chargers, wall chargers and charging cables through its in-house production operations.
Aging & Burn-in Testing
Finished electronic products undergo aging and burn-in testing before final quality inspection.
Final QC & Packaging
Products pass final quality checks before packing and preparation for shipment.
