TRUSTED MANUFACTURING PARTNER IN MECHANICAL ENGINEERING & SUPPORTING INDUSTRIES
Established in 1970 as a family enterprise in Northern Vietnam, SASI relocated to Ho Chi Minh City in 1998 to expand production. Today, our operations span a 21.000 sqm facility dedicated to delivering reliable, high-precision products.
We specialize in OEM manufacturing—including laser cutting, stamping, pipe bending, welding, ED coating, and powder coating lines that deliver superior surface finishing.
Certified under IATF 16949:2016, SASI combines modern infrastructure with a flexible production workflow to maintain consistent quality and meet global standards for both domestic and international partners
Surface treatment & coating: Fully automated surface chemical pretreatment, electrophoretic coating (ED/E-coating), and powder coating.
Assembly & packaging: Support for assembling sub-assemblies and packaging according to export standards.
The in-house manufacturing process at SASI eliminates the risk of impact/scratch damage during intermediate transportation, shortens total production time by 20–30%, and consolidates quality responsibility at a single point of contact.
SASI’s ED and powder coating systems are invested in according to automotive industry standards with outstanding technical advantages:
Absolute Coverage (ED Coating): Electrophoretic penetration technology ensures 100% even paint adhesion to narrow gaps, open/closed pipe structures, and hidden corners that conventional spray paint cannot reach.
High corrosion resistance: The ED coating acts as a high-grade anti-corrosion primer, meeting salt spray test standards for 500 to over 1,000 hours depending on the paint system requirements.
Mechanical durability & aesthetics: Powder coating provides a variety of glossy/matte/textured surfaces, UV protection, good impact resistance, and mild chemical resistance.
Environmentally friendly: The ED paint line uses water-based paints with extremely low VOC content, meeting stringent environmental standards.
SASI applies a rigorous quality control process according to ISO 9001:2015 standards through 3 stages:
IQC (Incoming Quality Control): Checking certificates of origin (Co/Cq), thickness, surface finish of raw materials (steel, stainless steel, aluminum) and paint chemicals.
PQC (In-Process Quality Control): Measure the dimensions of each stage (cutting, bending, welding) using precision measuring equipment. Check the concentration of chemicals in the bath, the voltage of the ED paint, and the drying temperature hourly.
FQC (Finished Quality Control):
Check the geometric dimensions and welds.
Paint film thickness measurement (Coating Thickness Gauge).
Paint film adhesion test (Cross-hatch Cut Test / Grid Test).
Impact testing and salt spray resistance testing are performed periodically in the laboratory.
SISA accompanies customers at every stage of product development:
Prototype/Sample Manufacturing: We manufacture 1–5 prototype products for customers to test, check functionality, and approve the paint finish aesthetics before mass production.
Pilot run: Receive small/medium-sized shipments for customers to evaluate the market.
Mass production: Automated production lines enable SSI to maintain a production capacity of tens of thousands of products per month at the most optimal cost.
We manage production schedules based on fundamental factors:
Scale & Infrastructure: Located in the Ho Chi Minh City Automotive Mechanical Industrial Park with a large factory area, fully equipped with high-capacity machinery operating flexibly in shifts.
ERP/MES Planning System: The entire production process, from raw materials to painting and packaging, is monitored in real-time, minimizing downtime.
Proactive Material Supply: SSI maintains a stable supply chain and standard raw material inventory, enabling production to be activated immediately upon order confirmation.
