MAIN PRODUCTS

High-accuracy CNC machining for custom metal/plastic parts, serving aerospace, automotive, electronics, and medical industries. Automated programming ensures ±0.01mm precision, batch consistency, and scalable solutions from prototyping to mass production.

CNC Machining

High-pressure die casting for complex metal parts (aluminum, zinc, magnesium alloys), serving automotive, electronics, and industrial sectors. Delivers smooth finishes, tight tolerances (±0.1mm), rapid cycles, and scalable solutions from prototyping to mass production. ISO-certified quality with cost-effective, high-volume manufacturing.

Die Casting

Custom aluminum/plastic profile extrusion for construction, automotive, industrial, and consumer sectors. Delivers complex cross-sections, high-precision tooling, surface treatments, and consistent quality (±0.2mm). Supports prototyping to mass production with fast cycles, cost-efficiency, and ISO-certified manufacturing.

Extrusion

Complex metal parts (stainless steel, aluminum, high-temperature alloys) for aerospace, medical, and automotive industries. Delivers thin walls, tight tolerances (±0.2mm), and smooth surfaces. Supports prototyping to mass production with fast cycles, cost-efficiency, and ISO-certified quality.

Investment Casting

Custom stainless steel, aluminum, and carbon steel parts for electronics, construction, automotive, and industrial sectors. Delivers precise cutting, bending, forming, and surface treatments. Supports prototyping to mass production with tight tolerances (±0.3mm), fast turnaround, and ISO-certified quality.

Sheet Metal Fabrication

Custom metal/plastic treatments (anodizing, plating, coating) for automotive, aerospace, medical, and consumer industries. Ensures corrosion resistance, aesthetic appeal, and durability. Supports prototyping to mass production with fast turnaround, eco-friendly processes, and ISO-certified quality standards.
