Import Aluminum Die Casting — Buy in Bulk from Supplier in China

Ningbo Musun Metaltronics Ltd. produces aluminum die casting components from its facility in Ningbo, Zhejiang Province, using pressure die casting methods suited to complex geometries. The source material indicates these parts are cast from aluminum alloys with a lightweight structure and corrosion-resistant properties, offered with optional anodized or painted surface treatments. Typical alloy grades for this product category include ADC12, A380, and A360, though buyers should confirm the exact alloy specification with the supplier. The die casting process employed allows thin-wall construction and intricate detail replication, with typical dimensional tolerances ranging from plus or minus 0.05mm to plus or minus 0.5mm depending on part size and complexity.

Standard material grades for aluminum die casting in China follow GB/T standards, with ADC12 representing a common Al-Si-Cu alloy containing 9.6 to 12.0 percent silicon and 1.5 to 3.5 percent copper. Heat treatment options typically include T4, T5, and T6 tempers, affecting tensile strength and elongation characteristics. Surface finishes beyond anodizing and painting may include shot blasting, vibration finishing, or chromate conversion coating, depending on application requirements. The source description notes custom design and size accommodation, suggesting toolmaking capability for bespoke projects. Porosity control, critical for pressure-tight applications, is typically managed through vacuum-assisted die casting or porosity-sealing processes, though specific methods should be confirmed directly.

Primary applications span automotive components, electronic housings, and general machinery manufacturing. Buyers in these sectors typically require batch consistency, traceable material certifications, and dimensional reporting. The supplier states compliance with ISO standards, though specific certificates and their scope should be verified before order commitment. Packaging, shipping terms, and minimum order quantities are not specified in the source data and require direct negotiation. Lead times for custom die casting tooling generally range from four to eight weeks in this industry, with production batches following sample approval.

Ningbo Musun Metaltronics Ltd. is located at No.54 Dashani Street, Ningbo, Zhejiang Province, postal code 315000. The company holds an imported supplier tier classification and a harbor trust tier rating. The response rate is recorded at 0.00 percent, with average response hours at zero, indicating no response data is available through this channel. These signals suggest buyers should initiate contact through multiple methods and allow adequate time for supplier engagement.

The supplier's profile through this listing focuses on aluminum die casting with custom design capability, though no employee count, annual revenue, factory size, or client references are stated. No specific certifications beyond general ISO mention are detailed in the source material. Buyers should request current ISO 9001 or IATF 16949 certificates if automotive supply is intended, along with any relevant material test reports and dimensional inspection records. The Ningbo location provides access to Ningbo-Zhoushan Port, one of China's busiest container ports, which may offer logistical advantages for export shipments.
