Import Gravity Casting — Buy in Bulk from Supplier in China

Eastcasting Co., Ltd manufactures gravity‑cast components using aluminium alloy A356 (G‑AlSi7Mg) and zinc alloy. The process accommodates a minimum thickness of 2 mm and can achieve a surface roughness as low as Ra 3.2 µm. Dimensional precision is classified as CT5‑CT7 for aluminium and CT3‑CT6 for zinc, matching the supplier’s stated tolerances. Individual castings may weigh up to 60 kg and the largest workable area measures 1000 cm × 700 cm.

Typical aluminium gravity casts exhibit tensile strengths around 250 MPa and hardness of 95 HB, which aligns with industry expectations for A356 alloy. Standard post‑casting treatments include sandblasting, vibration, polishing, anodising, plating and powder‑coat finishes, allowing buyers to select surface properties that suit end‑use requirements. The alloys’ density of approximately 2.68 g/cm³ (aluminium) and 7.0 g/cm³ (zinc) influence tooling load and mould design. These characteristics are common across foundries producing automotive and mechanical parts.

The castings are employed in automobiles, motorcycles, outboard engines, electrical and communications equipment, as well as hardware tools. Eastcasting offers bulk packaging and can arrange shipment from Ningbo port, but buyers should confirm minimum order quantities, incoterms and payment terms directly with the supplier. The supplier’s response rate is currently zero, so trade inquiries may require follow‑up through the platform’s messaging system. Verification of material certificates and dimensional inspection reports is recommended before finalising any contract.

Eastcasting Co., Ltd is located at No.107 Xiaowen Street, Ningbo 305010, Zhejiang, China. The company operates as an imported‑tier supplier and holds a harbour trust tier within the platform’s verification system. Its profile shows a response rate of 0 % and no recorded average response time, indicating that communication may be limited without proactive outreach. The factory hosts three dedicated gravity‑casting production lines equipped with a range of casting machines.

The listed capabilities focus on aluminium and zinc alloys, with in‑house chemical analysis and mechanical testing instruments to verify material properties. Eastcasting provides a suite of finishing options after casting and handles packing and shipping directly from its Ningbo facility. No additional certifications, MOQ or lead‑time details are disclosed, so buyers should request these specifics before placing an order.
