Zhejiang Dongrun Casting Industry Co., Ltd Alu
Zhejiang Dongrun Casting Industry Co., Ltd Alu is a Chinese casting manufacturer with a long-standing presence in the metal casting sector. Founded in 1995 and located in Yongkang, Zhejiang, the company positions itself as a reliable supplier across multiple casting technologies, aiming to meet varied production requirements for its clients. The organization emphasizes a multi-process approach that covers several stages of manufacturing from raw casting to finished parts.
Casting capabilities: The company provides four major casting processes to address different design and production needs. These include sand casting, gravity casting, die casting, and low pressure die casting. Each process has its own set of design considerations, tolerances, and surface finishes, enabling customers to choose the most appropriate method for their part geometry, material, and production volume. By offering diverse casting options, the firm can accommodate a broad range of applications and material families commonly used in industrial components, automotive parts, and machinery.
In-house machining: Beyond casting, Zhejiang Dongrun Casting Industry Co., Ltd Alu maintains a CNC machining workshop equipped with four-axis machining capabilities. This integrated approach allows the company to perform critical secondary operations in-house, such as milling, drilling, and contouring, which helps reduce lead times and improve process control for complex components. The presence of a four-axis CNC setup supports higher precision and better surface finish requirements for machined features that accompany cast parts.
Finishing and surface treatment: The company also offers a suite of finishing processes to further enhance the performance and aesthetics of cast parts. Finishing options mentioned include polishing and mirror polishing, as well as mechanical surface treatments like sand blasting. These finishing steps are commonly used to achieve defined surface textures, improve tolerance consistency, and prepare parts for subsequent coatings or assembly.
Coatings, plating, and surface protection: A range of post-casting surface treatments are available to meet corrosion resistance, wear resistance, and appearance requirements. The listed capabilities include heat treatment for mechanical property adjustments, painting for decorative or protective purposes, and powder coating for durable surface protection. Additional surface enhancement options include anodizing, electroplating, and chrome plating, which can contribute to improved corrosion resistance and surface hardness for suitable alloy systems.
Quality and reliability considerations: While the specific quality assurance measures are not detailed in the available materials, the combination of multiple casting processes, in-house CNC machining, and a broad finishing suite suggests a workflow oriented toward producing finished parts suitable for integration into larger assemblies. Customers seeking components that require precision machining and reliable surface treatments may benefit from the integrated services offered by this organization.
Applications and markets: The company’s capability set aligns with industries that routinely require metal components with precise dimensions and robust surface finishes. These could include automotive, machinery, industrial equipment, and consumer electronics applications that demand both casting and post-casting processing in a single supply chain. The breadth of processes available indicates potential for development of turnkey solutions, from component procurement through to finished parts ready for assembly.
Development potential and collaboration: For clients with specific production needs, the presence of both casting versatility and machining capability provides a platform for custom tooling, design iterations, and process optimization. Engagement opportunities may include material selection guidance, casting process optimization, tolerance control, and surface treatment customization to meet endurance, appearance, or regulatory requirements.
Summary: Zhejiang Dongrun Casting Industry Co., Ltd Alu represents a multi-process metal fabrication partner with established experience dating back to 1995. Its four main casting methods, combined with an in-house four-axis CNC machining workshop and a comprehensive finishing and coating suite, enable it to deliver integrated components from raw castings to finished parts. While the available information emphasizes manufacturing capability, potential customers should engage directly with the company to obtain detailed specifications, quality certifications, production capacity data, and lead-time information tailored to their project needs.
