Premium Anodized Aluminum Shells with Custom Profiles

Custom Aluminum Extrusion Solutions for Precision Industrial Applications

At Sunhang, we specialize in delivering high-performance aluminum fabrication services tailored to meet the exacting demands of global engineering and manufacturing industries. Whether you're seeking standard public mold products or fully customized extruded aluminum profiles, our comprehensive capabilities ensure precision, durability, and efficiency across every project. With over a decade of experience in producing electric motor housings, engine casings, and CNC-machined components, we provide end-to-end solutions that combine advanced material science with meticulous craftsmanship.

Our core offerings include custom aluminum extrusions, precision-engineered motor enclosures, and durable engine covers designed for industrial machinery, automation systems, and electric vehicle applications. Each product is manufactured using state-of-the-art techniques such as CNC machining, laser cutting, wire EDM, and punching—ensuring dimensional accuracy within tight tolerances. We support multiple file formats including STEP (STP), IGES (IGS), DWG, DXF, PDF, AI, CDR, and even accept physical samples for reverse engineering, making collaboration seamless regardless of your design format.

Key features of our aluminum fabrication process include customizable hole drilling methods—such as punch, CNC, laser, or wire cut—to accommodate specific electronic component requirements. Surface treatments like sandblasting, brushing, anodizing, powder coating, painting, and electrophoresis allow for both aesthetic customization and enhanced corrosion resistance. Common color options include black, silver, iron gray, blue, and gold—anodized finishes that offer long-lasting protection while maintaining structural integrity under demanding conditions.

The production timeline varies based on complexity: stamping dies typically take 7–10 working days, small profile extrusion dies require 10–12 working days, and large profile dies may need up to 25 working days. For customers without existing drawings, our team provides expert consultation and develops multiple design alternatives tailored to your application needs. This flexibility ensures that whether you have detailed CAD files or just a sample part, we can translate your vision into a functional, manufacturable solution.

These aluminum extrusion parts are ideal for use in electric motors, gearboxes, control panels, heat sinks, and mechanical assemblies where lightweight yet robust materials are essential. The inclusion of Corner code connectors facilitates quick and secure assembly, reducing downtime during installation. Our precision-engineered components are widely used in sectors such as renewable energy, robotics, medical equipment, and automotive manufacturing—where reliability, thermal performance, and compliance with international standards are non-negotiable.

Customers consistently praise our attention to detail, consistent quality, and ability to deliver complex designs on time. Many appreciate how our engineers bridge the gap between conceptual ideas and production-ready prototypes, especially when working with unfamiliar geometries or tight lead times. By combining technical expertise with responsive communication, we build lasting partnerships grounded in trust and innovation.

Common questions often revolve around surface finish options, lead time variability depending on die complexity, and compatibility with various mounting configurations. We recommend specifying your preferred finish early in the design phase to avoid delays, and for intricate projects, we encourage early engagement with our design team to optimize manufacturability and cost-effectiveness. With flexible customization, rapid prototyping, and globally compliant manufacturing practices, Sunhang remains a trusted partner for companies seeking precision aluminum solutions worldwide.
