Sheet metal is widely used across numerous industries due to its versatility. It can be easily cut, shaped, welded, and assembled into both large and small components with intricate designs. Each fabrication project requires a deep understanding of good design principles. Key considerations during the design phase include material properties, available fabrication equipment, manufacturing feasibility, and cost-effectiveness. Different types of metal vary in thickness and other qualities, influencing the appropriate fabrication methods.
Designers and engineers use computer-based tools to create detailed blueprints and models that guide the rest of the fabrication process. At Metaltech, our engineers and technicians specialize in creating precise designs for new product development or improving existing ones. We troubleshoot issues and suggest enhancements to ensure the final product meets high standards. Additionally, we develop prototypes for testing purposes before moving forward with full-scale production. Another specialty at Metaltech is simplifying overly complex design concepts into efficient, cost-effective solutions.
Let’s explore the fundamental aspects of advanced product design and how it connects to subsequent fabrication steps. Understanding these processes is crucial for achieving optimal results.
### Design for Metal Fabrication
A quality design drawing is essential for accurate manufacturing specifications. Computer-aided design (CAD) drawings need to align with real-world manufacturing practices, following the principle of Design for Manufacturability (DFM). This critical step is often overlooked when considering the long-term success of a product.
At Metaltech, our experienced design engineers work closely with clients to implement the most efficient and cost-effective methods for producing parts according to customer requirements. For clients with limited engineering resources, Metaltech offers a service where a simple concept or sketch can serve as the foundation for our team to develop a manufacturable design package.
### Design Details
First and foremost, the design must clearly outline overall dimensions and product specifications. Details include material characteristics like thickness, tolerances, surface flatness, bend radius, height, width, and length of the component. The drawing should also specify hole locations and diameters, weld callouts, and any special finishing requirements.
### Simplification
A second important goal is to simplify the remaining fabrication steps for easier manufacturing. This involves removing redundant or non-essential features that don’t add value. Simplification helps reduce costs while maintaining predetermined specifications.
### Tolerances
Thirdly, tolerance refers to the precision of the design and ensures product consistency. Requirements vary depending on the project and industry. Tight tolerances require advanced equipment and skilled fabricators, which can increase production costs.
### Prototypes & Testing
Fourth, Metaltech uses advanced design to create prototypes for testing and refinement. Prototype testing ensures the final product functions as intended before full-scale production begins.
### What is CAD Technology (Computer-Aided Design) and How Is CAD Technology Used?
CAD technology revolutionizes design creation by leveraging computer systems to generate precise 2D or 3D representations of objects, structures, or products. It enables designers and engineers to create, modify, and analyze designs with accurate measurements and specifications. CAD software facilitates detailed drafting, modeling, and visualization, allowing for realistic renderings, simulations, and analyses of various factors. Its collaborative features allow multiple users to work simultaneously, streamlining teamwork and enhancing coordination. Overall, CAD improves efficiency, speeds up design processes, and minimizes errors before manufacturing stages.
### Design & Other Fabrication Processes
Design serves as a roadmap for other fabrication steps such as cutting, forming, and welding. Advanced CAD software ensures compliance with product specifications and reduces time to market.
### Materials & Thickness
The fabrication process must be tailored to the chosen material. For instance, aluminum is easier to cut than steel due to its lighter weight. Factors for selecting the right material include expected wear, vulnerability to corrosion, manufacturer specifications, aesthetic preferences, need for conductivity, and mechanical properties. Designers should collaborate with fabricators to understand the unique qualities of different metals, which will impact the manufacturing process.
The design must also specify the thickness of the metal, typically ranging from 0.5 mm to 6 mm for most projects. Thicker metals offer strength and durability, whereas thinner metals are suitable when flexibility and lightweight are necessary.
### Cutting Guidelines
When specifying holes and other cuts in sheet metal, designers must consider proper techniques. The type of metal and sheet thickness affect the appropriate hole size. Proper spacing prevents deformation and maintains structural integrity.
### Bending & Forming
The fabrication process includes bending metal into predetermined shapes by applying pressure. Advanced press brakes use specialized hydraulic functionality to shape cut metal sheets precisely. CAD designs indicate exactly where bends should occur, ensuring accurate reflections of real-world bending techniques and forming processes.
### Machining & Welding
Project designs must align with the capabilities of available welding equipment by adhering to DFM principles. Important considerations include torch accessibility, material compatibility with welding temperatures, avoiding deformation of thin materials, and ensuring sufficient thickness for successful welding.
### Finishing
Finishing is usually the final step in the fabrication process before assembling individual components. The choice of finish depends on the manufacturer's objectives, such as corrosion protection or aesthetic enhancement. Common finishes include anodizing, brushing, polishing, tumbling, bead blasting, powder coating, plating, passivation, and chrome coating. These can be categorized as either protective or aesthetic.
