Design

Design is the foundation of a successful manufactured part. Our design process focuses on translating functional requirements into producible components through accurate modeling, analysis, and manufacturability considerations. At Plummer Industries we support projects from concept through production using CAD, 3D scanning, and design-for-manufacture practices. Below is an overview of each capability and how it can support your project.

Computer-Aided Design (CAD) is used to create accurate 3D models and detailed drawings that define part geometry, dimensions, and critical features. These models serve as the basis for manufacturing, inspection, and assembly.

• Parametric Modeling – Designs are built with adjustable dimensions and features, allowing efficient iteration and refinement.
• Detailed Drawings – Production-ready drawings include tolerances, notes, and references required for manufacturing and inspection.
• Assembly Design – Multi-part assemblies are modeled to verify fit, function, and interaction between components.
• Revision Control – Design changes are tracked to ensure the correct version is used throughout production.

3D Scanning captures the geometry of existing parts or assemblies and converts them into accurate digital models. This process is ideal for reverse engineering, fit verification, and updating legacy components.

• Reverse Engineering – Physical parts can be converted into editable CAD models when drawings or files are unavailable.
• Fit & Clearance Verification – Scanned data helps confirm how new components will interface with existing parts or assemblies.
• Legacy Part Support – Older or worn components can be digitized and redesigned for improved performance or manufacturability.
• Rapid Data Capture – Complex geometry can be captured quickly without manual measurement.

Design for Manufacture (DFM) focuses on optimizing designs so they can be produced efficiently, accurately, and cost-effectively. DFM considerations are incorporated early in the design process to reduce risk and improve production outcomes.

• Process-Aware Design – Parts are designed with machining, welding, and fabrication constraints in mind from the start.
• Tolerance Optimization – Tolerances are applied only where needed, reducing manufacturing complexity and cost.
• Material Selection – Materials are chosen to balance strength, performance, availability, and machinability.
• Cost & Lead-Time Reduction – Early design adjustments help minimize secondary operations, setups, and rework.

3D Printing, also known as additive manufacturing, is a process that builds parts layer by layer directly from a digital model. This approach enables rapid creation of complex geometries, internal features, and low-volume parts without the need for tooling.

• Rapid Prototyping – Parts can be produced quickly for fit checks, functional testing, and design validation before committing to production processes.
• Complex Geometry – Additive manufacturing allows internal passages, organic shapes, and features that are difficult or impossible to machine conventionally.
• Design Iteration – Digital models can be updated and reprinted efficiently, supporting fast design changes and refinement.
• Functional Parts – Printed components can be used for fixtures, jigs, housings, and low-load end-use applications.
• Manufacturing Support – 3D printing is often used to support other processes by producing custom tooling, fixtures, and assembly aids.
