Mechanical Engineering Services

Our mechanical engineering services address the complete lifecycle of a product, from material selection and mechanism design to system  prototyping and testing. We focus on creating functional and manufacturable designs that meet your specific requirements. The discipline of mechanical product design demands a deep understanding of physics, materials science, and manufacturing processes. Our team applies this knowledge to develop robust products that perform reliably under their intended operating conditions.

We offer extensive design services, ranging from basic enclosures to intricate electromechanical systems. By incorporating analysis and simulation early in the design process, we detect potential problems early and enhance the mechanics for better performance and longevity. Our mechanical engineering services ensure that organizations can confidently progress from initial concept to a fully developed, market-ready product.

Enclosure Design

We design a wide range of enclosures from complex electronics enclosures to large equipment enclosures to low-cost injection molded enclosures.

• Environmental resistance
• Ingress protection
• Seal design
• Latching mechanisms
• Thermal management / heat rejection

Electronics Packaging

• Electronics enclosures
• PCB mounting
• User Interface (UI) design

Ruggedization

We frequently optimize the durability and reliability of hardware in harsh conditions. We design for:

• Temperature resistance
• Chemical resistance
• Corrosion resistance

• Vibration, impact, and shock resistance
• Ingress protection
• MIL-STD-810G

Machine Design

Machine design is a subset of mechanical engineering and an area of expertise at SGW. We apply this expertise to a wide range of products, from consumer to industrial, when mechanics need to be optimized.

Mechanisms

• Latching
• Clamping
• Lifting

• Rotating
• Positioning
• Actuation

Power Transmission

• Mechanical (gear drives, chain drives, belt drives, rack and pinion, etc.)
• Hydraulic
• Pneumatic
• Conveyance

Fixturing and Tooling

• Manufacturing equipment
• Robotic end of arm tooling (EOAT)
• Test fixtures and jigs
• Assembly fixtures and jigs

Electromechanical Systems

Many products incorporate coordinating mechanical and electrical systems. Also referred to as mechatronics, these electromechanical designs leverage multiple disciplines. In development, parallel efforts need to be managed carefully to ensure designs converge to a viable, unified solution.

For products centered on electromechanical design, we often leverage these disciplines:

• Industrial
• UI/UX Design
• Electronics and Embedded Systems

Engineering Analysis

We apply engineering analysis through traditional and advanced computational techniques. Common analysis subjects include:

• Loads and stresses
• Heat transfer and thermodynamics
• Fluid mechanics

Simulation techniques such as Finite Element Analysis (FEA) are commonly used and often paired with experimental techniques for effective analysis.

Materials and processes we commonly design for

• Injection molded plastic
• Overmolding
• Rotomolded plastic
• 3D printing
• Machined components
• Sheet metal (bent, laser-cut, die-cut, welded)

• Stock metal cross-sections and weldments (plate, tube, channel, angle, etc.)
• Aluminum extrusion
• Die-casting
• Off-the-shelf components
• Various rubber sealing components
• Various coatings and paints
