Mechanical and Industrial Design Services Enclosures, Thermal, and DFM

Qmax Systems provides mechanical and industrial design services - enclosures, thermal paths, and load-bearing structures engineered alongside the PCB from the schematic stage. Optimized for DFM and DFA from day one, Qmax Systems delivers certification-ready hardware for high-stakes electronics, from MIL-STD-810 tactical devices to thermally-dense power electronics.

Overview

Qmax Systems delivers mechanical and industrial design services for high-stakes electronics, where a product is more than a functional PCB - it is a physical entity that must survive its environment, satisfy ergonomics demands, and meet stringent regulatory requirements. These services move beyond generic CAD modeling to fully integrate hardware, thermal physics, and manufacturing realities.

Whether you are developing a ruggedized MIL-STD-810 tactical device, a high-density power inverter, or a sleek IoT wearable, our team bridges the gap between electrical engineering and mechanical execution. We focus on the critical intersection of PCB mechanical integration, thermal management, and structural integrity to ensure your product is reliable, manufacturable, and aesthetically aligned with your brand identity.

By involving our mechanical and industrial designers at the schematic stage, we eliminate the common "design-over-the-wall" friction. We optimize for DFM (Design for Manufacturing) and DFA (Design for Assembly) from day one, reducing iteration cycles and ensuring that your enclosure is not just a box, but a high-performance component of your overall system.

Mechanical & Industrial Design Capabilities

Physics-driven mechanical design that predicts how your electronics behave under stress, vibration, and extreme temperatures.

Qmax Systems roots its mechanical design in physics, not rules of thumb. Finite Element Analysis (FEA) and Thermal Analysis predict how your electronics behave under stress, vibration, and extreme temperatures.

Structural & Environmental

  • Enclosure Design - Qmax designs enclosures in plastic injection molding, machined aluminum, and sheet-metal fabrication.
  • Ruggedization - Qmax's engineers design for shock, vibration, and impact resistance to MIL-STD and JSS standards.
  • Environmental Protection - Sealing designs meet IP65, IP67, and IP68 ratings.

Thermal & Mechanisms

  • Thermal Management - Qmax delivers active and passive cooling, including custom heat sinks and airflow optimization.
  • Kinematic Design - Kinematic design controls precise movement for hinges, sliders, and latching mechanisms.

Frequently Asked Questions

How do you manage heat dissipation in sealed IP67 enclosures?
We utilize thermal simulation (CFD) to design internal heat spreaders and utilize the enclosure's external surface area as a heat sink, often employing thermally conductive plastics or metal chassis.
Can you design for MIL-STD-810G vibration and shock requirements?
Yes. We perform FEA-based vibration analysis to identify resonance points and implement ruggedized mounting features or potting compounds where necessary.
What is the difference between DFM and DFA in your process?
DFM (Design for Manufacturing) focuses on the ease of fabricating individual parts (e.g., injection molding), while DFA (Design for Assembly) focuses on reducing part count and simplifying the manual or automated assembly of the final product.
Do you support PCB thermal profiling?
Absolutely. We analyze component-level heat loads on the PCB to design optimized cooling paths, whether through forced air, heat pipes, or thermal interface materials (TIM).
How do you ensure the mechanical design doesn't interfere with RF performance?
We work closely with RF engineers to select non-interfering materials and design shielding cans or antenna clearances that maintain signal integrity.
What prototyping methods do you use for functional testing?
Depending on the requirement, we use CNC machining for strength, SLA/SLS for high-detail fitment, or vacuum casting for bridge production.
Can you help with CMF (Color, Material, Finish) specifications?
Yes, we provide detailed CMF documents that specify Pantone/RAL colors, texture grades (VDI/MT), and coating types (powder coating, anodizing, etc.).
Do you design for intrinsically safe (IS) environments?
Yes, we understand the mechanical constraints required for ATEX/IECEx certification, including creepage, clearance, and impact resistance.
How do you handle tolerance stack-up analysis?
We perform worst-case and RSS (Root Sum Squared) tolerance analysis to ensure that parts fit together perfectly across high-volume production runs.
At what stage should I start mechanical design?
Ideally, at the block diagram stage. Early mechanical involvement ensures that the PCB shape and component placement are optimized for the final enclosure size and thermal requirements.
