Trusted by Australia’s Leading Manufacturers
MEX Engineering Group provides embedded site teams and engineering services to some of the country’s largest production facilities. We maintain critical infrastructure for industry leaders across FMCG, food and beverage, and high-speed packaging, including Tooheys, CHEP, Ullrich Aluminium, Goodman Fielder, and BlueScope Steel.
From Engineering Design to Boots-on-the-Ground Execution
We eliminate contractor inconsistency by managing the entire lifecycle of your infrastructure. Our process begins with detailed CAD-based mechanical design and control system architecture.
We then deploy our in-house tradespeople to execute the installation, ensuring that the engineering strategy is perfectly translated into practical, on-site reality. We secure this investment by providing comprehensive as-built drawings and ongoing fractional maintenance coverage.
How we saved $17,000 per hour by reducing downtime
Our client’s plastic pallet washing facility is a critical piece of their supply chain infrastructure that runs 24/7. MEX Engineering Group was engaged to provide 24-hour operational assistance and weekend preventative maintenance shifts.
By embedding a team of three maintenance electricians and one mechanical fitter, we organise all trades, source parts, and schedule repairs. Since taking control of the site, downtime has decreased significantly. With client downtime valued at approximately $17,000 per hour, our engineered maintenance strategy delivers considerable, measurable savings across their business operations.
Reliable Safe Design Integration Framework
We follow a structured design methodology to ensure that machinery and systems are developed to achieve strict regulatory compliance.
Defining Safety Requirements
Establishing clear specifications based on the risk assessment, operational considerations, and AS/NZS standards.
Allocation of Safety Controls
Linking each identified hazard with the appropriate engineering control measure.
Selection of Safety Components
Specifying certified safety devices that support the required Performance Level (PL) or Safety Integrity Level (SIL).
Design Review & Validation Planning
Incorporating structured reviews to confirm the safety measures will perform as intended.
Turnkey Implementation
Managing the fabrication, installation, programming, and commissioning in-house to minimise production disruption.
Verification
Conducting detailed analysis and functional checks to confirm installed safety measures reduce identified risks to an acceptable level.
What Our Clients Are Saying
We would highly recommend MEX Engineering Group to any business looking to improve equipment reliability, product quality, and operational performance. Their response time is fantastic for breakdown support 24 hour 7 days a week.

Adapting to Strict Compliance and Audit Demands
Many engineering firms bundle safety hardware sales with their engineering services, leading to hardware bias and inflexible designs. As SafeWork enforcement increases across Australian manufacturing, relying on legacy unguarded plant or “bundled” safety fixes exposes your operations to compliance risks and downtime. Engaging our OEM-agnostic CMSE® professionals ensures your safety design is strictly tailored to your plant’s reality, acting as robust protection against audit failure and incident exposure.

Frequently Asked Questions
What is Safety Concept Development?
Safety Concept Development moves beyond simply identifying risks in an audit. It is the process of translating identified hazards into practical, engineered safety architectures—such as safety-PLC integration and custom interlocked guarding—ensuring your machinery meets AS/NZS standards while maintaining optimal productivity.
Why is an OEM-Agnostic approach important for safety design?
Many safety consultants are tied to specific hardware manufacturers, which can lead to inflexible designs or unnecessary “bundling” costs. An OEM-agnostic approach means we recommend and specify certified safety components based purely on what is best for your machinery, processes, and existing infrastructure, eliminating hardware bias.
What is Performance Level Determination (PLr)?
Performance Level Determination is the process of identifying and specifying the required safety performance levels for each critical safety function. This ensures that the engineered safety controls we design provide the exact level of risk reduction required to comply with applicable standards like AS/NZS 4024.
Why is system integration critical for modern manufacturing?
System integration connects isolated machinery, electrical controls, and data communications into a single, cohesive line. This prevents operational bottlenecks, reduces manual handling errors, and ensures that mechanical and electrical components operate in perfect synchronisation to maximise throughput.
Do you provide 24/7 breakdown support for your engineered systems?
Yes. MEX Engineering Group operates a true 24 hour, 7 day breakdown response service. We do not just design and install; we provide the ongoing fractional maintenance and rapid recovery capability required to protect your uptime.
Are your engineering services compliant with Australian Standards?
Absolutely. We operate under rigorous HSEQ frameworks, and international certifications. Our engineering designs and machine safety audits strictly adhere to AS/NZS 3000 wiring rules and are supported by in-house CMSE® – Certified Machinery Safety Expert (TÜV NORD).
Do you use subcontractors for your mechanical and electrical engineering?
Our core capability is delivered by our own highly trained, full-time technicians and engineers, eliminating contractor handoff risk. We invest heavily in our dedicated in-house training centre to ensure every staff member meets the MEX Engineering Group standard of excellence before stepping onto your site.
