Special Purpose Machines: Why One-Size Automation Fails

Jim Karatasos

Off-the-shelf automation has its place. For common products, stable processes and predictable production environments, standard machines can be an efficient and cost-effective solution.

However, many Australian manufacturers eventually reach a point where one-size automation no longer fits. Products evolve, volumes change, space becomes constrained and regulatory requirements tighten. At this stage, forcing a standard solution to work often introduces more complexity than it removes.

This is where Special Purpose Machines come into play — not as a luxury, but as a logical next step when standard automation reaches its limits.

The Promise and Limits of One-Size Automation

Why Standard Automation Solutions Exist

Off-the-shelf machines are designed to solve common problems efficiently. By targeting the “average” application, manufacturers of standard equipment can reduce cost, shorten lead times and simplify deployment.

For many businesses, these solutions work well — initially.

Designed for the Average, Not the Reality

The challenge is that very few manufacturing environments remain average for long. Products change, packaging formats evolve, and production demands shift. Standard machines are often slow to adapt to these changes.

When Flexibility on Paper Fails in Practice

Many standard machines claim flexibility through optional kits or adjustments. In practice, this flexibility can come at the cost of longer changeovers, reduced reliability and increased operator involvement.

What Are Special Purpose Machines?

Defining Special Purpose Machines in Manufacturing

Special Purpose Machines are purpose-built automation systems designed specifically around a manufacturer’s product, process and constraints. Rather than adapting the process to fit the machine, the machine is designed to fit the process.

Purpose-Built Automation vs Configurable Standard Equipment

While configurable machines attempt to cover a wide range of applications, special purpose machines focus on doing one job — or a defined set of jobs — exceptionally well.

This focus often results in higher reliability, better performance and lower long-term operational risk.

Where Special Purpose Machines Fit in an Automation Strategy

Special purpose machines are most valuable where:

•  Processes are unique or non-standard
•  Tolerances, speeds or accuracy are critical
•  Manual intervention is creating risk or inefficiency

Why One-Size Automation Often Breaks Down

Products, Processes and Constraints Are Rarely Standard

Real manufacturing environments are full of constraints: limited floor space, variable product quality, upstream inconsistencies and regulatory requirements. Standard automation often struggles to handle these realities without compromise.

Compromises in Speed, Accuracy and Reliability

To make a standard machine work, manufacturers may accept slower speeds, reduced accuracy or additional manual checks. Over time, these compromises erode the original value proposition.

The Hidden Cost of Workarounds and Manual Intervention

Workarounds are rarely free. They introduce labour dependency, increase training requirements and create opportunities for error — all of which undermine automation’s purpose.

Common Signs That Standard Automation Is No Longer Fit for Purpose

Increasing Operator Dependence

If a supposedly automated process requires constant operator input to keep it running, it may no longer be fit for purpose.

Frequent Adjustments, Tweaks and Overrides

Regular adjustments, software overrides or mechanical tweaks often indicate that the machine is operating outside its intended application.

Declining Uptime and Growing Complexity

As workarounds accumulate, systems become harder to maintain and troubleshoot. Downtime increases, and reliability suffers.

The Real Cost of Forcing a Process to Fit a Machine

Lost Efficiency and Underutilised Equipment

Machines that never quite run as intended often operate below their rated capacity. This results in underutilised assets and reduced return on investment.

Quality Risks and Inconsistent Output

Inconsistent processes lead to inconsistent quality. Manual intervention and variability increase the risk of defects, rework and customer complaints.

Long-Term Maintenance and Support Challenges

Non-standard modifications to standard machines can make long-term support difficult, particularly if OEM support no longer aligns with how the equipment is being used.

Where Special Purpose Machines Deliver the Most Value

Unique Products and Non-Standard Formats

Products that fall outside common size, shape or handling norms are often poor candidates for off-the-shelf automation.

Tight Space, Speed or Accuracy Requirements

When floor space is limited or precision is critical, purpose-built machines allow designs to be optimised around real constraints.

Hazardous, Regulated or High-Risk Environments

In regulated or hazardous environments, special purpose machines can be designed to meet safety and compliance requirements without compromise.

Special Purpose Machines as a Strategic Manufacturing Capability

Solving Problems Standard Automation Cannot

Special purpose machines address challenges that standard solutions simply are not designed to solve. This capability becomes a competitive advantage.

Reducing Operational Risk Through Purpose-Built Design

By eliminating unnecessary complexity and manual intervention, bespoke machines often reduce long-term operational risk.

Creating Competitive Advantage Through Capability

Manufacturers with unique automation capabilities are harder to replicate and better positioned to adapt to market changes.

Addressing the Perceived Risks of Bespoke Automation

Capital Investment and ROI Concerns

Bespoke automation is often perceived as higher risk. In reality, forcing a standard solution into an unsuitable application can be far riskier over the system’s lifecycle.

Managing Technical and Project Risk

Structured project planning, staged development and clear scope definition significantly reduce risk in special purpose machine projects.

Why Structured Design Methodology Matters

A disciplined design methodology ensures risks are identified early and addressed before they become costly problems.

Designing and Building Special Purpose Machines Successfully

Application-First Design Thinking

Successful projects start with a deep understanding of the application — not a preconceived machine concept.

Prototyping, Testing and Validation

Prototyping and real-world testing are often essential, particularly where product variability or process uncertainty exists.

Integration With Existing Equipment and Processes

Special purpose machines must integrate seamlessly with existing systems to deliver their full value.

Special Purpose Machines in the Australian Manufacturing Context

Why Local Knowledge and Experience Matter

Australian manufacturing environments have unique challenges, from compliance requirements to labour availability and site constraints.

Compliance, Safety and Australian Standards

Purpose-built automation must be designed to meet Australian safety standards and regulatory expectations from the outset.

Supporting Complex Automation Over Its Lifecycle

Long-term support is critical for complex systems. Access to local engineering expertise ensures issues are resolved quickly and effectively.

The Value of Local Design, Build and Support

Faster Problem Solving and Practical Outcomes

Local teams can respond faster, adapt designs more easily and provide practical solutions grounded in real manufacturing experience.

Avoiding Offshore Misalignment

Offshore designs can struggle to account for local standards, site realities and operational practices.

How Process Evolution Designs and Delivers Special Purpose Machines

Designing and building special purpose machines locally ensures they are tailored to Australian manufacturing needs and supported throughout their lifecycle.

Knowing When One-Size Automation Is No Longer the Right Answer

Key Questions Manufacturers Should Ask

•  Are workarounds becoming the norm?
•  Is reliability declining despite ongoing effort?
•  Is manual intervention undermining automation benefits?

When Bespoke Becomes the Lowest-Risk Option

When the cost and risk of compromise outweigh the cost of purpose-built design, special purpose machines become the logical choice.

Viewing Special Purpose Machines as an Investment in Capability

Rather than a last resort, special purpose machines should be viewed as an investment in long-term capability, resilience and competitiveness.

For many Australian manufacturers, the real risk is not choosing bespoke automation — it is persisting with one-size solutions long after they have stopped fitting.
