5 Signs Your Material Handling Process Is Driving Up Factory Costs

In industrial manufacturing, material handling is an indispensable part, from lifting and moving to positioning raw materials, semi-finished products, and finished products. However, if this process is not optimized, businesses may be bearing many hidden costs that are not easy to recognize.

Injuries from manual handling, machine idle time, damaged materials, unstable productivity, or excessive reliance on manual labor can all increase costs and directly affect production efficiency.

So how do you recognize if your material handling process is causing waste? Below are 5 common signs businesses should check and solutions to help optimize material flow, increase productivity, and control costs more effectively.

What is material handling? Why does it directly affect production costs?

What is material handling?

Material Handling involves all activities related to lifting, lowering, moving, positioning, storing, and protecting raw materials, semi-finished products, and finished products within the factory. Although it does not directly change the value of the product, this is an important link that helps the material flow operate continuously between production stages.

In reality, a material handling process can include many familiar operations such as feeding workpieces to processing machines, removing products from the assembly line, moving raw materials between areas, or lifting materials into assembly positions.

Why does material handling affect production costs?

When the material handling process is not optimized, costs do not only come from labor or equipment but also arise in the form of waiting time, damaged materials, reduced productivity, and costs related to occupational safety. Notably, these expenses are often dispersed and difficult to identify if businesses only look at direct operating costs.

Conversely, a suitable material handling system helps maintain a stable production flow, reduces unnecessary operations, and minimizes losses incurred during lifting and moving. Therefore, optimizing Material Handling is not just a matter of transporting materials but also an important part of the strategy to control costs and improve production efficiency.

5 signs that the material handling process is causing losses

A poorly optimized material handling process is not always reflected by a clear cost. Losses can stem from workers' health, machine waiting time, damaged materials, and redundant operations in production. Below are 5 common signs that businesses should note.

Injuries, fatigue, and musculoskeletal disorders

If workers frequently have to lift, pull, push, or hold heavy objects manually, this is the first sign that the material handling process needs to be reviewed.

Repetitive movements, improper working postures, or having to handle heavy loads can cause physical fatigue and increase the risk of musculoskeletal disorders (MSDs). According to many scientific reports, MSDs account for about 30% of recorded workplace injuries and can cause workers to take days off to recover.

Not only affecting workers, these issues also entail medical costs, compensation, training substitute personnel, and production disruptions. In the long run, fatigue can also cause material handling speeds to gradually decrease during each shift.

Increased Cycle Time and the appearance of bottlenecks

Another sign is prolonged or unstable Cycle Time. When materials are not delivered to the right place at the right time, subsequent stages may have to wait, creating bottlenecks in the line.

For example, just a few seconds slower in each lifting cycle can translate into hours of lost production if this operation is repeated thousands of times in a shift. Especially when machines have high capacity but feeding is still done manually, the material handling speed can become the limiting factor for the entire line.

In addition to waiting time, handling heavily dependent on human power also creates uneven feeding speeds. This makes production planning unstable, order completion times prone to fluctuation, and increases the risk of unplanned downtime.

Labor dependency and high turnover rate

If a business constantly has to recruit people for positions involving loading, lifting, or moving heavy materials, this may be a sign that the process is overly dependent on manual labor.

Jobs with high physical demands are often difficult to sustain over a long period. When staff quit, the business not only loses an operator but also incurs additional recruitment and training costs, as well as the time it takes for new staff to get accustomed to the process.

More notably, experienced staff often possess "process knowledge" that is difficult to transfer completely through documentation. When they leave, the business may lose experience in handling situations, coordinating with the assembly line, and material handling skills accumulated over a long time.

Product damage and material loss

Materials being scratched, dented, deformed, dropped, or lost during lifting is another clear sign of an unsuitable material handling process.

For materials with high surface requirements or fragile products, using inappropriate lifting methods can generate scrap and rework costs. Especially when a part has gone through many processing stages, the damage lies not only in the value of the raw materials but also includes the machine time, energy, and labor invested in that product.

For powder, granular materials, or easily lost raw materials, manual transfer and transportation operations can also cause spills, generate dust, and increase cleaning and maintenance costs. In some specific industries, materials exposed to an uncontrolled environment can also affect the quality and stability of the product.

Human errors and the 7 types of Muda waste

When operators have to spend too much effort lifting, holding, or moving materials, concentration on main operations can decline. Consequently, the risk of misplacement, feeding the wrong material, damaging products, or performing incorrect operations also increases.

From a Lean Manufacturing perspective, these issues directly relate to forms of waste (Muda), especially:

• Motion Waste: unnecessary walking, bending, reaching, or turning.
• Transport Waste: moving materials over unnecessary distances.
• Waiting: machines or personnel having to wait for materials to be supplied.
• Inventory: maintaining a large amount of material to compensate for an unstable transportation process.
• Defects: products damaged or deviated during lifting and moving.

Many studies have shown that inefficient material handling can contribute to 5 out of 7 groups of Muda waste, while also being related to Mura (unevenness) and Muri (overburden).

Thus, if a business notices one or more of the above signs occurring frequently, the problem may not lie solely with the operator but in the very design of the material handling process. This is the time for businesses to re-evaluate the material flow, lifting methods, and the suitability of the equipment being used.

Root causes of high material handling costs

High material handling costs are usually not the result of a single factor. Behind expenses such as labor, waiting time, damaged materials, or equipment maintenance often lie systemic issues in how the factory organizes its material flow.

Suboptimal plant layout

Plant Layout directly affects the distance and frequency of material movement in the factory. When the warehouse, processing machines, assembly, and packaging areas are not arranged logically, materials may have to travel long distances or cross traffic routes multiple times.

This increases transportation time, equipment and labor utilization rates, and creates additional risks of collisions or congestion during production. Therefore, redesigning the layout based on flow simulation can help significantly reduce internal transportation costs.

Material handling process heavily dependent on manual operations

When lifting, moving, and positioning operations still rely mainly on human power, productivity is hard to maintain steadily, especially for tasks with heavy loads or high repetition frequency.

Not only does it increase manpower requirements, manual methods also entail the risk of fatigue, injury, operational errors, and material damage. Therefore, the issue is not simply "how much labor is needed," but how much cost and time each material handling operation is consuming.

Fragmented equipment investment and lack of synchronization

Some factories choose equipment from various suppliers to solve individual stages. For example, a conveyor system for one area, feeding equipment for another, and an independent control system.

This approach can create problems regarding integration, coordination, and maintenance. When an incident occurs at the intersection between systems, businesses also find it difficult to determine responsibility and resolve it quickly. That is why building an overall designed and integrated solution can help reduce operational complexity compared to fragmented investments.

Focusing only on initial investment cost instead of TCO

A piece of equipment with a low purchase price is not necessarily the most economical choice in the long term. If only looking at CAPEX and ignoring Total Cost of Ownership (TCO), businesses may fail to account for costs incurred throughout the equipment's lifecycle, such as operating labor, energy, maintenance, training, downtime, and safety risks.

Therefore, when evaluating a material handling solution, businesses should ask: How much does this equipment cost? And more importantly, What is the total cost to operate the equipment throughout its lifecycle? This is the basis to help businesses more accurately evaluate the effectiveness of an investment.

Overall, high material handling costs are often the result of a combination of suboptimal layout, manual operations, unsynchronized equipment, and an investment mindset skewed towards initial costs. Therefore, to sustainably reduce costs, businesses need to approach the problem from the perspective of processes, people, equipment, and total cost of ownership, rather than just looking to cut a single expense.

Solutions to optimize material handling costs

Reducing material handling costs is not simply cutting labor or replacing one device with another. Businesses need to look at the entire Material Flow, identify areas of waste, and choose solutions suitable for their specific production.

Below are 4 referential approaches that can help businesses gradually optimize material handling costs:

1. Applying industrial manipulators for manual lifting stages

For jobs that require frequent lifting, moving, rotating, or positioning of heavy materials, an industrial manipulator is an option worth considering.

Instead of relying entirely on human power, industrial manipulators use pneumatic or electric drive systems to help balance the load, allowing operators to handle materials more gently and accurately. This technology can create a near "weightless" state, helping operators easily lift, flip, tilt, and position the load.

This solution is particularly suitable for stages with high lifting frequency, requiring precise manipulation, or needing to limit physical impact on workers. When designed appropriately for space and load capacity, industrial manipulators can also help reduce the number of workers needed for a stage and maintain a more stable work pace.

2. Automating transportation with AGVs and AMRs

For high-frequency and repetitive material transport routes, AGVs (Automated Guided Vehicles) and AMRs (Autonomous Mobile Robots) can help reduce dependence on manual transportation methods.

AGVs are suitable for factories with relatively fixed and stable transport routes. Meanwhile, AMRs are more flexible thanks to their ability to perceive the environment, avoid obstacles, and change routes when actual conditions change.

Automating transportation aims not only at reducing labor but also at helping maintain a stable material flow, limit waiting times, and reduce the risk of collisions during movement.

3. Optimizing warehouses and material flows with Lean thinking

Technology will be difficult to maximize its effectiveness if the underlying processes are not yet optimized. Therefore, businesses should combine automation with Lean Manufacturing and Lean Warehousing to eliminate non-value-added operations.

Some applicable methods include:

• JIT (Just-In-Time): delivering raw materials to the right place at the exact time needed.
• 5S: arranging the workspace scientifically, reducing search and travel time.
• ABC Analysis: arranging materials by usage frequency, bringing high-frequency groups closer to the production area.
• Flow analysis: identifying unnecessary movements, waiting, or repetitive processing points.

Lean thinking can help businesses reduce wastes related to transportation, inventory, and redundant operations, while improving material flow within the factory.

4. Proactive maintenance to limit downtime

A material handling system is only truly effective when the equipment can operate stably. Therefore, besides periodic maintenance, businesses can consider Predictive Maintenance for critical systems.

Through sensors and operational data, businesses can monitor parameters such as vibration, temperature, pressure, or mechanical status to detect abnormal signs before the equipment suffers a serious failure.

This approach helps reduce the risk of unplanned downtime and prevents the line from having to stop just because a single piece of material handling equipment fails.

Optimizing right at the point of waste

Not every factory needs to implement comprehensive automation. In many cases, optimizing a lifting stage that is overburdening workers or creating a bottleneck can already bring clear results.

Businesses should start by evaluating loads, operational frequencies, cycle times, manpower quantities, damage rates, and costs incurred at each stage. From there, choose appropriate solutions instead of spreading investments thinly.

For problems involving lifting, moving, rotating, and positioning loads in the factory, Vietmani industrial manipulators can be one of the solutions to help businesses reduce physical labor, improve operational stability, and optimize material flow.

Vietmani industrial manipulators – the optimal solution for lifting operations

In many factories, lifting, moving, rotating, and positioning materials still depend heavily on manual labor. When the load is large or the operation is continuously repeated, this can become a point causing fatigue, reducing productivity, and generating hidden costs.

Vietmani industrial manipulators are developed to assist operators in handling loads more gently and accurately. The equipment uses power-assist technology to balance the load, creating a feeling of near-weightless manipulation, allowing operators to control materials with minimal physical force instead of having to use a lot of muscle strength.

Reducing physical labor, improving ergonomics

Instead of having to directly lift or hold materials by human strength, industrial manipulators support most of the load during operation. This helps reduce pressure on muscles, shoulders, back, and body parts that normally bear the load during manual lifting.

Especially for jobs with high frequencies, reducing the load on operators not only aims at safety but also helps maintain a more stable work pace throughout the production shift.

Supporting precise lifting, moving, and positioning

Industrial manipulators do not just serve up-and-down lifting operations. Depending on the configuration and gripping mechanism, the equipment can support moving, rotating, tilting, and positioning materials according to the requirements of each stage.

Good load control ability helps operators easily place materials in the exact position, limiting imprecise movements due to fatigue or having to exert too much force. This is also one of the ways to help reduce the risk of scratches, impacts, and material damage during handling.

Customizable according to load and factory space

An important advantage of industrial manipulators is the ability to design for each specific real-world problem. The equipment can be arranged as a fixed column, suspended overhead, or combined with a rail system, depending on the space and movement direction of the load.

With this approach, businesses can focus on solving the exact stage where issues are arising instead of having to change the entire material handling system.

Optimizing costs from a specific stage

Not all factories need full automation. In many instances, a manual lifting stage with high frequency, requiring many workers, or frequently causing material damage can already become a priority point for improvement.

Vietmani industrial manipulators can be considered as an intermediate solution between manual lifting and full automation: still maintaining operator flexibility while significantly reducing physical burden and supporting load control during operations.

When selected and configured correctly for the load, working frequency, space, and technological requirements, the equipment not only supports the operator but also contributes to building a safer, more stable, and more efficient material handling process.

Conclusion

Material handling costs do not only lie in labor or equipment but also come from invisible losses such as waiting times, damaged materials, injuries, and redundant operations. Therefore, optimizing Material Handling is an important part of increasing productivity and controlling production costs.

For manual lifting stages with heavy loads or high frequencies, Vietmani industrial manipulators can help reduce physical labor, support precise operations, and build a safer and more efficient material handling process.
