How to Boost Worker Productivity in a Manufacturing Setting

On this blog, we often talk about the ways investing in advanced sheet metal manufacturing technology can help improve productivity. However, machinery is only half of the equation in the manufacturing industry and the human element is often overlooked as working on employee productivity tends to be a lot more complex than simply upgrading your machinery. Despite this, if you can get it right, improved worker productivity can have a significant impact on your bottom line and also help improve both  job satisfaction and morale. This week, we look at some of the ways sheet metal manufacturers can improve worker productivity.

learn how to boost worker productivity

Examine existing workflow

The first step in improving productivity is to identify inefficiencies in the workflow. To do this, you need to evaluate the processes, technology and of course the people required to produce your product. When focusing on employee productivity, look closely at things like procedures, communication tools and channels and resources to see if there is room for improvement. From there, value mapping can be an effective way to identify and monitor process improvement to see the impact on the workflow.

Anti-fatigue matting

Anti-fatigue matting can play an important role in boosting productivity as it enables workers to perform for long stretches of time without any pain. Anti-fatigue matting improves posture and blood circulation, reduces body aches, helps preserve energy levels and helps workers feel physically comfortable and supported throughout the day.

Invest in employee education

In an industry that is constantly evolving both in terms of technology and procedural processes, there are plenty of opportunities for employees to advance their professional skillset which ultimately adds value to your business and ensures you remain up to date with the latest specialist technologies.

Foster a team environment

Although it’s made up of separate stations, a manufacturing floor is most productive when everyone is united and working towards the same goal and lag, waste and conflict is kept to a minimum. Creating a co-operative environment requires a dual approach of running regular team building exercises and working with employees individually to ensure they feel comfortable and see themselves as part of the team.

Tips for Getting the Most Out of Your Ironworker

Endlessly variable and hardworking, ironworker machinery simplifies many difficult metal fabrication tasks. This week, we look at how you can improve the productivity of this already invaluable piece of machinery.

getting the most from your ironworker

Ironworkers have a punch, but don’t throw away your drill

Ironworkers tend to be limited in the hole sizes they can punch relative to the thickness of the material and cannot be used to punch a hole smaller in diameter than the material thickness.

More is better when it comes to throat depth

Throat depth should be deep enough for most of your work and be able to punch your largest part. Remember, you can’t add it later and if there is a special job, a drill can do the work instead.

Think carefully about the ironworker table

If you plan to use your ironworker for pipe notching or bending, it’s important to choose a table where the die holder is attached in a user-friendly way. Die holders can be attached with T slots, drilled holes, or tapped so it’s important to closely inspect before investing.

Die holder positioning is also important

If you need to punch close to the web, get a die holder where the die is near the edge of the holder rather than in the centre, as this can inhibit punching ability.

Different types of angle iron shear have different pros and cons

The slug-type angle iron shear is the best choice for those seeking a good cut quality, but it does cause some material loss and shimming. It also requires blade changes. If you need to cut a large piece of iron and want to avoid wasting materials however, the cropoff shear is the best choice, although it produces a lower cut quality.

The flat-bar shear is great for fabricating base plates, but quality varies

Different ironworkers offer different quality levels at this station and the rake angle in particular, can have a significant impact on the resulting cut quality. Broadly speaking, the higher the rake angle, the more distortion the drop piece has causing the material to roll or bow.

Metal Commonly Used in Construction

The sheet metal fabrication industry produces a large amount of metal that goes on to be used in the construction industry, so in this blog, we thought we’d look at some of the most common metals used in architecture along with their unique structural properties.

metal

Aluminium

Aluminium is a fantastic construction material as it is resistant to corrosion, ductile, and lightweight yet strong. It is also highly conductive. Architects favour aluminium as it is easily moulded, making it suitable for a wide variety of purposes including ceilings, walls, window frames, roofing, HVAC ducts and even bridges and other industrial construction.

Copper

Copper has been used for a variety of purposes for thousands of years and is valued for its conductivity, corrosion resistance, strength and ductility. Within the construction industry copper is often used as piping and tubing, along with cladding, electrical wiring and even roofing.

Iron

Two typed of iron are commonly used in construction: cast iron and wrought iron. Cast iron is melted, poured, and moulded, and is often used in large architectural projects. Wrought iron is rolled in the final production stages and is often riveted to make structural components like beams, trusses and girders.

Steel

Steel is commonly used in the construction industry as it is incredibly strong, durable, ductile and malleable. It is a fantastic conductor and can be recycled over and over again without degradation. Steel is used to make building frames, along with roofing, handrails, balustrading, cladding and more. Steel comes in several variations, including stainless steel and carbon steel.

Titanium 

Titanium is another lightweight metal commonly used in the construction industry. It is often used to construct heating and cool systems as it is highly corrosion resistance, however it is also found in pipes, roofing and even frames.

Sheet metal manufacturers play an important role in construction, as they provide the construction industry with much of their materials. If you’re a sheet metal fabricator in need

10 Interesting Facts About Laser Cutting Technology

In the sheet metal manufacturing industry, laser cutting remains the gold standard in terms of speed and precision but did you know this futuristic technology was first theorised about over 100 years ago? This week we uncover 10 surprising facts about the history of laser cutting technology.

laser cutting technology

 

  1. The relationship between energy and the frequency of radiation was first deduced by physicist Max Planck in 1900 who said energy could only be emitted and absorbed in chunks.

 

  1. This theory was extended by none other than Albert Einstein in 1905 with his paper on the photoelectric effect. In 1917 Einstein presented his theory on stimulated emission, the process which makes lasers possible.

 

  1. However, it would be 40 years before scientists would be able to prove Einstein’s theory in the lab. This was done in 1954 by Charles Hard Townes with the help of Herbert J, Zeiger and James P. Gordon.

 

  1. Originally the strength of a laser was measured in ‘gillettes’ which refers to the number of razor blades a laser beam can cut through. Today, the strongest laser is as powerful as a hydrogen bomb.

 

  1. Laser is an acronym which stands for Light Amplification By Stimulated Emission of Radiation. The term was coined by Gordon Gould in 1959.

 

  1. Ruby laser technology was first used in a cutting context to drill holes in diamond dies in 1965.

 

  1. In 1963 Kumar Patel developed the first Carbon Dioxide laser, which was more powerful and less expensive than the ruby laser previously used. A CO2 laser was the first to be used as for cutting metal in 1967 when it was used alongside oxygen jet cutting to cut through a 1mm thick sheet of steel.

 

  1. The Being Company was the first to use laser cutting technology in a manufacturing context in 1970, it invented multi-beam laser cutting technology and used it to cut through ‘hard’ materials such as titanium.

 

  1. 3D laser cutting was pioneered in 1979 and employed a 5 axes rotation system.

 

  1. Laser cutting is renowned for its accuracy and indeed laser measuring is accurate to just over a nanometre (a billionth of a metre).

How to Break in Your Bandsaw Blade Properly

Breaking in a bandsaw blade properly can prolong blade life, lead to faster cuts for longer and ensure more consistent performance. The teeth on a new band saw blade are extremely sharp and if they are not broken in correctly, the edges will chip and wear out faster, meaning rougher cuts in the long run. Today, we reveal the correct procedure for breaking in bandsaw blades without needing to buy anything new.

One useful analogy used in the industry is to think of the bandsaw blade as a new pencil with a sharp tip. You cannot apply too much pressure on a new pencil tip without it breaking and the tip becomes blunt with extended use. Bandsaw blades are very similar in this way. Breaking in a saw blade properly wears off this razor sharp edge and prolongs the blades cutting ability. Each manufacturer will have their own recommended method for breaking in their band saw blades. However, they all share the same key principles which we have outlined in the break-in procedure below.

Karmetal KMT 300 KDG Semi-Automatic Mitre Bandsaw

KMT 300 KDG Semi Automatic Mitre Bandsaw

4 Easy Steps to Breaking In Your Bandsaw Blade

1. Set and use the recommended band saw speed (as per manufacturer’s recommendations)
2. Reduce the feed pressure/force control to approximately 50% of the normal cutting rate. Soft materials like aluminium require a larger reduction in cutting rate (around 50%) than hard-to-cut materials such as stainless steels and hardened steels (which require the feed pressure to be reduced to around 75% of the normal cutting rate).
3. Run at these settings for the first few cuts or around 50 – 100 square inches of easy-to-cut materials (323 – 645 sq. cm) and around 25-75 square inches of hard-to-cut materials (161-484 sq.cm). Begin the first cut at the reduced rate (make sure that the teeth are forming a good chip). Once the blade fully enters the workpiece you can gradually increase to the normal cutting rate or desired cut is achieved. With hard-to-cut materials make gradual increases in feed rate/force over several cuts until normal cutting rate is achieved.
4. Avoid unnecessary vibration (slight adjustments can be made to band speed during this process in the case of excessive noise or vibration).

Following this procedure as well as appropriate daily maintenance practices will allow your bandsaw blade to stay sharper longer, increase the consistency of your cuts and ultimately increase blade life.

Consult your supplier regarding the best break-in procedure for your machine

Once the blade is broken in, you should use the recommended band speed as per manufacturer’s indications. It is best to verify the correct break-in procedure for your particular band saw and relevant daily maintenance required with your supplier. Contact our friendly support team o 03 9794 6675 to discuss Karmetal and Durma band saw break-in and other maintenance procedures. We stock a range of automatic and semi-automatic models and can provide you with the right advice to help you keep your band saw blade in good working order longer and ensure consistent performance.

A Guide to Shear Maintenance

Most sheet metal manufacturing plants are fitted with shears – hand shears, foot-operated punch and shears, or both. Shears are incredibly useful in the sheet metal fabrication industry, so it’s important to keep them well maintained to ensure optimum performance. Read of for some essential shear maintenance tips.

shutterstock_502702249

Know the machine’s limits

It’s important to understand your machine’s function and limits, and to keep loads within the parameters outlined by the original equipment manufacturer. Your shears are designed to cut workpieces of a specified thickness and width, and exceeding load limits will likely damage your machinery. It’s important to set the shear blade properly, allowing for the appropriate clearances. When clearances are too tight, they result in poor cuts due to the metal workpiece being jammed between the blade and the machine. Clearances that are too loose put strain on the machines components, resulting in premature wear and machine failure.

Regular inspections are a must

Regular inspections must be carried out to ensure your shears are in working order. The inspection should include making sure the shears are properly executing their operational functions, checking bearings for lost motion and wear and ensuring that all emergency and safety functions are working.

Repairs should be made ASAP

If your shears are at all damaged or worn, repairs or adjustments should be made immediately. Putting off repairs can be extremely costly, as you will not only have to cover the costs of the repairs, but also the resulting damage. Immediate repairs are also vital to ensure the safety of your workers and prevent catastrophic accidents. Special attention should be paid to safety features such as the clutch and brakes and damaged shears should not be used until repairs are complete.

Cleaning is essential

Shears must be cleaned regularly to ensure full function. This includes thoroughly cleaning the lubrication system (along with continuously refilling and properly filtering it) and maintaining the air system to ensure the air is clean.

It’s important to pay close attention to your shears, and all sheet metal machinery, to ensure they are functioning correctly and efficiently.

New Press Brake Technologies: Why They’re Worth the Investment

For most sheet metal manufacturers, investing in a new press brake is not usually at the top of their priorities list. For a long time, press brake technology has lagged behind other sheet metal machinery in terms of automation. As a result, most companies have a manually operated press brake that requires a substantial amount of programming on the floor and as a result, is unable to keep up with the other machines speed of production. However, over the past couple of years press brake technology has evolved substantially to the point where many functions are automated and modern machines have uptime comparable to other sheet metal technologies. This week, we look at exactly what those technological advances are and the impressive impact they can have on productivity.

advanced press brake technology

Repeatable press brakes

The most common upgrade choice for businesses is the repeatable press brake which draws from material databanks to automate press brake moves and limit the amount of manual calculation required.

 

Software that adapts according to material behaviour

The software behind press brake technology has also become substantially more sophisticated. One exciting innovation is the software’s ability to adapt to material behaviour in real time. Using internal sensing and external laser sensing, this software can account for material variations including crowning and deflection.

 

Adaptive bending

Many new press brakes not only make it easy to calculate spring back and deflection before bending, but can also account for varying tensile strengths and adjust both deflection and calculation errors during the bend. This deflection adjustment is achieved through either mechanical or hydraulic means on the lower beam. Some systems also continuously monitor tonnage throughout the cycle and if an adjustment is required, the crowning cylinders are engaged whilst the cycle continues.

 

Offline programming

Offline programming eliminates manual programming on the factory floor and thus enables the press brake to remain in constant production. Whilst previous offline program technologies struggled to manage variables such as the bend radii of the available tooling, the newer breed of offline programming develops the press brake program directly from a 3D drawing, but before the blank size is determined. This way the properties of the press brake can be quickly programmed in by the operator to ensure accuracy.
