Evolution of Jimani’s Low Cost Hybrid Laser Marking Systems

Evolution of Jimani’s Low Cost Hybrid Laser Marking Systems

The Low-Cost Hybrid Laser Marking Systems have become the mainstay of Jimani's laser marking system sales. These systems have allowed us to standardize on budget-friendly laser marking system configurations that address the majority of laser marking applications.

We have completely discontinued the manufacturing of our Langolier systems which were expensive and almost always required custom features and hardware.

JIMANI-HYBRIDS-scaledThe Hybrid systems have continued to evolve. We continue to use Chinese-made JPT fiber lasers but we have resisted what seems to be the Chinese philosophy of use cheaper and cheaper components. We have stuck with the higher-end JPT laser sources even though JPT now offers many lower-end, less expensive models.

Like most things, lower price almost always comes with a compromise in performance. Beam quality is one of those compromises and we don't want our customers to suffer the consequences of lower output laser beam quality which affects laser power density at the workpiece being marked.

I still don't know of any company outside of Jimani that goes to the expense of using an external beam expander to reduce or expand focused laser spot size.

Although Jimani has stayed away from low-end models of JPT lasers, we have been willing to embrace changes in their higher-end models. We have started building systems using 80-watt laser sources in place of 60-watt laser sources. These lasers provide increased efficiency and use 48 VDC supply voltage instead of 24 VDC supply voltage. They are also capable of variable pulse width operation when used with Prolase Laser Marking Software. Jimani's standard fiber laser product offering is now 30-, 80- and 100-watt fiber lasers. 

Jimani has seen an increase in Low-Cost Hybrid CO2 Laser Marking Systems. Many of our CO2 system sales have been for thermal mug marking applications using Jimani's High Speed DCA Rotary. The DCA Rotary allows for fast marking completely around the circumference of a cylinder such as an insulated thermal mug. Thermal mugs have become an increasingly popular item in the promotional products industry and there is a demand for larger and larger imprints on these mugs. Most of these products are powder coated and CO2 lasers are the best choice of laser for this application.

We've built Low Cost Hybrid CO2 systems using both US made Synrad and Chinese-made Nanjing lasers. The Synrad laser is more expensive but is a far better laser. All modern CO2 lasers are "sealed beam" units and US technology is superior to Chinese technology for these types of lasers. From both a beam quality and overall reliability standpoint, the Synrad laser is a far better unit but is considerably more expensive than the Nanjing unit.

We have begun to investigate UV lasers in our Low-Cost Hybrid product line. UV lasers seem to have reached a point where they are reasonably priced, more reliable and easier to support than in the past. The Low-Cost Hybrid with a UV laser is not a current product offering but is something being seriously considered. Once we have more hands-on time with  UV lasers I'll write a blog post about our experience.

When I was first approached by a Chinese Fiber Laser Systems integrator several years ago, I was interested in investigating their products simply because the price point was remarkably lower than all of the traditional marking systems from US and European integrators, including Jimani and our Langolier family of marking systems.

After a few years of searching and trial-and-error system evaluations, we settled on a Chinese partner and an initial hardware configuration. The story behind my interest and my initial experiences can be seen here if you care to read it.

We now have several years under our belt of selling our Low-Cost Hybrid markers with some of the core components from China. We have discontinued sales and manufacturing of our Langolier systems and any inquiries we get for the Langolier are being redirected to Bell-Everman in Goleta, California. Bell-Everman was the supplier for most of the automation components used in Langolier. They are very familiar with the Langolier and better able to supply and support sophisticated automated applications. 

Over the last decade, the price of fiber and CO2 laser marking systems has decreased substantially. For most applications, our Low-Cost Hybrid systems perform as well as a Langolier at a third of the price. 

My initial thought was that the Low Cost Hybrid would provide a good starter system for very basic applications or those who wanted to dabble in laser marking at a modest entry level price. That initial configuration looked like this:


What I discovered after integrating and shipping a few dozen systems was that the capabilities of the system were anything but basic. The JPT fiber laser and the Galvo Tech scanhead have proved to be remarkably reliable.

When coupled with Leopardmark or Prolase Laser Marking Software, the system has the capabilities of providing the same marking quality as any of the laser marking systems that I have run across. After all, the main components of a laser marking system are a laser, scanhead, laser marking software, and control electronics, and all of those components in the Low Cost Hybrid are pretty darned good.

Packaging was a different story. The cost of bringing in systems from China was becoming expensive. Because of air freight costs, I was reluctant to bring in systems with larger configurations, such as full enclosures. I spoke to my Chinese partner, Ryan Wang of Focus Laser, about this. We agreed to test out container shipping by ship. This meant allowing for more shipping time and bringing in enough systems to justify the container cost.

The first container shipment contained items I would not have considered bringing in by air freight. The most notable new item in the container was a fully enclosed 60-watt fiber laser system, as shown in the photos below.

The full enclosure was well made, aesthetic and had a roomy interior. The interlocked front sliding door and swing open side panels provided lots of interior access. There was sufficient room for a manual X-Y table and/or a rotary indexer and there was sufficient Z axis focus travel for any of the standard focusing lenses that we use.

At the request of a customer in Mexico we then brought in our first fully enclosed Low Cost CO2 Laser Marking System. The packaging was identical except for a deeper rear panel to accommodate the additional length of the CO2 laser. Interestingly enough, Ryan at Focus Laser, strongly suggested that we not use a Chinese made CO2 laser.

Instead he installed a US made 60 watt CO2 laser which, by the way, tested out at over 75 watts through the lens. I have heard over the years that Chinese made CO2 lasers are not of the same quality as Chinese made JPT fiber lasers. I believe that because of Ryan’s reluctance to use a Chinese made CO2, he shares that opinion.

I’ve often said that the price of Chinese made fiber laser marking systems is a race to the bottom and that the Chinese tendency is to try and make the systems appear more full featured by adding cheap components that don’t work as advertised.

One of those components that is common on all imported marking systems is a red diode pointer that serves as a visible alignment laser. A red diode guide laser is typically mounted in an adjustable mount between the fiber marking laser and the scanhead. The red guide laser position is then adjusted so that it is aligned with the marking laser at the focal point of the lens.

The problem is that the adjustment mechanism is terrible and it is difficult to get the two laser spots aligned well. If anything gets bumped or moved at all, that alignment is lost and one might spend a few frustrating hours trying to realign it.

Jimani’s Langolier Laser Marking Systems have always employed a guide laser that is internal to the fiber laser module. This is a more expensive option but, since the red guide laser and the fiber marking laser share the same fiber optic path, they are always in alignment. We now use internal guide lasers in all of our Low Cost Fiber Laser systems with JPT lasers. 

By using an internal guide laser we no longer consumed the space in front of the scanhead used by the external guide laser adjustment mechanism. I spoke to Ryan and asked him to modify his optical housing such that we could install the same type of reversable beam expander in that freed up space.

We have used reversable beam expanders on Langoliers since the beginning and they have proved to be a very valuable feature. Ryan made those modifications and now every new Low Cost Hybrid Fiber Laser Marking System is provisioned to accept a reversable beam expander. If you are not sure why a beam expander might be a valuable addition to the optical path of a laser marking system, read this article.

It seems that instead of being caught up in that race to the bottom pricing structure, we have found a middle ground. Even though we will never have the lowest system prices, the Low-Cost Hybrid is evolving to a configuration comparable to the Langolier in both functionality and performance.

We also have the comfort of being able to support the equipment without using dirt-cheap prices as an excuse for poor quality or performance.
