Our Experience Works for You

Metlon Corporation has over 14 precision slitting machines in its plant that have all been custom- built in plant for specific applications over the last 25 years.  These slitters vary from 4” wide machines that can slit to widths down to .008” wide to slitters that can handle material up to 30” wide.  All of these slitters have the ability to hold tolerances of +/-.005” wide and many have the ability to hold tolerances down to +/-.001” wide.

We have the ability to slit onto many different ID cores and reels as well as various types of traverse spools.
As requirements have evolved over the years we have modified and rebuilt our slitters to handle different types of material and sizes apart from those for which they were originally designed.

  • Custom Slitting For Research & Development

One of Metlon’s first custom slitting jobs was in the days before Cassette sound recording tapes became popular.  In those days, .250” wide magnetic tapes winding from reel to reel were the most common ways for people to record music and voice, at home and in recording studios.
Metlon was approached by two of the major manufacturers of .250” sound recording tapes.  They had vast inventories of .500” wide magnetic tape that was made for digital storage on mainframe computers.  The tapes had minor defects that caused them to fail during formatting for digital storage. It was determined that while the tape was not useable as computer media, it was of a quality that would work well for sound recording.
Metlon had the ability to slit a .008” wide cut out of the center of the .500” wide magnetic tape, winding the resulting .246” wide cuts onto reels for use as sound recording tape.  This application gave the tape manufacturers a way to salvage thousands of dollars of defective inventory.

  • Cost-saving, Time-saving Capabilities for Clients

Another customer came to Metlon with a new thermoplastic film adhesive which was developed for use in the semi-conductor industry.  They needed the tape slit to many widths from 0.050” up to .250” with a slit width tolerance of +/-.001”.  Having spoken to a number of contract slitters prior to contacting Metlon, they were told that it would be necessary to purchase special tooling for the variety of  widths that they required, and that lead time for this tooling would run anywhere from 4 to 12 weeks.
Metlon maintains a vast inventory of tooling that is set up differently than what most companies use in the film slitting industry.  We were able to set up to slit any width from .050” up in .001” increments and hold a slit tolerance of +/-.001” with existing tooling which resulted in Metlon getting the job.

  • Increasing Your Capabilities; Creating New Business Opportunities for You

Metlon had a client sending in amorphous metals in supply rolls that were 1”to 4” wide and 12” to 14” in diameter for slitting to narrow widths, which we serviced for over 15 years. The supply rolls being sent to Metlon were on 3” ID cores and weighed between 50 and 100 lbs. each. 
In 1997 this client had an opportunity for new business requiring much larger, heavier rolls of amorphous metal be slit..  The supply rolls for this opportunity were on 12” ID cores and weighed between 1,200 to 1,800 lbs. each.  Finished slit coils had to be on 8” ID cores with weights up to 400 lbs. each.  In order to satisfy these new requirements, we re-built both the supply stations and take up stations on one of our slitters. Eventually, this job grew to the point that it was necessary to re-build yet another slitter to handle the customer’s demand.
Metlon ran this material for many years, until our customer lost the business to a competitor overseas.  At that point, the slitters were once again converted, back to their original use.

Narrow Width Slitting To Precision Tolerances

Visualize a human hair which is approximately 0.0025" in diameter. Now visualize cutters capable of cutting materials to just three times the width of a human hair. Metlon’s unique custom slitting capability allows them to gang slit 278 ends simultaneously to 0.0078" wide and wind each end on a separate traversed spool. In this example, the material being slit is 0.001" polyester film.

Plastic films, papers, metal foils, impregnated fabrics, and laminations of these are among the wide range of materials we custom slit today.

Metlon specializes in extremely narrow widths, down to .008" (.198mm) and non-standard custom slitting and we can work with very close tolerances (±.001").

 

Extreme Accuracy

Customer requirements of extreme accuracy are common. As a leader in the converting industry, Metlon is known for custom slitting to extreme tolerances.

Example: One customer asked whether we could slit a new film to any width between 0.050" and 0.750" in 0.001" increments. Also, he asked if we could hold our accuracy to ±0.001". Metlon has satisfied this customer’s requirements for many years with no reported rejects.

 

Proven Precision

Metlon is not only able to slit to very accurate tolerances, but is also able to measure its results. Several different methods are used to measure accuracy for customers. Work which demands the greatest accuracy is measured with a Zygo Laser Micrometer. This precision instrument will measure from 0.010" to 2.000" wide in increments of five decimal places. In addition, certified copies of actual measurements are available.

 

Registration

Extremely accurate registration in very narrow width slitting is one of Metlon's specialties.

Example: One job involved a 16 mm (0.630") wide film with 0.030" wide numbers printed down the center. The customer required that the film be slit to a final width of 0.040" and that the printed numbers be kept in the center of the finished width.

The customer asked a number of converters throughout the country to do this work and he was told it was impossible. Metlon was the first to try and was successful. The customer continues to place orders with Metlon for this product.

 

Engineering Experience Works For You

When Metlon receives your order, the production department decides how to complete your order to yield the highest quality at the lowest price.

If special tooling will do the job better, reduce waste, improve quality, increase production, etc., then our experienced engineers design the necessary parts. In almost all cases, Metlon's capable craftsmen, working in our well-equipped machine shop, manufacture the parts necessary to meet your finished product specifications. Our ability to make machine changes immediately, affords us flexibility and control, and insures you, the customer, the best possible product.

 

Cooperative Development With Customer's Engineers

Because we are specialists, customers call upon Metlon to do unique and experimental work to aid in the development of new products. Both large and small companies have frequently test-marketed new products with the help of Metlon, prior to investing in their own slitting machinery.

In addition to mechanical changes to aid customers in operational use, many recommendations have improved customer product recognition with special identification printing.

Suggesting alternatives and solutions is often where our engineering experience counts most.

 

Quality Backed By Integrity

Each customer's custom slitting order starts with an individual customer specification checklist which includes cutter set-up, core or spool size, tension range and other controls necessary to meet the customer's requirements. A supervisor must approve the first work to come through the cutters. Frequent spot checks are made by the operator throughout the run. Quality control makes the final check for accuracy, quality of cut, quality of winding, appearance of the material and other job specifications.

By far, the single most important feature in quality control is the integrity of our employees. All are carefully instructed on how to run the machines, read a customer's specification checklist, and report all discrepancies to their supervisor. We are very proud of our employees and their continued effort to produce top quality work.
