If you’re like most rollforming shops you are most likely producing panels on a rollformer and trim pieces on a folder.  This is an excellent way to establish your business as it provides maximum flexibility and versatility in a compact single machine.  But what happens when you want to grow and expand your business only to realize that trim production is now your bottleneck? Metal Rollforming Systems has a number of valuable options that will significantly increase your production while saving you countless man hours of labor.

Production Times

The average 10’ corner takes 1 minute and 25 seconds to bend on a single folder.  That includes the operators time to make 3 hits on each hem, flip it and form it into a complete part.  This does not include any programing time or raw material prep.

Production Rates

hemming machine increases production by allowing the operator to insert the part a minimal number of times increasing folder productivity from 30% to 50% depending on the part profile.

Trim machines can increase production exponentially.  With the capacity to produce up to 650 pieces of 10’ trim in one hour it doesn’t take long to recognize a return on investment.  In the metal roofing industry, it is foolish to think that you will ever get away from producing at least some of your trim on a folder, but as you can see the more trim you can rollform the less man hour required.  This increases profit on trim sales and reduces the bottle neck of trim production resulting in increased sales company wide.

Man Hours Required for Trim Production

This is an example of the average time it takes to produce 500-3000 pieces of trim with various equipment; folder, hemmer, and trim machines.  


Profit Margin

Trim components are already one of the most profitable items sold by rollforming companies.  How would you like to significantly increase that margin? A single folder bending an average double hemmed part will see an average labor burden of around $0.45 on each part.  Add a hemmer to your existing folder and reduce that down to just over $0.30. Rollform approximately half your parts and decrease the labor burden to just over $0.20 per part, and the savings just keep growing the more parts you rollform.

Labor Burden per Part

As your company grows, so do the savings associated with a trim rollformer or hemmer.  You can see on the graph below as the piece count increases linearly, the costs compared to trim rollformers / hemmers increases exponentially.

Evaluate your needs / determine your budget

Now that you understand the advantages and savings associated with rollforming your trim profiles or a portion there of you can begin to hone in on the right fit for your company.  There are a number of variables and factors that combine into determining the savings associated with rollforming trim.

1. Find the right fit

Often times a newer company can get overwhelmed with trim in the spring or fall during peak season.  Seasonal needs may not warrant a full trim machine but may be better handled with a hemmer. Hemmers have the advantage of a low initial purchase price and the ability to provide hemmed edges for all parts going on the folder making them extremely versatile.  Even if future plans call for trim rollformers, you can continue to recognize savings from your hemmer for years to come on custom profiles.

2. Profile selection

If volumes necessitate a trim rollformer it is best to first determine the proper profiles based on the formula (time to produce x annual qty).  What you may find is that your largest volume part may not save you the most production time.  Once you have ascertained your 4-8 most laborious parts review your budget and determine which machine(s) make the most financial sense.

3. Final Machine Selection

Metal Rollforming Systems designs, manufactures, and sells a wide array of equipment that will meet the needs of any company looking to expand their trim production.  From hemming machines, to single trim rollformers, all the way up to multi trim lines with the capability of producing 4-6 profiles.
