The information below is intended to be helpful for customers who wish to learn more about enclosure design. Also, please use our online support if you have questions for our expert design staff. It is most economical to use a single bend radius throughout the design, but if necessary, you can utilize multiple radii. Use this document to choose values that are both manufacturable and meet your needs. If you need help choosing a value, contact us at info protocase.
Alternatively, you can design with any value, and we can adjust it for you later in the process. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by Protocase.
It is possible to choose other bends, but tooling charges may apply. If you have any questions or want to discuss your design, contact us. We are here to help! Folding is the most accurate way for Protocase to bend parts.
If you can stick with folder radii, it will get your parts through our manufacturing process faster with the most precise dimensions.
Bend Radii & Minimum Bend Sizes
However, if folder radii do not work for you, we can manufacture parts using our press brakes. In fact, press brakes are more flexible and can bend certain parts that the folder just cannot do. Geometry of tooling imposes a minimum bend dimension. The diagram shows one such mechanism. Refer to the chart for values for folder as well as various press brake tooling combinations.
Tip: Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. Please note: The bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius.

Now, multiply that answer by the plate thickness.
If the material is 0. So in this case, the minimum inside bend radius is 2 times the material thickness. A: You have the formula correct at 0. However, I believe you misinterpreted the meaning and how it relates to your bend allowance chart. The calculated 0.
The minimum inside bend radius is even larger when bending with the grain. In steel between 0. Also note that all these are just examples; actual minimum radius values vary by grade. For steel, aluminum, and stainless, you will find a variety of minimum bend radii-to-thickness ratios, and you will need to research these values in data provided by your material supplier.Suspended zero tolerance policies
The radii from the bend allowance chart see Figure 2 is based on 15 percent of the die opening and represent basically a one-to-one relationship between the material thickness and the inside radius when using the recommended die opening of 5 in. By using the 5-in. Assuming you have the tonnage and could force the material into a die opening only 2. Nonetheless, some folks do this if they have high-tonnage machines.
Figure 2 This portion of a bend allowance chart gives the recommended inside radius, not the minimum inside radius that can be produced. Also note that this is not a bend deduction chart. The bend allowance is used to figure the bend deductions you need for the flat layout.
The 5-in. I, along with your press brake manufacturer, would not recommend using a smaller die opening, if for no other reason than to avoid damage to your press brake and tooling. If your die opening is less than 8 times the material thickness for sheet metal, or less than 10 to 12 times the material thickness for plate, you will see a dramatic increase in the amount of pressure required to bend the material.
Also, lifting the workpiece during forming can increase the tonnage required dramatically. Figure 3 shows gauge 0. The material will need to be lifted during forming over a 1. To calculate the additional tonnage, you need the weight of steel per square foot for the given thickness, which you can get from your supplier or on gauge charts for common materials. The weight of ga. Next, multiply the total weight by 60 one-half of the sheet width in inches and divide that by half the die opening width.
Finally, divide the bending force by 2, lbs. Total weight lbs. Figure 3 Lifting the workpiece during forming can increase the tonnage required. Next, use this formula to calculate forming tonnage for mild steel all variables are in inches unless otherwise noted :. You can reduce the tonnage by using a larger die opening, but this will require you to take into account a larger inside bend radius and, therefore, a larger bend deduction and bend allowance for the flat-blank calculations. For instance, a die opening of 1.Often, in the rolling and bending industry, we field requests asking about the minimum radius to which we can roll or bend a piece.
In some instances, an estimator can quickly say yes or no based on prior knowledge and bending experience. There are many factors to take into account when determining the minimum radius such as the material composition, shape, and size. In some instances, a rough guide for minimum radius bending would be to use a multiple of the piece diameter.
For example, on a 2 inch pipe elbow, common bend measurements may be referred to as 2D, 3D, or 5D. In these cases, the 2D would reference a centerline bend radius of two times the diameter. This type of bending is usually performed on a rotary draw bender for speed and precision, which requires specific tooling built for each bend.
So, even though it may be possible to give a piece a 2D or 3D bend, a 3. For tight rotary draw bending, maintaining a bend radius that is a whole number multiple may increase the capability of the steel bender to meet your needs.
While it may not be a minimum for every bender, a 3D bend radius is a commonly used starting point for minimum radius bends. As a piece size gets larger, pre-made tooling for tight bends will be less common. In these cases, the minimum radius will likely need to increase beyond a 3D size.
Another important factor to consider when looking at pipe or tubing is the wall thickness of the piece to be bent. Increasing the wall thickness on a tight radius bend generally improves the final quality of a rolled tube as well as lowers the minimum radius a piece can be rolled with minimal distortion issues.
Material used can also change the minimum bend radius. One previous job which provides a good example of this used some 8 x 4 aluminum tubing rolled the hardway to a 16 foot radius. The same tubing rolled in carbon steel could be pulled much tighter.
However, the aluminum tubing began to crack, possibly due to age-hardening coupled with the tight radius. To solve the issue, the material was sent out to be stress-relieved before rolling was continued. In the end, this caused a much improved final product for the customer with no additional material cracking issues. As you can see, determining the minimum bend radius for a piece has many factors to take into account.
Available tooling, tube size, material thickness and composition are all components that can add into what the minimum bend radius is for a piece of metal. WordPress Di Business Theme.

The decline of campus-based higher education. A degree used to be a virtual guarantor of improved employment. Half of college graduates under 25 are unemployed or doing jobs they could have done with just a high school diploma. And the comprehensive study, Academically Adrift, found remarkably little freshman-to-senior growth in those core areas that college is supposed to improve: critical thinking, analytical reasoning, and writing.
The trend toward learning outside the halls of academe will continue. More spirit, less religion. The Pew Center reports that the fastest growing religion is no religion.
But people will continue to want a source of inspiration and comfort beyond the quotidian. So not-deistic spiritual practices, for example, Buddhism and the related yoga, martial arts, and meditation should flourish.
In light of these predictions, is there anything you want to consider as you're doing strategic planning at work or even in your personal life.04 Bend Theory
Marty I like these predictions but I think you're being a little too optimistic for the NEAR future. There will be civil unrest and things will get worse before they get better, especially with both the right and left wing being unable to get their heads out of their own asses.

According to Football Outsiders, the Eagles allow the fewest running back yards per rush (2.
However, Gurley can still overcome a good defense. Against the Arizona Cardinals (Football Outsiders ranks them fourth against the run) last week, the former Georgia Bulldog had 158 yards from scrimmage on 25 touches. Gurley also gained 154 yards from scrimmage (and a touchdown) versus the Cards on October 22.
Gurley assumes a lot of the Rams' volume. He's touched the ball 271 times in just 12 games this year and is on pace to surpass 350 for the season. Therefore, he should receive plenty of opportunities to score.
In fairness, that number has come down from 51, so it's clear that sharp bets have gone heavy on the under since the line opened. However, 48 is still the second-highest number on the board for the remainder of the week, so don't be surprised if this game ends up being one of the higher-scoring Week 14 matchups. That means Gurley can certainly find his way into the end zone at least once.

Product reviews by real customers can help other consumers contemplating a product to decide if it is worth buying. If the reviews are positive, this can translate into a big sales lift for the retailer, so it makes sense that a business would want to encourage public customer feedback. Not only is it unethical to pay someone to leave a positive review, but if it's discovered as a fake, your business reputation could take a serious hit.
For this reason, Amazon recently banned incentivized reviews to ensure that all product reviews are authentic and genuine.
Letting your customers know that reviews help increase your business, or help you figure out where your product or service needs improvement, will encourage them to leave a review.
The point of showing reviews and testimonials is to share your brand with prospects and being genuine is always the best practice. If you do choose to offer free or discounted products in exchange for a review by an "influencer," such as a blogger or social media user with a lot of followers, be aware that the Federal Trade Commission has a set of detailed Endorsement Guides for anyone publicly endorsing a product at the request of a brand.
According to the FTC's website, these guides are meant to disclose advertiser relationships and "reflect the basic truth-in-advertising principle that endorsements must be honest and not misleading. FTC guidelines notwithstanding, Matt Iswariah of Luxzura said he thinks influencers should always mention if they received a product for free or at a discount, even if they're not doing a full review.
I see many blogs that do include disclaimers to show how they received the product," Iswariah said. If a customer agrees to leave you a review, keep an eye out for it online, Osmond said.
