Bender for Sale – Call Today

The last quarter of the year is a popular time to purchase a bender for sale. Many companies want to get their machine and tooling on the books before the end of the year.  It is another reason why a bender for sale and tooling orders will back up in the last quarter.  It is not uncommon to add several weeks more for a tooling order.  And, as a bender for sale are sold out of stock, new production is the only way to go.  So even though a bender and tooling purchase orders are received before the end of the year delivery will be in the New Year. For that reason, it pays to plan ahead when buying a bender for sale.

What are the steps to get a bender?

First and foremost, get your quotations early.  As mentioned the time of year can greatly influence the delivery of your bender for sale and the required tooling.  The quotation process will require the right questions are asked.  This ensures you get the correct bender for sale and tooling.

Bender for Sale Quotation Process

Preparing for the quotation process requires just a few steps. You will want to know the bend specifications for each bend.  This includes outside diameter, wall thickness and material type.  In addition, the radius of the bends and degree of bends.

Outside Diameter

First, know the outside diameter of the tube or pipes you will bend on the bender for sale.  It is the starting point for the right model of bender for sale.  Recall that tube and pipe sizes are different.  Tube is measured by actual OD so that 2” is actual 2” OD.  A 2” pipe size actual OD will be 2.375”.  This is important as it will not only affect the capacity of a bender for sale but the way in which the tooling is engineered.

Material and Wall Thickness

Secondly, know the material you will use for your bender, whether it is stainless, mild steel, Inconel, aluminum, and so on. The material will also have a wall thickness. It is usually noted in inches, millimeters, gauge or schedule. If in doubt of the actual wall thickness, check with your material or supplier. This is an important specification for the tooling on a bender for sale.  It can make the difference between requiring a mandrel or not. It also determines how many balls are required for the mandrel.  The material will also determine if a mandrel is made of bronze or chrome.

Degree of Bend

Third is the degree of bend.  This helps denote the amount of torque required by the bender to make the bend. If the bender for sale is at top capacity for a job it may not be able to pull a 180 degree bend at production level. However, it could do 90 degrees. It also factors into the mandrel with ball requirements.  Degrees of bend along with rotation to the next bend can affect any interference with a bender for sale. And lastly, degree of bend helps to determine the final engineering of the tooling.

Centerline Radius and Inside Radius

Lastly, the radius determines the size of the bend die for a bender.  Or, the dimension area the material will bend around.  Know if you are measuring your radii as a centerline radius (CLR) or an inside radius (ISR). Also know how to measure it.  See the figure below and note centerline radius (CLR).  Typically, CLR’s are used with round tube.  CLR’s measure point ends halfway into the material.  ISR’s, which measure just to the inside edge of the material, are typically used for square or rectangular tube.

What if you only have a sample of the part and don’t know the radius for your bender for sale?

Place the sample tube or pipe that you want to bend on a large piece of paper or cardboard on the floor.  Trace the tube or pipe that you would like to mandrel bend onto the cardboard.  Continue the pattern until you have made a full circle with the tubing or pipe you are working with.  Measure (in mm or inches) from the center of the tube or pipe to the center of your drawn circle.  This straight-line measurement to the tube or pipe is the centerline radius of your tubing you want to rotary draw or mandrel bend.  For inside radius (ISR) measure from the center of the circle to the inside edge of the tube or pipe as shown in the previous figure drawing.
