Overview
What is Traceless press brake tooling
In today's highly competitive market environment, product quality has become the basis for enterprises. In order to meet consumers' high demands on product appearance and performance, many industries have set higher standards for tooling technology during the production process. In this context, the Traceless press brake tooling has emerged as a specially designed tooling designed to avoid producing marks or indentations on the surface of the workpiece. Such toolings play a vital role in industrial processing and production where high precision and appearance are required.
The non-marking die is a die with an innovative design concept, whose main feature is the ability to minimize damage to the surface of the workpiece during machining, guaranteeing the appearance and dimensional accuracy of the workpiece. This kind of tooling is made of special material and process, with good wear resistance, corrosion resistance and high strength to ensure that it can maintain stable working performance during long time use. Traceless press brake toolings are widely used in many industrial fields, such as automobile manufacturing, electronic products, home appliances, plastic products and so on. In these industries, the appearance and dimensional accuracy of the products are of paramount importance, so the use of Traceless press brake tooling production has become a key factor in improving product quality.
Specific types
Ball Traceless press brake tooling
Ball Traceless press brake toolings play an important role in sheet metal bending processing. Their design is unique in that the workpiece comes into contact with a tungsten carbide mandrel on the lower die during the bending process, which rotates in the direction of sheet movement. This design allows the workpiece to change from traditional sliding friction to rolling friction when in contact with the lower die. This rolling friction dramatically reduces the possibility of indentation and abrasion on the surface of the workpiece caused by extrusion, effectively improving the appearance quality and machining accuracy of the product. However, although this tooling design can significantly reduce the indentation and abrasion, but in the bending process of soft plate, it is still difficult to completely avoid bending indentation, because there is still a certain amount of extrusion pressure between the lower die roller and the plate
Tension spring type Traceless press brake tooling
Unlike ball Traceless press brake tooling, tension spring Traceless press brake tooling are designed to take advantage of the mechanism by which the upper die presses the workpiece into the lower die body. In this type of die, the workpiece is in contact with the plane of the rotating flap, which rotates in the lower die body. There is no relative sliding of the workpiece against the rotating flap during the entire bending process, and the workpiece is in face contact with the rotating flap. This surface contact eliminates indentations and abrasions on the surface of the workpiece due to extrusion. Therefore, the spring-type Traceless press brake tooling effectively improves the appearance quality and processing accuracy of the workpiece, especially suitable for workpieces with high requirements on appearance.
Advantages of Traceless press brake toolings

Difference with ordinary tooling
The difference between precision toolings and ordinary toolings is mainly reflected in the accuracy, drawing design and tolerance control.
Precision requirements
The key dimensions of precision toolings are usually very demanding, with no skew or deviation allowed. This means that when making a precision tooling, the skew and deviation must be minimized as much as possible.
Ordinary toolings are relatively loose in the requirements of key dimensions, allowing a certain degree of skew and tolerance. Tolerance bands can be fully utilized when making them to reduce the strict requirements on dimensions.
Drawing design
The drawing design of precision tooling needs to be more comprehensive, complete and accurate. Need to consider the size, location and processing mode of each part. Try to use inserts to reduce the impact of manual processing.
Drawings for general toolings are relatively simple and may not require excessive inserts and fine dimensional control. Hand machining techniques and processes may play a greater role in common toolings.
Tolerance Control
All parts of a precision tooling require tight design tolerances. Not only the working part of the cavity and core, but also the dimensions related to the mounting position of all inserts should be strictly limited, usually within plus or minus 0.005.
General tooling tolerance control is relatively loose, can be in the range of plus or minus 0.01 or greater tolerance control
