Die tools
Each die tool is made on the basis of drawings or designed by our experienced designers in accordance with the expectations of the customer.
Material for making a die tool
The die tool manufacturing technology depends on the future operating conditions of the die stamping equipment and the load on them. And here the customer needs to immediately decide on two main questions: What material will the product or subproduct be made of? What production load should be carried out by the die tool: small-scale, piece or mass production?
For the processing of non-ferrous metals and thin sheet steel, common high-strength alloys are used. When working in more severe conditions, the matrix metal undergoes additional surface hardening (quenching). Die tools at our plant can also be made with additional coating (PVD coating), which extends their operation time to the maximum and allows you to save on maintenance in future.
It is the cooperation with only reliable suppliers of materials that allows you to increase significantly the working life of the die tools produced at Sumar Tools plant. For the manufacture of die tools, we use high-quality tool steels from companies such as Uddeholm (Sweden) and Böhler (Austria).
What types of die tools can be ordered from Sumar Tools plant? The main types of die tools for metal that are produced at the Sumar Tools plant:
Punching die tool
More than 95% of the total volume of work on sheet-metal forming is done by punching out the parts. Punching is commonly used in cold forming operations. The technological process can imply both the initial production from a strip or tape by punching the product, and an intermediate or final stage (for example, during perforation forming).
Drawing die tool
It presses volumetric shapes through sheet metal: grooves, channels, spherical recesses. Or it draws out of the subproduct with an increase in its linear dimensions (often used in the production of metal packs).
Molding die tool
It is designed to change the shape and size of subproducts obtained from a sheet, strip or thin-walled semi-finished products. In the process of shaping, they are deformed plastically, without leading to a destruction.
Combined die tool
It uses several die stamping operations in one cycle. The universal die tools are complex equipment and require careful engineering calculations when designing.
Progressive stamping die tool and double-action die tool
For each mold action, one part is issued, which requires several sheet forming operations during the manufacture. In multi-stage die tools, the most common operations used are punching, perforating, drawing, bending and flanging.
Bending die tool.
It modifies sheet metal geometry in straight lines. Sometimes it cuts additional holes, but does not create relief shapes. Bending die tools are common on production lines that make simple parts.
Stamping die tool
It is used when creating relief prints on metal surfaces.
Crimping die tool
It folds and crimps the sheet subproduct in accordance with the shape of the matrix and the program included in the algorithm of the machine’s operation.
Combined die tool
It uses several stamping operations in one cycle at once. Universal die tools refer to complex equipment and require careful engineering calculations when designing.
Tandem die tool
Tandem die tools are used to bend metal into various shapes using matrices.
