TEMSA appears once again in the Fastener + Fixing Magazine. This time the acquisition of PLUSDUR has called the attention of the popular magazine and has published an article for its issue 94 July, 2015.
Fastener + Fixing Magazine is a world leader in the fasteners industry and published the most relevant news of the market, and so has decided to publish the acquisition of PLUSDUR by TEMSA in the special issue of Dies + punches, since it means the origin of a key global player in the cold formed fastener industry.
The resulting group enjoys of significant synergies and covers the whole range of products for the cold forming industry: from dies to punches and ejectors, either rounded or non-rounded internal and external profiles, thanks to the flexibility of PLUSDUR and the powerful erosion and CNC grinding departments of TEMSA.
TEMSA has published a new catalogue for open dies due to the high demand observed lately, both for the manufacture and the design of the tools.
The main goal of this catalogue is basically to broaden the knowledge of this product among the current partners of TEMSA. On the other hand it tries to inspire and encourage those ones who currently do not have enough know-how in this technology so they ask TEMSA for help if they feel this drawback is insurmountable in order to improve their product range.
TEMSA has significantly increased the production of open dies, since the segments of TEMSA are independent and interchangeable between each other and this is a plus for the technicians.
This catalogue was first introduced at the Fastener Fair 2015 in Stuttgart and it was very well received. The open dies are going to be considered, together with the popular catalogue of TEMSA Extrusion dies the flagship of the cold forming tooling by TEMSA.
In Hexalobular dies, also called Torx-type dies, we have sometimes found tool designs where the material could not completely fill the calibrating zone down to the desired depth and, consequently, some remained out of it.
When the reduction percentage of the wire in the calibrating zone is equal or higher than 30%, then the wire has a natural tendency to expand itself lengthswise just like a cork in a bottle, meaning that it tends to spring out.
As it is seen in the drawing, this problem can occur when the reduction in the die is not guided. Therefore, if we add a small guide of about 1 mm depth before the hexalobular reduction, the material will not expand lengthwise and thanks to the crosswise pressure, we will force it to enter into the calibrating zone down to the desired depth.
For this kind of dies, having a reduction and an hexalobular profile, TEMSA recommends the TEM4F quality, as this is the carbide quality having the best combination of resilience and hardness required for this application.
