Alberto Gabika, managing director at HEROSLAM, commented: “Fastener producers face important technical challenges and we want to be their partner as a provider of top quality tooling for improving their thread rolling process. We are detecting an increasing demand for quality tooling conceived to consistently roll hard materials such us stainless steel, Grade 10.9, 12.9 steel and superalloys such as titanium or Inconel®.”

Many fastener producers perform the thread rolling operation before heat treatment and once the fastener is hardened, it needs to be rolled again to guarantee the thread is correct. This re-work process implies significant costs that fastener producers are looking to avoid. HEROSLAM offers customers a completely new range of thread rolling dies (flat, planetary and cylindrical) conceived to roll hard material fasteners in one single operation, thus avoiding re-works and secondary operations.

This new range of thread rolling tools combines top quality steels exclusively developed for HEROSLAM tools, homemade coatings such as GG coating and HEROSLAM’s expertise on thread rolling thanks to more than 70 years of experience producing thread rolling dies.The GG coating can be ordered with both flat or cylindrical dies and works extremely well in cold rolling as well as warm and hot rolling.

HEROSLAM points out that its RRO (Radiused Root Runout) features, developed for specific customer needs, also play a very important roll in achieving the necessary thread quality. RRO makes the end of the thread progressive, thus alleviating the tensions on one of the zones most prone to having problems of collapse due to the concentration of tensions. In turn, RRO positively impacts the tool’s performance, since it extends its service life. HEROSLAM offers many different types of RRO depending on the application.

Alberto Gabika adds: “Our new range of tools is helping our customers improve the quality of the fasteners they produce and achieve longer tool service life in thread rolling of hard materials. Thus, our customers are reducing their manufacturing costs by significantly reducing quality issues, avoiding rework operations, and carrying out fewer machine preps and changes, minimising machine down time.”

HEROSLAM’s new range of dies includes M2 and M42 material flat and cylindrical dies, planetary dies, knurling dies, grooving dies, ogival dies, licensed dies, nail dies, woodscrew dies, aerospace cylindrical dies, reed 2-die and 3-die cylindrical dies in J-form and R-form, control major and minor dies, expanded lead dies for warm and hot rolling, as well as special thread forms upon the customer’s request.
