Whether it is sewing, knitting or weaving, textile making is dependent on precise, durable needles, carders and other fine tools – and that entails hardening and annealing the metal.
EFD Induction has sold yet another Sinac heat generator to one of the world’s leading providers of industrial tools to the textile industry. Our customer has been with us for several years and have previously purchased a large number of our heat generators.
You may not consider the textile industry as particularly dirty, but fluff and fibres representant a challenging environment to any machinery, including induction equipment. Before coming to EFD Induction, our customer frequently experienced that the induction heat generators would break down.
“It is extremely important to our customer that production runs without failures”, says Sales Manager Roman Dillmann at EFD Induction Germany. “A stop in the production line will cost thousands of Euros a day, and that is on top of the spare parts and service.”
INVESTING IN QUALITY: “Our customer saw that our high-quality Sinac heat generators would save them thousands in less downtime”, says Sales Manager Roman Dillmann.
Cotton, wool and other fibres for fabric need to be carded before the thread is spun. There are also nonwovens fabrics like felt that don’t require spinning, but which are equally dependent on good carders.
“To increase the lifetime of the carding blades, our customer hardens and anneals the cutting edges”, Roman explains.
This obviously takes some cutting-edge technology and involves two induction units for one production line. The first is where the metal is hardened by heating it to the required temperature and then cooling it rapidly. This process increases the hardness and strength of the metal but also makes it more brittle. Hence, the next stage is to anneal the metal to relieve internal stresses, soften it and make it more ductile and tough. This is done by heating it to a prescribed temperature and then allowing it to cool slowly.
“The availability of spare parts is another very important point to our customer. Previously, they had cases where they couldn’t get any only five years after the purchase of new equipment”, Roman says. “That will hot happen with EFD Induction. We are a global player and have proven our support and reliability over many years.”All in all, the customer has purchased around 40 of our heat generators and is well on their way to replacing all their induction machines with high-quality equipment from EFD Induction.
