Ming Tai Industrial developed constant force spring for 250℃ high temperature operation environment

High temperature is a technological bottleneck to steel strip spring applications.  It requires extremely high technique and spring design and process technology distinguished from general springs to keep its constant force under high temperature over long period of time.  Therefore, Ming Tai Industrial developed the constant force spring keeping in constant force under high operational temperature over long period of time for the use of a fireplace manufacturer. 

The fireplace manufacturing company in North America inquired Ming Tai if there is special material available for making the constant force spring under 250℃ over long term.  They would like to apply it on the resolution to the positioning and effort-saving resolution for the constant force spring installed on top and bottom sliding door of fireplace.  With careful evaluation, Ming Tai has completed many tension and stress tests, and developed a special production process, that is using most common stainless steel AISI 301(DIN 1.4310) manufacture high-temperature resistible constant force spring to meet the customer’s requirements.

Ming Tai Industrial not only designs the constant force spring applied to the high-temperature resistible fireplace for the customer, we also suggest the customer to select aluminum extrusion to replace the material which the customer originally intended to use for spring drum.  It has successfully saved remarkable costs.  Different sliding doors of fireplaces need to match constant force springing with different constant force to exert.  Therefore, Ming Tai Industrial marks the constant force value on the top of spring allowing the customer to use the spring correctly under several tension combinations.

From the application design, process development, output drum material selection, drum assembly to marking, Ming Tai Industrial provides not only the steel spring products, but also the integrated resolutions. 

With experiences over 45 years, Ming Tai is capable of processing and design for all kinds of steel springs and assembly and mounting service.  We sincerely suggest you to consult our RD engineer at the beginning of product design phase, and allow Ming Tai find the best resolution for your product that satisfy your requirements.
