Precision Econowind Products
Thin Film Material
A privately owned American company that manufactures custom coils for the loudspeaker, medical, aerospace, and many other industries.
Thin Film Material
At Precision Econowind LLC, we supply thin film material, for both coil forms and reinforcing collars, for customers who wish to manufacture voice coils or other electrical coils on-site at their facility.
Thin film material is coated on one side with our proprietary high temperature adhesive capable of withstanding temperatures over 500°F. Many customers have found that in direct comparison with other electrical coils, this adhesive has been the difference in preventing coil failure especially in voice coil applications. The high temperature adhesive not only extends the life of the coil, it allows product designers more freedom in coil placement in space constrained situations.
