Leakage in a hot-runner system or manifold due to cold starts or manifold system wear reportedly can be eliminated with Magna Spring, a new spring assembly from Polymer Cleaning Technology Inc., Hillsborough, N.J. Magna Spring is designed to replace conventional back spacers on any hot-runner system. As the manifold system begins to heat, the two-piece, retrofittable spring assembly on the back plate creates thousands of pounds of force, keeping the system sealed.
