This compression spring, used in an automotive transmission hose, is another great example of our spring coiling and grinding expertise. Through our advanced CNC coiling technology and successful process control, we are able to meet the application’s exacting tolerances.
We manufacture and deliver 200,000 springs approximately every two weeks as part of this manufacturing customer’s Just In Time (JIT) delivery requirement.
The compression spring supports the thin walls of an automotive transmission hose. The spring’s tolerances are tight so that the spring fits in the center of the rubber mold. If the free length of the spring or outside diameter of any coil in the spring is out of tolerance, the spring will protrude the rubber wall. The ends of the spring are ground square so that the hose has a flat, square surface. The springs are zinc phosphate coated so that the rubber adheres to the springs. We must manufacture and deliver on time millions of these springs each year and not have 1 bad spring.
We use advanced CNC coiling machines with in-line digital inspection cameras and sorters. These machines are incredibly fast and accurate. The camera and sorter inspect 100% of the parts without any time or labor added to the process. After each spring is coiled, inspected and sorted, it falls into a conveyor oven for even and accurate stress relieving. The springs are then loaded into our CNC spring grinder where the ends are ground square. We monitor the free length and squareness during the grinding process. We send the springs out to an approved vendor for zinc phosphate plating. We inspect the parts after plating and package them in a standard quantity per plastic lined box. Every shipment can be traced back to its material heat number.
The combination of our high-technology equipment, strong process control, and skilled employees that care allow us to reliably deliver 6,000,000 springs per year without problems.
We specialize in supplying OEMs their requirements of medium to high quantities of springs and wire forms. If you are having problems with your current supplier of custom compression springs, and need someone who is reliable, credible, and willing to work for your specific needs, contact Master Spring and Wire Form. Our standard lead time for most compression springs is 1 to 2 weeks.
