While there are many factors that determine warm-up times, the industry standard for electric ovens has always been about 20 minutes from ambient to 400F. Our smaller size units actually warm up a bit faster than the standard and can hit 400F in 12-15 minutes. Our larger size units will be right around that 20 minute interval to 400F. Keep in mind that these standards are based on an empty oven, it is nearly impossible to give a standard value for how fast your parts will warm up (aluminum vs steel, 1/16″ material vs 1/2″ material, etc.)
