How to control the deformation in the processing of polyoxymethylene board
Yes, it should be annealed before processing. The annealing step is as follows: POM product annealing step: 1. Plug in the power of the electric oven; 2. Turn on the power switch; 3. Adjust the temperature to160℃; 4. After reaching the set temperature, put the product into the furnace; 5. The holding time increases with the increase of the thickness of the workpiece. See the process documents of related products for details. When the process engineer calculates the product heat preservation time, it is 30 minutes plus the thickness of the workpiece (measured at the thickest part of the workpiece wall, in mm) 1 MM multiplied by 5 minutes. If it is less than 1MM, it is calculated as1mm. For example, the thickness of the workpiece is 5.5MM, and the holding time is 30+6 * 5 = 60 minutes. And so on. 6. Open the oven door, take out the product and cool it to room temperature.
