We need to check if the board crack, peel, bubble, bend or not, if the design is complete or not, if the white primer surface is good or not. Sixthly, prepare the wooden skeleton with lock block and fillers, using gun nails. Seventhly, put two door skins onto the skeleton by glue, and put it into the cold press machines. One cold press machine can load 8 pieces of doors. One time pressing will cost one hour. Eighthly, clean the edge of the doors because our door skins’ sizes are bigger than the actual door sizes. Ninthly, white prime the sides of the door. Normally, we prime the four sides but if customers want to reduce the cost, we can also just prime two long sides, leaving top and bottom unsealed. Tenthly, quality inspect for the doors. Sometimes, the sides treatment may not so good, and the door surface will have some small damages during transfer, workers need to fix it up. Finally, pack doors up and store them in our warehouse. We have a 5,000 square meters warehouse, which is used to store the raw material and finished products.
