Jigsaw is really not simple

Most people are worried about the jigsaw puzzle, the puzzle has been scattered, how to ensure that the whole grain number? The wood-like knives are difficult to handle, and whether steel molds are needed or not, steel molds are expensive, and some customers even require a complete jigsaw delivery. What is its production and production?
From the printing aspect, the jigsaw only needs to finish printing the pattern, and then add varnishes, in order to prevent the processing program from grinding and printing.
Silk-stamped paperboards for making jigsaw puzzles can be made of white or ash-based boards, typically 80gsm to 1000g. Some manufacturers will select more bulky boards for easier die-cutting. However, some manufacturers prefer to use more rigid and solid board boards because the whole jigsaw is puzzled by the user. Straighten. Some of the puzzles also have a frame, and the outer frame of the bottom plate is glued with the silk screen method.
Die cutter with 0.45mm
In fact, die-cutting puzzles do not have to use steel molds. In addition to the more expensive steel molds, cutters are also required when the blades are blunt. To die-cut jigsaw puzzles, wood-like die cutters are available. The steel knife used is slightly different from the ordinary beer press box. The general beer box steel knife will use a height of 23.8mm, a width of 0.71mm, and the width of the so-called "Puzzle knife" is 0.45mm. Therefore, using laser cutting technology to make jigsaw wood samples will have higher accuracy, high repeatability, and long-lasting advantages. In general, wood that uses wider steel knives will have controllability of tool change. However, the use of wood that contains “Puzzle Knife” cannot have the suitability of tool change.
Unless it is a fine puzzle, most puzzles are divided into two straight die-cuts, one horizontal, and one knife. The pattern is as follows:

However, some of the jigsaws have a certain pattern of die-cutting, such as die-cutting figures and animal designs, and they cannot be disassembled for transverse straight die-cutting. Only the complete cutting of wood samples is required, but care should be taken to ensure that the entire layout is flat and not easily dissipated after cutting.
Die-cutting jigsaws can use hand-wrung beer machines, automatic beer machines and hydraulic presses. Among those technicians who use automatic beer machines, the version of the automatic machine is considered to be time-consuming, the speed is too fast, the pressure tonnage is lighter, and the gap between the puzzle pieces is more “bite” and the side positions are more “water level”. Instead of hand-firing machine. Automatically die-cut jigsaw puzzles, with no more than 500 grains and as little as 300 grains.
During the first die-cutting, the hand-wringing machine is the same as a normal die-cut carton, but when it is die-cut for the second time, it needs to be “carriage” in order to draw up the puzzles. Usually the technician will add it under the puzzle grain. Insert paper so that you can easily pull out the entire puzzle. However, the pressure at the bottom of the hand-wringing machine is heavier than the previous one, and the pressure is not evenly distributed. Therefore, a beer machine designed with double "flywheels" can have better results.
The best effect is to use hydraulic presses, which have better pressure tonnage and even pressure distribution with four columns. Even when the jigsaws are die-cut, the use of high and low knives for die cutting has better results, so that the jigsaw particles can be dispersed into plastic bags or the entire jigsaw puzzle can be delivered with better controllability.
When the user puts together the entire jigsaw, gently push and pull the whole jigsaw puzzle and it is not easy to be scattered. (Liu Fucheng)
