In the die-cutting process There are many factors affecting the quality of die-cutting products and the effect of the process, in other aspects I do not do much discussion, mainly to talk about die-cutting mold Some personal cognition, hope to work with the die-cutting industry friends together to discuss and learn.

Die-cutting processing plantThe main molds used are:

Plank mold, rubber plate mold, aluminum plate mold, iron mold, etching mold, carving mold, metal mold, QDC mold. I'm mainly talking about carving molds and etching molds here.

Mold Manufacturers received die-cutting processing enterprises mold manufacturing drawings, on the beginning of some of the mold drawings on the request to stop evaluation and mold manufacturing process design.

There are two main aspects of mold evaluation:

One is the evaluation of the drawings: high knife, up and down knife difference, minimum spacing, blade angle request, minimum angle, surface and mold total height and accessories;

Second, manufacturing difficulty evaluation: tolerance, die-cutting composition, tool mold processing data characteristics, knife line length, minimum spacing, there is no Tan Feng knife and the required accessories.

After stopping the effective evaluation of the above elements, we can get the correct discrimination of the die-cutting processing enterprises after die-cutting processing, and be able to evaluate the mold manufacturing cycle, and help the purchase of the required accessories and other work quickly unfold.

Manufacturing process for carving molds:

Wire cutting (mainly the shape of the wire cutting and blanking hole processing): This processing takes more time, ordinary at least 2 hours or so (no drop hole of the knife mold), drop hole more knife mold to take a longer time.

CNC roughing (some knife mold manufacturers are done on top of a machine): Mainly make the knife template roughing effect can reach the corrosion process of the knife mold, but the processing effect is better, can be machined to the knife line width of 0. 5mm, so that the sharpness of the rear finishing blade and blade side of the brightness is better. This roughing process also maximizes the application and maintenance of mold processing equipment.

CNCPrecision Die CuttingProcessing: Mainly on the mold stop the last blade molding processing, so that the knife mold blade sharp, bright appearance.

Mold set: Carving knife mold ordinary will be accompanied by an aluminum plate, to reach the total height of the mold 23.8mm to meet the die-cutting processing enterprises die-cutting machine mold height request. Some special structures of the mold to be assembled into a lot of accessories (such as internal withdrawal carving tool mold, top material carving knife mold, blowing carving knife mold, suction carving tool mold).

Inspection: will set up a good mold scrap stop inspection. Such as: Mold total height, mold can be divided with drawings, blade can be sharp, can have fake blade, light brightness, burr, batch, up and down, knife height, blade angle, product name, material number and so on.

The above is the manufacturing process of carved knife mold. Perhaps Die-cutting engineers do not need to understand this, but if you understand, you will be in the die-cutting process design process, understand whether the mold can reach your product processing request, mold manufacturing process of the difficulties in where, the time to use is a few, your mold supplier can do the results you want.

In the process of mold design and manufacturing process, the most central part is how to design the blade angle, find the most suitable blade angle ability to maximize the value of the knife mold. Cut what information, with what blade angle, to what effect is very important, blade angle is smaller, blade sharper more prone to blunt.

Cut PE or toughness of the information:

Blade to Sharp, at the same time to pay attention to the blade angle enhancement, in the mold manufacturing blade side of the brightness is particularly important, must be lubrication. When making blade design, we should pay attention to the equilibrium of the resistance size and internal and external resistance of the balanced knife die blade about the data to be processed. Knife mold blade angle can deal with die-cutting products deformation, indentation, back adhesion, cutting edge is not uniform and other problems of the attack.

Cutting non-substrate double-sided adhesive:

Blade angle is: the product side of the small angle, non-product side of the large angle, at the same time the side of the knife mold must be bright, so as to reduce the product by the knife mold extrusion deformation and indentation generation. The outer side of the large angle to provide assistance for waste disposal, but also let the life of the knife mold to be guaranteed.

Double-sided adhesive for cutting non-woven substrates:

Knife mold blade To do two angles, blade front small angle, back is enhanced large angle, so that the blade is particularly sharp, but also let the strength of the blade to enhance. Non-woven substrate double-sided adhesive will have some fiber in it, so the request for the sharp level of the knife die blade will be higher.

To cut PET substrates.Double-sided adhesive die-cutting：

Mainly look at the thickness and viscosity of the glue to resolution blade angle, thick words to pay attention to the blade angle on the product extrusion problem, at the same time to pay attention to the blade strength maintenance.

Carving knife mold in the clean and waste has a very good performance, different data and the process of waste cleaning methods are different.

Die-cutting process is generally divided into half-cut and full-cut. The effect of semi-get used need reaching the Qing waste is conditional, it must be from the heavy off-film or paper side of the Che Qing waste, as long as this can be cleared. All Che Qing waste is not only to see the viscosity and thickness of die-cutting processing data, but also to see the material.

The manufacturing process of cleaning die is very important.

Do not grasp the manufacturing process will be presented: the front of the 1000 mold cleaning effect can also be, but the more to the back of the waste of the situation. How to do it is the best? This is mainly to see the experience and talent of the knife mold manufacturer, the design of a good blade angle can make the quality of the mold and life both improved.

The factors that affect the quality of the knife mold have the following aspects (mainly for the carving tool mold, etching knife mold):

Knife Mold Steel: The quality of the steel used in the knife mold has a direct impact on the mass of the knife mold. Good steel is different in steel and toughness, and the knife die is used to SK-5 this steel.
Processing equipment: Carving knife mold and etching knife mold is mainly CNC processing out, equipment accuracy and speed and equipment Summer Palace is particularly important.

Technical strength: If the first two links are done, knife mold design and manufacturing of technical strength is good, the quality of the knife mold will improve a lot.
Quality control: high-quality knife mold is a severe stop quality control consumption out. Knife mold in the quality phase of the detection of bad, can only be scrapped, there is no room for repair.
