How to choose a die plate according to the characteristics of the product

In die-cutting industry, die is an essential tool. A die consists of a die-cutting plate and a blade. They are generally used for stamping the desired product shape. There are many kinds of blades used in the die! Today we share with you: how to choose a die according to the characteristics of the product. To sum up, the die should be selected from three aspects of the product, in order: product precision, product output, and product material!

 

Product precision

The error of the mold itself is between plus or minus 0.05~0.2MM!

1. if the product precision is within plus or minus 0.05, three kinds of paint molds can be used: corrosion molds, engraving molds, hardware molds.

2. If the product accuracy is within plus or minus 0.1, please use two kinds of molds: wood mold and plastic mold (of course, the other three are also available, but the cost is higher).

If you can't relax the product tolerance, then don't try to use low-cost molds!

Product yield

Need to choose according to the life of the mold! If the product batch is large, easy to stamping products try to use wood and plastic mold; If the product precision is high, easy to stamping, try to use corrosion mold; If the product precision is high, can not be scrapped at once, available carving mold or metal mold production. For achieving comprehensive scrapping (because it can be modeled according to the angle you imagine).

 

If the product is complex, QDC mold can be made for multiple processes, positioning holes are convenient, and the product size accuracy can be guaranteed within plus or minus 5 silk.

 

Product material material

1. Ordinary cardboard ordinary cardboard including ordinary cardboard, corrugated paper, etc., die-cutting this kind of cardboard can use ordinary laser die (knife angle 52 °). If the die-cutting shape is complex, it is necessary to use a slightly lower blade hardness, bending performance of the die. In the die-cutting process, if you require a low die-cutting pressure, you can choose a die with a knife edge angle of 42o. Low die cutting pressure can reduce edge wear and extend the die cutting life.

 

2. Hard rubber sheet hard rubber sheet including PVC, PET, electronic board, high-density materials, gaskets, etc.. Die-cutting such materials need to have a high hardness of the die. Ordinary laser knife body hardness of 39HRC, blade hardness of 57HRC. If you want to die cutting hard rubber, you need to choose the blade hardness of 47HRC, blade hardness of 59HRC die. The smaller the blade angle, the higher the blade hardness, the better the wear resistance.

 

3. Flexible materials flexible materials including aluminum foil, web materials, soft plastics, etc.. Die cutting such materials requires the use of dies with finely ground edges. This kind of die edge surface is smooth, die cutting pressure requirement is low, easy to pass sticky materials, reduce the edge pulling and linting problems.

Understanding the Die-cutting Process in Custom Packaging

The die-cutting process is a popular manufacturing technique in the packaging industry. It involves the use of dies used to cut soft materials into various packaging designs and shapes. The ability to produce custom packaging in volume is where the true value of the die-cutting process lies. Die-cut packaging is easier, faster and more cost effective, allowing for the creation of custom packaging on a larger scale.  In this article, we'll explore the die-cutting process and its role in custom packaging.  You will also see.  ● Die-cut boxes explained in detail ● How cutting dies are made ●Die-cutting technology  ● The FEFCO corrugated packaging category  ● Finishing options that complement die-cut box design   Understanding the die-cutting process A cutting die is essentially a giant cookie cutter that is pressed into the material to form the desired shape of the package. Die cutting has come a long way from its origins in the shoe industry during the indust...

How are cutting dies made?

The development of cutting die technology and manufacturing techniques ensures the most efficient and accurate   die-cut box design . Typically, the package outline is generated by Computer-Aided Design (CAD). This digital drawing is transferred to a piece of hardwood called a template.  The most sophisticated method of drawing the design on the template is to burn it on the wood surface using a state-of-the-art laser cutter.  The introduction of the laser in this process ensures greater accuracy in drawing on the moldboard.  Cutting dies are made using metal strips called rule or steel rule. The cutting rule is shaped into shape using a rule bender, which bends, cuts and grooves the steel into the desired shape.   Multiple cutting rules can be used in the die cutting process. Each rule has its own function and purpose, depending on the complexity of the package.  Some of the most common rule options are. ● Through-cutting: Through-cutting cuts the packagin...

WHAT IS A CORRUGATED BOX?

If you work in the packaging or shipping industry, you probably work with cardboard boxes daily. Corrugated cardboard boxes are one of the core products used to package and ship products of all types around the world, so they are an integral component in several businesses and industries. While you may use them on a regular basis, you probably have never given much thought to where  corrugated boxes  come from or how they are manufactured. It is easy to forget that the boxes you depend on were once trees growing in forests spanning the globe. The process for transforming a tree into corrugated cardboard is actually quite fascinating, and it is more high-tech than you may realize. How exactly is the humble corrugated box made? We’re glad you asked! WHAT IS A CORRUGATED BOX? Corrugated cardboard is an extremely versatile material that is used to protect, display and ship virtually all types of products. It is made using three layers of strong paper known as craft paper, which m...
