Commonly used Die cutting materials
Tape types
Electronic tape, medical tape, 3M double-sided tape, such as: 9471,9009,9448,55256, etc. TESA based rubber, such as: 4972, 5194, 68634, etc. NITTO based rubber, such as: 5302A, 5713,5000 NS, etc. General glue is divided into organic glue and inorganic glue two categories, the above just introduced a variety of rubber production companies several products, led by 3M rubber production companies for the world's various industrial products developed hundreds of kinds of glue, each type of glue has a property and use. Double-sided adhesive tape can be divided into two kinds in terms of existence form, one is no substrate, the other is a substrate. No substrate is the glue directly coated on the release paper, generally very thin, there is a lot of extension, flexibility, die cutting processing is easy to stick back, deformation. For example, 3M468, 467.There is a substrate is in a layer of PET film, cotton paper or nonwoven cloth two-sided coating glue. PET base material products are easier to process, cotton paper and nonwoven fabric base material processing difficulty is higher, the edge is easy to see wool, easy to deformation, poor elasticity. There are two kinds of glue classification commonly contacted, one is acrylic glue, widely used to bond metal, plastic, glass and other objects with high surface strength materials; One is silicone rubber, this kind of adhesive paper can be directly bonded with rubber, silicone material, without additional treatment. Glue is different application of the object is also different, the current market application of the adhesive paper made of acrylic glue on the other side of the silicone rubber, so that you can stick to the SIDE of the PC, the side of the silicone key. And if you use acrylic glue to adhere to the silica gel key, you need to use a special potion to deal with the silica gel key material, change its surface strength and then stick. Paper types Paper is one of the indispensable materials in the process of die-cutting production, it can effectively cover the separated double-sided adhesive, so that the mold will not be glued while cutting. General paper is also divided into two sides, one side is rough, one side is fine, the rough surface viscosity is strong, the detailed surface viscosity is weak, generally let the weak adhesion surface contact glue, can effectively control the glue. Release paper according to whether or not coated plastic is divided into: coated paper and non-coated paper. Coated paper is divided into: single plastic paper and double plastic paper. Non-coated paper is divided into: Glasin, CCK. There are many types of paper: G120, G540, 80G single-sided glazing, beautiful paper (a soft paper with adhesive), A550, A770, 74 grams of blue glazing, etc., all kinds of paper also have different auxiliary uses, according to the design of the product process to determine. Glassine paper (GLASSINE/SCK0): The base paper is dense, uniform and has good internal strength and light transmittance. It is a common material for making bar code labels, adhesive tapes or sticky industrial products, especially suitable for rotary and flat die cutting Coated paper (PEK): Kraft paper with PE film, competitive price, combined with the characteristics of Gerracine paper and CCK paper, smooth, not easy to deform, good toughness, punch resistance, can withstand high strength mechanical pressure, is an ideal industrial paper. Coated paper is suitable for advertising materials, adhesive, electronic die-cutting, etc.
Screen types Silk screen is a black material with a lot of weaving. It's soft and as comfortable as cloth. Generally divided into two types of waterproof and dustproof, model B090HY, B010, and some wire mesh, etc. PET types These materials are plastic products, but also have different two-sided characteristics, strong sticky surface and weak sticky surface. The use of PET is similar to that of paper, and the material is selected according to the product. Foam types It is a kind of black material as soft as cotton. The thickness of foam is different according to the product model. The foam is divided into organic cotton and inorganic cotton. Foam is widely used, mainly used in mobile phones, computers and all electronic products with screen, with the effect of shock, shock absorption and other practical significance. 
Protective film types This material is mainly used for screen protection and shell protection of a material. In addition to the production of products, protective film can also be used as an auxiliary material in production, its use is quite extensive. Protective film, its material is PET, PE, PVC, PET protective film is often double layer, protective film with release film, good quality, adhesive layer coating uniform, adhesive layer cleanliness is high, easy to process, after cutting will not have too much change. The processing environment must be of high cleanliness. Such as:3M76991, 3M2T01, NITTO RP301 and other protective film. The protective film of PE material is also like the protective film of PET, but most of it is a single layer, which must be bonded with the auxiliary material before punching and then processed. For example: NITTO RP6030, R100, etc., the phenomenon of shrinkage and extension should be avoided during the bonding. In order to reduce the damage caused by this phenomenon, it is recommended to set the small size as the marking direction in typesetting.
