Requirements for precision die-cutting processing technology and technical points

What are the fields in which diecutting products are used, and what are the requirements for precision diecutting processing technology and technical points? Below, Chi Na Optoelectronic die-cutting Processing Factory will introduce this knowledge to you.

Requirements for diecutting products: Ensure cleanliness, no deformation, no backlog, no overflow or other defects in the product.

Die cutting product processing technology:

1. Overlap and composite two layers of double-sided tape on the circular knife machine, place the black double-sided tape on top of the white doublesided tape, and do not remove the release paper that comes with the double-sided tape.

9759彩票集团2. Use the first mold, namely the slitting knife, to directly divide and die cut the black small hole and a small frame between black and white. At the half cut, use the mold to drop the hole and transfer the waste material.

9759彩票集团3. Remove the waste between the overlapping double-sided tapes, then remove the release paper that comes with the double-sided tapes, and finally composite 75g of transparent release film with heavy release,

4. Die cut the overall outer and inner frames. Use a suction box to wash away the waste from the inner frame, and the machine to remove the waste from the outer design and roll it up.

5. Manually inspect the product for any glue overflow, peeling, poor size, and packaging before shipping.

Key points of die-cutting processing technology

9759彩票集团Since the various properties of self-adhesive label materials, such as the strength of the self-adhesive surface material, the characteristics of the adhesive, and the strength of the backing paper, have a certain impact on the diecutting quality of the label, there should be certain requirements in the selection of self-adhesive materials and label processing, and high-quality materials or corresponding die-cutting processes should be used to improve the die-cutting quality of the label. After years of practice, the author has summarized the problems encountered in work and proposed several precautions for selecting adhesive materials correctly and effectively improving die-cutting quality.

(1) Do not use die cut film materials that have been die cut from paper materials, as the blade has worn out and is not suitable for cutting film again.

(2) When die-cutting, try to reduce the die-cutting area as much as possible, especially for full page small labels, because the layout is large and there are many cutting blades, making it difficult to ensure quality.

9759彩票集团(3) During flatbed die-cutting, the backing plate should be replaced frequently, especially when processing long plates, as the cutting marks can affect the die-cutting quality of the new label.

9759彩票集团(4) Regularly check the quality of die-cutting, especially for labels with automatic labeling. To avoid large-scale quality issues. The specific inspection method is to apply a signal pen on the base paper and check the penetration of the cutting marks on the base paper.

(5) For labels with large areas and complex patterns, it is necessary to go to a professional manufacturer to make die-cutting plates, which can ensure die-cutting accuracy.

(6) To maintain the sharpness of the blade, establish a file to record the usage of each die-cutting plate, in order to replace the blade in a timely manner.

(7) Use specialized blades with small angles and high hardness to die cut thin film adhesive materials, especially PET materials.

9759彩票集团Installed products: using double-sided tape, foam tape, transfer tape, and dual stabilizing tape that can resist plasticizers to reduce fog. After segmentation and die-cutting, the products can be used on automotive parts.

9759彩票集团Noise reduction and shock absorption: Die cut products made of foam, blankets, scratch resistant textiles, etc. are applied between metal and plastic parts, between plastic parts, and between metal parts to achieve noise reduction and shock absorption.

Interior and cushioning: Various chloroprene rubber, foam, and silicone materials are precision die cut and used in decorative parts, doors, ceilings, and other areas.

Other applications: installation of car logos, high-temperature resistant spray masking paper, sealing of airbags, speaker covers, temporary protective bladder, etc.

9759彩票集团Die cutting machines are mainly used for die-cutting, creasing, and cold embossing of trademarks, paper boxes, greeting cards, and other products in the paper packaging and decoration industry. They are important equipment for post press packaging processing and forming.

9759彩票集团Die cutting processing products: Process design of double-sided adhesive for fixing circuit boards

Die cutting structure: Counting from top to bottom: The first layer is release film, the second layer is black adhesive on one side and white adhesive on the other. The black and white doublesided adhesives are tightly connected with a gap of 0.1mm, and the third layer is white PET release film tape with reading holes.

9759彩票集团Die cutting product description: The customer uses a labeling machine for automated bonding in the form of reading hole positioning.

9759彩票集团Mold selection: Due to the use of machine automated bonding for the product, the use of flat knives for production cannot guarantee the verticality of the material strip, so round knife molds are selected for production.
