During the slitting process of PET film, many companies will encounter a headache: obvious white edges or static marks appear on the edge of the film after slitting. This not only affects the appearance of the product, but also directly leads to a surge in scrap rates in high-end application scenarios such as optical films and electronic protective films. So, how exactly is the white edge produced? How to effectively eliminate it? This article provides you with a complete set

During the use of the ribbon slitting machine, the unstable tension is a relatively common fault. Unstable tension will directly lead to uneven edges, wrinkles, and even broken ribbons in the slitted ribbon, seriously affecting product quality and production efficiency. So, when encountering the tension of the ribbon slitting machine, how should it be adjusted? Let's explain in detail from two aspects: cause analysis and solutions. 1. Common manifestations of tension instabil

In the processing of PET film, uneven winding end faces after slitting are a common and headache. Uneven end faces not only affect the appearance of the product, but also cause downstream customers to deviate, wrinkle or even break the film during unwinding, which directly affects the product qualification rate and customer satisfaction. So, how to effectively solve this problem? The following three tricks have been proven in practice and can significantly improve the neatnes

In the production process of hot stamping foil, the quality of the cut edge in the slitting process directly affects the subsequent hot stamping effect and material utilization. Many operators encounter a headache – uneven cutting edges, many burrs, and even wavy edges. This not only causes material waste, but may also lead to poor foil flow and incomplete patterns during hot stamping. In fact, 90% of the problem of uneven cutting edges is rooted in inaccurate knife alignment

In the post-processing of high value-added film materials such as hot stamping foil, electrochemical aluminum, laser film, etc., the winding quality of the slitting machine directly determines the yield and the efficiency of downstream printing hot stamping. However, winding deviation (commonly known as "uneven winding" and "tower wheel winding") is one of the most common pain points in the industry. Once there is a serpentine swing or uneven end face, it can lead to material

In the production and slitting process of hot stamping foil, static electricity problems have always been one of the common faults that plague enterprises. Excessive static electricity can lead to foil adhesion, uneven rewinding, unwinding and slipping, and even electric shock or fire hazards for operators. This paper will focus on the two core treatment schemes of grounding system optimization and static roller selection and layout, focusing on the causes of static electrici

Uneven winding is one of the most common equipment failures during the slitting process of ribbons (thermal transfer ribbons). At best, it will affect the appearance of the product, and at best, it will lead to ribbon wrinkles, breakage, or even scrapping of the entire roll. In this case, it is obviously unrealistic to disassemble and assemble for most of the day every time. Here are several proven quick tuning methods to help you solve problems in the shortest possible time.

Abstract:In the process of ribbon slitting, edge cutting burrs are a common problem that affects product quality and subsequent printing results. Starting from the causes of burrs, this paper systematically analyzes the influencing factors such as tool status, slitting parameters, material characteristics and equipment accuracy, and puts forward corresponding elimination measures and process optimization schemes to provide reference for the quality control of ribbon manufactu

In the production process of ribbon (heat transfer ribbon), the slitting machine is one of the core equipment. However, many companies face a common pain point: changing specifications is too slow. Every time the width, length or core specification of the ribbon is changed, the machine is often stopped for half an hour or more, which seriously reduces the overall output efficiency and increases the labor intensity of operators. So, how to solve this problem? The following giv

The solar film slitting machine is a key equipment in the processing of materials such as optical film, automotive film, and architectural film. After long-term operation of the equipment, various failures will inevitably occur, affecting production efficiency and product quality. This article summarizes common fault phenomena, causes and troubleshooting methods, and provides systematic maintenance suggestions to help operators quickly solve problems and extend the life of eq

Abstract As two important polymer film materials, lithium battery separator and PET film have certain similarities in the slitting process, but the difference in material properties also puts forward different requirements for slitting equipment. This paper systematically analyzes the versatility and limitations of the two in slitting machine equipment from the perspectives of material characteristics, slitting principle, equipment structure and process parameters, and provid

In industries such as packaging and printing, textile decoration, and stationery manufacturing, hot stamping foil (commonly known as electrochemical aluminum) is a common surface decoration material. It attaches the metallic luster or colored luster to the surface of the substrate through hot press transfer, enhancing the grade and visual appeal of the product. The process of hot stamping foil from large coil master roll to finished small roll is inseparable from a key equipm

Abstract As the global thermal transfer printing market (barcodes, labels, bills, etc.) continues to expand, the demand for Thermal Transfer Ribbon (TTR), which is its core consumable, is increasing. As the core equipment for processing wide and large coil raw materials into precision finished rolls, the ribbon slitting machine is undergoing a profound transformation from traditional semi-automatic machinery to high-precision, high-efficiency, and fully intelligent equipment.

Abstract: Ribbon (Thermal Transfer Ribbon) In the production process, the slitting process is a key part of determining the quality of the finished product. With the development of ribbon coating to high sensitivity, high heat resistance and thinness, the untimely disposal of waste (edge filament) and fine dust pollution generated during the slitting process have become the main bottlenecks affecting production efficiency and product appearance quality. This paper discusses t

Introduction The slitting of solar film (thermal insulation film, automotive film, construction film) is a key link in the production process, and its precision directly determines the quality of the finished product. However, slitting machines are high-speed rotating equipment, integrating sharp circular knives, pneumatic systems, hydraulic systems, and electrical control systems, and there are potential risks such as mechanical injury, electric shock, and fire during operat
