The structure and form of post-press die cutting equipment

Post- press die-cutting is one of the important production processes for printing and packaging products. The factor that plays a major role in die-cutting production efficiency, production cost and product quality is die-cutting equipment. Enterprises should correctly understand the characteristics of die-cutting production equipment, and purchase suitable die-cutting equipment according to the actual production conditions and development needs of the factory.

According to the structure and characteristics of the product, the die-cutting production process should be different. Therefore, the die-cutting machine also has various structures and forms.

The plate of the horizontal flat-pressing die-cutting machine is parallel with the pressing working face, and the lower pressing mechanism completes die-cutting by a regular upward-shaped movement. The machine has excellent performance, convenient operation and high degree of automation. Because the machine's separation and closing strokes are short and the speed is fast, the machine is also equipped with an automatic stripping device, which can better meet the requirements of continuous automatic paper feeding and high speed die cutting work. Nowadays, the horizontal flat-press automatic die-cutting machine with international advanced level, such as Bobst SP series die-cutting machine, can reach 12,000 sheets per hour and the die-cutting precision is about 0.05 mm. The horizontal flat-press automatic die-cutting machine produced in China can reach 7000~8000 sheets per hour, and the die-cutting precision is between 0.1~0.15mm. For example, the price of MK series die-cutting machine of Tianjin Changrong Printing Equipment Co., Ltd. Only about 1/3 of similar foreign products, high cost performance, can complete the die cutting of most fine products. Whether it is imported equipment or domestic equipment, the paper feeding size of the equipment is not less than 1020 mm × 720 mm.

The die of the circular die-cutting machine is mounted on the drum, and the pressing component is also in the shape of a drum. It is a complete "line-to-line" pressure contact, the pressure is sufficient and uniform, and the die cutting with high precision and high speed can be obtained. The effect, its production efficiency and quality are at the top of various die-cutting machines. However, the machine has a large investment in production process, high plate making cost, and difficulty in loading the plate. The current application market has certain limitations. Therefore, only a relatively fixed and large-volume product die-cutting can make the production cost and product quality better. Good balance. Taking cigarette packets as an example, enterprises with an annual production capacity of more than 200,000 large boxes can consider the procurement of such equipment. The uncontrolled rate of products will be greatly reduced, and the production efficiency will be significantly improved.

When purchasing a die-cutting machine, the printing and packaging company should consider the product structure, machine model, performance, function, specifications, quantity, price positioning, equipment transportation mode, installation and operation technology training. If you need to purchase more than one machine of the same model, you should first order one for trial use, and determine whether to purchase in bulk according to the usage. Through step-by-step procurement activities, the blindness of equipment procurement can be better avoided, and the management quality and efficiency of the enterprise can be improved.
