What are the advantages of selecting precision engraving machine for processing carton packaging die?

When processing the die for carton packaging, the choice of precision engraving machine has unique advantages compared with traditional processing methods (such as laser cutting and milling machine processing), especially in accuracy, efficiency and material adaptability. The following is a detailed analysis of its core advantages:

1, the machining accuracy is higher, and the precision requirements of the cutter die are met.

The die for carton packaging requires extremely high precision (especially the folding line and incision position), which directly affects the fit and aesthetics of carton after molding. The advantages of precision engraving machine are as follows:

High positioning accuracy: High-precision guide rails (such as ball screws and linear guide rails) and servo motors are used to drive, and the repeated positioning error can be controlled within ±0.01mm, which is much lower than that of traditional laser cutting (±0.1mm) or milling machine (±0.05mm), and it can accurately engrave the cutting edge angle, crease line depth and other details of the die.

The cutting edge is processed more finely: the "blade" of the knife die (such as the blade of a curved knife and a straight knife) needs to be sharp and have the same angle. The precision engraving machine can chamfer the cutting edge below 0.1mm through the alloy cutter (such as a tungsten steel cutter) rotating at high speed, so as to avoid the problems of carbonization and curling of the cutting edge caused by thermal effect in traditional laser cutting, and ensure that the edge is smooth and burr-free when cutting the carton.

High reducibility of complex patterns: For knife dies with special-shaped holes and fine patterns (such as hollowed-out patterns packed in gift boxes), the precision engraving machine can directly import and process the CAD drawings, which can restore the design details 1:1, and avoid the accumulated errors of manual drawing or milling machine processing.

Second, the material has strong adaptability and is compatible with a variety of knife die substrates.

The base materials of carton knife die are diverse (such as plywood, density board, acrylic, metal sheet, etc.), and the precision engraving machine can be flexibly adapted:

Efficient processing of nonmetallic substrate: aiming at the commonly used plywood die (thickness 3-18mm), the engraving machine can realize rapid cutting and grooving (such as V-shaped groove of crease line) by adjusting the cutter speed (8000-30000rpm) and feed speed, and it will not cause wood edge blackening and deformation due to high temperature like laser cutting.

Machining ability of metal die: For metal die with higher hardness (such as thin steel plate and aluminum plate), precision engraving machine with cemented carbide cutter or diamond cutter can directly engrave the cutting edge and positioning hole without additional process (traditional metal die needs to be stamped first and then polished, and the process is complicated).

Compatibility of multi-layer composite substrates: some cutter dies adopt the composite structure of "wood board+steel sheet", and the precision engraving machine can complete the processing of different materials at one time by setting cutter parameters in layers (such as high-speed cutting of wood board and low-speed milling of steel sheet), thus reducing the time cost of changing equipment.

Third, the processing efficiency is improved and the production cycle is shortened.

High-speed cutting capacity: The spindle speed of the precision engraving machine can reach 15,000-40,000 rpm. With the automatic feeding system, the processing time can be shortened to less than 30 minutes for the 1.2m×2.4m standard tool template (traditional milling machine takes 1-2 hours, and the laser cutting speed is limited due to heat).

Stability of batch processing: it supports batch import of tool die drawings, and realizes multi-plate continuous processing through automatic positioning (such as CCD visual positioning system), and the error consistency of each tool die is high, avoiding individual differences caused by manual operation.

Process integration: It can complete multiple processes such as "cutting edge, carving crease line, drilling locating hole" at the same time, without transferring workpieces between different equipments like traditional processes, thus reducing the handling and waiting time.

Fourth, reduce material waste and production cost.

High-precision typesetting optimization: the CAD/CAM software supporting the precision engraving machine supports intelligent typesetting, and the material utilization rate can be increased by 10%-20% by compactly arranging multiple knife patterns on a plate (traditional manual typesetting or laser cutting needs to reserve a larger spacing due to precision limitation).

Low tool loss: Compared with the high energy consumption of laser cutting (high electricity cost) and the rapid tool wear of milling machine (especially for processing hard materials), the alloy tool life of precision engraving machine is longer (a single tool can process hundreds of plates), and the energy consumption is only 1/3-1/2 of that of laser equipment.

Low rejection rate: due to high machining accuracy and small thermal influence (no burning edge of laser cutting and edge collapse of milling machine), the qualified rate of finished knife die can reach over 99%, reducing rework waste caused by dimensional deviation.

Five, flexible operation, to meet the needs of small batch and personalized.

Carton packaging knives often need to be customized according to customer needs (such as holiday gift boxes and special-shaped packaging), and small-batch and multi-batch orders account for a high proportion. The flexibility of precision engraving machine is embodied in:

Rapid production change: from design drawings to processing completion, only parameters need to be imported through software (no need to adjust the mechanical structure), and the production change time can be controlled within 10 minutes, which is far better than the traditional "2-3 hours of machine re-adjustment" for mold processing.

Support complex special-shaped machining: For non-standard cutter dies (such as circles, arcs and wavy edges), the engraving machine can realize curve cutting through 3D path planning, while laser cutting is prone to precision deviation when dealing with large curvature radians, and it is difficult for milling machines to process complex curves.

Visual operation: The supporting software can simulation of machining the path in real time and preview the effect of the die in advance, which is convenient to correct the design defects before machining and reduce the cost of trial and error.

Sixth, prolong the service life of the knife die.

The durability of the die depends on the quality of the cutting edge and the integrity of the substrate;

The precision engraving machine avoids the internal stress of the substrate (such as plywood) caused by thermal deformation by "cold working" (no high temperature), and reduces the risk of cracking in the use of the knife die.

The cutting edge is smooth and burr-free, which can reduce the friction when cutting the carton and prolong the service life of the knife die (under the same material, the durability of the precision carving knife die is 20%-30% higher than that of the laser cutting knife die).

summary

The core advantages of precision engraving machine in cutting die processing of carton packaging can be summarized as "high precision, high efficiency, high adaptability and low cost", especially suitable for scenes with high precision of cutting die, small order batch and strong personalization (such as gift boxes, cosmetics boxes, food packaging boxes, etc.). With the improvement of the packaging industry's requirements for appearance and molding accuracy, precision engraving machine has become the mainstream equipment for knife mold processing, which can help enterprises to shorten the production cycle and enhance the competitiveness of products.
