What are the characteristics of high-precision engraving machine used in cutting die processing in packaging industry?
Have finished thinking
High-precision engraving machine is well adapted to the requirements of precision, diversity and efficiency of packaging products by virtue of its technical characteristics in the cutting die processing of packaging industry. The specific characteristics are as follows:
1. The processing precision is extremely high, and the packaging molding quality is guaranteed.
The precision of packaging die directly determines the forming effect of packaging box (such as dimensional tolerance, notch flatness, splicing tightness, etc.). The core advantages of high-precision engraving machine are:
Positioning accuracy: usually up to ±0.01~0.05mm, it can accurately control the position of the cutting edge of the knife die, and ensure that there is no dislocation or skew after the packaging box is folded (such as splicing the heaven and earth covers of the gift box and matching the tongue of the folding carton with the slot).
Consistency of cutting edge: through stable spindle speed (usually 10,000 ~ 30,000 r/min) and precise tool path planning, the depth and angle of the cutting edge of the die are ensured to be uniform, and the cut is smooth and burr-free when cutting materials (such as cardboard, corrugated paper and plastic film), so as to avoid the appearance of the package from being affected or cracked due to "burrs".
2. Adapting to the complex die structure to meet the requirements of personalized packaging.
Modern packaging design pays more and more attention to personalization (such as special-shaped box, window structure, embossed texture, etc.), and high-precision engraving machine can easily deal with complex knife die processing;
Complex pattern processing: support 2D/3D graphics import (such as CAD and AI format files), and can accurately carve special-shaped cutting edges (such as circles, waves and irregular curves), multi-layer stepped knife dies (for layered cutting of thick materials), half-piercing knives (for folding and creasing instead of cutting), etc., to meet the special structural requirements of window boxes, special-shaped gift boxes and three-dimensional packaging.
High degree of detail reduction: For the subtle features on the packaging die (such as 0.5mm wide slit and small positioning hole), the engraving machine can accurately engrave, ensuring that there is no "missing cut" and "over cut" during cutting, and ensuring the stability of complex structures (such as micro crease lines of precision folding boxes).
3. The material has strong adaptability, covering the mainstream material of packaging knife die.
The materials of the packaging knife die are various (selected according to the hardness of the packaging material), and the high-precision engraving machine can be compatible with various substrates:
Wooden knife die: it is often used in paper packaging (such as corrugated boxes). The engraving machine can cut multi-layer plywood efficiently, and at the same time ensure the accuracy of the cutting edge groove to avoid the "off-position" of the wooden knife die caused by processing errors.
Metal die (steel die, aluminum die): used for hard materials (such as cardboard, plastic, leather). The engraving machine can engrave a high-precision cutting edge on the metal surface through a high-hardness cutter (such as a tungsten steel cutter) and a rigid spindle, and the wear resistance of the processed cutting edge is high, thus prolonging the service life of the die (the life of the metal die can reach 10-50 times that of the wooden die).
Composite knife die: such as "steel-wood composite knife die" (wood substrate+metal cutting edge), the engraving machine can synchronously process the splicing parts of different materials to ensure the combination accuracy.
4, the processing efficiency is high, and the production cycle is shortened.
The packaging industry often faces the demand of "small batch, multi-batch" orders, and the high-precision engraving machine improves the efficiency by the following ways:
High-speed machining: Compared with traditional manual engraving or wire cutting, the high-speed spindle of the engraving machine and the optimized path algorithm can shorten the processing time of a single set of knife dies by more than 50% (for example, a set of medium-complexity carton knife dies takes 4-6 hours for traditional machining and only 1-2 hours for the engraving machine).
Batch automation: support multi-station continuous processing, and cooperate with automatic loading and unloading system to realize "unattended" production; At the same time, through software batch typesetting (such as nesting multiple small-sized knife dies on a substrate), material waste is reduced and material utilization rate is improved (up to more than 90%).
5. Strong flexibility and quick response to design iteration.
Packaging design has fast iteration (such as holiday customized packaging and brand change), and the "digital processing" feature of high-precision engraving machine can be quickly adapted;
No need to open the mold: directly drive the processing through design documents (such as CAD drawings), and only need to adjust the software parameters when modifying the design, without re-making the master mold, thus greatly shortening the proofing cycle (from the traditional 3-5 days to 1 day).
Adjustable parameters: according to the material thickness (such as 1mm cardboard vs 5mm corrugated paper), the cutting depth and speed can be adjusted flexibly, without changing equipment, thus reducing the cost of changing production.
6. prolong the service life of the die and reduce the comprehensive cost.
High-precision engraving machine reduces die loss through "precision machining";
During machining, the contact between the cutter and the substrate is stable, so as to avoid the cutting edge cracking and the deformation of the substrate caused by vibration or error, and prolong the service life of the cutter die (especially the metal cutter die can be reused for thousands of times).
Reduce the "waste mold" rate: the traditional machining may lead to the scrap of the knife mold due to the lack of precision, while the machining qualification rate of the engraving machine can reach over 99%, reducing the waste of materials and the cost of rework.
summary
Through the characteristics of "high precision, high flexibility and high efficiency", the high-precision engraving machine perfectly meets the needs of the packaging industry for "precision, personalization and quick response" of the knife die, which not only improves the appearance and quality of the packaging products, but also helps enterprises to take the advantage in the market competition of small batch customization and rapid iteration.
