For manual waste stripping, which is inefficient, printing factories require 3-4 workers. As a result, in order to improve efficiency, most printing plants will be outfitted with relevant automation machines to address this issue. There are currently professional offline waste stripping machines on the market in addition to die-cutting machines with waste stripping functions, so how should the factory choose between these two machines?
The working principle of a die cutting machine with a waste stripping function:
At the moment, the waste stripping function of die-cutting equipment available on the market consists primarily of full stripping and semi-stripping. After die-cutting the product, some unnecessary waste paper must be removed from the sheets, and only the finished products are needed. Semi-stripping refers to the incompletion of the waste stripping process, and some locations require manual secondary waste removal.
The stripping molds are indispensable in the die-cutting machine with waste stripping function. The general principle is as follows: the material first enters the die-cutting section for die-cutting, and then enters the stripping section. With the help of stripping molds, the machine removes waste paper from the edge of the sheets and inside the sheets before sending out the finished product.
The working principle of an offline stripping machine:
The sheets will be placed under the press bars of the offline stripping machine using simple positioning settings, the finished product will be pushed from the entire sheets, and the products will be automatically delivered and palletized. The paper scraps generated during the stripping process will fall into the waste discharge channel.
Compare the characteristics of the two machines
To help the printing factory make a better decision after understanding the basic operating principle, let’s compare the characteristics of the two machines:
Die-cutting machine stripping characteristics
1. A one-to-one stripping mold based on the product is required.
The stripping mold and die-cut mold must be used in tandem. The whole unit of stripping mold set includes a die mold, an upper stripping mold, a lower stripping mold, and a front stripping mold. A set of ordinary stripping molds on the market costs 1,000~5,000 USD, and some professional stripping molds cost more than 10,000 USD.
2. Debugging the stripping section takes a long time.
It takes several hours to install and debug the stripping section, and it also needs to cooperate with the die-cutting function so that the die-cutting can be carried out more smoothly.
3. Exorbitant machine price
A die-cutting machine with a waste stripping section is significantly more expensive than a standard die-cutting machine. A Standard BOBOST die-cutting machine costs between $120,000 and $180,000 USD, while one with stripping section costs at least $250,000 USD.
4. Better suited for large orders
Because of the need to customize the stripping mold, it will be in a relatively stable state after commissioning, and it will be more suitable for printing factories with long-term orders, in order to reduce production costs as much as possible.
Waste stripping machine characteristics
1. There is no need to create a stripping mold
The waste stripping machine does not require the creation of a stripping mold, and the printing factory only needs to form the bottom module.
Making stripping bottom molds is cost-effective and time-saving. Save a significant amount of money for the printing factory.
2. Short debugging time, Easy to operate
It only takes 10 to 15 minutes to set up an offline stripping machine for a new product. Workers with no prior experience can learn to operate proficiently in one day. The entire machine can be operated by one person.
The PLC system has 300 sets of production memory at the same time, and for the same box type, the data can be recalled with one key without debugging.
3. Strong adaptability, suitable for a wide range of products
Because the commissioning time is short and there is no need to change the board, the printing factory can also handle smaller orders or different box-type products efficiently. It is also suitable for some products, such as low-toughness paper and soft paper. It is adaptable to different printing products and is better suited for factories with various orders.
4. Cost-effective
The most advanced fully automatic waste stripping machine can perform automatic palletizing and waste stripping at the same time with high efficiency. It takes only 1 minute to finish stripping one pile of sheets, and the overall cost performance is superior to the die-cutting machine with stripping section.
