Flexographic production of playing cards

<

Playing cards are the most common cultural and entertainment products. The demand is huge. The annual demand in our country amounts to more than one billion units and there are as many as one hundred or two production companies. The main production bases are located in Zhejiang, Jiangsu, and Shanghai, and their quality levels are high or low, but there is a big gap compared with foreign products.

After many years of exploration, the production of our country's playing cards has changed from embossing to offset, from a single deck of multiple sheets of paper to a deck of cards. One piece of printed matter is double-sided into the oven for drying, calendering, die-cutting, tearing, then die-cutting, box-packing, and the whole process is impeccable, and the production efficiency is relatively high.

The paper used for playing cards, except for Zhejiang Ningbo San A Group Co., Ltd., Yangzhou Yuren Paper Co., Ltd. and Hangzhou Yuren Paper Co., Ltd., has papermaking and casting techniques. The remaining manufacturers use semi-finished paper for composite processing. In order to reduce the cost, the cast and coated paper used on the back and side has a wood pulp content of 15%-30%, a base paper of 55-60g/m2, and a cast coating material of up to 70-75g/m2, which saves both cost and surface gloss. . The middle blue core paper is 100-110g/m2, compounded with polyvinyl alcohol glue, and the offset printing substrate is prepared after drying and calendering. The quality of playing cards produced by this process is difficult to guarantee. The main disadvantages are as follows.

1. In order to print on inferior paper, the cast coating process is used to improve the surface smoothness, the product flexibility is not enough, and it is easy to break; the cast coating material and glazing material are harmful to consumers' health and cannot be like the world famous brand (Bee brand) The embossing process is performed in that way.

2, in the production process due to the use of offset printing process on the cast coating material, and then glazing urine aldehyde resin, baked flat, even worse, can be identified from the back of the brand of light.

3, after the paper offset printing glazing, baked in a free state, can not shrink evenly, so that the cutting tool size does not match the size of the card, the size is not accurate, seriously affect the quality, which is a common problem in poker brand production companies.

There must be a major breakthrough in the production process of playing cards. The single-sheet offset printing must be changed to web flexo printing, and the discontinuous process is a continuous process.

The size of the American Bee brand, J, Q, and K, is observed under a magnifying glass. It is a combination of color blocks. There are no outlets. Obviously it is not an offset printing but only a flexo printing. Flexo printing using ink printing, adhesion, vivid degree is very good. And the flexo-printed web can be finished once by the paper-storage mechanism, the paper-making mechanism, reverse glazing, positive and negative positioning, four-color glazing, embossing, vertical and horizontal cutting, and collection of torn cards. Accurate overprinting and die-cutting greatly increase production efficiency, reduce costs and ensure quality.

At present, China Zhejiang Ningbo San A Group Co., Ltd. and Hangzhou Yuren Paper Co., Ltd. and Zhejiang Sanjian Printing Co., Ltd. have begun to use flexo printing technology to produce playing cards.

However, due to the long-established industry habits and spending habits, matt-type playing cards have not yet been fully accepted. The main reason is that most of our country's poker cards are low-grade products produced with inferior paper, for only one pursuit of low cost, low The price of the market environment, companies are also difficult to survive.

Because the oil coating and glazing process of the flexo printing machine is not as large as the traditional process, the maximum wet coating weight on the surface is not more than 6 g/m2. If the production process using a flexo press is based on the ordinary process, it can only be done with one deck of cards. Dae-jung's entry into the traditional craftsmanship can also be adapted to the current Chinese market and still be an efficient printing machine.

The progress of technology is endless. At present, many domestic manufacturers have started the research of low-cost and low-coating bright and smooth coating agents. It is believed that this technology will not be used for too long. Chinese poker brand will surely go to the world

Kitchen Hardware

1.Hinges
The role of the hinge is to connect the cabinet and the door panel, in eating at the same time it is still alone to bear the weight of the door panel, keep the door arrangement with consistency. For hinges, cheap or try not to buy, it is not like a washbasin can say change, good hinges not only long life, installation is also more convenient.
2.Slide rail
If the hinge is the heart of the cabinet, slide rail is equivalent to the kidneys. Large and small drawers can be free to push and pull, depends on the slide rail. Slide rail has roller, steel ball, gear three kinds of classification.
3, damping
Damping is mainly with the slide and hinges, has two important roles, one is to prevent shock absorption, the second is to enhance the accuracy of hardware. Damping hinge is a kind of hinge, can also be called hydraulic hinge. It can close the cabinet in a certain zone by itself, even if the force to close the door, can also slow down the speed to close the cabinet.
4.Hanging code
Hanging code is a small hardware accessory that can be hung on the wall, it can realize the link between the hanging cabinet and the wall. General steel invisible hanging code is stronger, aging cycle is relatively long.
5.Pull-out basket
Pull the basket do not have to choose too much or too high-tech, generally one or two on it, all depending on their own use of happy can be.
6, faucet
Faucet is an essential hardware item in each of our homes. Faucet good or bad, there are more critical five points, material, spool, bubbler, plating, water inlet hose.
Copper is currently a better material in the manufacture of faucets, also called brass.
Spool cost in 4 ~ 20 yuan are available, the more commonly used spool cost generally between 5 ~ 15;.
Bubbler is mainly installed in the spigot's water outlet end, the device that mixes and air when the water comes out. This class increases the flushing force of the water to achieve water conservation.
electroplating can enhance the corrosion resistance and wear resistance of the faucet and improve the aesthetics.
Intake hose is mainly connected at the corner valve and faucet, belonging to the class of accessories, while the hose and not resistant to high pressure and high temperature, long-term water pressure when the hose connector will come out, all in looking at the hose, the hose pipe and joint need to pay special attention to a little.
7.Water basin
Basin material can be divided into stainless steel, artificial stone, ceramic three categories. Currently used in our kitchen, mainly stainless steel. Stainless steel material has light, environmentally friendly, durable, corrosion-resistant features, the style is also more.
8.Drawers
When choosing a drawer, the general standard size control in 30cm-100cm best, 30cm-70cm is a small drawer
