Liu Li gives people a feeling of luxury and is also very suitable for gift giving. The production process of colored glass is meticulous and requires the skill of the master.
At present, the production process of traditional glazed firing is divided into five steps:
The first step is to make the material. All the pigments need to be melted in the furnace to help soften the glass and rotate on the iron rod. Then, take it out from the furnace with more than 1400 degrees of high temperature and use a 1-meter long blower. The inside of the glass body, so that it is taken out in the furnace and then rotated to sculpt, the temperature of the glass taken out in the furnace is very high, and it is necessary to master the melting degree of the glass in a few seconds. This step is quite a test of the master’s technique. Because in the process of styling, the master needs to blow the blower in his hand to ensure the shape of the glass. Since the scale is very difficult to grasp, the yield is extremely low, and the time required for production is relatively long. After the glass is formed, in the final step, the master needs to put the fired glass into the insulation, about 500 degrees, and keep it for 4 days. After that, the glass will be inspected for cracking. The finished product has been rewarmed.
Among the stainless-steel gifts, the most common is 304 stainless steel, the high-temperature resistance is 800 degrees, not only good processing performance but also high toughness. Therefore, this material is widely used in household goods and food and beverage, and 304 stainless steel is also regarded as a nationally recognized food grade stainless steel.
Stainless steel processing methods are divided into two types, etching method and spray color method.
The etching process is to screen the acid-resistant protective film on the surface of the stainless steel, and then etch it with a ferrous chloride solution to form a pattern.
The other is the spray color method in which the toner particles are sprayed after screen printing to form a pattern.
The chemical coloring method of stainless steel does not require the use of pigments and dyes, but the stainless steel is immersed in a heated concentrated chromium sulfate solution for chemical coloration, which is characterized by good food resistance. The ink used in this processing method needs to have very strong acid resistance. Generally, it is necessary to use and process this process, and it is necessary to have a UV curable ink which is relatively suitable and has special properties.
Thermos MUG are corporate gifts that companies love very much. Many companies not only print their own company’s LOGO, but also use their own designs to produce their “exclusive” styles to attract corporate customers and improve their image and positioning.
Generally, the commonly used printing methods for vacuum flasks are divided into three types: thermal transfer silk screen printing and laser engraving.
Thermal transfer printing is divided into two parts: transfer film printing and transfer processing. The transfer film printing is used for dot printing. The pattern is pre-printed on the surface of the film. The effect of the printing pattern is rich regardless of the color or the slaughter. The color difference is small and the pattern is more realistic, so it can reach the designer’s original. Some requirements and effects. The only drawback is that because of the high cost of plate making, it is more suitable for customers with higher orders.
The other is screen printing, referred to as silk screen printing. The silk fabric, the synthetic fiber or the wire mesh is stretched on the frame, and the screen printing plate is still produced by hand-painting or photochemical plate making. In the process of printing the squeegee through the squeegee, the ink is transferred to the product through the graphic part. This method can print LOGO with 2-3 colors. This printing method is simple, but in use. It is easier to fade.
The last is laser engraving, which leaves a permanent mark on the product.
Laser engraving scribes’ traces of the chemical changes in the surface material caused by light energy to reveal the desired pattern or text. This method does not require making a film, it only needs to output the original file, and there is no limit. But the only fly in the ointment is that this method can only achieve a monochrome effect.
The production of handmade boxes requires sophisticated craftsmanship, and each process needs to be carefully crafted and worked with the master’s experience.
The birth of a manual box requires the combination of multiple molds, and the arrangement of the molds is very important. The process management and control in the latter stage are very important. The latter process is a production process based on the assembly of some parts. The management process should be meticulous and rigorous, and the process design should be rational. The production line needs to be separated according to the production documents, the rationality of the whole process, the accuracy of the component specifications and the rigor of the component network. Workers in the production line must be proficient in each process. They also need to categorize accessories such as blister, sponge, EVA, hardware, magnet, etc. The size must be accurate, and it is clear that each accessory will be encountered during production. The material problem, error range.
An ordinary world cover box is divided into a top cover, a bottom box, a top sponge, and a blister to form a finished product. The assembly line is the most conventional production line, and the design features of each product are different, and the production line devices will be different.
In addition to the production line arrangement, the process control of the glue and the paste is also very important. Before the glue is applied, the concentration of the glue needs to be measured to avoid environmental pollution caused by excessive glue concentration. The most important thing in the affixing process is the skilled skills and strict integrable standards to confirm smooth production.
There are 6 steps in the subdivision process. The first step is to set the shape. The shaping needs to be leveled, the mouth is aligned, and there is no high and low angle. Sometimes the double-sided adhesive tape is used. The tape must be horizontal and not skewed. It is glued and positioned, glued to glue, different materials, different glues, and need to control the amount and ensure uniform application even without leaving glue on the surface. After the glue is applied, the package is covered, and the fit is ensured that it is not lifted, and then the edge can be rubbed and scraped. The final step is to assemble all the semi-finished products and complete the production of the box.
Folders are basically stationery items that are used in every office or home. A seemingly plain and simple folder, the production process also has a certain process.
First of all, the PP material will be placed in the Pull-tab machines to produce a certain thickness of the material. Transparent is the most common, and other colors can be produced. The thickness of the regular folder is 0.2mm. When the sheet comes out of the Pull-tab machines, the machine has been cut to the required size and then electrostatically treated. The average A4 size folder is produced with a 4K offset press, which is also what we often hear about UV printing. Finally, after the printing is dried, the die-cutting machine is used to cut the model of the product. In all the places where there is a fit, and then the high-frequency machine is used for lamination, the production of the entire folder is completed.
Due to the fact that the aging time of the PP sheet is most of the customers need to print, and the general sheet will not be stored for use. Because time is long, it can’t be printed. Even if it is printed, the effect is not as good. Therefore, each time the proofing needs to be re-made, the time is about 5-7 working days, and the proofing price is relatively expensive.
