Anodized aluminum foil varieties, manufacturing process, batch, different performance, attention should be paid in addition to the correct selection of outside processing Processing.

A. stamping before a new process or a new model using a foil foil, should be a simple visual inspection to see whether the model is consistent with the hot material; the rewinding of anodized aluminum foil open, observe the film surface Are there blisters, scratches, wrinkles and feel is smooth, light intensity is desirable. Good quality anodized aluminum foil reflected light is strong, glistening. Such as the use of instruments to measure light reflectance should even reach 85%. Unconditional can be visually identified.

B. foil stamping foil plates generally copperplate (copper), zinc plate and copper zinc plate three. When used in copperplate as well, because copperplate heat, heat resistance, there is a suitable flexible than the other two plate stamping durable and good effect. If the stamping of small quantities of paper work or leaflets, the choice Xinban. Zincograph soft texture not too many times larger or stamping pressure, otherwise the plate variable type, poor stamping effect. Some units only zinc plate, sometimes need to change the version number of blocks, causing great waste.

Stamping plate thickness is 1.5 ~ 2.5mm. Depending on the situation to be hot material texture, thickness, etc., appropriate choice of the thickness of the plate. Stamping Stamping edition graphic appears too thin fuzzy blur phenomena, too thick wastage.

Outside the processing stamping version, use before the first check whether there are glitches forum is not smooth, irregular edges, graphics, etc. are not clear, substandard parts to corrode, and then trimming the version stamping.

C. anodized aluminum foil checked, stamping version Shang Hao, the first trial hot; and want to stamping material texture, tone or area, such as version control and pressed the temperature, time and pressure needed.

The above three points are the main part of the stamping process.

Stamping pressure book envelope, except the outer cover fabric is generally indentation depth is about 0.4mm; stamping time is generally 0.5 ~ 1S; stamping temperature is generally 110 ℃ ~ 145 ℃. According to the surface to be hot flatness, the correct selection of different types of materials, such as pressure, time and temperature, in order to ensure the quality of stamping to achieve the desired results.
