In fact, its bad is caused by various reasons, and these reasons are not only one, but also caused by many aspects. The same is true of Aluminum Composite Panel https://www.alubang.net/ , so what factors are related to the quality of aluminum composite panel ?
1. Environment
It is required that the interior of the painting room should be clean, with dust-proof, insect-proof and certain ventilation functions, so as to ensure that the surface quality of the aluminum composite panel is not polluted. Meanwhile, the process conditions should be changed in time due to the change of air temperature.
2. Raw materials
The coating of aluminum composite panel is the most important factor that can affect the coating quality in the coating process. Because of the difference between the batches of coatings, the unevenness of aluminum composite panel , uneven film thickness, and poor flexibility of edge also directly affect the... less

Apart from the hard factors such as plastic raw materials, colorants and the smoothness of the mold surface, what other reasons will cause this situation?
(1) poor mold finish, rust on the cavity surface, and poor mold exhaust.
(2) The gating system of the mold is defective, so the cold well, runner, polishing runner, shunt and gate should be enlarged.
(3) The material temperature and mold temperature are low, so local heating method of gate can be used when necessary.
(4) The processing pressure is too low, the speed is too slow, the injection time is insufficient, and the back pressure is insufficient, resulting in poor compactness and dark surface.
(5) Plastics should be fully plasticized, but the... less

2. For cylindrical bottles, especially those less than 30mm in diameter, BOPP labels materials should be carefully selected.
3. If the object to be pasted is an irregular surface or a spherical surface, the material type, thickness and adhesive of BOPP labels should be specially considered.
4. Label with automatic labeling machine, and conduct labeling experiment when necessary.
5. Even if the 5.BOPP labels is labeled at normal temperature, attention should be paid to whether it experiences high temperature during transportation and use.
6. More water or oil will affect the properties of adhesive, so attention should be paid to the environment and temperature of BOPP labels.
After explaining the requirements of BOPP labels in detail, such as the surface to be pasted, labeling... less

2. Hygroscopicity is a good variety of synthetic fibers, so garments made of nylon are more comfortable than polyester garments.
3. It is a light weight fabric, only listed in polypropylene fiber and acrylic fiber fabrics of synthetic fiber fabrics. Therefore, it is suitable for mountaineering clothing and winter clothing.
4. The elasticity and elastic recovery are excellent, but it is easy to deform under the action of small external force, so the fabric is easy to wrinkle during wearing.
5. Both heat resistance and light resistance are poor. Care should be taken to wash and maintain the fabric during wearing so as not to damage the fabric.
6. Nylon fiber is made by hand and is stronger than natural cotton fiber, while nylon fiber is much longer than cotton fiber.

1. Prepare plastic materials. The brand-new plastic raw materials purchased from outside and the recycled secondary materials are fully mixed by a mixer according to a proper proportion to prepare plastic raw materials for production.
2. Coloring the ingredients. If the household product mould needs to be colored as a whole according to the design requirements of plastic products, the colored injection-moulded parts can be obtained by adding corresponding colorants into the plastic raw materials before injection moulding and mixing them evenly and fully.
3. Drying the baking material. According to the requirements of injection moulding process, plastic raw materials should be fully dried and free of moisture, so the raw materials should be dried by a dryer before injection moulding.
When printing BOPP labels, we should clearly understand the customer's requirements for the length of label use. We should know that the quality of labels printed by different materials is quite different.
2. Environment.
The difference between BOPP label printing and environment can be said to be closely related. Generally, attention should be paid to factors such as sunlight exposure and cleanliness.
3. Roughness.
In this respect, the smoother the printed label surface, the greater the corresponding use.
