As the first step in the production of 20 liter plastic buckets, cost accounting, in order to reduce the production cost of 20 liter plastic buckets, sometimes the manufacturer will do something on the gram weight or raw materials, reduce the gram weight or increase the secondary return material. Due to the rationality of the product planning structure at the beginning, in order to seek the maximization of profit space, the manufacturer has changed its structure and principle, which must bring corresponding problems to the use of later products, such as the sealing.
The planning of mold structure and the selection of materials will have an impact on the production of later products. If the mold planning is not reasonable, it will have functional problems in the production of later products. In the later production process, the continuous operation of the mold will cause the problem of the compactness of the deformation and mold closing, which will affect the later production products.
The pressure bearing capacity of 20 litre plastic bucket is directly related to the barrel wall. When the mold is made, the planned thickness of the barrel wall is directly related to the pressure bearing capacity of later detection. The pressure bearing capacity of 20 litre plastic bucket wall is low, and the pressure bearing capacity of wall thickness is high. If the mold is formed, the vertical value of the product needs to be improved, and the wall thickness direction of the part can be appropriately thickened. For example, for a 20 liter barrel mold, if it has an upper mouth orientation, it should be properly thickened at 8 / 12 cm down and 25 / 30 cm down, and the vertical value can be properly increased by thickening some areas of the mold.
To remove the dirt on the surface of the 20 liter plastic bucket, usually wipe the dirt with a rag first, and then scrape out the new slag with a knife. If there is any oil stain, first remove the oil with hot alkali water, then wash away the alkali liquor with clean water, and then scrape off the surface with a knife. When mending the cracks, cut a piece of the same kind of plastic that is slightly longer, wider and not aged than the cracks. Do you clean the surface, glue it all in order, and then press it again with a wet cloth to make the bonding more tight.
