How to restore the gloss of the surface of plastic packaging barrels? First, the reason for the mold: whether the cooling system of the mold has water leakage, or whether the sealing system of the mold has been damaged due to corrosion due to long-term operation. If there is water leakage in a single direction of the mold, and the leaking water flows into the mold, causing the barrel wall to be dull, it is only necessary to replace the sealing strip to deal with the problem of water leakage in the plastic barrel. If the exhaust system of the mold is not good, which leads to excessive gas remaining in the mold during production, causing the brightness of the barrel wall to decline, then it is necessary to check the exhaust system of the repair mold. Of course, it may also be the problem of raw materials. First, understand its materials and functions, and adjust a reasonable process formula. If the sol fluidity of the material after heating is poor, the barrel wall will appear to be not bright enough. Properly add some low-pressure resins, improve the barrel temperature, and deal with other related problems.

The volume of the plastic bucket oil tank is too small, the heat dissipation area is not enough, and the cooling device has too small capacity. The high temperature of climate and operating environment causes the oil temperature to rise. The viscosity of the selected oil is not appropriate, the viscosity is large, the viscosity resistance is large, and the leakage will increase if the viscosity is too small, both of which can cause heating temperature rise. The pipeline of the plastic bucket system is too thin and too long, too much bending, and large local pressure loss and pressure loss along the way. The precision of components is not enough and the assembly quality is poor, and the mechanical friction loss between relative motions is large. The fit clearance of the mating parts is too small, or the clearance is too large after use, resulting in large internal and external leakage, resulting in large volume loss. For example, the volume efficiency of the pump is reduced, and the temperature rises quickly. The constant displacement pump oil supply system of the plastic bucket with the oil pump capacity selected according to the fast forward speed will have most of the excess flow overflowing from the overflow valve under high pressure and generate heat during operation. The unloading circuit in the system fails or the oil pump cannot unload when it stops working because no unloading circuit is set. All flow of the pump overflows under high pressure, causing overflow loss and heating, resulting in temperature rise.

The plastic bucket for holding water is made of PE raw material, and its composition is attributed to linear low-density polyethylene particles. The plastic bucket made of this raw material is very healthy and environmentally friendly, and meets the national food safety standards. It not only has rigidity and resistance, but also has advantages such as high temperature and cold resistance. Generally speaking, plastic buckets have two purposes, one is to hold water, the other is to hold some corrosive liquids, so their choice of raw materials is different. Plastic buckets used to hold water should be environmentally friendly, green and healthy; The drums for storing corrosive liquids are required to be resistant to acid and alkali and corrosion. Plastic bucket is widely used in civil, agriculture and industry, and its scale of use can be classified as follows: 1. Civil: it is used to store and supplement at night (urban water consumption is low) because of drinking water supply problems, and it is used to make up for the overall water supply system when water consumption is serious; 2. Agriculture: when the rain is scarce, it is used to make up for the water content of farmland crops and drinking water for farm animals; 3. Industry: It is used to store industrial raw materials, and has ambitions for various acidic and alkaline industrial raw materials. Plastic buckets are ubiquitous in our lives. Because of their strong adaptability to the environment and high tear resistance, plastic buckets are loved by modern people, widely used in some factories, enterprises and individual families, and have been recognized and praised all the time.

The main features of the chemical plastic bucket are as follows: the product color is bright and round: the imported food grade color masterbatch is used to make the product dyed evenly and the appearance more bright and round; 2. The wall thickness of the whole barrel is uniform and symmetrical: 360 points of wall thickness control skills make the wall thickness of each barrel very uniform; 3. The appearance of the product is clean and smooth: people rely on clothes and horses rely on saddles - each one has a specialist to recheck to ensure that there are no black spots, strains, ribbons, deformation, etc. on the surface of the barrel, so as to improve the beauty; 4. Humanized planning of the whole barrel: each barrel shape fully considers the humanization at the beginning of the planning, making the products more comfortable to carry and more convenient to pour; 5. Diversified sealing methods: aluminum foil induction seal, inner plug seal, chemical foaming seal ring seal, WAKE silicone seal, EPE seal; 6. Excellent chemical stability and anti drop test: ensure the safety of product transportation, especially the transportation of hazardous chemicals; 7. High beauty of the can body: high cost performance and strict control of concave convex deformation, which conforms to the beauty of international review; 8. The first article test of the batch includes: high temperature stacking test, hydraulic leakage test, air tightness test and drop test.

When the surface of the plastic bucket is labeled, the labeling surface should be flat. A "frame" can be designed on the surface of the plastic bottle, so that the label can be positioned accurately without movement. During blow molding, the first contact part of parison inflation always tends to be the first hardened part. Therefore, the wall thickness of this part is also larger. The edge and corner are the parts where parison inflation contacts, and the wall thickness of this part is small. Therefore, the edges and corners of plastic bottles should be designed as rounded corners. The rigidity and bending resistance of plastic bottles can be improved by changing the surface shape of the plastic bottle, such as making the middle of the plastic bottle relatively thin, and increasing the circumferential grooves or ribs on the surface of the plastic bottle. The longitudinal grooves or stiffeners can eliminate the deviation, sagging or deformation of plastic bottles under long-term load. The printing surface of the plastic bucket is where consumers focus their attention. The printing surface shall be flat and continuous; If the plastic bottle contains a handle, a groove, a reinforcing rib and other structures, attention should be paid not to inconvenience the printing operation during the design. The elliptical plastic bottle has high rigidity, but the manufacturing cost of the mold is high. Therefore, in order to ensure the rigidity of the plastic bottle, in addition to selecting materials with high rigidity, it is also necessary to enhance the rigidity and load resistance strength of the plastic bottle through the shape design of the plastic bottle.
