During the operation of the hydraulic melamine tableware molding machine, some problems will inevitably occur. The long-term downtime due to the problem may cause serious economic losses to the enterprise. For countries except China, the cost of machine maintenance will be increased a lot. In order to meet the requirements of the continuous production of enterprises, the service life of various accessories of Shunhao Factory has been rigorously tested and continuously improved for many years. After assembly, it will be continuously tested for more than 48 hours before being exported to foreign countries to reduce the downtime of tableware factories of foreign customers and reduce maintenance and repair costs. In the continuous work of hydraulic crockery molding machine, it will cause the consumption of some accessories, such as oil seals, oil pumps, or other circuit appliances. In the normal working process of the melamine hydraulic machine, there are three main reasons for the failure of the machine. 1. The Oil Seal is damaged. This situation is mainly because of the continuous running machine, which causes frequent suppression of the machine. Long-time abrasion will cause the consumption of the sealing ring. Shunhao machine uses the NOK wear-resistant oil seal from Japan which can support the machine running for a long time. 2. High pressure and low pressure are not working properly. For small mold, it is suitable for low-pressure work, so the machine pressure is appropriately adjusted less than 150 kgs, and the high-pressure pump can be free of running to protect its parts. 3. The electrical circuit system. It’s suggested to frequently check the total power supply to prevent short circuits or damage to electrical appliances caused by phase loss. All parts of SHUNHAO machines are well-known brand parts selected after years of testing.

In the normal use of melamine tableware machine, the pressure gauge value display is abnormal, for example, the normal value should be 200, but the pressure gauge shows less than 100, we called Press Drop, how to solve it? In this case, it is judged as a failure caused by insufficient pressure of the master cylinder of the machine. Exclusion steps: Check the appearance of the main cylinder of the machine for oil leakage. Check whether the vent hole on the back of the machine's main cylinder is locked properly and whether there is oil leakage. Open the oil tank and check the pressure relief valve and pressure gauge for oil leakage. If there is no oil leakage in the above accessories, you need to disassemble the pressure relief valve (shown as the icon below) to further check the built-in condition of the pressure relief valve. Under normal circumstances, there will be 2 kinds of failures: The spool O-ring in the pressure relief valve is damaged and needs to be replaced with a new O-RING The spool in the pressure relief valve is stuck by some stuff and the spool needs to be removed for cleaning. According to the above steps, you can check clearly that the melamine tableware compression machine can work normally, pressurize and release pressure.

Decal paper is used for melamine crockery decoration. Melamine paper is put with design and glazing powder to make crockery shinning, more attractive and more creative in design. Melamine decal paper can be cut into any shapes, according to the special design concept. Melamine Decal Paper plays an important role in the creation of new sales for melamine tableware. So, how to use the Melamine Decal Paper on the melamine plate, melamine bowls? • There are different thicknesses of decal paper: 40GSM /42GSM/60GSM and normally, 40GSM is the most popular thickness. If you need to put the decal paper for high classic & high-quality melamine tableware, then Taiwan paper will be a nice choice. If not such white powder, like cream powder, then Chinese paper is the hot sales, because of its accepted quality at a reasonable cost. (For the paper quality, we may discuss by another detailed article.) • After choosing the paper, then need to cut the size to match the size of your printing machine. If you do not have the printing equipment, then the paper design factory will cut the paper size accordingly for your need. • The paper will be printed with your selected flowers and then go for drying. After the ink is dry, then this Melamine Decal Paper will be packed for delivery to your factory. • When the melamine decal paper is ready, you cannot use them directly. These decal paper needs to be covered with the shinning powder on, which is called glazing powder for foil paper. This glazing powder needs to be mixed with high temperature boiled hot water; the ratio to mix the powder with water should be properly. • Then this Melamine Decal Paper with wet glazing powder should go for drying again. Some factories dry them naturally, under clean space, no dust. But it will occupy more space to hang these papers together. So, big factories would like to run the electric decal paper drying machine, which can dry the paper fast and improve its quality as well. • When the Melamine Decal Paper is dry, this paper needs to be cut again according to its flower shape. Recently there are also 2 ways to cut the paper. 1. One is by cutting by hand. Manual cutting will take more time. Only experienced workers can work fast. 2. The other way is by cutting machine. Of course, the machine could work fast, and it spends less cost. • After cutting, the Decal Melamine Paper with flowers needs to be joined together, for the bowls, or glass, which these papers are not fully circled. Nowadays, there are also 2 ways to join the paper. 1. One is joined the paper by hand, and need to use glue. 2. One is joined with the decal paper bonding machine, without glue.

It’s quite important to make sure that the motor is running normally before the production of melamine tableware molding machine. •First, check the running direction of the motor pump after feeding the hydraulic oil. •Then turn on the Control button under Manual from the panel, and start the motor switch. •During motor running, test it some rolls then ok. If the motor rotation direction opposite the direction of the arrow marked, then reverse the connection of any 2 pieces of power wires out of 3. For many more motor problems, you can follow the steps below. There are many reasons for the failure of the motor. Some of the failures are very similar, but the causes are different. It is generally called the motor syndrome. Therefore, it is necessary to understand the cause of motor failure and to find and eliminate the cause of the failure correctly and quickly. When the fault is unknown, you can check it as follows: (1) Check whether the three-phase power supply has electricity; (2) If the power supply is energized, check the fuse, switch, and starter for faults (such as whether the screws are secure and the wiring is correct, etc.) (3) If there is no problem in (1) and (2), you can run the motor without load and check whether the fault is caused by the load; (4) If the fault occurs in the motor itself, open the junction box and check the wiring for scorch marks or other faults; (5) If there is no problem in (4), check whether the bearing is faulty or damaged and whether the grease is expired or missing; (6) If there is no problem in (5), the stator winding should be checked for scorch marks, open circuit, short circuit or breakdown; (7) Check the cage rotor for broken bars. When the motor fails, there will often be slower speed,significantly increased temperature, abnormal noise, and burnt smell, smoke, increased current, three-phase current imbalance, live case, etc. These phenomena must be grasped and analyzed。
