The hot plate welding machine adopts a platen-type structure. It uses electrical heating to transfer heat to the melting surfaces of the upper and lower plastic heating components, causing them to melt. Then, the heating plate is removed, and the upper and lower heating components melt, solidify, and fuse together. The machine consists of three main blocks: upper platen, lower platen, and hot platen, along with the hot tool, upper and lower plastic cold tools. The machine operates using pneumatic control. Now, let’s explore the precautions for using a hot plate welding machine, as provided by Jfortune, a hot plate welding manufacturer.
Before using the hot plate welding machine, perform a brief inspection of the equipment to ensure that there are no loose parts or circuit issues. Adjust various parameters of the welding machine according to the actual conditions of the plastic parts to ensure that the welding meets the relevant requirements. Preheat the hot plate to ensure that it reaches a uniform temperature and meets the welding specifications. While waiting for preheating, perform a brief inspection of other components of the welding machine. The factory can use some unused plastic samples for initial welding to check if the temperature meets the welding specifications. During the welding process, pay attention to the temperature and pressure of the hot plate to ensure they are appropriate. If any abnormal melting of the samples is observed, promptly adjust the temperature and pressure of the hot plate welding machine.
After each day’s use of the hot plate welding machine, pay attention to cleaning the equipment. Due to the high welding temperature, there may be residual plastic on the hot plate. If not cleaned in a timely manner, it can affect the quality of the plastic parts fusion. Heat the hot plate appropriately to melt the residual plastic and clean it with suitable cleaning tools. During regular maintenance, also pay attention to cleaning various components of the hot plate welding machine, ensuring they are free from dust or other dirt to prevent welding issues.
