According to clients' requirement.
Check wire connector. Joint fastening wire will make joint position heat or sparks and damage, joint adverse will affect the signal transmission; joint contactor will by electromagnetic action of shock and is easy to loosen, therefore need to regularly check the line joint position and tighten. The 2 Motor General Motors are air cooling, dust accumulation will cause difficult heat dissipation, so every year for regular cleaning, usually in the circuit is provided with an overload protection device of cutter, the limited current is adjustable, shall be properly selected according to the motor power, at the same time, once the overload protection device to start, should determine the inspection whether the lack phase, contact undesirable or high temperature after the press back reset switch. 3 heating tube and thermoelectric heat tube should be incidental period check whether fastened so that can effectively heat transfer in burned, normal production of heating tube is not easy to be detected, so pay attention to the temperature controller works, from which to judge whether the normal heating tube. In addition the heating tube damage is common connection wires, as the joint of side, the increase of contact resistance, so that the connection of local overheating caused interface oxidation damage. 4 electromagnetic contactor contactor for electrothermal part because action intersection number is more frequent, the loss rate is also faster, if the main contact overheating melt adhesive may cause heating temperature control, so if found that exposure to overheat, sound or breaking when the fire is big, the table will damage, should be replaced.
Injection molding machine, injection molding machine or injection machine. It is the main forming equipment plastic products, thermoplastic or thermosetting plastics using plastic molding into various shapes. Divided into vertical, horizontal, all electric. The function of heating plastic injection, high voltage is applied to the molten plastic, so that the injection and full of mold cavity
