1）The hot plate plastic welding machine is specially designed for welding thermo plastic parts.
2）During hot plate welding process, rising and downward of the fixture is executed by pneumatic system (cylinder); the fixture clamping is executed by pneumatic system (cylinder) and vacuum device(sucker).
3）The hot plate plastic machine finished welding fully automatically and with good work efficiency except load and upload the welding parts.
4）Welding movement is limited by some adjustable screws on fixture and upper and lower mould. It’s convenient to set final welding area and distance more precisely after welding
- All moving parts adopt imported linear guide rail, slider, make it move stably and more precise positioning.
- No pollution and no waste, more environmental working.
- Related parameters:
Hot plate temperature
Welding time
Welding pressure
Control unit can monitor all above parameters.
As control unit can monitor all parameters, welding distance can be adjusted also. By repeated tests, it can finally reach welding purpose.

Hot plate plastic welding machine Working principle and operation procedure
Operation procedure of hot plate welder
1 Connect 3-phase 5-wire/380V power
2 Turn power switch to start position, after 30 seconds, all systems are in running status
3 When all systems ready, loosen emergency button, close all side doors, then open ”power switch” ,touch panel start, press manual mode (refer below operation panel instruction to see specific operation), move upper mould to see if upper mould match lower mould, by adjusting adjustable fine tuning block(generally it’s well adjusted before delivery ).Then reset the upper mould;
4. Turn to automatic mode;
5 Set parameters (upper mould heating time, lower mould heating time, curing time) wait until the temperature reach setting temperature;
Operators put the welding parts in the machine.
6 Operators put on the welding parts, then press upper and lower fixture button, to clamp the welding parts. After checking, press the two green start button together, then the machine will start automatically.
7 Upper and lower cylinder will drive upper and lower mould move to heating position
8 When the upper and lower parts touch the hot plate, the plastic parts begin to melt. After heating time, the surface of the parts melt, the hot plate remove rapidly and the two parts combined together.
9 when reach setting welding time and welding depth, upper and lower fixture separated, welding finished
Operators take out the product
Attention: the switch can be effective when it’s on manual status
Upper fixture up：upper mould rising when press, stop moving when let go;
Upper fixture down：upper mould falling when press, stop moving when let go;
Slide plate forward：slide plate forward when press, stop moving when let go;
Slide plate backward：slide plate backward when press, stop moving when let go;
Lower fixture up：lower mould rising when press, stop moving when let go；
Lower fixture down：lower mould falling when press, stop moving when let go；
Upper sucker：shift switch, upper fixture clamp when turn red, fixture loosen when turn blue
Lower sucker：shift switch, lower fixture clamp when turn red, fixture loosen when turn blue
Heat off：shift switch, heating when the button turn red, stop heating when turn blue;
Fan off：shift switch,, fan work when turn red, fan stop when turn blue;
Automatic menu instruction:
Make sure the automatic button is in automatic position, time setting include upper hot plate melt time and lower plate melt time, curing time. And there is time display when running.
Delay set: slide plate(hot mould) move to working position, set different delay time of upper and lower fixture(because the position is different), to guarantee it can return after welding, time set during 0~9.99 seconds
Welding time set:the time between the part touch and left the hot plate, also called melt time, time set during 0~9.99seconds
Curing time set:stay time when the two plastic parts combined, time set during 0~9.99seconds
Clamping time:Clamps response time, time set is 0 to 99.9 seconds;
Production counter:count total production
Clear:count clear, to count daily production or shift production
Hot Plate Plastic Welding Machine Fixture
Position and horizontal is adjusted OK before shipment, so the step of fixture installation is ignored!
adjusted and fixed.
When confirmed, do welding test, adjust the fixture position according to the welding result, front and back, left and right position adjusting block could adjust fixture in horizontal direction, horizontal screws and limit pillar can adjust uneven welding or unevenness welding surface .
Tooling disassembly and change
*clean working area of machine
*check current temperature of fixture;(if upper and lower fixture is in high temperature, please wait them cool, suggest change when the fixture temperature ≦60℃);
*Remove heating tube and thermocouple connecting wires
*Keep the machine in manual mode
*You can take off lower cold mould first, hot mould and upper cold mould return to origin, rise the lower cold mould to a position that easy to take off, loosen fixing screws, then using forklift to take out the mould, you’d better pad a piece of paper board or flannel to prevent slip and scratch
*Next take off hot mould, take slide plate to working position, use forklift to take out, pad thick flannel or paper board on forks and the gap between forks and fixture ,
*Disassembly method of upper hot mould is the same as lower cold mould.
*Disassembly of upper cold mould: Make lower mould and hot mould to origin first, then insert forks, make upper mould fall, other is same as hot mould;
Attention: Please use assistant tools correctly and don’t move or upload alone, suggest use lifting forklift
Pay attention to cooperation and prompt each other
Maintenance of fixture
*Protection: Protect from dust, rust, water, fall, press;
*Other: Continuous protection of hot mould and heating tube (thermocouple).
Attention: Fixture position is adjusted well before delivery, please don’t adjust screw and nut at will.
