3.The fabrication

Our plastic injection machines could do the mold injection parts and the assembles from 0.005kgs to 1.5kgs,

we are also experienced in the stamping,the bending,and the welding,our equipments are advanced in these fields,

so we are always doing the exellent fabrication job.In the fabrication,we often use the melting welding,

the pressure welidng,and the laser welding,the welding robot could do the welding fabrication effeciently and economically,

meanwhile the experienced technicians do the melting welding perfectly,the welding seam is straight,

there are no gaps,no holes,no welding slags.All of our welding workpiece could pass the air-tight test successfully,

our technicians also do well in the pressure welding and the laser welding,the workpiece is strong and beautiful.
