Detailed introduction

Pp pencil case pencil-box ultrasonic plastic welding machine is the use of ultrasonic technology for welding, general stationery products with ultrasonic technique is more, effect of ultrasonic welding stability.Pp polypropylene has many excellent features: 1, the relative density is small, only 0.89-0.91, is one of the lightest varieties of plastics.2, good mechanics performance, in addition to the resistance to impact and other mechanical properties are better than polyethylene, processing performance is good.3, has higher heat resistance, continuous use temperature can reach 110-110 ℃.4, chemical performance is good, almost no water absorption, and does not react with most chemicals.5, texture, pure, non-toxic.6, good electrical insulation.7, the transparence of polypropylene products better than transparency of high density polyethylene products.Pp it has many advantages but also disadvantages: 1, the product cold resistance is poor, low temperature impact strength is low.2, products in the use of easy by light, heat and oxygen and the effect of aging.3, color is not good.4, easy to burn.5, toughness is bad, electrostatic degree is high, dyeing, printing and binding. 

Pp pencil case pencil-box ultrasonic plastic welding machine advantages: 1, welding speed, welding of high strength, good sealing,2, to replace the traditional welding/bonding process, low cost, clean pollution-free and does not damage the workpiece;3, stable welding process, welding parameters are all can through the software system for tracking monitoring, once found it easy to fault and maintenance.

Pp pencil case pencil-box ultrasonic plastic welding machine machine warranty for a year, ultrasonic mould warranty for three months.
