What material is suitable for ultrasonic welding?

The invention of ultrasonic welding machine makes the products of ultrasonic welding more and more deeply into people's daily life. When using the ultrasonic welding machine, do you know the material that the ultrasonic welding machine is suitable for welding? 

There are several kinds materials which is suitable for ultrasonic welding：

1. Acetals

抗张及耐压强度高，耐磨性佳，最具强轫及强性，常用作接练、螺丝、轴承、滚筒、厨房用具等，因磨系数低，用超声波熔接时需高振动幅度及较长的焊接时间。

Tensile and compressive strength is high, wear resistance is good, the most powerful and strong, often used for coaching, screw, bearing, roller, kitchen appliances, etc. Because of low wear coefficient, ultrasonic welding requires high vibration amplitude and longer welding time.

2. Ester acid weaving and vitamin substances

超声波焊接机超声波振动时材质易变化变色，接触面不易吸收能量，焊接较困难。

The material of ultrasonic welding machine is easy to change and discolor when it vibrates, and the contact surface is not easy to absorb energy, so it is difficult to weld.

3.聚丙烯

3. Polypropylene

比重轻，有良好绝缘性，强度高，能耐热及化学剂的侵蚀，抽丝后可制成绳纲等织品。制品有玩具、行李箱、音乐外壳、电气绝缘物、食品包装等。本材质因弹性系数低，易衰减声波振动，较难熔接。

Light weight, good insulation, high strength, heat resistance and chemical erosion, can be made into rope and other fabrics after wire drawing. Products include toys, suitcases, music shells, electrical insulators, food packaging and so on. Because of its low elastic coefficient, this material is easy to attenuate acoustic vibration and difficult to weld.

4. Propylene butadiene

苯艺烯共聚物,质轻，兼具轫性，刚性与耐化学品性，用途广泛，此材质导热性佳，特别适合超声波焊接。

Benzene copolymer, light weight, both brevity, rigidity and chemical resistance, has a wide range of applications. This material has good thermal conductivity, especially suitable for ultrasonic welding.

5.聚苯乙烯

5. Polystyrene

比重轻，对水及化学物之抗蚀性强，安定、绝缘性佳，特别适合于射出及押出成形，常用于玩具、装饰品、盂洗设备、磐子、透镜、浮动轮等的制造。由于弹强性系数高，适合超声波焊接。

Light weight, strong corrosion resistance to water and chemicals, good stability and insulation, especially suitable for injection and extrusion forming, often used in toys, decorations, peeling equipment, pans, lenses, floating wheels and other manufacturing. Because of its high elastic strength coefficient, it is suitable for ultrasonic welding.

6.压克力

6. Acrylic

硬度大、耐重击、不受酸之作用，有高度光学明晰性，著色性良好，常用于汽车尾灯、义表板、奖章、水龙头把手等。用于超声波焊接机时，须注意衰明度问题。

Hardness, strong impact resistance, no acid effect, high optical clarity, good coloring, often used in automobile taillights, signboard, medals, faucet handles, etc. When used in ultrasonic welding machine, attention should be paid to the problem of fading brightness.
