PCTG plastic ultrasonic welding

1. PCTG, clear and transparent, excellent impact resistance, high chemical resistance, excellent injection molding properties, high temperature resistance, good secondary processing properties such as ultrasonic welding, strong scratch resistance is used for baby bottles, space cups , The best plastic for soymilk and juicer.

Due to people’s pursuit of quality of life and health, the market’s environmental protection requirements for plastic raw materials are also increasing. For example, BPA will be produced after the hydrolysis of PC. Recent studies have shown that humans (including animals) have long-term intake of trace amounts BPA is very likely to have an adverse effect on the reproductive system and destroy the balance of sex ratio. Therefore, some countries and regions have restricted or banned PC. PCTG is a new type of environmentally friendly material that overcomes this defect. It also has good ultrasonic welding. Performance, according to the product size, it is recommended to use 20khz high-power ultrasonic welding for welding.

2. The traditional outdoor sports bottle generally adopts PC injection stretch blow production bottle body, double-layer nested structure, hollow inside, ultrasonic welding, no water leakage, hot water inner layer does not produce steam, but because PC has the problem of BPA, PCTG is used instead of PC to produce the bottle body, and the strength and transparency of the bottle can still maintain the level of the PC bottle.

The body of the PCTG sports water bottle adopts a two-layer plastic hollow structure, and the welding surface adopts a convex-groove structure. The welding surface is welded by an ultrasonic welding machine. The welding surface is clean and beautiful.

The welded PCTG sports water cup needs to be steamed for a long time at a high temperature of 100 degrees, and can withstand repeated cleaning for several hours in a dishwasher with high-pressure spray and high-temperature steam. The hollow structure does not leak water or steam; impact resistance, no cracks, and long time It will not change color when used. After violently smashing it with a hammer, observe that the welding surface is completely welded.
