z******f

Gisen type d amplifier is developed containing special Electro-Magnetic Interference Suppression Components. These components help reduce or eliminate noise caused by electromagnetism. It is multi-functional, which supports three kinds of working modes: forming, cutting, and stacking

f******t

To prevent electric leakage and other current issues, Gisen top 10 power amplifiers is exclusively designed with a protection system, including using quality insulation materials. The heater in the product is equipped with an intellectual temperature control system

d******e

In order to ensure users' safety, Gisen top 10 power amplifiers is strictly tested and has been certified under many international standards including FCC, CCC, CE, and RoHS. The movement guide column of the product ensures the items are stacked neatly

k******q

During the production of Gisen top 10 power amplifiers, pollution or waste components generated from the production process is carefully and professionally treated. For example, the failed capacitor will be collected and disposed to a certain place. It can automatically trim the edge of the processed item

t******c

Gisen type d amplifier is made of materials which are carefully selected and sourced. The raw materials used do not contain any toxic or harmful substances such as mercury, lead, polybrominated biphenyl, and polybrominated diphenyl ethers. With a full servo drive, it has a reduced clamping force, ensuring the fast and precise clamping work

h******e

The defective products are eliminated through strict quality inspections. Auto roll sheet loading and quick mold change system can help save labor while improving work efficiency
