1. Oscillation frequency adoption in international industry frequency wave band 27.12+0.6 or-0.6. and establishes frequency stabilization circuit. So this machine output wave form is good. excursion is small .frequency stability. 2. CHD-4Yfeet trample high frequency plastic welding equipment initiates the high frequency oscillator with hot join frame integration the design. shortening the high frequency electric currents feed loop and decrease loss. so this machine not only electric-hot efficiency is high but also using ground area is small. 3.CHD-4Y feet trample high frequency plastic welding equipment operate system matches the person and the machine engineering request is simple .aim at the different request .our company contains various operations method to provide the customer with the Choice . 4.CHD-4Y feet trample high frequency plastic welding equipment exportation power adoption modulator regulates .according to length or short of the product sealing material and thick or thin to set up oscillating electric current to satisfaction the welding request. Guarantee the uniform of the product . 5. CHD-4Y feet trample high frequency plastic welding equipment establishes the high sensitivity of spark protection circuit .can accurately testing to find out does not equilibrium electric current by the spark producing .the moment that produce in the spark cuts off to oscillating circuit. Repressing the spark. Protecting mould. 6. CHD-4Y feet trample high frequency plastic welding equipment establishes perfectly the protection equips. at lose to press lack photo over circuit over catty the excrescent circumstance in etc. all can cut off to oscillating circuit. 7. A unique product structure :gap of nose regulate the scope big within the limites permitted . the pressure of air cylinder can tiny to adjust .upside electrode prepare the hot temperature even and regulate the convenience .timing unit establish welding time .counter statistics the product quality .
