TUM - Industrial Vertical & Horizontal Plastic Injection Molding Machines Manufacturer From Taiwan

Located in Taiwan since 1993, TOP UNITE MACHINERY CO., LTD. is an industrial plastic injection molding machine supplier that provides types of plastic injection molding machines, including horizontal injection machine, dual color servo energy-saving injection machine, vertical servo energy-saving toggle injection machine and auxiliary equipment (dehumidifying dryer).

Top Unite machinery provides high-quality plastic injection molding machine, including horizontal (clamping force 50 ~ 550ton), vertical (clamping force 60 ~ 150ton) and dual color (clamping force 260 ~ 660ton). We insist on using Bosch Rexroth hydraulic components in the injection unit, overall, the excellent and stable performance that can apply to plastic parts in variety industries.

TUM delivers plastic injection molding machine and develops multiple models to assist in plant optimization, both with advanced technology and 42 years of experience, TUM ensures each customer's demands are met.

What is the difference between an energy-saving injection machine and a traditional injection machine?

Comparing with energy-saving injection machines and traditional machines is a different type of power source, one is a servo motor the other is an induction motor. The biggest difference between the induction motor and servo motor is the way to building pressure.

The servo motor can change the rotating speed depends on the user's setting. Through the feedback of the pressure transducer to change rotating speed to correct pressure and flow output.

To the induction motor, the rotating speed is unchangeable it always stays in a maximum rotating condition since it operating. No matter how much pressure or flow you've set up, the power consumption will keep at a high condition.

If you have plans to purchase injection molding machines, Top Unite provides you with the following options.

    TUM launches medium and large-size Hydraulic Injection Molding Machines ranging from 180ton to 750ton. It comes with a high-performance electro-hydraulic control system, by the German Bosh Rexroth solenoid, and a proportional pressure relief valve (both with Lvdt). We use a double fixed displacement vane pump to provide hydraulic pressure and flow source make these two pumps confluent, which gives an advantage to boots up the speed of the machine to raise the production output.
