1. Servo drive with invention patent has the following obvious advantages over hydraulic drive (patent type: invention patent; Name of invention: a vertical parting molding machine; Patent number: ZL 2020 1 0320484.2) Pure electric molding machine has the advantages of hydraulic molding machine, so that the end user can reduce consumption and energy saving in each mold, and virtually reduce the start-up cost. To enable users to improve the boot time, reduce maintenance costs, reduce spare parts consumption, reduce environmental pollution, improve the working environment. 2. The guide rod, wear-resistant base plate and other wear-resistant parts are made of high hardness tungsten carbide surface treatment than the traditional chromium plating life increased by more than 10 times
