Injection molding is utilized for comparatively tiny complex pieces and big production processes, whilst thermoforming is used for massive patterns and small-scale manufacturing runs. Here are some quick comparisons of the two methods.
The servo motor injection molding machine must achieve to target to attain precision which is the pressure control accuracy and system accuracy. The pressure control accuracy is a reliable and advanced PID algorithm that ensures the fluctuations range of the system is less than - or + 0.5 bar so that high-quality products are achieved.
Perhaps the most noticeable difference between parts made by injection molding and parts made by blow molding is that injection molding creates solid parts, while blow molding creates hollow parts. If you’re producing something that needs one rigid wall, injection molding may be what you’re looking for. Some common examples of parts created with injection molding are bottle caps, hair combs, and housings for computers and televisions.
Generally speaking, high-speed injection molding machines are all electric motors, while ordinary injection molding machines are hydraulic injection molding machines, and hydraulic injection molding machines operate relatively slowly.
The main working principle of plastic molding machine is to use the plastic thermal physical properties. First, we auto loader the plastic material into the barrel, which is surround by heating elements melting the plastic. In the barrel which is assembled with servo motor screw.
The demands for personal protective equipment and healthcare implants, on the other hand, has fueled an increase in injection molding machines, which has increased its use of mechanization with an emphasis on reducing manufacturing cycle time and improving production capacity.
UPVC has high melt viscosity and poor fluidity. Even if the injection pressure and melt temperature are increased, the fluidity does not change much. In addition, the molding temperature of the resin is very close to the thermal decomposition temperature, and the temperature range that can be molded is very narrow, making it a difficult material to mold.
