Hi everyone. I am planning to buy injection modling machine for business. But there are a lots of product specifications to look for such as shot volume, clamping force, ejector stroke etc. and I am not familiar with them. So which specifications/parameters do I need to consider for injection molding machine. I am planning to manufacture small plastic containers using LDPE and HDPE. For the machine, my current choices are Power Jet BJ90-V6 and Yizumi UN90A5.
