<p>Classification of injection molding machine</p><p><br></p><p>What types of<a href="https://www.hisson.com/product" rel="noopener noreferrer" target="_blank"><strong> injection molding machines</strong></a> can be divided? The following is a brief introduction to the classification of injection molding machines according to plasticization and mold clamping methods</p><p><br></p><p>HXM 298-HXM servo injection molding machine</p><p>(1) Classification by plasticizing method</p><p>1. Plunger type plastic injection molding machine</p><p>Its mixing property is very poor, and its plasticity is not good, so it is necessary to install a diverter shuttle device.

Screw-plunger type <a href="https://www.hisson.com/pet-preform-injection-moulding-machine" rel="noopener noreferrer" target="_blank"><strong>plastic injection molding machine</strong></a> depends on the screw for plasticization and the plunger for injection, the two processes are separated.</p><p><br></p><p>(2) Classification by mold clamping method</p><p>1. Mechanical</p><p>2. Hydraulic type</p><p>3. Hydraulic-mechanical</p><p><br></p><p>Function of injection system of injection molding machine: The injection system is one of the most important components of the injection molding machine. There are generally three main types of plunger, screw and screw pre-plastic plunger injection. The most widely used is the screw type. Its function is that in a cycle of the plastic injection machine, after a certain amount of plastic is heated and plasticized within a specified time, under a certain pressure and speed, the molten plastic is injected into the mold cavity through the screw. After the injection is completed, the molten material injected into the mold cavity is kept shaped.</p><p><br></p><p>The composition of the injection system: The injection system consists of a plasticizing device and a power transmission device.</p><p>The plasticizing device of the <strong>screw injection molding machine</strong> is mainly composed of a feeding device, a barrel, a screw, a glue passing component and a nozzle part. The power transmission device includes an injection oil cylinder, an injection seat moving oil cylinder, and a screw drive device (melt glue motor)</p><p><br></p>
