Extrusion System

The 5L stretch blow molding machine adopts a world-renowned brand automatic temperature control device. An electromagnetic motor reducer is used to drive the screw to achieve stepless adjustment. The screw material is 38Cr, and the screw edge is spray-welded with nickel-based + 10% carbon composite alloy; adjusted to qualitative, alloy, and nitriding.

Clamping Device

The design and performance of the mold clamping device have an important impact on the stability of the blow molding process and product quality. It needs to be able to provide sufficient clamping force to ensure that the mold does not move during the blow molding process, and it also needs to have a certain degree of flexibility to adapt to different production requirements. Operators often need to adjust the parameters of the clamping device according to specific production conditions. Maiwei stretch blow molding machine adopts a double-axis single-cylinder two-way synchronous mold locking device to ensure good stability of the equipment.

Air Blowing Device

The blowing device of the stretch blow molding machine is used to extrude the preheated plastic through the extrusion head and inflate it in the mold to form the desired product shape. The stretch blow molding machine is top blow type. Throughout the blow molding process, air blowing devices need to work together to ensure that the molten plastic forms a consistent, stable product within the mold. Adjusting the parameters of the blow molding unit can affect the thickness, shape and quality of the product.

Hydraulic System

The hydraulic control system includes controllers, sensors and actuators, which are used to monitor and adjust various parameters of the hydraulic system to ensure the normal operation of the entire blow molding machine and produce high-quality plastic products. The entire hydraulic system of the Maiwei stretch blow molding machine adopts world-renowned brand control components and proportional control circuits, with fast response, low energy consumption and low calorific value.

Application of 5 Liter Stretch Blow Molding Machine

A stretch blow molding machine is a device used to make plastic products by heating and injecting plastic pellets into a mold, and then using airflow to blow the plastic into the desired shape. A 5-liter stretch blow molding machine usually refers to plastic products with a capacity of 5 liters. It has a wide range of applications, covering product manufacturing in many daily life and industrial fields. Here are some application areas for 5 literstretch blow molding machines:
