Today Yankang will show you the inverter maintenance of blow molding machine. And it turns out that this method is very effective. 1.Environmental Conditions 1)Temperature. Permissible ambient temperature is -10-40. Attention: the lifetime of the inverter will be lengthened in lower environmental temperatures (ideal temperature is 20-30). 2)Humidity. Permissible ambient humidity should below 90%(No water condensation phenomenon). Attention: if the ambient temperature drops suddenly will appear water condensation phenomenon easily. At the moment if only carries on drying for parts…

The main influencing factors and control methods in the blow molding process are the focus of this article. In the blow molding process of the parison, the factors that affect the molding process of the parison mainly include the temperature of the parison, the inflation pressure, the blowing speed, the inflation ratio, and the temperature of the blow mold. (1) Parison temperature The temperature of the parison directly affects the stability of the shape of the parison, the surface finish…

This article will focus on the 5 factors affecting the quality of the extrusion blow molding parison. The parison is a semi-finished tangible plastic body used in blow molding or other processing processes, generally in a tubular form. Extrusion blow molding is first to manufacture parisons, whose quality has a great influence on the performance and appearance of products. This article will focus on the factors affecting the quality of the extrusion blow molding parison. In general, the main factors…

The heating system of the accumulator dies head is divided into three parts. The first part is the temperature controller. The second part is the contactor and the third part is the heater. Today, Yankang Plastic Machinery first shares with you about the temperature controller maintenance. In recent years, the heating system of super size blow molding machine has some changes by adopting a PLC temperature module instead of the temperature controller and adopting solid state relay instead of the…

Ongoing maintenance is essential to improving operation efficiency, output, and quality of the product. In addition, it will prolong the time intervals of machine overhaul and reduce the overall operating cost of the blow molding machine. Maintenance has been ongoing from manufacture through installation and testing. Today, Yankang Plastic Machinery will share with you how to maintain the extruder of the blow molding machine. 1) Daily maintenance Daily maintenance usually completed in the starting period. do not take the running work…

The regular maintenance of the extrusion blow molding machine is to better exert the performance of the blow molding machine and produce better plastic blow molding products. Today, the editor of Yankang wants to share with you what are the regular maintenance items for plastic blow molding machines. The maintenance of the plastic blow molding machine is divided into regular maintenance and daily maintenance. Regular maintenance is the maintenance work for the entire plastic extrusion blow molding machine equipment after…

Parting surface of the blow mold is our topic today. Generally speaking, molds are composed of two parts: movable mold and fixed mold (or male mold and female mold). (More information: design requirements of extrusion blow mold) The parting surface of the blow mold refers to the part that the two can contact when they are closed. It is also the dividing surface that divides the workpiece or mold part into mold volume blocks. The design of the parting surface…

Screw of large plastic blow molding machine is an important part of the production process. When the blow molding machine is working, the screw can uniformly plasticize the raw materials into a molten state during the rotation. Extrude to the die to form the required blanks for mold forming. Simply put, the main function of the blow molding machine screw is to plasticize, melt, and convey the raw materials for blow molding. What Yankang wants to popularize with everyone today…

This post introduces the mechanism and characteristics of die head of storage cylinder blow molding machine. Blow molding machine die head, also called the head. The die head includes a perforated plate, a strainer connection tube, and a core assembly. The die heads commonly used in blow molding machines are straight-through die head, corner die head, and die head with storage cylinders. Among them, the straight-through die head direction is consistent with the axial direction of the screw. When the…
