Today, Yankang will share the crusher operation specifications with you. Before the crusher operation, the crushing staff must carefully read this «crusher operation specification », master the working principle, structure, and performance of the machine, maintain and maintain the crusher according to the standard, and work on the job after qualified training. When working, operators shall wear working clothes and masks, and shall not wear slippers and vests. Before starting the equipment, check whether the bolts are loose, and check and…

The cooling of blow molding machine is generally divided into extruder system cooling, hydraulic system cooling, and product cooling. Cooling of  blow molding machine — cooling of the extruder system The function of screw cooling divided into Water cooling and Fan cooling .in order to eliminate friction overheating, stabilize the extrusion pressure of plastics, promote the uniform mixing of plastics, and improve the plasticizing quality. But its use must be appropriate, especially not too much, otherwise, the barrel of plastic…

The maintenance of the hydraulic device is the hydraulic system overhaul, the hydraulic components as a basic component of blow molding machine. The hydraulic system is mainly composed of: power components, executive components, control and adjustment components, auxiliary components, and working medium five parts. The main points of maintenance and repair of hydraulic components are summarized as follows. 1.Hydraulic Components-Hydraulic pump maintenance points (1) After the hydraulic pump is disassembled, check the wear of the internal friction pair of the…

We often can discover, plastic productions more or less can appear after long-term deposit fade conditions. So why do plastic productions fade? Today, YanKang will show you the fading reason for plastic productions scientifically. Let’s get to know! Sunshine resistance The light resistance of colorants directly affects the fading of products. For outdoor products exposed to strong light, the light resistance (sun resistance) grade requirement of colorants used is an important index. Poor light resistance, products will quickly fade in…

Today, Yankang shares with you about blow molding machine in winter about anti-freeze and maintenance measures. At the beginning of the New Year, rain and snow hit, and the temperature dropped to below zero. After the shutdown of the plastic blow molding machine, attention should be paid to anti-freeze, so as to prevent the components from being damaged due to icing. Winter Anti–freeze And Maintenance Measures 1. After shutdown, the residual circulating water in the cooling system must be cleaned to avoid freezing…

Glass fiber reinforcement is based on the original pure plastic, adding glass fiber and other additives, so as to improve the scope of use of materials. Generally speaking, most of the glass fiber reinforced materials are mainly used in the structural parts of products, which are structural engineering materials, such as PP ABS PA66 PA6 PC POM PPO PET PBT PPS. What decisive role can fiberglass enhancement play in blow molding? Firstly, it has the following advantages: After glass fiber…

In the production process of blow molding barrels, color difference may occur. Today, Yankang will share with you the solution of color difference in the production process of blow molding barrels. Problems with blow molding machine parts The blown screw of the blow molding machine has a damage gap for a long time, and there is a material dead angle at the notch. During the production process, the previous batch of different color raw materials slips, resulting in an uninterrupted…

Today, Yankang will share with you the debugging and maintenance of the plasticizing system of the blow molding machine. Debugging of plasticizing system 1) the heater of the plasticizing system must be tightened uniformly. The heater should closely and evenly adhere to the heating surface. Aiming at the mica heater, the rubber hammer should be used to gently beat the mica heater while fastening to ensure close fitting, which is conducive to uniform heating and prolong the service life of the…

Today, Yankang shared with you the operation and maintenance of blow molding machine. The operator must be familiar with the blow molding machine that he is operating. It is necessary to correctly grasp the characteristics of the screw, the control of heating and cooling, the characteristics of the instrument, the structure and assembly of the control mold of the tractor. In order to correctly grasp the extrusion process conditions and operate the machine correctly. The first step is the first…

Today, Yankang shared with you the information about blow mold polishing. There are two main purposes for polishing the mold: one is to increase the brightness of the plastic mold and the appearance. The second is to make the mold easy to demould. In the polishing process, the surface of the machined mold cavity is generally coarsely ground using coarse oil stone, and the tool mark of the machine plus the tool is polished. Then use fine oil stone to…
