What Raw Materials are Used for Blow-Molded Trays? How is its Performance?

blow-molded-trays

Today, I will talk to you about what raw materials are used for blow molding of hollow blow-molded trays? How is its performance? The production of hollow blow-molded trays is mainly made of high-density polyethylene HDPE as the main raw material. A certain proportion of secondary recycled materials can be added according to customer requirements, and appropriate fillers and masterbatch can be added according to the different uses of the product. Most of the HDPE used in the production of…

Plastic Road Barrier: Blow Molding Process or Rotomolding Process?

plastic-road-barrier

Whether the plastic road barrier is better for blow molding or rotomolding has always been an issue of constant debate in the plastic products industry. The plastic road barrier is also called isolation barriers. Commonly used are cement barriers, fiberglass barriers, and plastic road barrier. Isolation barriers are mainly used for transportation facilities and play a protective role. The main thing to be discussed today is plastic road barrier. The plastic road barrier of the blow molding process can make…

Causes and Solutions for the Unsmooth Surface of Blow-Molded Products

Causes-and-Solutions-for-the-Unsmooth-Surface-of-Blow-Molded-Products

Today, let’s talk about the causes and solutions for the unsmooth surface of blow-molded products. Do customers often ask why the products blown by the blow molding machine are not smooth, like sharkskin? So why does this strange shark skin phenomenon occur? The following editor will analyze the causes and solutions of this phenomenon from several aspects. To find out the reasons and solutions for the unsmooth surface of blow-molded products, we must first understand the blow molding process: hopper…

Blow Molding Chairs VS Injection Molding Chairs Which is Better?

blow-molding-chairs-vs-injection-molding-chairs

Today we will discuss the issue of blow molding chairs and injection molding chairs. The blow-molded chair uses the principle of gas pressure to inflate the hot blank tire stored in the mold into a chair-shaped product. Extrusion blow molding is to use the extrusion method to first make the plastic into a bottomed parison, and then move the parison to a blow mold to blow into a hollow product. Except for the injection machine and extruder, the blow molding…

Influence of Screw Speed on Plastic Blow Molding Machine

influence of screw speed on plastic blow molding machine

The screw speed directly affects the output of the plastic blow molding machine and the quality of the product. The value of the screw rotation speed depends on the size and shape of the screw and the extruded product, and the type of the raw material. Increasing the speed of the screw can significantly increase the output of the blow molding machine. But the power consumption is also increased accordingly. From the standpoint of increasing production, it is advantageous to use…

Process Performance of PE Hollow Molding: Detailed Description

process-performance-of-pe-hollow-molding

The process performance of PE hollow molding is the focus of this post. PE has good molding and processing properties and is a commonly used plastic material for hollow molding. Its main process performance is as follows. ① Hygroscopicity The moisture absorption of PE is extremely small, generally not exceeding 0.01%. Therefore, there is no need for drying in the molding process. ②Molecular chain PE molecular chain has good flexibility, low melt viscosity, and good fluidity. The melt viscosity of…

3 Ways to Clean the Head of the Blow Molding Machine

Clean the Head of the Blow Molding Machine

Today, Yankang Plastic Machinery will share with you 3 ways to clean the head of the blow molding machine. It turns out that the 3 ways are very effective. It is well known that regular maintenance of the blow molding machine (the blow molding machine should be cleaned regularly, especially the screw and head of the extruder) and cleaning of the machinery, raw materials, and workshop are helpful to ensure that the blow molding is carried out normally. So, how to clean…

Influence of Production Environment on Electrical System

influence of the production environment on the electrical system

Today, Yankang Plastic Machinery will share with you is the influence of the production environment on the electrical system. Although the PLC-based electrical automatic control system is not particularly strict with the environment, in many hot and humid climates, the environment of many blow molding factories may not be suitable or the electrical automation system is not suitable for the working environment. The temperature at the production site of the blow molding equipment may reach 50-60 degrees, while the temperature…

8 Points:Mold Testing of the Blow Molding Machine

mold testing

What Yankang Plastic Machinery going to share with you today is 8 points for attention during mold testing of the blow molding machine. It is necessary to do the mold testing before the new mold is blow-molded or when other molds are replaced on the machine. The test result will directly influence the follow-up production of the factory. Therefore, reasonable operation steps must be followed and useful technical parameters should be recorded in the process of mold testing to facilitate the mass production…
