Tips for Transparent Plastic Blow Molding Processing: Methods for Distinguishing Rolling Molded Water Tanks and Blow Molded Barrels

Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. The tubular plastic preform obtained by extrusion or injection molding of thermoplastic resin is placed in a split mold while it is hot (or heated to a softened state). After the mold is closed, compressed air is immediately introduced into the preform to blow and expand the plastic preform tightly against the inner wall of the mold. After cooling and demolding, various hollow products are obtained.

The production steps of plastic water tanks

Explanation of the steps for making plastic water tanks: Plastic water tanks are processed using synthetic material polyethylene (HDPE), and the commonly used methods for making plastic water tanks can be roughly divided into two categories: Type 1: Rotational molding production method, one-time molding

The bearing range of plastic water tanks and storage tanks

The advantages of water tanks (storage tanks, water towers) are well-known: wide temperature range, non-toxic, odorless, anti extension, anti penetration, impact resistance, and corrosion resistance. Therefore, they are widely used in industries such as food, daily use, chemical, household, agriculture, machinery, and medicine. However, even the best water tank has its load-bearing range, which we must pay attention to.

Precautions for the installation of plastic water tanks

1、 Installation environment: When installing a plastic water tank, it should be in a horizontal position and able to withstand the weight when the tank is filled with water; Due to the protrusion of the bottom of the water tank towards the box during production, an appropriate amount of fine sand can be used to fill the bottom during installation, increasing the load-bearing capacity of the bottom of the water tank; The temperature around the water tank cannot exceed the limit range of cold and heat resistance of the water tank.

The reasons for fading of blow molded products

Also known as hollow blow molded products, a rapidly developing plastic processing method. The tubular plastic preform obtained by extrusion or injection molding of thermoplastic resin is placed in a split mold while it is hot (or heated to a softened state). After the mold is closed, compressed air is immediately introduced into the preform to blow and expand the plastic preform tightly against the inner wall of the mold. After cooling and demolding, various hollow products are obtained. The manufacturing process of blow molded film is very similar to that of hollow products in principle, but it does not use molds. From the perspective of plastic processing technology classification, the forming process of blow molded film is usually included in extrusion. We often find that blow molded products may fade more or less after long-term storage, so why do blow molded products fade? Let's explain to everyone the reasons for the fading of blow molded products.
