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
This production method is very simple. First, design the drawing of the water tank, set up a model of the water tank according to the shape, size, and size on the drawing, process it, and form it in one go. This production method mainly produces plastic wine jars, plastic drums, and plastic storage tanks, Large plastic water tanks such as PE dosing boxes.
Type 2: Main production methods of blow molding
The water tanks produced by these two production methods are generally smaller in volume and can be mass-produced.
Plastic water tanks are made from synthetic material polyethylene (HDPE), and our household plastic wrap is also made from it. Polyethylene is relatively environmentally friendly and resistant to high and low temperatures, so it will not pose a safety hazard to our bodies. Secondly, in the past, we mostly used iron plastic water tanks, but over time, iron will oxidize and rust, posing a certain degree of safety hazard to the water source.

Transparent plastic blow molding processing tips
In mold planning, attention should be paid to the following issues (including product planning) in order to avoid poor plastic molding caused by poor activity or uneven cooling, resulting in appearance defects and transformation. Generally, in mold planning, the following points should be noted:
The manufacturing process of transparent plastics
（1） The preparation and dryness of materials can affect the clarity of goods due to the presence of any impurities in plastic, thus affecting storage and transportation. During the feeding process, it is necessary to pay attention to sealing to ensure the cleanliness of the material. Especially when the material contains moisture, heating can cause the material to transform, so it must be dry, and it is necessary to use a dry hopper when adding materials during injection molding. It should also be noted that during the dry process, the input air should be filtered and dehumidified to ensure that it does not contaminate the material. The drying technology of Tongming Plastics: Data \ Technology Drying temperature (℃) Drying time (h) Material layer thickness (mm) Whitening PMMA70-802-430-40pc120-130>6<30 Choose hot air circulation drying PET140-1803-4 Choose continuous drying feeding equipment is preferred.
The blow molding process of transparent plastics
Due to its high light transmittance, Tongming plastic must have strict requirements for the appearance quality of plastic products, without any spots, pores, or whitening. Mist halo, black spots, discoloration, and poor gloss are the drawbacks that affect the quality of materials and equipment throughout the entire blow molding process.
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 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.
