PVC hose is a very common pipe in daily life. It has the characteristics of soft, light weight, good feel, colorless and smooth, etc. At present, it is widely used in life and industry. The market has a lot of demand.This article will introduce the PVC pipe manufacturing process.

Brief description of the PVC pipe manufacturing process:

PVC Hose

Step 1: Raw Materials Preparation
The first step in the production process of PVC hose is the preparation of raw materials. PVC resin, plasticizers, stabilizers, lubricants, and other additives are required to make PVC hoses.
Step 2: Mixing
Once the raw materials are prepared, they are mixed together in a high-speed mixer. The mixer blends the ingredients until a homogeneous mixture is formed. The mixing process is crucial as it determines the quality of the PVC hose.
Step 3: Extrude granulation
This process to control the temperature, the material temperature to the high point should be controlled at higher than the melting temperature of the material, lower than the extrusion molding temperature, that is, between 155~160℃. The purpose of granulation is to achieve full mixing and initial plasticizing. The temperature of each area of the granulator is as follows, 80~90℃ in one area; 130~140℃ in Zone 2; The third zone 140~150℃; The nose is 150~160℃.
Step 4: extruded tube forming
The temperature of extrusion molding should be slightly higher. Generally speaking, the transparency of the pipe is related to the molding temperature. In a certain temperature range, high temperature transparency is good, and vice versa. At the same time, traction speed and cooling speed will affect the transparency of the pipe. The traction speed is slightly larger, the cooling speed is fast, the transparency of the pipe is better, and the traction speed is generally 10%~ 15% faster than the extrusion speed. After forming, the PVC hose needs to be cooled. It will be sprayed with cold water at the die of the head first, and then entered the water tank for cooling and forming.
Step 5: Cutting and Packaging
Once the PVC hose is extruded and reinforced, it is cut to the desired length and packaged. The PVC hoses can be packaged in coils or reels, depending on the customer’s requirements.
Step 6: Quality Control
Before the PVC hoses are released for sale, they undergo rigorous quality control checks. These checks ensure that the PVC hoses meet the required standards and specifications. Some of the quality control checks include testing the pressure rating, checking for leaks, and ensuring the PVC hose is free from defects such as air pockets or weak spots. The quality control process ensures that the PVC hoses are safe and reliable for their intended applications.
