Custom PVC Injection Molding
PVC is a commonly used industrial thermoplastic to make various plastic goods such as pipes, siding, and flooring. Its weatherability and strength make it suitable for various projects.
What is PVC Material?
This material, which is mainly white, can be brittle if subjected to additional plasticizers. It was first used during the 1920s. It can be molded in two different forms, namely, rigid and flexible. The former is commonly used for flooring and insulation, while the latter is used for replacing rubber. The former is mainly used for construction projects. The rigid form of PVC is commonly used for construction projects such as water distribution pipes and machine housings.
PVC Material's Characteristics
Due to PVC properties, such as its high density and excellent chemical resistance, it has been widely used in the industrial market. This material is also budget-friendly and can be molded into various shapes and sizes with ease. Its durability makes it an ideal choice for various industrial projects. Like other plastics, it can be molded into various shapes and sizes through injection. Also, its easy recycling makes it a good choice for various industrial projects.
Processing PVC Injection Molding
The basic process of making PVC involves melting the plastic pellets into a moldable state. The temperature at which the plastic should be molded should be set to avoid extreme decomposition. After reaching this temperature, the plastic is injected into a mold that's made up of two parts. The resin will gradually harden once it's molded into the part. The two sides of the mold that are exposed to the air are then ejected to allow the plastic to cool. Usually, the resin in PVC is around a percent. The part that's molded first goes through a cooling process, which releases the other parts of the mold. The process then switches to a new set of steps. Although its shrinkage can vary depending on several factors, such as the resin's hardness, the temperature, and the additives used, TEAM MFG can provide a reliable and cost-effective solution.
By choosing PVC injection molding, you can use your existing mold several times and still produce high-quality parts. This method is more cost-effective and produces better results than other methods.

Specifications of Injection Molding PVC
PVC is a thermoset material that can be used for injection molding. It can be heated to a temperature of 500 degrees Fahrenheit and then cooled. Various additives are also commonly used to improve its properties.
● Melting temperature: 320-428◦F
● Mold temperature: 68-158◦F
● Injection speed: slow to avoid degredation
● Tensile strength: 6,500 psi
● Packing pressure: up to 100MPa
● Drying temperature 75-90◦F
● Low shrinkage: 0.002 – 0.006 mm/mm or 0.2 – 0.6%
Injection Molding Polyvinyl Chloride (PVC) Process
In powder or pellets form, the heated plastic is fed down a barrel. A plasticizer is added to improve the plastic's fluidity and prevent it from clumping. The finished product is then injected into a custom mold with two sides. After the plastic has cooled, it is injected into a customized mold with two sides. The finished product is then dropped from the injection molding machine and is processed for any finishing touches.
Injection Molding PVC Applications
Various industries such as food, beverage, and packaging have started using PVC in their products. Some of these include bottles, dashboards, and packaging.
● Automotive parts
● Packaging
● Bottle caps
● Wire spools
● Pocket combs
● Plumbing
● Parts for construction
● Window handles
