Polyvinyl Chloride for Thermoforming and Injection Molding

At Advanced Plastiform, Inc., we work with companies across the Southeast and Mid-Atlantic states, designing and manufacturing custom plastics for all types of use - from car bumpers and trunk liners to medical trays and packaging. In order to provide the best outcome for each individual product, we have a wide variety of thermoplastic materials available to use, but one of the most common plastics we use is polyvinyl chloride, more commonly known as PVC. In fact, PVC is one of the most commonly used plastics in the world.

What Is Polyvinyl Chloride?

Polyvinyl chloride is a thermoplastic polymer that can be heated and shaped for a multitude of materials. PVC in its pure state is highly rigid and brittle, but by adding plasticizers or phthalates, it can be softened, often taking the place of rubber, or blended with cotton to make canvas.

Polyvinyl Chloride

PVC is highly durable and offers excellent resistance chemical damage, water and moisture, and abrasion. Because it’s so versatile and can be blended with a variety of additives to change its properties from extremely rigid to soft and flexible, it’s commonly used in thermoforming, while its dimensional stability and low melting point makes it ideal for injection molding.

Polyvinyl Chloride Thermoforming

To create large plastic products and components, we often use polyvinyl chloride thermoforming, which involves heating the PVC to where it’s soft and flexible, then fitting it around a custom tool to create the ideal shape and design. Both affordable and efficient, our polyvinyl chloride manufacturing company uses three different types of PVC thermoforming methods to ensure the best results while providing lower costs and faster lead times to our customers.

Vacuum Forming

Vacuum forming is the most basic method of polyvinyl chloride thermoforming in which the PVC is heated to a malleable state, then fitted to a custom tool. Then, a highly powered vacuum is fitted between the tool and plastic, removing all air from between the two and pulling it snugly against the tool, creating an accurate shape. This method is best for larger products where high levels of detail or sharply defined corners aren’t necessary. In fact, polyvinyl chloride vacuum forming is used for things like bathtubs and shower trays.

Pressure Forming

For more intricate detailing and a less expensive alternative to polyvinyl chloride injection molding, we use pressure forming. Like vacuum forming, we fit heated PVC around a tool, but then, we use highly pressurized air to blast the plastic, pressing it firmly against the tool, creating sharp edges and corners and high levels of detail for construction materials and other products.

Twin-Sheet Forming

Polyvinyl chloride is most widely known for the rigid PVC pipe used in plumbing and water infrastructure systems. To create pipes and other hollow tubes such as air ducts, we use twin sheet forming. Twin sheet forming is the most complex polyvinyl chloride thermoforming method because it requires two sheets of plastic to be heated and shaped at the same time, then fitted and fused together. There is no room for error as the plastic must be matched precisely at pressed points in order to join together properly.

Polyvinyl Chloride Injection Molding

For smaller plastic components and parts, or parts that require high levels of detail or varying thickness, we use polyvinyl chloride injection molding. This is a more intensive method of plastic manufacturing because it requires designing a double-sided mold made from steel, aluminum, or copper alloy. Then, the PVC is melted to a liquid state and injected into the mold, creating a detailed, highly accurate finished shape that is either ready for painting or customization or to be packaged and sent to our customers.

What Is PVC Used For?

Both rigid PVC and flexible PVC have a wide variety of uses. While most people equate it with PVC pipe and other construction materials, it’s also the plastic used in vinyl siding, window frames, and roof lining. In fact, it’s used in virtually every industry to make things like:

  • Shower curtains
  • Packaging, including bottles, blister packs, and shrink wrap
  • Garden hoses
  • Cable and wire insulation
  • Flooring and wall coverings
  • Medical tubing and IV bags
  • Raincoats and rainboots
