Polypropylene for Thermoforming and Injection Molding

At Advanced Plastiform, Inc. we design and manufacture custom plastics for industries and businesses across the Southeast and Mid-Atlantic. In order to ensure that we are producing highly-durable plastics that can fulfill the needs of our customers, we work with numerous thermoplastic materials to provide the best result. Due to its versatility and multitude of uses, we are a leading polypropylene plastic manufacturer.

What Is Polypropylene?

Polypropylene is a thermoplastic polymer that is one of the most widely used plastics worldwide, second only to polyethylene. It was created in 1951 by petroleum chemists and was quickly used in large-scale commercial production.

Because it has a unique chemical makeup, it offers the following qualities:

  • PolypropyleneA high melting point
  • Low water absorption
  • Chemical resistant
  • Highly flexible
  • Food safe
  • Low electrical conductivity.

In addition to its versatility, it’s also one of the lowest cost plastics, making it a popular option for mass producing plastics across the automotive, furniture, and material handling industries.

Polypropylene Thermoforming

Polypropylene thermoforming is a lower-cost, efficient way to manufacture large plastic goods and components. We heat the polypropylene until it is malleable, then fit it around a custom tool and finish the product using one of three methods:

Vacuum Forming

Vacuum forming is the simplest method of polypropylene thermoforming. Once the plastic is heated and fitted around the custom tool, a high-powered vacuum removes air and draws the plastic more tightly against the tool. This method is best for plastic components that don’t require sharp edges, defined corners, or intricate details, such as car dashboards and shipping trays.

Pressure Forming

Often used as a less expensive alternative to polypropylene injection molding, pressure forming plastics allows us to achieve higher levels of detail and sharp edges than with vacuum forming. Once the polypropylene is fitted around the tool, the plastic is blasted at high pressure with air, pushing it against the tool and creating the sought after design and detail. Because it’s low electrical conductivity, polypropylene pressure forming is used for manufacturing scientific instruments and medical equipment.

Twin-Sheet Forming

Twin sheet forming is a complex method of polypropylene plastic manufacturing, requiring high levels of precision and care. It involves heating two plastic sheets at the same time, then fitting them together and fusing them. Because the plastic must be matched with pressed points where the fusion occurs, there’s no room for error or the integrity of the product is weakened. Twin sheet forming is ideal for manufacturing double-walled and hollow products, like air ducts, chutes used in material handling, and bed liners.

Polypropylene Injection Molding

Polypropylene injection molding is a method of manufacturing in which polypropylene is melted to its liquid state, then injected into a double-sided mold. Injection molding is ideal for small components and parts or plastic pieces that require intricate detailing and varying thickness throughout the item. While the up-front cost is more expensive and has a longer lead time than thermoforming, for high volume orders or orders that will be fulfilled regularly, the per-unit cost is actually very cost efficient.

What Is Polypropylene Used For?

It’s not much of an exaggeration to say polypropylene is used for everything. It’s easy to customize, has a high melting point, high flexibility, and is water resistant so it’s most commonly used for:

  • Food packaging and containers
  • Plastic cooking tools
  • Electronics packaging
  • Electronics panels and housing
  • Items requiring “living hinges” that can bend frequently without breaking, like ketchup lids and to-go containers.
  • Car batteries
  • Laboratory equipment
  • Carpeting and rugs
