Used in all types of industries, plastics provide versatility and strength across a wide range of applications, from automotive body parts to human body parts. Each application requires a special manufacturing process that can mold the part based on specifications.

While thermoforming is commonly used for large-scale designs and shorter production runs, injection molding tends to be a better choice for small, intricate parts and large production runs.

What Is Thermoforming?

Thermoforming is the process of forming a heated plastic sheet to the surface of either a male or female mold. This is a single-sided plastic fabrication process, unlike injection molding; only one side of the plastic sheet is controlled by the mold or tool. Vacuum forming and pressure forming are both popular styles of thermoforming.

Depending on a project’s needs, thermoforming can offer several distinct advantages, including: 

  • Lower tooling costs compared to injection molding
  • Quick product development and prototyping
  • Bright color and texture options
  • Extreme adaptability and simple adjustments

Thermoforming is ideal for smaller production quantities (250 to 3000 parts per year).

What Is Injection Molding?

Crafted from stainless steel or aluminum, split-die molds are injected with molten liquid polymers at high temperatures under extreme pressure. The molds are then cooled to release complete plastic parts. 

Plastic injection molding offers several distinct advantages of its own, including:

  • Detailed, highly engineered tooling with multi-cavity mold options
  • Precise, efficient processing for large volumes of small parts
  • Effective reduction of piece count 
  • Efficient material use and low scrap rates

Plastic injection molding is ideal for large-volume orders and mass production in projects requiring thousands or even millions of the same part.
