Plastic thermoforming can use different types of techniques that have different advantages and disadvantages. Some of the most common types of plastic thermoforming are:
Vacuum Forming
Vacuum forming uses heat and pressure to draw plastic sheets into its final configuration. First, A sheet is heated and placed over a mold, where a vacuum manipulates it into the desired shape. When the material is detached from the mold, the final result is a precise shape.
Vacuum forming is simple, fast, and cost-effective. It can produce parts with good detail and surface quality. However, it can also result in uneven thickness, webbing, and bubbles in the sheet.
Pressure Forming
Pressure forming is similar to vacuum forming but benefits from added pressure. The process also involves heating a sheet of plastic and also adds a pressure box to the non-mold side of the sheet. The pressure box creates up to 60 pounds per square inch (PSI) of air pressure, in addition to the vacuum on the mold side.
Pressure forming can produce parts with injection-molded quality but lower tooling costs. It can create sharper detail and better definition in the sheet. However, it also requires more complex equipment and higher cycle times.
Mechanical Forming
Mechanical forming involves the use of a direct mechanical force to shape the preheated plastic sheet. A plug or a stamp pushes the sheet into or onto a mold to create the desired form.
Mechanical forming can produce parts with uniform thickness and complex shapes. However, it also requires more force and higher tooling costs.
Vacuum forming and pressure forming are two types of plastic thermoforming techniques that have different advantages and disadvantages. They both involve heating a plastic sheet and forming it using a mold, but they differ in how they apply pressure or vacuum to the sheet.
Vacuum Forming
Vacuum forming uses a vacuum to suck the plastic sheet into or over the mold. This technique is simple, fast, and cost-effective. It can produce parts with good detail and surface quality. However, it can also result in uneven thickness, webbing, and bubbles in the sheet.
Pressure Forming
Pressure forming uses compressed air to push the plastic sheet into the mold. This technique can produce parts with injection-molded quality, sharper detail, better definition, and tighter tolerances than vacuum forming. However, it also requires more complex equipment and higher cycle times.
Vacuum forming uses negative tooling, while pressure forming uses positive tooling. This means that vacuum forming creates parts with more detail on the inside surface, while pressure forming creates parts with more detail on the outside surface.
here is a table that summarizes the differences between vacuum forming and pressure forming:
| Feature | Vacuum Forming | Pressure Forming |
|---|---|---|
| Pressure/Vacuum | Vacuum only | Vacuum and compressed air |
| Cost | Lower | Higher |
| Cycle time | Faster | Slower |
| Equipment | Simpler | More complex |
| Part quality | Good | Better |
| Part detail | Good on inside surface | Better on outside surface |
| Part thickness | Uneven | Uniform |
| Part defects | Webbing, bubbles | Fewer |
There are some design considerations that need to be taken into account when designing parts for plastic thermoforming. Some of the main design considerations are:
Draw Ratio
Draw ratio is the ratio of the surface area of the part to the footprint of the part. It determines the minimum starting gauge of the plastic sheet to achieve the desired final thickness. The higher the draw ratio, the thinner the part will be.
Material Thickness
Material thickness is the thickness of the plastic sheet before and after thermoforming. It affects the strength, stiffness, and appearance of the part. The material thickness should be chosen based on the part requirements and the draw ratio.
Draft Angles
Draft angles are the angles between the vertical walls of the part and the mold surface. They facilitate the removal of the part from the mold and prevent sticking or tearing. The draft angles should be as large as possible, typically between 3° and 5°.
Detail
Detail is the level of complexity and definition of the part features, such as corners, edges, textures, logos, etc. It depends on the type of thermoforming technique used, such as vacuum forming or pressure forming. Pressure forming can produce more detailed and complex shapes than vacuum forming.
Undercuts
Undercuts are features that extend beyond the vertical walls of the part, such as snaps, hooks, ribs, etc. They increase the functionality and aesthetics of the part, but they also complicate the mold design and removal. Undercuts can be achieved by using movable mold inserts or secondary operations.
here is a table that lists the design considerations for plastic thermoforming:
| Design Consideration | Description | Example |
|---|---|---|
| Draw ratio | The ratio of the surface area of the part to the footprint of the part | A part with a surface area of 3,744" and a footprint of 1,728" has a draw ratio of 2.17 |
| Material thickness | The thickness of the plastic sheet before and after thermoforming | A part with a desired final thickness of 0.150" and a draw ratio of 2.17 requires a minimum starting gauge of 0.330" |
| Draft angles | The angles between the vertical walls of the part and the mold surface | A part with a draft angle of 5° has less risk of sticking or tearing than a part with a draft angle of 2° |
| Detail | The level of complexity and definition of the part features | A part with sharp corners, textures, and logos has more detail than a part with smooth and simple surfaces |
| Undercuts | Features that extend beyond the vertical walls of the part | A part with snaps, hooks, or ribs has undercuts that need movable mold inserts or secondary operations |
It has many advantages, such as low tooling costs, fast production times, large part capability, and design flexibility. However, it also has some challenges or limitations, such as:
Material Waste
Thermoforming involves trimming the excess material from the formed part, which can result in material waste and disposal costs. The trimmed material can be recycled or reused, but it may require additional processing or equipment.
Part Thickness Variation
Thermoforming involves stretching the plastic sheet over a mold, which can cause uneven thickness distribution in the part. The part may be thinner in areas with deep draws or complex shapes, and thicker in areas with less stretching. This can affect the strength, stiffness, and appearance of the part.
Part Size and Shape Limitations
Thermoforming can produce large parts, but it also requires large sheets of plastic and large molds, which can increase the cost and complexity of the process. Thermoforming can also produce complex shapes, but it may require special techniques or secondary operations to achieve features such as undercuts, holes, threads, etc.
Material Selection
Thermoforming can use various types of thermoplastic materials, but not all materials are suitable for thermoforming. The material must have good formability, stability, and durability under heat and pressure. Some materials may have issues such as warping, sagging, cracking, or bubbling during thermoforming.
here is a table that lists the challenges or limitations of plastic thermoforming:
| Challenge or Limitation | Description | Example |
|---|---|---|
| Material waste | The excess material that is trimmed from the formed part and needs to be disposed or recycled | A part with a large footprint and a small surface area may have a lot of material waste |
| Part thickness variation | The uneven thickness distribution in the part due to stretching the plastic sheet over the mold | A part with a deep draw or a complex shape may have thinner areas than a part with a shallow draw or a simple shape |
| Part size and shape limitations | The cost and complexity of producing large parts or parts with complex features using thermoforming | A part that is too large for the available sheet size or mold size may need to be split into multiple parts or use a different process |
| Material selection | The suitability of different thermoplastic materials for thermoforming based on their formability, stability, and durability under heat and pressure | A material that has poor heat resistance or formability may warp, sag, crack, or bubble during thermoforming |
Here is a table that lists the differences between plastic thermoforming and other plastic manufacturing processes
| Process | Production Volume | Tooling Cost | Part Size | Part Complexity | Part Quality | Material Selection |
|---|---|---|---|---|---|---|
| Plastic Thermoforming | Low to medium | Low | Large | Simple to moderate | Good detail and surface quality; uneven thickness; webbing; bubbles | Various thermoplastics; limited by formability; stability; durability |
| Injection Molding | High | High | Small | Complex | Uniform thickness; high precision; warping; shrinkage; flash | Wide range of thermoplastics; including difficult or impossible to thermoform |
| Blow Molding | High | High | Small to medium | Moderate to complex | Uniform thickness; good surface quality; warping; shrinkage; flash | Wide range of thermoplastics; including difficult or impossible to thermoform |
plastic thermoforming can be environmentally friendly, as it has some benefits such as:
Material Efficiency
Thermoforming can use various types of thermoplastic materials, some of which are biodegradable or compostable, such as PLA, PHA, or starch-based plastics. Thermoforming can also use recycled or post-consumer plastics, such as PET, HDPE, or LDPE. Thermoforming can reduce material waste by using precise sheet sizes and efficient mold designs.
Energy Efficiency
Thermoforming uses less energy than other plastic manufacturing processes, such as injection molding or blow molding, as it only heats the plastic sheet to a pliable temperature, rather than melting it to a liquid state. Thermoforming also uses less pressure than injection molding or blow molding, which reduces the energy consumption and carbon footprint of the process.
Product Durability
Thermoforming can produce parts that are durable and have a high degree of structural integrity, which helps to protect them and their contents from the effects of weather and other environmental factors. Thermoformed parts can last longer and require less maintenance or replacement than other plastic parts, which reduces the environmental impact of the product life cycle.
