Ways Vacuum Molding Can Help Your Industrial Business

 

1. Vacuum Molding Promotes Rapid Production

Prototypes or sample smaller product versions are rapidly produced with vacuum molding, with detailed parts similar to the full-sized version. For low volume or short-run manufacturing, vacuum forming can be an indispensable tool in creating high-quality plastic components.

 

So, how does the vacuum molding process work? Plastic vacuum molding involves heating an extruded flat plastic sheet until pliable, which is thereafter shaped by vacuum application (3D shape). Once the mold has cooled down and hardened, you’re able to trim the plastic part into your desired profile.

 

Here’s the step-by-step process of vacuum molding:

  • Clamping: The plastic sheet must be firmly held so the clamp frame should be powerful enough during the molding process. It should have the capability to handle the thickest material on the machine. Using an automated process is important so moving parts are properly guarded and interlocked. It will prevent accidental damage. Also, a safety guard is required for safe machine operation.
  • Heating: Infra-red elements are used in heating the material, which is mounted in a reflector plate made of aluminum. Obtain the best vacuum molding results through uniform heating. You can use any material with vacuum molding and heat the entire surface uniformly. Sophisticated quartz heaters have a lesser thermal mass than other heaters for a quicker response time. Twin heaters (pyrometers) are recommended when molding thicker materials because they provide faster cycle times and more even heat penetration. If you want to form high-temperature materials, twin quartz heaters are recommended.
  • Vacuum: After the material is pre-stretched, you can apply a vacuum in assisting with forming the sheet. To draw trapped air between the mold and the sheet, a vacuum pump should be used. A large machine vacuum reservoir can be used with a vacuum pump that has a high volume capacity. It enables two vacuum stages to ensure rapid forming before the temperature of the sheet drops below the ideal molding temperature.
  • Cooling and Release: These processes are not available on all vacuum molding machines. The plastic should be cooled down before being released because releasing it too soon may result in a rejected part. You can use fans once the part or desired product is formed for a rapid cooling cycle.

 

2. Versatile and Cost-Effective Plastic Molding Alternative

When manufacturing parts, there are many options available such as injection molding. However, if you want a versatile and cost-effective molding alternative, vacuum molding is a better option.
