Question: What is Thermo-molding?

Answer: Thermo-Molding, Thermo-Forming or Vacuum Molding is a manufacturing process where a sheet of plastic is heated to a pliable temperature and formed to a specific shape in a mold and then trimmed to create the desired product. The sheet of plastic is heated in a large oven to a high enough temperature that permits it to be stretched into or onto a mold, a vacuum is used to draw the plastic tight to the mold and then allowed to cool.

Question: Are there other types of molding?

Answer: Yes, there other types commonly known as injection molding, blow molding, and rotational molding. However, here at Custom Molding Services, we use the thermos molding process.

Question: Does Custom Molding Services believe in recycling?

Answer: Absolutely. At Custom Molding Services we believe that this earth is here for us to use, not abuse. We want to leave a beautiful planet for generations to come. We recycle every bit of scrap that we can to do our part.

Question: What types of thermos-molding molds are there?

Answer: There actually serveral, the most common are:

  • Wood Molds- Wooden molds are usually the first stage in the thermos-molding project. They are usually somewhat inexpensive and allow the customer/manufacturer to make simple changes to their design. Once the final wood mold is completed it is sent to a mold maker where a ceramic composite or an aluminum mold is cast. Here at Custom Molding Services, we use the aluminum version.
  • Cast aluminum molds- these are cast out of aluminum at a foundry. They normally have temperature control lines running through them. The temperature control lines aid in regulating the heat of the plastic while being processed.
  • Machined Aluminum Molds-these these are like the above molds but are made of a solid block of aluminum using a CNC machine.
  • Composite Molds- there are made from resins, depending on application, they have been known to produce quality parts especially on high volume production.
  • Question: What types of material do you use?

    Answer: We only produce products made from plastic or plastic variations. We do however make other accessories or parts to accompany the plastic part.

    Question: How durable is the material you use?
