What is Bathtub Forming Machine?

A bathtub forming machine, also known as an acrylic bathtub vacuum forming machine, is a specific machinery used to make acrylic bathtubs by vacuum-shaping heated sheets. Vacuum forming is the technique of heating a sheet until it is malleable, laying it over a mold, and then sucking the material firmly against the mold with the help of a vacuum to shape it into the shape of the mold. Due to its lightweight nature, durability, and ease of shaping into many designs, acrylic is a common material for bathtubs.

Romas is a professional manufacturer of acrylic bathtub vacuum-forming machines. We produce high-precision machines.

Working Principle

A vacuum-forming process is the basis of the bathtub-forming machine’s functions. The machine uses heat to make a plastic sheet malleable, which is then placed over a mold and suctioned securely against the mold. The plastic hardens as it cools, molding itself to the form of the mold. The formed bathtub is then taken out of the mold and prepared for quality control and finishing.

Your Guide To Vacuum Forming!

Vacuum forming has been used for nearly a century to make many of the products we see and use daily. From grocery store items to car parts, vacuum-formed components are all around us. But how are they made – and how is 3D printing making them better?

Vacuum forming is a type of thermoforming in which heat is used to form a design. Thermoforming processes include vacuum forming, pressure forming, and twin sheet forming. Each of these processes uses a mold or mold to shape heated sheets of plastic into the desired form.

Pressure-forming methods require that the plastic sheet be pressed between two molds and then heated to assume the shape. Two plastic sheets are heated and fused together in twin-sheet forming to form double-walled or hollow parts.

Vacuum forming is the simplest of the thermoforming methods, using only one mold at a time. As the name might indicate, vacuum forming relies on a vacuum, as suction applied to the heated plastic sheet will draw it around the mold to create the appropriate contouring.

The vacuum forming process comprises a few relatively straightforward steps:

  1. Clamp a plastic sheet in a frame
  2. Heat the plastic sheet to the point the plastic is workable – soft enough to take on a new shape, but not heated to the point of melting or losing its integrity.
  3. Apply vacuum to pull the plastic around the mold, shaping the heated sheet to the desired contours.
  4. Allow the plastic to cool before removing it from the mold. This may be expedited for large pieces using fans or cool mists.
  5. Trim excess plastic and smooth edges to final part quality.


Different plastics used in the thermoforming process are applicable for different uses. For a clear plastic salad box, you wouldn’t need the same high-impact strength as you would for an outdoor sign, while a car bumper still needs more durability. Below is a list of plastic that is highly preferred for the thermoforming process:

  1. Polypropylene (PP)
  2. Polycarbonate (PC)
  3. ABS (Acrylonitrile Butadiene Styrene)
  4. High-density polyethylene (HDP)
  5. Polystyrene (PS)
  6. Polyvinyl chloride (PVC), and more.

Some applications of vacuum forming thermoforming machines are listed hereunder:

  1. Advertising equipment, light box, acrylic sign, logo, etc
  2. Decoration equipment
  3. PC industry
  4. Album production
  5. Packing industry
  6. Auto appliance industry, and more.

Vacuum Forming’s Benefits

A vacuum forming machinery , a single or double heating component, a frame for retaining the plastic, a movable work piece for holding the equipment and pattern needed to create the shape of the item you want to create all go into a vacuum forming machine. While some machines require manual operation, others are semi- or fully automatic.

A manufacturing technique for molding plastic items is vacuum forming. Vacuum forming is utilized in a broad variety of manufacturing processes, from the production of small custom parts on desktop computers to the production of massive parts on automated industrial machines.

Vacuum Forming Benefits

Vacuum forming is a popular choice among industrialists, developers, and other professionals. Vacuum forming has several advantages, such as:


Vacuum forming is usually less expensive to produce than other manufacturing processes, especially for small product lines. Vacuum forming is more affordable in large part because tooling and prototyping are less expensive. Manufacturing for vacuum forming can be two to three times less expensive than manufacturing for injection molding, based on the surface size of the components being created and the sizes of the fasten frame.

Transition Period

Because tooling can be produced more quickly, vacuum forming has a short reaction time than other methods of production. The time needed to make vacuum forming tools is typically half that required to create injection molding tools.


Designers and manufacturers can experiment with new ideas and create prototypes with vacuum forming without incurring significant costs or delays. Compared to other production procedures, molds can be replaced out or altered more effectively.

Additionally, vacuum forming enables designers to provide buyers with a wider range of color options and customization. This provides many companies the option to provide customers with one-of-a-kind patterns and create personalized products at a reasonable price.

Making materials fit for human consumption

Vacuum forming is frequently used by producers to create food-grade containers and components for the medical sector because it works well with polymers that can be sanitized or maintained free of impurities. To produce parts that can endure sterilization procedures and adhere to strict medical and/or pharmaceutical criteria, vacuum forming employs medical-grade polymers.
