Egg Tray Blister Forming Machine 220-480 Times / Hour 0.5-0.7 MPa
Principles of Vacuum Forming
The technology of Vacuum Forming is a method for thermo-forming. It
is a method of using thermoplastic sheet to make an opening of the
housing of the article. Cut the plastic sheet into special size
first, and then heat and soften the sheet through the huge pressure
difference on both sides of the sheet or mechanical pressure, this
can make the sheet attached with the surface of the mold after
heating and deforming, next through cooling and shaping, the sheet
can be vacuumed into various shapes of cover, plastic trays, bubble
The technology of vacuum forming relied on vacuum force which can
make the sheet achieve tensile deformation. Vacuum force is easy to
be realized, grasped and controlled, so it is the earliest, a
thermal forming method ,which is widely used currently.
Introduction of Vacuum Forming Machine
1. This machine is automatic. Just after placing plastic sheet onto
the frame, then heating, forming, cooling, can be done
2. The control board is near the operator, so it can be operated
easily, greatly improve the efficiency of production.
3. The far-infrared ceramic heating elements can control every
single block heater temperature, more power-saving features, and
reducing production cost.
4. The furnace is guided automatically.
5. The cooling system is independent by cold water.
6. This machine can form all kinds of blisters just replace mould.
This type machine can be used for plastic film for all kinds, such
as toys, hardware, food, electronics, medicine, with a transparent
film coating repacked in a board, form a seal packing.
This type machine can also produce plastic ceiling panel, cake
boxes, lunch boxes, automobile materials and sanitary materials
etc, which can be produced with three-dimensional relief pattern
like 3D advertisement products.
Suitable material: PVC, PET, PP, PC, ABS, PS, EPS, HIPS, LDPE, HDPE
and all thermoplastic sheet.
Working Processes of Vacuum Forming Machine
1. Independent temperature control system: Adopting dense, plate
and special far infrared ceramic heating brick to assemble the
machine. It can reach exact temperature within 5 minutes. Steady
temperature can assure high quality of product when use PVC,PET or
other environmental materials. Also, it can save more power that
traditional machine, using the time of cooling and demoulding after
forming to heat the material , so it will not influence the forming
2. Adopting solid-state temperature controller,which has
independent, automatic voltage regulator function, when the
external voltage changes in a range, it can ensure the stable
3. The electric furnace are equipped with cylinder to push, and it
has electromagnetic valve buffer system, so this can make the
electric furnace stable and durable
4. The machine has complete functions like“ delay vacuum, vacuum,
vacuum with the wind, Spray, cooling wind”, all these can make it
convenient and for workers to operate it accurately in actual
production, and ensure the perfect vacuum forming process in a best
time for high technology products.
5. Equipped with auto spray mold-release agent, the machine has two
functions: vibration demould and mold blowing, so this can make it
easy for formed sheet to release from the mold
6. Die die blowing function: die into the mold and blowing, make
the film formation or summon up, then forming a more perfect
7. Precise positioning function of clip, ensure the material placed
at the exact position
8. The cooing fan is controlled by inverter, volume of the wind can
be adjusted easily.
9. Quick die change function (Automatic Locking); Intelligent
temperature control system, servo mechanical transmission system,
imported electrical control system , etc.
Working Processes of Vacuum Forming Machine
Carry materials manually→ clamp the materials → move the material
into the oven,(while we can use blow function to keep material not
drop down), after the material to soft →take the material to
forming area → Bubble blow the material before vacuum (this is
important function) → the vacuum will auto start→ open the fan to
cold→ separate the model and material →take the material out.

Questions 08. What Should I bring when I visit your factory?
RE: For special product design and develop, we request you bring a
piece of testing material, you can test on our machines on-site.
For common product, it is enough to show us product pictures or
material together. However, when an HF-welded seam is stressed, the
load is absorbed by the material surfaces, which of course means
that the HF-welded seam is stronger. Furthermore, the seam created
with HF can be welded in a manner that provides a uniform
transition without splices between the joined materials. There is
no space through which dirt, moisture or bacteria can penetrate and
impair the product’s strength and durability.
