2. MACHINE’S FUNCTIONS AND FEATURES
Basic Features
Our machine can be used to vacuum mould raw plastic sheets to form plastic
packaging used for toys, hardware, food, electronics, medicines, etc. It can also be
used with clear plastic sheets to form airtight plastic packaging.
In addition, our machine can also produce materials with embossed designs, used
frequently for ceiling tiles, biscuits boxes, rice boxes, automobile accessories and
health products, etc.
Main Features
1. High speed continuous forming procedure is as below:
(1) Plastic sheet (raw material) on material feeding stand  (2) Heating 
(2) Moulding / Shaping, Cooling, Release from mould  (4) Cutting
2. Independent Grouped Temperature Control; equipped with special flat “far infrared ceramic” heating mechanism, which produces even temperature and is 50% more
energy economical than conventional heaters. And by starting the heat-up during the
product cooling process, the heat-up will not interfere the total vacuum forming
processing time.
3. Heating furnace is equipped with manual switch to control vertical lifting and
lowering of the heating furnace. Thick plastic sheets can be heated by dual heating
furnaces on the top and bottom (can be separately ordered by customers) so as to
shorten heating time and increase production speed.
4. Plastic sheet feeder is made of dual needle chain, which can rotate at a high speed
but at the same time ensuring accuracy and stability of the grip. It is equipped with
width adjustment device which allows the machine to use plastic sheets to their
maximum width so as to reduce wastage of material.
3. MACHINE STRUCTURE AND LOGIC
Our machine structure is made up of these various major parts:
i. Release Stand, ii. Machine Main Body, iii. Material Feeding Stand, iv. Heating
Furnace, v. Mould Setting Plate, vi. Compressed Air Vacuum System, vii. Cooling
Water Spraying System, viii. Cutting / Separating section, ix. Furnace Temperature
Meter Box, x. Machine Control Box, xi. Timer Control Box
A. Release of Sheet: Operate by motor movement to connect switch.
B. Main Body: Is made from high quality steel to form the main structure of the
machine. Furnace, mould plates, vacuum box, furnace temperature meter box,
machine control box, cooling system and other important parts of the machine must
be handled with care during delivery. Hard knock or drop must be avoided during
delivery.
C. Material Feeding Stand: Is guided along dual needle chains, moved by chain
wheels which in turn are moved using compress air pumps. Working procedure is:
Heating plastic sheet  Desired temperature reached  Heated sheet has been prefitted along dual needle chains  the needles will fit into needle holes on the rotating
4
chain  wheels moved by compress air pump  this will form the movement of the
plastic sheet.
1. The length of the material to be vacuum formed can be easily controlled and preset
using the machinery control, to cater for different needs at different time. There are
two setting, setting 1 & setting 2, to adjust the material’s length.
2. As the process is repetitive, there is a Stop button in front of the material feeding
stand. This will enable you to perform a stop whenever the required quantity has been
reached and prevent further material wastage.
3. Material feeding is one of the most important step, and the step that requires the
most attention. The condition of the material being set on the material feeding stand
will directly affect the grip on the plastic sheet, which will then affect the quality of
the end product. Air-cooling pipes are laid on each side of the material feeding chain
and gripping panels so that they will not be deformed by the furnace when the furnace
is heating the plastic sheet. (special note to ensure the furnace is not at the heating
position when machine is shut down). The gripping panels and chains can be adjusted
to cater for different width of plastic sheets. (instruction for adjustment of width will
be discussed below)
4. There are 2 shiny metal bars in front of the material feeding stand where you will
load the plastic sheet roll. The metal bars are free-spinning but their own weight will
provide certain degree of restrictions when spinning. This simple logic will ensure
tight feeding when sheet are sent to the furnace and prevent bad forming due to
uneven feeding.
5. Feeding material section install with two rubber rollers, in between consist of three
adjustable alloy sheet to convey plastic sheet smoothly.
6. End section consist of two special design metal plate enable plastic sheet to release
in good condition.
7. In the process of material feeding, there is a door in between the mould and
furnace, in which the door will be open during heating……………
D. Heating Furnace
1. Our furnace are equipped with specially imported flat “far infra-red” ceramics.
There are a total of 57 such ceramic heaters, divided into 27 individual groups which
the temperature of each group can be manually adjusted by adjusting the individual
electric power of the group. This is to cater for different requirements and different
thickness of the plastic sheets used. This also helps in situations when there is
different thickness within the same plastic sheet roll.
2. In front of the material feeding section, there is a heat blocking window.
3. On top of furnace is equipped with a compressed air canister, which is used for
manually elevating the furnace during machine maintenance or machine shutdown.
This will prevent the machine or mould from deforming due to the heat.
E. Bottom Plate
5
It major use is to allow the loading of mould and this is where the heated plastic
sheets will be vacuum formed to form the end-product based on the mould’s design.
The plate can lower itself with the help of compressed air system. So after the cooling
process, the plate will lower itself and the hardened sheets after cooling will detach
from the mould.
F.Compressed Air and Vacuum Pump System
20 HP compressor combined with dryer to operate machine with air rectification
system.
(1) Vacuum System: Using vacuum pump to create suction in the bottom mould plate
to generate vacuum forming.
G. Cooling Water Spraying System
Is made up of few groups: (1) Cold water maker (2) Cold water pump (3) Mist maker
(4) Air blower, etc.
(1) Cold Water Maker, works in repeating motion in the following manner:
Compressor  Air conditioner  Storage tank  Filter and heat removal 
High pressure meter (15-18kg/cm2)
Thermometer
pressure reduction  mist maker / cold water  back to compressor
Low pressure meter (3-4kg/cm2)
(2) Cold water pump is using 370W electricity. Water pump sends the cold water to
the mist maker, which will start cooling process by spraying cold mist onto the hot
plastic sheet which has completed the vacuum forming cycle.
(3) Blowing and water spraying will also occur at the same time to further cool and
harden the plastic sheets which ahs already been moulded. Blower will act as dryer
and therefore water spraying time should always be shorter than that of blowing time.
H. Final Cutting / Separation
(1) Rear container’s main usage is to collect the cut final product, which should be
periodically be removed away from the machine once it has reached a reasonable
quantity, in order not to interfere with the normal operation. Rear container’s position
can be adjusted accordingly.
(2) Cutting knife and press blades working simultaneously in cutting process.
(3) Compressor will operate the movement and cutting on the cutting knife.
(4) Supporting tray to lift up for balancing & protect plastic sheet in good condition
during cutting process, & down to release plastic sheet in progressive movemement.
6
(5) Furnace control is made up of 27 groups of electric current meter (1 meter
controlling 2 heating tiles) and 27 controllers. It can also be 54 electrical current
meter with 54 controllers. (1 meter controlling 1 heating tile)
4. MACHINE’S ELECTRICAL SYSTEM
1. Our machine uses xxxxxx 380V 50hz electricity
2. Machine will need to install a 60A xxxxxxx
5. MACHINE DELIVERY AND INSTALLATION
1. Delivery through vertical suspension
When suspending the machine during delivery, please ensure centre of gravity of the
machine is rightly captured to prevent the machine from toppling over. The medium
used to suspend the machine must be strong enough to withstand the weight, and
various important parts of the machine must be fastened (see diagram provided).
Ensure stability when lowering the suspending machine on to the ground and all
corners of the machine should be protected to prevent knocks and scratches.
2. Installation of machine
(1) Machine installation tolerance is 1000: 0.5mm
(2) If more than 1 machine is to be installed, proper planning has to be done with
regards to ease of movement, facing directions of the machine and ample empty space
for operation.
6. MACHINE TUNING, OPERATING AND LUBRICATING
1. Before tuning and operating this machine, operator must be familiar with the main
structures, capability and proper usage of the machine. It is advised to read the user
manual of the machine to understand the operating rationale and logic, as well as
safety measures before using the machine.
2. Operator has to make the following preparation before embarking on the tuning and
operation of the machine. (only to be carried out after the proper assembling and
installation of the whole machine)
(1) Many of the machine components make use of compressed air to be the source of
energy and movement and therefore the machine requires the use of an air
compressor. The requirement of air compressor must process air volume intake of
2m3 / min, output air pressure if 6-8kg/cm2. 15K. Air compressor is sold separately
and must be tightly attached to the air socket head of the machine.
(2) Even for trial run after the necessary tunings, there is a need to ensure proper
materials are used and product mould tightly attached onto the bottom mould plate.
(product mould is not provided and is to be ordered separately based on the
customer’s requirement)
(3) Cool water container must be attached to clean tap water.
7
(4) Repeatedly and thoroughly check the whole machine (not less than twice) to
identify if there are any incorrect/improper installations of the machine parts, and
whether there are any defects caused by knocks during delivery or during the
assembling of the machine. Oversights such as screws not tighten and missing parts
should be rectified immediately before starting the machine.
(5) Based on requirement, sufficient rows of plastic sheets of correct width and
thickness should be ready before production. Feeding stand and guiding chains should
be adjusted accordingly based on the material’s specifications.
(6) Based on requirement of the forming length and width, the number of heaters to be
powered on and their temperature should be properly adjusted first. The length of
material feeding should also be properly set.
(7) Tighten the dual needle chains to the desired tension by adjusting on the wheel.
(8) All timers, eg. Cooling timer, cutting timer, etc should be properly set based on
the material specification.
After doing the necessary preparations as stated above, you can proceed on with the
testing / trial run. The testing should be done individually on each machine
component.
7. SAFETY MEASURE AND MAINTENANCE
How to use the machine safely
1. Only trained personnel, who must be familiar with the functions of the machine and
operate it safely, must operate on the machine.
2. To ensure the safety of the operator and the maintenance crew, and the well-being
of the machine, here are some of the things to do:
(1) Any adjustments to the machine components eg. Number of heaters to be
powered, the length of material feeding, tension of the dual needle chains, etc. must
be done only after the complete stop of the machine. In addition, there must be checks
to make sure that everything are properly fastened.
(2) All far infra-red ceramic heaters must be totally cooled down before doing the
necessary adjustments. This is to prevent serious burnt.
(3) While adjusting the width of the guiding ramp or when using wider plastic sheets,
care must be taken to ensure the sheets and the ramp are 90-degrees against each
other.
(4) If there are any abnormal sounds or burning smells during operation, the machine
must be stopped immediately and thorough checks must be carried out. The machine
can only be switched on after understanding and rectifying the cause of the problem.
(5) Whenever there are any needs for machine checking or maintenance in the middle
of operation, the furnace must be in the elevated position. This is to prevent the
8
burning and deforming of the vacuum forming machine and its components and thus
affecting its functionality.
8. MACHINE MAINTENANCE
1. Beside regular application of lubricant at designated places, the cooling blower /
fan, wheels etc must be re-oiled at least once annually.
2. The cooling system and its components must be cleaned of debris periodically
every year so as not to reduce its cooling effect.
3. Cooling water container must be cleaned with washing powder periodically to
ensure the cooling capacities. Cooling water container must be using clean tap water
for operation and periodically washed to prevent the blockage of the sprayer heads.
4. There must be periodic checks on vacuum pumps and all piping joints. This is to
prevent air leakage. If the cooling speed is not up to requirement, checks must be
done on the cooling pipes to find if there are any leakages, If there are leakages,
welding must be done on the problem areas immediately and refill the cooling
solutions in order to reach the pressure requirements (lowest pressure point 35kg/cm2 , highest pressure point 14-18 kg/cm2). (How to check: spread soap water or
washing powder water at the suspected areas, and examine when air is running
through the pipes.)
