What is vacuum forming? Why would you want to use a vacuum former to make parts for your business or product line? You probably don’t know the answer to these questions, especially if you stumbled upon this article by accident. In just 5 minutes you’ll have learned what a vacuum former does, and why it is useful?
Vacuum Forming Machine:
A vacuum forming machine is a very handy device that can be used for a huge variety of applications. It is used for molding plastic sheets into shapes that are not easily achievable by other methods. The plastic sheets are heated to the required temperature and then sucked over a mold using vacuum pressure.
The machine has two main sections: the first is the oven that heats up the plastic sheet and the other section houses the vacuum system that shapes it into place. In between these two sections is a mold, which is where the magic happens.
The vacuum forming process starts with placing a piece of the plastic sheet onto a mold. The mold is placed in a sealed box called the “platen.” A vacuum is applied to the platen, which causes the plastic sheet to be sucked down over the mold. The material tightens and stretches as it conforms to the shape of the mold.
Once it has cooled, the vacuum is released and the part is removed from the mold.
One of the main advantages of this process is that it can be done quickly and at a low cost, making it ideal for prototyping and one-off parts.
Conclusion:
Vacuum forming is one of the oldest and most cost-effective methods to form plastic sheets. It is a process that uses heat and vacuum to create parts out of plastic sheets. All in all, vacuum forming is more cost-effective and provides a rapid prototyping process compared to its counterparts.
Generally, it has three shapes: rectangle, square and circle. For bedrooms and study, it is more appropriate for us to choose circular ceiling lamps, while for living rooms and restaurants, square ceiling lamps will appear more spacious, while kitchens and bathrooms are generally square shapes similar to integrated ceiling.
Now, from the material of its outer lampshade, there are about three kinds of lampshade materials: acrylic, plastic and glass. For the quality of acrylic lampshade, we can judge it by hand touch to see how soft it is. Softer ones are better; Then put the palm of your hand to see the color. It’s ruddy; Open the cover to see if it is convenient to disassemble.
Secondly, let’s take a look at its light source. Generally speaking, its light source can be divided into ordinary incandescent lamp, fluorescent lamp, tungsten halogen lamp and LED lamp. Of course, different light sources are suitable for different places. If it is for household use, ceiling lamps can be preferred. The ceiling lamp of LED light source is not very expensive, but it saves electricity, has a long service life, strong brightness and high cost performance.
In addition, its size should also be determined according to the size of the bedroom area. If you choose too small ceiling lamp, it will appear that the top space of the room is spacious. Of course, we can’t use too large ceiling lamp, otherwise it will be noisy and dominate.
The general size of the square ceiling lamp and how to buy the square ceiling lamp in the bedroom are introduced here. In general, to choose the appropriate products, we mainly depend on the actual needs. In addition, when choosing, we must go to the brand store, so as to ensure the quality.
Installation precautions 1. Ceiling lamps cannot be directly installed on combustible objects. In order to be beautiful, some families use three plywood with paint surface to lining the back of ceiling lamps. In fact, this is very dangerous, and thermal insulation measures must be taken. If the high-temperature part on the surface of lamps is close to combustibles, thermal insulation or heat dissipation measures should also be taken.
Installation precautions 2. Wrap the connecting wire well. For the use safety of lamps, the electrical contact between the two wire ends connected with the incoming line of ceiling lamp power supply should be good, and they should be wrapped with black tape respectively, and a certain distance should be maintained. If possible, try not to put the two wire ends under the same metal sheet to avoid short circuit and danger.
Installation precautions 3. The ceiling lamp shall also be checked before installation. Generally, it needs to be checked in detail before the installation of the ceiling lamp, mainly to check the section of the conductor core leading to each lamp. The copper core flexible wire shall not be less than 0.75mm, otherwise the lead must be replaced; The connection between wires and lamp caps and the connection of parallel wires between lamp caps shall be firm, and the electrical contact shall be good, so as to avoid danger caused by sparks between wires and terminals due to poor contact.
The area of children’s bedroom is 20 square meters, and the corresponding use area of ceiling lamp is 15-25 square meters, which is in the middle. The whole body is divided into two parts, one is the lampshade and the other is the chassis.
Product details
The diameter of ceiling lamp is 46cm, the thickness is 7.2cm and the power is 48W. As the main lighting lamp in children’s room, its use will be reflected incisively and vividly. Through the appearance, we can see that the overall design is a modern and simple design style. The lampshade presents a spherical shape, and the material adopts an optical acrylic mask. Combined with professional optical ratio, it is very light, but very solid, not easy to oxidize, and will not fade and turn yellow after long-term use; Therefore, the mask can ensure the optical performance and high transmittance, make the beam uniform, comfortable and soft, and ensure the user’s recognition of the product. Compared with non fragile plastics, PVC, recyclable acrylic and PS ordinary plastics, they are excellent in hardness, firmness and light texture.
At present, the floor height of the room is only between 2.6m and 2.75m. Therefore, in order to achieve better use effect, the overall space height will not be reduced due to the thickness of ceiling lamp. After study and judgment, the overall thickness of the ceiling lamp is adjusted to 7.2cm, with ultra-thin narrow edge and 20mm frame, which effectively raises the floor height by 20mm and retains more space. At the same time, OPP intelligent ceiling lamp adopts double-sided light transmission technology, which breaks the dark side of ordinary ceiling lamp with one side bright and one side with back halo, that is to peel off the glare caused by dark top contrast, and expand the light transmission range to 360 °, so it can illuminate the brightness of the whole room more comprehensively.
The intelligent ceiling lamp bead adopts OPP high-efficiency LED lamp bead, which has higher brightness, longer service life, more energy-saving and more durable. Because the power of this product is 48W, and there are just 48 lamp beads, it can be judged that a lamp bead is 1W. The design structure is divided into four directions: East, West, North and south, with a total of 2 circles inside and outside. There are 8 light beads in each direction of the inner ring, with a total of 4 directions; One direction of the periphery is 4 light beads, a total of 4 directions. The LED light beads are effectively arranged to make the light irradiation more uniform.
The intelligent ceiling lamp LED control device is located in the middle of the whole chassis. It is fixed on the chassis after delivery. There are no special circumstances. You can ignore it here and don’t move it. Just connect the zero line and the live line. In other words, when it comes to installation, there are not too many cumbersome things to do during installation. It is very simple.
The intelligent ceiling lamp adopts industrial grade all aluminum frame, which is integrally formed, with high strength, good toughness, stability and durability. It adopts the spraying fine powder process, which is anti-oxidation, non rusting, delicate and exquisite, glowing with texture and luster. The company logo can be printed on the surface of the lampshade.
The intelligent ceiling lamp adopts a sealed design structure. Here is a personal experience, that is, the ceiling lamp before replacing the intelligent ceiling lamp. After using it for a period of time, there are always black mosquitoes or moths in the middle of the lampshade. Every time you turn on the ceiling lamp, it is densely listed in it, which makes you feel unfamiliar. The smart ceiling lamp adopts a flat appearance design, discards the groove design, and adopts a close fitting design inside, adding a protective sealing rubber ring, which can effectively avoid the repetition of the above-mentioned personal experience and ensure that the light of the LED and the overall lampshade will not decay.

Plastics exist in various shapes, colors, and types. These different types of plastics are distinct from each other and have different uses. To make informed decisions when buying plastics and plastic products, you need to understand the types that exist. Let’s get you informed on the different types of plastics there are.
The knowledge for the material used for vacuum forming:
ABS:Acrylonitrile Butadiene Styrene
PETG:Polyester Copolymer
PS:Polystyrene
PC:Polycarbonate
PP:Polypropylene
PE:Polyethylene
PVC:Polyvinyl Chloride
PMMA:Acrylic
HIPS:High Impact Polystyrene
Polyethylene Terephthalate (PET)
PET is a lightweight and often transparent plastic. It’s commonly used for making packaging containers such as water bottles. PET is one of the safer plastics, hence its use in food packaging. The plastic is, however, unsafe for use in preserving hot food. PET is easily recycled.
Polyethylene
Polyethylene is the second most common plastic in the globe. Polyethylene is classified into three categories: high density, low density, and linear low-density, based on the varying strengths of the plastic.
High-Density Polyethylene (HDPE)
HDPE is the strongest and most resistant of the three Polyethylene. HDPE’s high resistance makes it ideal in making cartons, containers, and pipes, among other products.
Linear Low-Density Polyethylene (LLDPE)
A slight tweak of chemical processes in the manufacture of polyethylene yields LLDPE. LLDPE is commonly used for making plastic bags, which are common in grocery stores. Like all polyethylenes, LLDPE holds up quite well against chemicals and is tear-resistant.
Low-Density Polyethylene (LDPE)
Compared to HDPE and LLDPE, LDPE has the simplest polymer structure. LDPE is a softer and much clearer version of Polyethylene. The plastic is used as a liner in food packaging cartons, dispensing bottles, and plastic wraps.
Polyvinyl Chloride (PVC or Vinyl)
PVC is a rigid plastic that is resistant to weathering and chemicals and is, therefore, most preferred for building and construction purposes. PVC has some versatile properties: durability, lightness, rigidity, and processability. Due to its versatility, PVC is slowly replacing traditional building materials like metal, wood, and concrete.
As an incredibly strong material that doesn’t conduct electricity, PVC is well utilized in high-tech applications. Common high-tech applications of PVC include wire and cable production and medical equipment production.
Polypropylene (PP)
Polypropylene is rigid, sturdy, and resistant to heat. PP’s strength is somewhere between LDPE’s and HDPE’s strengths. This plastic is used in making hot food containers, thermal vests, Tupperware, car parts, and disposable diapers. PP is resistant to heat, making it ideal for holding hot items or being heated itself. PP is also resistant to fatigue and therefore preferred for use as living hinges.
PP is the safest of all plastics since it is heat resistant and cannot leach toxic chemicals even when exposed to high temperatures, unlike most other plastics.
Polystyrene (PS)
Polystyrene, commercially known as Styrofoam, exists in either solid form or foamed. This plastic is used to make beverage cups, egg cartons, dinnerware, and packaging materials. Styrofoam is cheap and insulates very well, which is why it’s preferred for food packaging.
However, PS is considered one of the worst types of plastics for the following reasons:
• It is non-biodegradable.
• It has low specific gravity and is easily blown by the wind and floats on water.
• It is harmful to humans. When exposed to heat, it could leach styrene, which is a nervous system and brain toxicant.
• It has a low recycling rate.
The use of PS is being discouraged due to the multiple risks it poses.
Other plastic types like polycarbonates (PC) can’t fit in any of the discussed types. Polycarbonates are solid and rigid products used for making sunglasses, compact discs, and safety goggles.
Understanding the different types of plastics helps you decide which ones would best fit your needs. This blog has briefly highlighted the most common plastic types to help you make an informed decision. For more information, please contact us.
