Plastic Formwork systems

 What is Plastic Formwork System for

Concrete Casting   

Plastic formwork system is new kind of modular formwork system which recently take attraction in construction industry. Due to light weight and fast locking design handles can be carried out easily by single person. The weight of each square meter of plastic formwork is around 14 kg in comparison to 45 kg for traditional steel formwork . With this in mind, safety is top priorities in construction project so because of its easy to handle, the accident id worksite will goes down to have safer sites for our workforce

Zagros Plastic Formworks (ZAGPLAST) and shuttering stuffs are made up of high quality ABS or PP (PolyPropylene) with flexural-enhanced material. Our construction plastic formwork has been designed to create smooth and exposed concrete surface for finished layer. Hence aesthetically pleasing surface would be  expected by using plastic formwrok system. Non-stick feature of polymer which turns to not adhere concrete to them is main reason for last-long and durability of plastic formwork

 when it comes to types of material for plastic injection for producing plastic Panels formwork, we have two options : 

• Raw Material such as ABS, PolyPropylene (PP) and Poly Ethylene (PE)
• Recycled Material (black recycled PP)

Plywood or Metal Formwork could be replaced completely with Plastic Panels and plastic panels are eco-friendly and environmental friendly choice. The expectation is to use them more than 100 times and then can be recycled plastic panels and produce the recycled ones. 

Advantages of Plastic Formwork System: 

•  Light weight, Rigid, Strong, Durable, Waterproof, Moisture-proof 
• Chemical resistace, Anti-impact and fade, Anti-folding, Anti-Aging, High flexural strength properties
• Easy to fabricate, Custom size, Non-toxic
• Corrosion-resistanct, Finished sufrace of concrete wall, columns or slab will be gorgeous, rich in quality, Odorless
• Environmental friendly. Recyclable, Washable with water, 

Let's start with Size of Plastic Panels we provide and also prices of each panels:

As you know in construction sector and all types of industry, the first and foremost factor for doer and contractors is Price.  

 To comparison plastic formwork system with traditional formwork and metal (Steel) formwork, we provide a table for detailed comparison :

 Types of plastic Formwork: 

Concrete plastic formwork are produced and supplied in two general types and shapes:

The first one is 5 cm thickness Concrete plastic formwork (similar to 5 cm edge Concrete steel formwork)

This type of concrete plastic formwork has the ability to be compatible and paired with the concrete steel formwork, and therefore this type of concrete plastic formwork can be easily paired with the concrete steel formwork. The tools for closing the concrete plastic formwork with a 5 cm edge are the same pins and wedges used in the concrete steel formwork. These plastic formworks is now available in three sizes

100x50 cm

100x40 cm

100x35 cm

100x30 cm

100x25 cm

100x20 cm

100x15 cm

100x20 cm

The second one is concrete plastic formwork with an thickness of 8 cm, which is known as the Italian concrete plastic formwork.

The weight of each square meter of concrete plastic formwork is around 14 kg, which is much lighter compared to the weight of 45 kg per square meter of concrete steel formwork. It is obvious that the lighter the weight of the concrete plastic formwork, the higher the execution speed and the safety and fatigue of the workforce is reduced.

On the other hand, due to the low weight of these molds, it is possible to load 300 square meters of these molds in a 5.5-meter truck. Concrete plastic formwork are produced in different dimensions other than concrete steel formwork. The height of concrete plastic formwork is 60 cm and they are designed and produced in different lengths from 20 cm to 120 cm.

Sizes of concrete plastic formwork

Modular concrete plastic formwork are produced and supplied in different dimensions.

concrete plastic formwork 120x60 cm: This plastic mold is called (BP120) which has a length of 120 cm and a height of 60 cm.

concrete plastic formwork 20x60 cm: This plastic mold is called (BP20) which has a length of 20 cm and a height of 60 cm.

concrete plastic formwork 25x60 cm: This plastic mold is called (BP25) which has a length of 25 cm and a height of 60 cm.

concrete plastic formwork 30x60 cm: This plastic mold is called (BP30) which has a length of 30 cm and a height of 60 cm.

concrete plastic formwork 35x60 cm: This plastic mold is called (BP35) which has a length of 35 cm and a height of 60 cm.

concrete plastic formwork 40x60 cm: This plastic mold is called (BP40) which has a length of 40 cm and a height of 60 cm.

Inner corner concrete plastic formwork: This plastic mold is called (BPIN) which has a length of 30 cm and a height of 60 cm.

External corner concrete plastic formwork: This plastic mold is called (BPOUT) which has a length of 25 cm and a height of 60 cm.

Again, to the dear readers of this article, I would like to say that all the concrete plastic formwork produced by Baspar Sanat Beton Company have a height of 60 cm, and when it comes to the BP20 mold, for example, the number 20 represents the length of that mold, that is, 20 cm. The height of this mold is 60 cm.

Special Plastic Columns Formwork System:

The column concrete plastic formwork produced in Baspar Concrete Company are considered to be an interesting and attractive light source in this field. concrete plastic formwork columns are produced in two sizes:

1- Column concrete plastic formwork 60x60 cm: This column format is called BPS2060, which has a length of 60 cm and a height of 60 cm. Price of concrete plastic formwork is around $50/sqm for ABS material and for PP material is around $20/sqm. By purchasing a set of Column formwork that includes 20 column molds with 150 levers. With these 20 plastic column molds, all column dimensions from 20x20 cm to 60x60 cm can be concreted. The point to be mentioned in this case is the weight of this plastic column, the whole molds and accessories of this column weigh about 145 kg, which is not comparable to a metal column of the same size. Therefore, in villa construction projects where the use of a crane is a challenge, it is a very suitable option for the implementation of foundation, wall and slab roof.

Due to the ability of concrete plastic columns formwork to be adjusted, there is no need to use zero corners, 10 and 5 cm corners. For example, if the employer needs to cover a 60x50 cm column using plastic column molds, it is enough to put one side or one side of the column panels on the 60 cm number and the other side and the other side on the plastic mold. Set it to 50 cm, and then the desired column will be formatted.

From the right side, the first mold, which is a plastic column mold, which, as mentioned above, has a height of 60 cm, due to the ability of the column molds to be rigged, one rib has been deducted on the 60 cm column molds and the molds on the part 50 cm of the column is closed and the desired plastic column is ready for concreting.

Maybe this question will arise, how will the scaffolding of concrete plastic formwork have to be done?

The simplest answer to this question is that the restraint of these concrete plastic formwork is just like steel plastic formwork and you can use the same double-tube or single-tube gasket with conventional scaffolding pipes or solders made of 40x80 mm cans.

2- Column Plastic Formwork panel 65x60 cm: This column format is called BPS2565, which has a length of 65 cm and a height of 60 cm.

Baspar concrete company has put the exclusive production of these concrete plastic formwork on its agenda since 2008, and the concrete plastic formwork of this company are known under the brand name Baspar Panel (Baspar Panel) in the market of Iran and the Middle East.

The main feature of Beton Baspar concrete plastic formwork is the edge thickness of these molds, which is 8 cm. The concrete steel formwork available in the Iranian market have 5 cm edges. Since the elastic modulus of metal is about 200 GP (GigaPasgal), which is much higher compared to ABS polymer, the edge of plastic molds should be 8 cm to compensate for this defect of plastic compared to metal.

Recently, in the Iranian market, a 5 cm thickness concrete plastic formwork made of polyethylene has been produced and entered the market. Due to the lack of stiffness with the issues related to the very low modulus of elasticity of polyethylene compared to iron, it has not been able to satisfy the customers need and lead to the pessimism views towards plastic formwork system and polymer formworks.

What is the raw material of concrete plastic molds or polymer molds?

When the production of polymer or plastic molds is on the agenda, three types of petrochemical raw materials can be used:

Acrylonitrile butadiene styrene polymer (ABS)

Polypropylene polymer (PP)

Polyethylene polymer (PE)

With a brief search and examination of the characteristics of the above three polymers, it is easy to see that the mechanical characteristics of the ABS polymer are much higher and stronger compared to the other two polymers. Therefore, Beton Baspar Sanat produces polymer molds in two types and characteristics, one with ABS polymer and the other with PP polymer. The price of plastic molds produced with PP polypropylene polymer is almost half the price of ABS polymer molds.

What is the main advantage of plastic molds over metal molds?

Light weight and ease of implementation and installation due to the weight of one third of these molds compared to metal molds

Due to the light weight, the transportation of plastic molds is faster and easier

Due to the insulating nature of plastic, pegplastic molds can be used in different temperature conditions

No need for lubrication is one of the advantages of plastic molds

Washing plastic molds with water jet easily makes it possible to increase the useful life of the molds many times

ABS plastic molds can be used 100 times and the waste of these molds has 40% of the selling price.

Considering the waste recycling of these molds, it can be noted that polymer and plastic molds are environmentally friendly.

We produce, from 20 years ago, all type of concrete plastic formwork systems in Walls, adjustable columns and slab as well. When you visit our website. You’ll find two options in concrete plastic formwork systems: panels with body thickness of 8 cm or 5 cm. each panels has its own application and if you need inquiries or piece of information about them, don’t hesitate to contact us via Email, Whatsapp, Telegram or even call.

If your work area is in the remote place, your definitely have no access to crane, and better to reconsider your choice from steel formwork system to plastic formwork systems.

What are the advantages of plastic formwork for concrete?

Due to the perfect production process and use of high quality injection machine, the surface of plastic formworks is like polished and therefore the final surface of your concrete will be exposed without any kinds of spots.

Due to precise injection mold design, the leakage of concrete (ordinary density around 2400 kg/m3) and foam concrete (less than 800 kg/m3 in density) is avoided and you could easily use them for tunnel structural system.

Due to light weight of panels which hardly reach to 13 kg per square meter, it is the most efficient labor-saving system because it is easily and fast in install and move in project sites. In comparison to steel formwork system that has 40 kg per square meter in weight, installation agility and process decreased drastically. 

Due to raw material, it is easy recycled and it is evidence for being environmental friendly formwork. Just compare the wood formwork which would have burned at the end of project and the result is deforestation.

Due to polymer-made formwork, evaporation of concrete’s water will be avoided, especially in some countries like Gulf area (KSA, UAE, Oman, Qatar, …) and also in frozen climate this formwork acts as insolation system and keep away the core of concrete from freezing.
