Product types we produce:
Blow molding :
Blow molding ( ⦁ BrE moulding ) is a manufacturing process by which hollow ⦁ plastic parts are formed. In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and injection stretch blow molding. The blow molding process begins with melting down the plastic and forming it into a ⦁ parison or in the case of injection and injection stretch blow moulding (ISB) a preform. The parison is a tube-like piece of plastic with a hole in one end through which compressed air can pass.
The parison is then clamped into a mold and air is blown into it. The air pressure then pushes the plastic out to match the mold. Once the plastic has cooled and hardened the mold opens up and the part is ejected.
Blow P.E.T. Molding :
Blow molding machine uses double stage production process. The first step is preform production with the use of injection machines. The final form (bottle) is made during the stretch blow molding process employing one of PP or PET blowing machines. It is the second stage of the whole production process.
BOTTLE PRODUCTION PROCESS (SECOND STEP)
1 Preform heating in a special preform heater.
2 Opening of the blow mould (by closing unit) and insertion of the preform.
3 Closing of the blow mould.
4 Bottle stretching and blowing.
5 Opening of the mould and transport of the finished bottle to the exit conveyor.
6 Bottle prepared to transport.
Injection Polypropylene :
Melt processing of polypropylene can be achieved via ⦁ extrusion and ⦁ molding. Common extrusion methods include production of melt-blown and spun-bond fibers to form long rolls for future conversion into a wide range of useful products, such as face masks, filters, diapers and wipes.
The most common shaping technique is injection molding, which is used for parts such as cups, cutlery, vials, caps, containers, housewares, and automotive parts such as batteries. The related techniques of blow molding and injection-stretch blow molding are also used, which involve both extrusion and molding.
The large number of end-use applications for polypropylene are often possible because of the ability to tailor grades with specific molecular properties and additives during its manufacture. For example, antistatic additives can be added to help polypropylene surfaces resist dust and dirt. Many physical finishing techniques can also be used on polypropylene, such as machining. Surface treatments can be applied to polypropylene parts in order to promote adhesion of printing ink and paints.
Injection Polyethylene :
In general polyethylene is light in weight and possess strength, chemical resistance, impermeability and impressive electrical insulating properties. Furthermore, the economical cost of the material makes it an excellent material for disposable and recyclable industrial product applications, whilst it’s comparative low density enables more volume of plastic to be processed.
Polyethylene is available in many different densities.
⦁ High density polyethylene (HPDE) – a food-grade plastic
⦁ Low density polyethylene (LDPE)
⦁ Linear low density polyethylene (LLDPE)
The higher the density of the polyethylene material used the stronger, more rigid and more heat resistant the plastic is. The higher density models show better properties in tensile strength, chemical and heat resistance, surface hardness and abrasion resistance. HDPE for injection molding works well in both hot and cold temperatures and has a tensile strength of 4550 pounds per inch.
Benefits of Polyethylene
⦁ High levels of ductility
⦁ Tensile strength
⦁ Impact resistance
⦁ Resistance to moisture absorption
Industrial Applications of Polyethylene
The versatility of the polyethylene makes the material an ideal choice for the following industries and products:
⦁ Agricultural products
⦁ Lawn and Garden products
⦁ Heavy construction
⦁ Consumer products, including toys, food containers and garbage receptacles
⦁ Plumbing products
⦁ Medical products
