Twin Screw Extrusion

Twin Screw Extrusion is used comprehensively for mixing, compounding, or reacting polymeric materials. The suppleness of twin screw extrusion equipment allows this operation to be designed specifically for the formulation being processed. For example, the two screws may be correlating or counter rotating, intermeshing or no intermeshing.such as single screw extruders for blown film sheet extrusion, Coumpounding extruders and recycling extruders, twin screw Extruders, and rubber extruders to meet all the clients 

In addition, the configurations of the screws themselves may be varied using forward conveying elements,  kneading blocks, and other designs in order to achieve particular mixing characteristics.

Bimetallic Screw & Barrels

Type                           Extrusion, Injection Moulding  and Compounding
Configuration             Single Bore, Parallel & Conical Twin Bore

Manufacture

Nitrided and Bimetallic for single and parallel twin bore barrels. Nitrided only for conical twin barrels. The Bimetallic specification depending on grade selected can give as much as 4/5 times greater life than the nitrided barrel. When the bimetallic barrel has worn to the point where the wear is effecting performance, it can be re-lined with new liners. This re-lining can be done many times.

Size Range                     38mm – 250mm bore diameter
Maximum Length            7 metres

KAIVANYA EXTRUSION TECHNIK  Company , is a work team of manufacture, sales & professional design plastic machinery screw & barrel. Injection Molding is a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials.

Material is fed into a heated barrel, mixed, and forced into a mold cavity where it cools and hardens to the configuration of the mold cavity.

Injection Molding is widely used for manufacturing a variety of parts, from the smallest component to entire body panels of cars.

Applications:

• Injection Molding is used to create many things such as wire spools, packaging, bottle caps, automotive dashboards, pocket combs, and most other plastic products which are available today in market.
• Injection molding is the most common method of part manufacturing. It is ideal for producing high volumes of the same object.

Advantages

Injection Molding are high production rates, repeatable high tolerances, the ability to use a wide range of materials, low labor cost, minimal scrap losses, and little need to finish parts after molding.

Disadvantages
Injection Molding are expensive equipment investment, potentially high running costs, and the need to design moldable parts.

Process of Injection Molding

• With Injection Molding, granular plastic is fed by gravity from a hopper into a heated barrel.
• As the granules are slowly moved forward by a screw-type plunger, the plastic is forced into a heated chamber, where it is melted. 
• As the plunger advances, the melted plastic is forced through a nozzle that rests against the mold, allowing it to enter the mold cavity through a gate and runner system.
  The mold remains cold so the plastic solidifies almost as soon as the mold is filled.
