Hi Guys in this article we learn the new topic Transfer Moulding its Limitations, Advantages and Disadvantages  it is important topic in Machine Tools and Processes, for better understanding point let's start,

Transfer Moulding it's Limitations, Advantages and Disadvantages   

Transfer Moulding it's Limitations, Advantages and Disadvantages 

Working

Transfer moulding is also known as gate moulding. Is modified form of compression moulding. Transfer molding was developed largely to avoiding the disadvantages establish with compression molding. Transfer molding can make intricate accurate parts than possible with compression molding. Transfer moulding permits the use of intricate inserts and slender cores not practicable with the compression molding methods. Transfer molding produce components better quality and at economical in rates.

Transfer Moulding it's Limitations, Advantages and Disadvantages  

 Transfer moulding employed in thick sections. In this method the moulding powder is heated to plastic stage and then forced from a cylinder during relatively opening into the main mould proper when the curing is completed. Thus flow through restricted passage, the moulding powder become heated more rapidly and uniformly by conduction from the walls of the mould. 

The plastic in the powder or pillet from is placed in transfer chamber. Under heat and pressure it is transfer into mould cavity. The curing time required after transfer is just one third of the compression moulding curing time. Once the plastic material has cured, the plunger moves top and plastic component is injected from lower portion of mold cavity with the help of ejector pins. 

Another method is known as Jet Molding brings the transfer method closer to injection molding as used for thermoplastics. The plastic material is forced by ram through a heated jet where it becomes soft before entering the closer die, good flowing materials with a long flow period are desirable.

Advantages of Transfer Moulding

1) This process provide relatively close tolerances and fairly uniform density.

2) Cavities formation within the product due to vaporization of resins is avoided due to high pressure applied.

3) The Operation is easier and enables trouble free  production of intricate parts with this section as mould is not directly subjected to compressive force 

4) Transfer moulding is useful for incorporated metal parts in the moulding.

5) High production rate.

6) Medium tooling cost.

Disadvantages of Transfer Moulding

1) Tooling is expensive due to complex nature.

2) Moulding pressure is high compare to compression moulding.

3) As compared to injection moulding product devotion are not good.

4) In transfer moulding requiring removal of flash.

Limitations of Transfer Moulding

1) The transfer moulds complex.

2) Loss of material as scrap.

3) Cost is high.

So in this article we discussed Transfer Moulding its Limitations, Advantages and Disadvantages hope you this information is useful for you.

Thanks for reading 🙏.
