REPORT
TWO CAVITY
THREE PLATE
MOLUD

6. INTODUCTION
As a part of our curriculum
we the final year students of
Diploma in Tool Engineering and
Digital Manufacturing, need to do
ON JOB TRAINING REPORT on
specific topic by utilizing all the
knowledge gained during the
curriculum and its helps on
validating our DESIGNING
KNOWLEDGE.

7. ACKNOWLEDGEMENT
FIRST WE THANK TO
Our Honorable Principal: Mr. Surendhar
Report Incharge: Mr. Ram prasath

8. DESIGN SELECTION
We the trainees of D3 Section have collected
different types of press tool and Mould
components and finally selected the mould
component design.

9. PROPOSED METHOD
 The Selected Component Required tool for
Double Cavity mould and it used a injection Moulding
Machine.
 The Plastic material (PP) are Feed into the Hopper,
the material transfer from liquid state due to heat
 Inject the molten plastic material in to the mould
 After that, the component get Cool and Solidifies
and ejected the final part.
