LAMINATION PROCESS

Lamination Process

A process in which aim to consolidate the bar eliminating internal pores and reduce gaps along the margin area the chip

Packing Preparation → Vacuum Packing → Lamination → Heat Treatment → Vinyly Unpacking

What are the sub-process of lamination process

Packing Preparation

Process of arranging the bars into its corresponding recipe

Paper
PET rubber
PET Film

Base Film
SUS Plate
Aluminum Plate

Viynl Bag

7 Material under packing preparation

Vacuum Packing

A process of removing air inside the bar negative pressure the sealing the viynl

Vacuum Packing

A process of de-airing the present between layers in margin area

Lamination

A process that transform the multi-layer stacked bar into “monolithic bar”

Lamination Temperature

Lamination Pressure

Lamination Keetime

What are the 3 quality item of lamination

Pascal Principle

A principle that lamination sub process uses in which is use pressure and is apply to any part of the given margin area of the bar

Circulating Pump
Air Operated Valve
High and Low pressure pump

3 Primary Lamination Process

Air Operated Valve

system process that manage the hold and release the pressure during lamination pressing

Bar Deformation

Crack and Delam

2 Type of defect under lamination process

Bar Deformation

A type of defect wherein during the pressure increase and compression stages deformation defect may occur due to density inconsistencies

Crack and Delam

A type of defect cause by structural inconsistencies

Heat Treatment

A Process that result to a spring back effect in the bar

Heat Treatment

A Process that improve the sheet to sheet tackiness

120 - 170 C up to 2-3 hours

How much heat and how long does heat treatment uses

Vinyl Unpacking

A process where the packing material within the margin bar

5 Bars

How many units does lamination process uses for quality trial and inspection
