INSERT OVER-MOLDING

OF COATED GLASS

A patented system by PENTACON


Insert over-molding of coated glass

• new and patented system by PENTACON

• high pressure

• technology requires high precision in form making and injection molding


What is the new approach?

• insert over-molding of glass surfaces is not new in the plastics industry

• the over-molding of coated glass has not been possible yet

• high pressure and high temperatures ususally lead to cracks and fractures in

the glass blank


Procedure

The glass blank is inserted and

fixed into the form.

The glass edge is sealed under

high pressure inside of the

form.

The plastic is injectied into the

form.


Advantages

• this new approach will enhance the possible options to use glass

• assembly of complex units not neccessary since the finale part is produced

in a single step

• additional cost reduction while using alternatives and cheaper materials


Advantages

• glass edge is protected and already the over-molded plastic edge may

feature various elements (threads, snappers, etc.)

• glass planes may be connected and sealed simultaneously with additional

plastic parts

• procedure may be used with all common types of plastic including high-tech

materials


Cost savings shown with a common photo filter

common photo filters consist of a rim, glass and an internal rim

1. rim is turned with inner and outer threads and made of

Aluminum or brass

2. rim is hardend

3. internal rim with outer thread made of Aluminum or brass

4. internal rim is hardend

5. glass is inserted

6. all three components are assembled into one unit


Cost savings shown with a common photo filter

new approach

• form,

• internal thread,

• outer thread,

• surface and

• glass

are produced in a single step


Additional scopes of field

• medical technology (tubes, etc.)

• sight glasses

• technical glasses

• optical filters

• displays, touch panels, pressure gauges


Technical parameters

• currently we process glass with

– 10 x 10 mm up to 250 x 250 mm

– thickness from 1 to 10 mm

– compensation of the thickness tolerance ± 0,20 mm

• the glass blank is put under pressure of 1,500 bar and 400° C
