Cooling Chamber Water Connection Ports... - Page 9 Atlas™ Constant Thickness Film Maker The cooling chamber (1) has water inlet/outlet ports (4) at the rear of the unit and the black silicone tubing supplied with the Atlas™ Heated Platens simply pushes on to these ribbed hose type connections. (See Fig 1.) For additional safety, cable ties can be placed around the tubing and hose connections to prevent the tubing from becoming disconnected if the cooling water supply pressure is high.

5. Operation of the Film Maker Accessory Follow the instructions from the user manual of the Atlas™ Heated Platens P/N GS15515 for their installation and operation in a Specac Press prior to use of the P/N GS15640 Atlas™ Constant Thickness Film Maker Accessory. - Page 11 Atlas™ Constant Thickness Film Maker Fig 2. Top and Lower Platen Pressing Assemblies To make a particular thickness of film sample at 29mm diameter, select the required thickness spacer ring (7) from the six sizes available. The spacer rings are labeled on the outer circumference edge of the ring with an engraved letter from A to F and the letter corresponds to the following nominal thickness of film that can be formed.
- Page 12 User Manual Fig 3. Spacer Ring Fitted to Lower Platen Pressing Assembly With the spacer ring (7) in position, take the guide ring (8) and place this around the spacer ring (7). The smaller inner diameter edge of the guide ring (8) contacts with the outer diameter of the spacer ring (7). (See Fig 4.) Fig 4.

Atlas™ Constant Thickness Film Maker The Aluminium Foil Discs The 40mm diameter aluminium foil discs (9) are used to “sandwich” a sample between them, before melting and pressing of the sample in the Film Maker Accessory of parts. The spacer rings (7) have been specifically designed to accommodate two aluminium foil disc (9) thicknesses. - Page 14 User Manual Take the sample to be melted and pressed and place it in the centre of the lower foil disc (9). The amount of sample to use will vary depending on the thickness of spacer ring (7) chosen. Sample Fig 6.
- Page 15 Atlas™ Constant Thickness Film Maker Note: Some preliminary “test pressings” may need to be carried out when experimenting with new and differing amounts of sample to determine the optimum amount of the sample needed when pressing with a specific sized spacer ring for a nominal film thickness .When the correct amount of sample to be pressed is known, this helps in the production process for the reproducibility of a thin film.

Page 18: Heating The Sample
User Manual Heating the Sample Select a known melting or a “test” set temperature on the controller of the Atlas™ Heated Platens. When the set temperature has been input and accepted, the temperature controller will power the Atlas™ Heated Platens to reach this temperature. Wait for the softening or melt point to be reached. - Page 19 Atlas™ Constant Thickness Film Maker When the actual temperature of the heated platen surfaces (20) and (21) have cooled to about 100ºC below the melting and pressing temperature, release any tonnage load that is being applied and very carefully remove the Film Maker Accessory assembly components from the Press to place in the cooling chamber (1).

Page 20: Accessing The Films
User Manual Hint: Whilst the Film Maker Accessory assembly components are cooling down in the cooling chamber (1), if a second Film Maker Accessory is available, this can already be prepared with a new sample ready for melting and pressing between the Atlas™ Heated Platens. -
