Such recipes
define the overall power input as well as the
lamp configuration and other important process
variables consistent with the resin and preform/
bottle design.

Set up conditions
Configuration
- When starting to process a new resin, first
run through new preforms for 15 minutes at
‘standard’ conditions to establish steady state
conditions prior to any process optimization
- Slowly start to reduce preform blowing
temperatures until failures are present
(visible pearl internal wall or pearl feet)
- Increase blowing temperatures until defects
are eliminated
- QC check bottle quality for acceptance versus
established tolerances
- Change the power consumption profile in the
ovens for early heat and longer sink times but
ensure overall temperatures do not exceed cold
crystallization temperature
- Repeat temperature reduction stage and
then defect elimination stage to test if further
optimization is possible
- Recheck QC bottle quality for acceptance versus
established tolerances
- Log all process parameters and create new
specific ‘recipe’ for future use

ATO is only used as an industrial intermediate in manufacturing locations
designed for the handling of plastics and chemicals.
However, it can react with other materials in the soil and water to form other
compounds.
Environment
When used in an industrial setting, ATO is typically handled using engineered systems
designed to control releases from the facility.

They are
manufactured at ISO 13485 certified sites with
bio-compatible raw materials and documented
change control.
Processing conditions can cause material properties to shift from the values stated in the information.

However, in this case, designers
had reduced the thickness of the part wall significantly
to achieve a relative weight saving of 90 percent.
This
meant the raw materials and processing method
needed to be reconsidered.
An added challenge was to ensure the material was
stabilized against potential degradation.
