Injection molding
PREPROCESSING
Drying is generally not required because Celcon® and Hostaform® acetal
copolymer materials are not hydroscopic nor are they degraded by
moisture during processing. Excessive moisture can lead to splay
(silver streaking) in molded parts. For better uniformity in molding
especially when using regrind or material that has been stored in
containers open to the atmosphere, recommended drying conditions are 80
c (180 F) for three hours. Desiccant hopper dryers are not required.
Max. water content = 0.35%.

PROCESSING
Standard reciprocating screw injection molding machines with a high
compression screw (minimum 3:1 and preferably 4:1) and low back
pressure (0.35 Mpa/50 PSI) are favored. Using a low compression screw
(i.e.-general purpose with a 2:1 compression ratio) can result in
unmelted particles and poor thermal homogeneity. Using a high back
pressure to make up for a low compression ratio may lead to excessive
shear heating and deterioration of the Celcon material.

Melt temperature: Preferred range 205-220 C (400-430 F) Melt
temperature should never exceed 230 C (450 F).
Mold surface temperature: preferred range 93-121 C (200-250 F)
especially with wall thickness less than 1.5 mm (0.060 in.). Wall
thickness greater than 3 mm (1/8 in.) may use a cooler (82 C/180 F)
mold surface temperature and wall thickness over 6 mm (1/4 in.) may use
a cold mold surface temperature as low as 25 C (80 F). In general, mold
surface temperatures lower than 82 C (180 F) may produce a hazy surface
or a surface with flow lines, pits and other included defects.

POSTPROCESSING
Postprocessing conditioning and moisturizing not required. It may be
necessary to fixture large or complicated parts with varying wall
thickness to prevent warpage while cooling to ambient temperature.
Film extrusion
PREPROCESSING
Drying is generally not required because Celcon materials are not
hydroscopic nor are they degraded by moisture during processing.
Excessive moisture can cause surface defects on the extruded film. For
better uniformity especially when using regrind or material that has
been stored in containers open to the atmosphere, recommended drying
conditions are 3 Hrs. at 80 C (180 F). Desiccant hopper dryers are not
required. Max. moisture content = 0. 35%.

PROCESSING
Standard extruders with a length to diameter ratio of at least 20:1 are
recommended. The screw should be a high compression ratio of at least
3:1 and preferably 4:1 to assure good melting and melt homogeneity. The
design should be approximately 35% each for feed and metering sections
with the remaining 30% as the transition zone.

Melt temperature: 160-220 C (320-430 F)

POSTPROCESSING
Postprocessing conditioning or moistur izing is not required.
Profile extrusion
PREPROCESSING
Drying is generally not required because Celcon materials are not
hydroscopic nor are they degraded by moisture during processing.
Excessive moisture can cause surface defects on the extrusion. For
better uniformity especially when using regrind or material that has
been stored in containers open to the atmosphere, recommended drying
conditions are 3 Hrs. at 80 C (180 F). Desiccant hopper dryers are not
required. Max. moisture content = 0.035% .

PROCESSING
Standard extruders with a length to diameter ratio of at least 20:1 are
recommended. The screw should be a high compression ratio of at least
3:1 and preferably 4:1 to assure good melting and melt homogeneity. The
design should be approximately 35% each for feed and metering sections
with the remaining 30% as the transition zone.

Melt temperature: 180-220 C (360-430 F).

POSTPROCESSING
Postprocessing or moisturizing is not re quired. For thick walled
extrusions (>3 mm or 1/8 in.), annealing is recommended to reduce
internal stresses.

Annealing temperature: 130-140 C (265-285 F)
Annealing time: 10 min/mm thickness
