Injection-blow molding is the best processing choice for producing
the highest quality, finished containers that most consistently
meet close tolerance specifications. The many standard features
built into every Mykas Injection-Blow Molding System, along
with a variety of available options, give you the capabilities
to mold complex shapes and meet high production requirements.
Unsurpassed Bottle Quality
Completely finished in the mold, Mykas injection-blow molded
containers have minimal variations in weight, wall thickness,
and volume. And there's no pinch-off scar from flash to mark
the bottle's surface. Process variations which are commonly
found in other systems using resin regrind are not present in
this scrap free process. Mykas Plastics technology also provides
the high tolerance injection molded neck finish required for
many of the child-resistant and tamper evident bottle closure
Mykas Plastics Injection-Blow Molding Systems process the widest
variety of resins into any shape - from small containers to
wide mouth jars, as well as many industrial parts. Optimal processing
of all resins can be achieved with a closed loop feedback system
which allows fine tuning for consistency in control of critical
injection ram speed, pressures and cavity packing.
High Productivity at the Lowest Per Unit Cost
Every Mykas Plastics Injection-Blow Molding System meets the
economic challenge of high productivity in many ways:
- Providing high cavitation with smaller bottles;
- Using heavy-duty clamping pressures with tie-bars to ensure
uniform clamping pressures across all cavities;
- Utilizing an energy efficient, hydraulic power package designed
for fast cycling with minimum maintenance;
- Offering standard process control that provides energy and
resin savings, faster startups, reduced machine downtime,
and fewer operator running adjustments; and
- Providing a horizontal in-line extruder that allows quick
color change and is easy to maintain.
Options Increase Versatility
The interchangeable heads on these Mykas Plastics systems optimize
cavitation and provide the capability to process a large variety
of bottles of all sizes and shapes, while part removal systems
conveniently position bottles for downstream operations. Hopper
dryers can be mounted directly on the horizontal extruder to
provide better extrusion quality, which is especially important
when processing engineering resins. The optional core rod temperature
control optimizes the processing of all resin types. Heavy-duty
clamping pressures with tie-bars ensure uniform clamping pressures
across all cavities.
Mykas Plastics Injection-Blow Molding Systems are known worldwide
for their reliable performance and outstanding productivity.
We offer a complete range of three-station injection-blow machines
with injection clamp force from 24 to 208 tons. As the largest
supplier of blowmolding machines in North America, our service
network assures processors all the support necessary for maintaining
Horizontal Reciprocating Extruder
The horizontal reciprocating screw extruder provides better
process control of plasticizing, injection speeds and pack pressure.
Mounted at ground level, screw removal, hopper emptying, barrel
cleaning, and other maintenance chores are faster and easier.
This streamlined design also lends itself to faster color changes.
Utilizing the standard horizontal reciprocating screw in its
continuous ram screw rotation mode increases plasticizing capacity
and more gently processes heat sensitive resins. And when required,
the hopper drier can be mounted directly on the feed throat
to provide the best quality melt and save floor space.
The Mykas Plastics tie-bar clamp assembly features heavy-duty
cross arms that ensure uniform clamping pressure across all
cavities. The rigid tie-bar support for the clamp eliminates
mismatch of mold parting lines, prevents mold flashing, and
reduces die-set bushing wear. The tie-bars are widely spaced
for optimum container swing and cavitation. Mykas Plastics has
positioned all operating hydraulics below the table to avoid
oil contamination of containers.
Four individually activated hydraulic pumps work together to
operate the Mykas Plastics Injection-Blow System, eliminating
the need for troublesome accumulators. Each circuit is isolated
and activated only when needed to maximize system efficiency.
The hydraulic tank is located within the machine frame, saving
floor space, and the hydraulics are manifolded, simplifying
The microprocessor control simplifies operation and permits
fine tuning of critical injection ram speeds, pressures and
cavity packing. Utilizing this closed loop controller maximizes
container quality and production efficiency.
The operator can program and optimize the filling speed to suit
the preform shape, the material being processed, and the overall
design characteristics of the manifold, gate and preform. Variations
in resin, hydraulic temperatures, and melt viscosity are adjusted
automatically on a continuous basis by the process control,
requiring minimum operator attention.
The core rod fluid distributor easily and efficiently routes
temperature conditioning water or oil to the core rods, giving
maximum clarity and quality to PP, PC and other containers.
The "Stripper Tipper" strips the bottle from the core rod and
stands it up automatically for easier downstream operations.
Interchangeable indexing heads optimize cavitation and provide
maximum flexibility to produce a wide variety of bottle sizes.
