There are numerous problems that occur most commonly
during the process of injection molding, in such situations troubleshooting has
become prominent to ensure constant production of preform and mold components by
any mold making company. The injection molding process help manufacturing
carved components or patterns with excellence, the process has been evolved with
time to meet the increasing requirements of various industries or applications.
Technically and dimensionally precise range of injection mold
equipment is contributing to produce high-quality components.
Here are some troubleshooting for injection molding
process and its causes:
Blister or blistering: It considers the raised or layered
portion on the surface in the sheet or in the molded part. This is caused due
to high temperature or excessive heat during the process of hot
runner mold. Suggestive troubleshooting measures for this are to set a
moderate temperature in melting state, decrease screw speed and dry material at
increased temperature. Molded Parts can be burned or blistered in the condition
of high temperature, which is sometimes caused by the length of the cycle time
which may be too long. This causes the resin to overheat. Warping of parts
happens when there is an uneven surface temperature for the molds.
Brittleness: It is a condition where molded part breaks or
cracks and the material lost its expected properties. Usually it is caused due
to the bad quality of the raw material and inaccurate amount of regrind. The
suggestive troubleshooting steps for such kind of problem are increase the
melting temperature, check material for contamination, decrease injection
pressure and minimize back pressure.
Black marks or burn
marks: This
considers black spots that appear in the molded part; most probably it is
caused due to thermal damage. Such problems can be dealt by making sure the
high – quality of the material, decrease the melting temperature. Some
materials are prone to thermal degradation, thus it is recommended to use
thermally stable materials.
More troubleshooting can be done by checking the material
contamination as quality of material is important. There are renowned companies
which have efficient preform die
and molding patterns for improved manufacturing of mold components. Acme Disys
is a leading mold
making company that is known for its high-quality designs and precise
components. By configuring and adopting right troubleshooting measures at the
right time, the highest of the production can be reached at reduced cost.
Upgraded hot runner mold have been designed which are further needed to
appropriately maintain pressure and melt flow in all cavities during mold
process. Customize plastic or metal mold components ensure the constant production
of components and create prototype.
